Don't eliminate the Victron, build on it! The issue is probably due to the dead batteries pulling too much current when the Victron tries to bring them up to 14v. There should actually be a setting to limit the charge voltage on the Victron (your DIP switch method probably didn't get registered because you set the "Save" switch while the power is off, so it wasn't saved at all). Feed that Color GX with some 12v off a portable battery and use it to diagnose the Victron. I bet that Victron is still perfectly usable. Just add a couple of Victron MPPT chargers feeding into the battery and manage both through the Color GX. That transformer in the isolator box is probably for AC smoothing. That cheapo-looking solar inverter probably uses a switch-mode inverter which doesn't handle inductive loads well and that transformer is helping (I guess?). That's another advantage of the Victron inverter - they're quite unique in that they use good old low-frequency toroidal transformers which will comfortably take the abuse of a fridge or an a/c compressor kicking in.

that is correct the dip switchs need to be saved with the power on, the easy way would be clamp the AC out the breaker which i would guess is at 10A bescause it looks like it whould have losted all its settings due to not having power for a long time, the easyest way is plug the laptop in and check the settings and change. if it was closer i would go and do it.

I work for a DNO on Social Media frontline customer service. I remember 10 years or so back there was the first big wave of PV installations. Many of those companies went bust leaving behind all kinds of mess. We're now solidly in the 2nd big wave of PV instLlation. My work has gone from like 10% PV issues to more like 40% & it's the same pattern of cowboy installers there for the easy subsidy money but not intetested in completing the paperwork & leaving confused customers to finish things off. Frustrating for them & for me & my colleagues as they don't really know what they need to do & we're not experts ourselves, though we're gaining knowledge & seeing patterns that help us plan to help customers navigate the process. Using a reputable installer is essential as there are so many potential issues if something goes wrong. I found this video really interesting. Thanks

Hi Jordan, I run a company designing electronics and just wanted to point out that the transformers in those units are 'toroidal' transformers, which are notorious for high inrush currents at power up (but are great for efficiency which is why they are extensively used in audio amplifiers and bench top/performance power supplies). It could possibly explain why the newer breakers in the consumer unit are tending to trip!

@stephensaines7100 Жыл бұрын

Toroidal core inrush characteristics are very easy to buffer in power circuits. In audio, as per OPTX for 'valve' amplifiers...a whole other discussion, mostly around the core material and the annealing properties for the core type. But beside that, it's much easier to get a much wider audio bandwidth and linear response than with equiv EI types. Without a schematic being displayed, I'm puzzled by the size of the toroid in that box. That looks good for roughly a KW @ 50Hz....but it's too small to use for maximum yield, and too large for a voltage control sensing xfmr. Is it being used at a higher frequency chopped feed? (~400Hz or higher?) I note the audio circuit is picking up an induced chop....dammit, show a schematic!

@NigelB-cz9bz Жыл бұрын

Just a thought, but if the 3 batteries are totally dead, maybe the current pull in trying to charge all 3 batteries at the same time is the reason why the system is tripping out. Try putting only one battery on and charge that by itself. Maybe this is the issue? With 3 batteries connected in parallel the total resistance will be much lower, hence the higher current pull.

@stephensaines7100 Жыл бұрын

[maybe the current pull in trying to charge all 3 batteries at the same time is the reason why the system is tripping out. ] That happens, obviously, but any design worth its salt (bad pun) will regulate to a starting trickle for the sake of the batteries as well as the source impedance of the supply.

@hotdeal3156 Жыл бұрын

Those batteries are toast, they want replacing before condemning the victron unit. The DC readings are so bad it’s obvious but you really need an impedance tester such as the hioki 3554 if you intend working with battery storage. I’d of also tested the PV strings for low Riso with a seaward, really the first port of call fault finding solar! You do really nice normal domestic stuff but a lot of learning to do in this area. You sounded a bit condescending of the Victron DIY crowd but trust me, they could teach you an awful lot.

@tonyjover Жыл бұрын

I'm amazed that you aren't more aware of Victron systems. They're not only used in the marine and motorhome industries but widely used in static off-grid situations too. As those batteries were down to less than a volt they're probably terminally sulphated but an equalisation charge from the Multiplus might breathe a little life back into them. For now, charge them up with a dumb charger (no 'smart' charger will charge a 12V battery that's putting out less than around 6V) and then let the Multiplus look after them.

I’m not an electrician but did a DIY Victron ESS setup with zero feed in to satisfy the DIY regs. It’s massively neater than that mess! And so easy to scale! Putting a second array up soon, was very easy to adapt the setup to handle that, and the software “just works”!

Victrons can be configured with dip switches or more commonly, by use of the Victron MK3-USB and Windows/MAC software. I think someone already mentioned the unit was off when you tried setting it, the unit needs to be on. I would disconnect the batteries so you don't draw any load. The Colour Control unit is normally powered from the batteries, and means it still operates with no AC, also worth noting it is not required for operation of the inverter, but very useful to have is it had lots of great features.

You can put the controller and the color control from a 12V power supply as well. But the batteries still probably need to be replaced, as deeply as they are discharged. With such a low power state, the Multiplus likely won't start charging.

Loads of Solar companies went bust after the FIT payment dropped then ceased, these companies relied on getting the FIT payment to survive as far as I'm aware. I know the company that fitted mine back in 2015 went bust. I do have a warranty (not with them). I also have a Victron multiplus2 DC storage too. They're not cheap, but they are very good and can be expanded in many ways and are ideal for boating, mobile home and for being completely off grid.

I would have thought the last place you want to site the batteries is in the roof space. My roof, which has breathable membrane and vents, gets upwards of 40 C in the peak of summer. I would have thought it would be better to put the batteries where they won't be exposed to such varying temps!

Marine electronic engineer here so work with the victron a lot. Some things to be aware of how the power is done for the display cerbo gx downstairs is fine its so it can keep its full history. Be monitored remotely for faults, state of charge tc... when the rest of the system is powered down. In regards to the dipswitch method honestly its awful and not worth setting the units like that, best plugging into a laptop and setting up. But as the cerbo gx is in the system and connected this can be used to set the unit up. This is where you set battery types, size, current limits etc.. So with this in the system from memory this takes priority over the dipswitch settings in the unit so with it connected changing them won't make a diffrence to how the unit behaves. It you need to problem solve one of these best to disconnect the ac out, external control displays etc.. and just have batteries and ac in. In regards to the batteries and the voltage the victron won't charge batteries below a certain threshold even with ac voltage present on the input. So need to charge them separately till about 10.8v before it would kick in. (Have had to do this a few times). In regards to that current limits for the charger that doesn't mean the ac current would be that much less as depends on the ac loads. The reason is on victron units they will still pass ac out as its present on the ac input. Using a laptop or external controller i.e. cerbox gx. you can limit the max current draw which depending on the model can be up to 100a. This is passed straight through to ac out and what ever current it needs to charge. So this means if the inverter is 1200w in this case it actually still provide more current than what it is actually rated to this is just what the unit itself produces when in inverter mode. Also if the victron unit finds the current draw is higher than the current limit then the unit would switch to inverter mode and draw additional required power from the batteries. So I think you said the breaker was 6 amp for the ac in? So if this was going to a double socket and and the ac current limits was 5 amp the current draw demand on it was say 10 amp the victron would then switch to inverter mode to supply the additional 5 amps. This would potentially mean the batteries would never get charged depending on how long the demand was. With the cerbogx you can change how the unit operates so could manually set it from the panel to charger only to top the batteries up. Unfortunately though like I said before if the batteries are to low won't do anything. I can't remember if their is something you can change to stop this would need to dig a manual out. If you ever need help with victron our company is based in Essex so can give us a bell. (Sorry long post 😅)

I think you are a wonderful electrician and produce very nice quality videos... as an industrial electrician working on locomotives (and yes I realize that I am talking with the perspective of pterodactyl verses a peacock) I find that the trouble shooting is way different and yet closely related. I started on one end and worked my way to the other end looking for problems. Like the Victron issue, unplug everything and plug in the unit to mains, flip the breaker and see if it tripped any thing then. Yes/no? You know, the fault finding tree... if everything that this unit is powering is disconnected and it still trips the mains breaker and its own internal breakers then YES the unit is failed, if NO plug something back in to the unit and start the process all over moving to the next component on that line. I would wager that the batteries being in such a state of discharge are asking to be charged over the rating of the Victron unit. Remove 2 of the batteries from the parallel circuit and test again. I do love the videos and realize the amount of time involved in their production and I do so appreciate it!! Sorry for the critique I am an old dinosaur that is sometimes quite the curmudgeon...

Looking at the battery leads, they were linked incorrectly. A parallel system of three batteries should have the charge/ inverter leads joining from opposite ends of the battery set. Pos lead to first battery with links to pos2 and pos3, then Negative lead to 3 with links to neg2 and neg1. The resistance in the leads means the battery electrically nearest the charge/inverter gets more heavily discharged and more charged than that farthest in the line, consequently the setup reduces battery capacity and life.

Also not completely sure if the multiplus is on the MCs register for grid connection, victron are sorting that at the moment. You should be able to get good money for the victron kit for someone's camper van project, but these days I would go for 24 or 48v units, it cuts the cost on the cabling and the possible heat !

At 0.9V, the storage seems to have died from neglect, thereby causing the charger to trip. I would treat each one as a separate battery, attempting to charge with a car battery charger that self limits to 4 or 6 amps. My guess is that they are lead acid, over discharged, and will not recover. Costing your time means the complete replacement is the only economical option for a non-technical customer.

@ianwarren8316 Жыл бұрын

Here is your answer to the tripping Victron! A lead acid battery that’s deeply (over) discharged is normally considered to have lost half its storage capacity! Normal discharge will see the cells at around 2 volts per cell anything much below this would be considered deeply discharged, 6 cells in each battery giving your nominal 12v but in truth 12 v is what they show when fully normally discharged. If the battery ever gets down to 11V is deep discharged and pretty badly damaged! Yours are reading 0.9 V and are fubar! That’s why the victron is drawing more current and tripping. You could disconnect all bar in battery and you might even get it to recover to 11+V but it will never store even a small amount of power ever again. All the batteries need changing and then the Voctron will probably work fine. My guess is the inverter threw the fault the Victron decided with no solar it was pointless wasting energy charging the batteries of the mains and so didn’t charge the batteries and they are now toast

5:39 - I'm going to stick my neck out here and say this is a power factor correction device. I'm not a solar installer, but an electronic engineer. This would be used to correct the power factor (the ratio between real power in kilowatts and apparent power in kva caused by distortion of the sine wave) an uncorrected system imposes a greater load on the utility and lower efficiency as more current is needed to transfer the same amount of power. In this case, the toroidal 'transformer' would actually be an inductor and the other components would be capacitors and inductors too.

I can feel the pain of visiting bust companies installs and fault finding. Also dealing with equipment that you've not installed yourself is challenging. I had to make two visits to a hybrid system get it online and attempt to charge the batteries to finally find out the batteries are not discharging. Left unsure if the fault was with the inverter (hybrid, pv was working), BMS or meter (coincidentally the same type of meter as the one in this vid) and did not have much help form the manufacturer. Considering the system is from 2017 and out of warranty do I attempt to look into the issues further and replace components until I fix the system or suggest a replacement hybrid and battery system. Obviously replace the inverter and start over. Lots of Victron fans here have are being a bit precious, yes they are very adaptable but pretty involved if you are used to standard PV and ESS inverters. Even decent manufacturers inverters go bad and its can be time consuming to find the issues.

Many of the solar install companies went bust due to the way the (Tory) Government handled the FIT rate changes, repeatedly cutting them by massive amounts. This caused big booms (where everyone wanted to get their system installed before the rate dropped), followed by big busts (where the companies that had recruited lots of staff to do the installs suddenly had much less work for them). The FIT was supposed to seed the industry, but actually ended up doing the exact opposite.

I went off grid. Used 2 kilowatts of panels. A cheap chinese 80A charge controller. 6 80A/H caravan batteries. 3.5 kilowatt off grid inverter. When the batteries were full it would send 24 volts up to the 1000 watt/ 24 volt immersion heater. In the end the batteries dead and the charge controller would go wrong and over charge. So now I`ve just connected the panels to the grid with mini grid tied inverters and use a solar immersion diverter to heat the water. I started off with a 4 watt fold up panel lol and a exercise bike with an alternator connected.

Hi Jordan, Great bit of fault finding on the PV. I never think is a very good idea having any inverter in a roof space and particularly batteries due to heat in the summer. In most cases the inverter will reduce output 24:25 to try and reduce heat - just when you need it!! As the batteries were totally flat - it may be worth disconnecting 2 out of the 3 it seems if that helps.

Obviously I deal with DC voltage on cars so I’m not sure about solar and the DC batteries but car battery chargers these days are a bit more sophisticated than before and I’m wondering if the AC charger is similar. When charging a car battery with a good quality charger, if the battery voltage is lower than 2V there is usually a button that needs to be pressed to tell the charger that there is a battery connected and that you have connected it correctly (+ -). If the battery is lower than 2V and you just connected it to charge it does just switch off. I’m not saying this is the problem in your case but it may be worth checking. 👍👍

Back in the day, when the government introduced the feed in tariff system, there was a huge surge in demand for solar installs. Loads of companies sprang up to to service the demand. years later the FIT system was cut back and eventually ended, the demand slumped and many of those companies folded because there wasn't enough business for all of them. I had solar panels put in in 2011 which was around peak demand. The company that put them in folded around 2018. Mine have "hung in there" and are still going, but if they ever pack up I'll have to find someone to sort them.

Hi Jorden. You should connect the negative cable of the victron inverter to te last battery and not to the first one as it is now. Now the cables to the first battery are shorter than the last one, so for the last battery the resitance is higher, therefore is battery will give less power than the first one. So connect the positive (RED) cable to the first battery en de nagetive (Black) to the last. Make shure that all the jumper wires are exectly the same length. Also, because the battery are completly dead now, you may have te charge them first one by one so the charge currect will stay lower. Maybe is easier to do this with a external battery charger.

Put a Solis hybrid inverter in. Not only will it run the whole house off battery when the grid is up, but if the grid goes down, it will still keep that socket connected to the victron running on battery. Simple to install, quiet passive cooled, and reliable. Takes standard 48v LifePo4 batteries so you're not tied to one manufactures proprietary expensive battery.

@andrewrobinson395 Жыл бұрын

The batteries are in a state of deep discharge and possibly faulty. The Victron multiplus will not charge a faulty battery and will activate its protection. The way the battery bank is currently connected is wrong, in it's current configuration it will lead to uneven charging of the parallel bank and eventually failure. Both charging/supply cables are connected to the first battery. The correct way is to leave the +ve cable connected to the first battery but the -ve cable must be connected to -ve post of the third battery. This will ensure an even charge off all three batteries. Battery health should have been checked before attempting to charge them, impedance/conductance test with a proper battery tester should have been carried out to see if they are still in spec. Batteries are dangerous and can explode. I like Victron their kit is modular, I have seen them supplying factories in countries that have unstable grids prone to frequent load shedding, as well as off-grid homes and resorts. Technical support is pretty good as well. Enjoy your videos.

I remember being interested in getting into working on solar installations back before the feed in tariff boom. Solar installers were hard to find. Then suddenly as the 42p feed in tariffs arrived, the internet was awash with solar installer websites, all claiming to be experts....I joined one of the better ones, but the regs were still shaking down for this "new" tech. Suddenly the bonanza was over and most of the companies disappeared as fast as the arrived... the upshot was a legacy of very poor quality solar installs, many no longer functional, and no back up for the customers. A lot of wasted equipment and money...not very green....Seeing your quality of work is encouraging, but sadly there are still many awful installs and lack of maintenance, particularly on new builds where the developers are just ticking the green boxes to get their plans approved.

Frankly I was the lucky one, as solar edge replaced their inverter and 3 optimisers FOC. The whole debacle cost me just over £2000 that’s scaffolding and repair of the system. The chap who came out said that lots of cowboy companies set up and a few years later went bust. He spends a lot of time fixing other people’s bad worksmanship.

Glad to see some other Victron folk on the replies. Seems dumb having a 12V 1600 AH Multiplus (my Caravan has a 12/2000/80) in a house... The Batteries are probably beyond recovery. Try just one battery. They are also wired wrong - the first & last batteries should have the two separate (+/-) connections to the Multiplus. Personally, split the main circuit breakers into two systems, Grid & Essential. I'd change the Multiplus to a 48/5000/70 and put it between the two halfs (Grid & Essential). Move it down stairs too. Add about 10KWH of LiFePO4 batteries (@48V) to the Multiplus. Add some appropriate MPPT controllers to the strings and get them to charge the Batteries. Life will then be much better. I'm probably way too late with the advice - a Followup video would be great!

@richardbartlett7226 Жыл бұрын

Matt:e devices like that PV+ is designed (as you read out) with Open-PEN-like functions to watch for overvoltage. The autotransformer within it is designed to lift the voltage from the PV generation (the opposite of an optimiser). The theory is that when the inverter output from the PV is lacking or fading to a non-production/shutdown-state, the matt:e output is exaggerating the voltage and therefore able to feed into the system for slightly longer than if the voltage was left as stock. The isolator switch providing a convenient function that might have used up that space with something one way or another. Snake-oil? Perhaps that depends on how light levels improve with hotter summers and dryer winters. Thought to add words about this feature here in case you thought you were missing a trick. Much depends on what price they go for and what functions already exist in the hybrid inverter that has been selected and whether you get your isolators from a top-tier £xxx vendor or a more generic brand.

If the batteries are down that low, chances are they are toast, and the 'charger' won't be able to recover them no matter what the settings are. If you can get even one healthy 12V battery even just temporarily connected, that should prove the Victron unit.

Are there any industry member organisations they could join that take over their warranty obligations in the event they liquidate? Also, not sure about the UK, but in NZ the consumer gets to choose who to deal with on issues surrounding durability, well beyond any explicit warranty - you can go to the local importer/distributor or even manufacturer if they have a presence. And that will cover incidental costs too, such as labour, where the equipment has proven to not be reasonably durable.

From what he shows it's almost certainly the batteries that are dead/extinct/kapput/had it... replace those (with Lifepo4 as they're now cheaper than Lead Acid) and sort out a suitable breaker for the likely current draw from the Multiplus, and make sure it's configured correctly... and it'll outlast the other equipment ! I would NOT be recommending to the customer that it's all ripped out and replaced on the basis that I didn't understand it.

@johnwarwick4105 Жыл бұрын

Are you sure that voltage optimiser unit doesn’t try to keep the voltage below 250 before it cuts out. Along with some friends we had solar installed on our properties in a rural locations way back when it first came out years ago. We quickly noticed some systems were performing better then others in mid summer. Long story short ( I am an electrician) some of the properties had high incoming supply voltages 250 plus. What was happening is the inverters were tripping on over voltage when at full output. The easy fix was a voltage optimiser to drop the incoming supply either to the whole house or just the solar. From memory the highest supply got to around 258v. Anybody doing work on old farms often find the supply is always on the high side. Presumably to allow for some volt drop when under high loads😂😂

@narrowboatlongpod4176 Жыл бұрын

Boat systems are typically 12V with an inverter used to produce 240VAC for "normal" domestic appliances. The batteries are usually charged from the engine and/or solar. So, the system is 12V and everything, including the Color Controller, is wired into 12V. When moored in a marina, it is very antisocial to run your engine to charge the batteries so the MultiPlus does two things. It feeds 240VAC directly to the AC devices and charges the batteries, usually from a 16A supply. It is also quite common (and highly desirable) to isolate the incoming earth from the boat's earth and this is done with a galvanic isolator or, better still, an isolation transformer. On a boat plugged into the mains, the MulpiPlus acts as a big uninterruptible power supply and will switch the 240VAC to the batteries via the inverter if the mains goes. It is also quite clever and can assist the incoming mains if more than 16A is required.

@sanders3219 Жыл бұрын

The batt system is AC connected and will only charge if there is overproduction. If the PV inverter didn’t work the batteries got drained and died. The Victon is prob still oké. You could connect the two strings as a poly-string on one mppt tracker. The max string current Will be exceeded, but this wont matter because of the east-west oriëntation of the PV-modules.

@djsmiley01 Жыл бұрын

The Cerbo and Victron are great pieces of kit, and the install is, in theory, working, but the design is wrong. Using excess solar to feed the Multiplus is fine, and the MP will adapt the charge to available excess. During night, the MP can act in reverse, keeping the grid net to zero. (backfeeding) from the batteries. Major issue in this case is using lead-acid for cycle usage: you will kill them soon. And if the MP has no way of measuring the SOC (either BMV or Lynx) it can't see sh*t, nor can it keep the batteries to get too low in charge. This would work fine with lifepo4, but 12V is uncommon (most setups are 48V). Also, the MP compact is not within regulations for backfeeding. You need the MP II (double grid disconnect), but certification for UK is currently pending. For all Victron gear: Get the MK3 USB to fully configure/monitor the Victron. In your case: The CCGX can be connected to ethernet so you can configure the MP using the Victron VRM portal.
