Victron Multiplus II & Pylontech Home Storage Battery. A real Tesla Powerwall alternative
Рет қаралды 46,217
Күн бұрынDoes the Victron system perform as I hoped?
Was my list of wants and needs fulfilled?
Battery has been live during May so I now know how it really performs compared to what I hoped for. Is it still the ultimate Home Storage Battery solution and can it compete withe the brilliant Tesla PowerWall?

Thanks Nigel - very informative as usual. Would definitely like a video on how to calculate battery storage - have had a couple quotes from installers but their estimates seem a bit random. Cheers

Hi, battery size depends what your objectives are. I have a heat pump, so thought the more the better, but in winter there is no significant solar production, and therefore charge the batteries on an off peak tariff. The longest off peak period I could get was 5 hours, so I sized my batteries for 5 hours at maximum charging. In summer my solar panels completely charge the batteries and then export, but I can’t afford any more. So I’ve ended up with 6 x 3.2kWh batteries, just under 20kWh. I don’t use 20kWh in summer, but in winter use 40kWh, so it’s a compromise.

@@Muppetkeeper Hi MK, thanks for helpful reply. Hadn't thought about off-peak charging capacity in winter and so far only really considered what solar I'm not able to use and could therefore be usefully stored. So much to think about in this game! Practically, to start with I think it will come down to what I can afford, then assess overtime and increase number of batteries later if budget allows. Interestingly both installers quoted for 7.2kW - maybe this in industry norm for a standard house (or they had 3 pylontech 2.4kW batteries going spare!!). ☺

Very interesting video and set up. I can understand the desire to minimise grid import to zero, but in reality I find it adds up to little cost with my "cheaper" system vs the additional cost it would take to remove the issue - a cost benefit thing to take into account really. On days where the battery lasts all day (almost always at the moment) I import between 0.8 and 1.5KwH a day (not counting off peak use). About 20p at current rate, or say 45p when rates go up. It's a trade off.

Thanks Nigel you must feel very satisfied, years of work delivering a competent system. As you say, everyone needs to work out the the storage solution that meets their needs. If you can do a video on sizing that would probably be well received. Another subject that I find people are confused by and it is not helped by a lack of experienced installers is understanding the system at the next level of detail. Anything further on listing the components used and maybe a more detailed schematic of the system would help a lot of people. I suspect there is still reluctance with a lot of people in starting a conversation with a supplier because they don't want to look dumb. Perhaps they need to go back through your past shows but you know how people are! Anyway what I really wanted to say was CONGRATULATIONS on winning at the EV Puzzle. I suspect you won't stop perfecting but a little self congratulation is well deserved. 👍👌

Welcome to the big battery club Nigel Our Powerwall takes 1.4 kw from the grid each month as it checks connection to the grid daily. It gives 5 kw peak power but doesn’t give you much control on when you want to charge the battery from the grid during the winter (as John Tisbury referred to) You have more capacity, (you can’t have too much), you have similar peak output and far more control over it and can add even more capacity if you wish. As soon as the solar starts to diminish in the autumn you will soon escape from your current ‘lazy’ ways.

You will find that those battery packs are in reality well over the stated KWH capacity, this is how they can boast 95% discharge which would actually kill a lithium battery cell. Similarly charging to 100% will be well under 100% in the internal cells. This is done to reduce stress on the cells and increase lifespan. Cheap battery packs don't do this for obvious reasons and their lifespan is severely reduced because of it. You have a pretty good setup there, quality components that cost more but will be far more reliable. The Victron inverter is also one of the best with many useful features not found on cheaper alternatives.

I have the Multiplus but the GX version. I'm just playing at the moment and it is wired purely on the input only, I only have a 4kW array of solar PV. I am using a CT clamp to measure the total mains input and found that if the Victron batteries are fully charged and am producing enough solar to allow the Zappi to start charging on Eco++ then when a cloud comes over then the Victron will keep the minimum charge rate on the car going, so by moving the CT clamp to measure just my consumer unit and not the Zappi it stops the Victron from powering the Zappi. Somewhere in that explanation could be the solution you're after

Excellent solution, I'm glad to see that you are happy with your Victron solution as am preparing to fit all the components already purchased, all Victron including the 5000/50 multi, Victron shunt, distribution, and Cerbo GX so I was listening carefully to both of your videos before installing it all including my 12 x 400w 10A Perlight Modules. I cannot fit more modules in the garden because the hedges on both sides would shade too much but I might eventually install more on the roof of the annexe that I am currently building. As far as storage is concerned, I was looking at the 48V 100Ah LifePO4 battery Built-in BMS 5.12kWh from vladsmall and see how it performs after which I might stretch to one or two more. However, living alone, I don't seem to use more than 1.5kwh on a daily average over the 365 days although I will need more when my lab is ready. I hope to see your next video soon about the capacity meanwhile thans once again 🙏and keep up the good work 😉

I have a 7.4kw solar and a 6000va 3phase inverter and looking to get some battery storage. I have checked with energy monkey who are quite local and stock all the components in your video. My consumption apart from normal household is a 3phase ASHP and Zappi so looking to do your solution on each phase and possibly add some more solar panels. I stumbled across your channel as I was originally looking at GivEnergy this makes more sense as I can place the batteries in the loft, fairly evenly spread out the weight.

Thanks, Nigel for your video series. My Fox System is soon to be going in and I did a lot of work on the sizing. i don't want to size for the worst-case winter's day 16 kWh (excluding EV charging) but provide ESS to cover the base load and then some ie what I would need on an average spring/autumn day with my 4.8 kW PV. I'm happy to export during the day or charge my 10.5 kWh SunAmp Heat Battery (Heat Store for DHW) in summer and in winter and top up the ESS and Heat Store from off-peak EV tariff in the winter. The PV calculation is that it should meet 50% of my current annual consumption needs and I also have invested in Wind-Farm co-operative to meet the other 50%. The Windfarm element means it wouldn't pay me to eliminate Grid import as I need this to collect on the Wind-farm payout.

Hi, thanks for the system update. A question on your battery SOC monitoring. Does it take into account the depth of discharge (DOD) of the battery? For example, my battery may indicate it is 100% full, but with say, a DOD of 20%, it has a usable capacity of 80%. I scaled my monitoring system so that it reads more correctly, i.e 100% SOC = 100% usable and 20% SOC = 0% usable. It gives me a much better view of how much charge I have left.

In the video channel by Will Prowse, he has created several videos in which he looks at how batteries in a stack discharge. Across the videos he seems to have compelling results that show without some thought, one of the batteries will charge/discharge more frequently which is likely to shorten the life of that battery. Have you done anything (do you need to do anything) with your stack to ensure the batteries are used equally. Or do you think its doesn't matter much?

I guess the 3000 unit means the peak power will be the same (I have it limited to 2400W). The battery sizing review would be very useful - but I have an idea of where to start as I have my import figures for the last year (with a 5kwh battery).

I have 4.4kW solar array and a Powerwall and Zappi. Domestic heating by Gas Combi boiler. Trying to reduce my carbon footprint, I've now installed a hot water cylinder and immersion heaters, and an Eddi. Its plumbing is in parallel with the gas boiler, with isolator valves so I can switch either the tank or the boiler into the water circuit. So far it looks like I won't be using any gas at all during the summer months because the Eddi heats the water during the day, or overnight on my Octopus GO cheap rate grid electricity which is cheaper than my gas tariff. My next stage is to look at the room heating. I'm thinking Infrared heating panels rather than air source heat pump because my 3 bed semi has limited space for installation of the outdoor unit. I'm in no hurry to move, will probably wait until the gas boiler dies of old age. Also my wife is not fully onboard with this change yet....

Hi Nigel, interesting conversation. Did you get your Zappy not seeing your battery issue sorted? Also I was confused about your explanation of your consumer unit being all on AC out1 (the protected side of the Multiplus 2). My understanding is that the 50A capacity of the Multiplus 2 is total draw across AC out 1 and 2, and that the total draw of AC out 1 when the grid is offline is only 20A. can I assume that you have not had a power outage and tried to turn on multiple high voltage loads (eg cooker, water heater and aircon)? Take care D

Great video. I am currently ooking for an AC coupled inverter to add to my house energy store. I have installed an AC coupled system in my brothers house, using our own built battery of 10.5kwh from a nissan leaf reclaimed battery. Could you by and chance answer a question on the victron. The inverter we bought was is alittle slow reacting t house loads. Ie, when the kettle is switched on the inverter sees the oad then over period of 30 seconds then takes the load from the battery to supply the kettle, but in the first 30 seconds the grid supplies the load. Info from the manufacturer s that they have designed it this way to protect the power FET`s on the AC supply, and to aid to the inverters longetivty of life. What is the reaction time of the victron to a heavy load like a 3kw kettle being switched? Does the victron immediately supply the load? Thank you.
@craigchamberlain Жыл бұрын
Anthony, I’m in the process of procuring a Multiplus-II setup similar to Nigel’s and from what I’ve read, the inverter is very fast to respond to both an increase and decrease in home load while minimising import and export. This is especially the case if you use the optional CT clamp. This CT clamp connects directly to the inverter rather than via the GX device and so can respond faster than if you use the ET112 energy meter. From what I understand, the response time is a few seconds but happy to be corrected if I’m, mistaken. I think there was a thread on this topic on the Victron Community forum which I would recommend joining if you haven’t already. Just search for Victron Community and you’ll find it. HTH.
