@eliotmansfield Жыл бұрын

They are not without their problems - another tuber has identified an issue when you start a load with a high inrush current it causes the outputs to oscillate which can kill any devices that use a capacitive dropper for thier power supply - ecoflow seemed uninterested in the issue and more interested in finding gullible influencers to push the product. Wrt to the wiring, i’m sure you know that you should create a dedicated sub consumer for your critical loads along with a bypass switch (to bypass the whole battery system in case it goes tits up)

Well that's one system that's completely against reg's......Where is the neutral earth bonding relay and local earth electrode - required for operating in Island mode? From the SHP manual: 'NOTE: Please follow local code requirements with regard to bonding neutral and ground. Bonding should be done at the first means of disconnect, which is the service panel, NOT the SHP' I'm not keen on this system here in the UK - it doesn't work properly with RCBO's/RCD's as can be seen here and is obviously not designed for our market....it is cost prohibitive anyway.

In answer to your question - not very it seems.

@blower1 Жыл бұрын

As an addition to this, I can't see how this system could ever be installed and be compliant in the UK without the SHP being redesigned. It requires a neutral earth boding relay - but this relay/contactor MUST be interlocked/mechanically linked to the main contactors that switch over the maintained load from the grid to the battery inverter: _Timing of the operation of the island mode isolator and N-E bond relay should comply with Regulations 431.3 and 537.1.5 of BS 7671. This requires:_ _-The N-E bond relay to be interlocked, or mechanically linked, with the island mode isolator._ _-When moving to island mode, the N-E bond contact is closed immediately after the live conductor contacts of the island mode isolator are opened_ _-When moving to connected mode, the N-E bond contact should be opened immediately before the live conductor contacts of the island mode isolator are closed._ There is no way to do this on this system as the relays that are switching the loads are proprietary and not standard parts that could be modified. You can't even fit an external contactor to try and accommodate this - as the whole system is designed to control individual loads. For it to work according to the regs you would need a main transfer contactor from the inverter/grid that supplies the individual changeover relays and this contactor would need to be interlocked with another for the N-E bonding - which just can't be done on this all in one 'smart' panel. As such this system, as is, can never be installed compliant to the regulations - why they are selling it in the UK without having checked to see if they are even compliant, is disconcerting to say the least!

My initial thoughts on watching this video (as a retired DNO engineer) - in no particular order - Assuming the DNO supply is TN-C-S or TN-S and an earth connection has been offered and connected, it's an absolute requirement to have a measured earth electrode installed and connected to the MET for any alternative (ie switched standby) or additional (ie interconnected) source of electrical energy. One may have already been installed here before the video but we're not told if this is the case or not. When part of the installation is being fed from the battery, how are the neutrals in the energised circuits referenced to earth? Is there an neutral/earth contactor in the Smart Panel? If there is, does it affect the neutrals on the circuits not designed to be energised by the battery? As you discovered (and as the manufacturer states in small-ish print on their website) the Smart Panel circuits should not be connected downstream of an RCD or RCBO. Despite rearranging the circuits in the dual RCD DB, can you state that final circuits that _should_ be protected by an earth-leakage protection device (according to BS7671) will continue to comply with that requirement? Do the relays in the Smart Panel achieve galvanic separation between the battery and DNO sources or is it a semi-conductor device? How can separation be tested, for example, by checking the IR of the switching device? How can safe isolation be achieved for working on any of the circuits routed via the Smart Panel (other than obviously disconnecting the Delta PRO or other Ecoflow device)? Although the changeover time may seem impressive at 20mS, I can see potential issues with these devices on installations supplied via rural DNO networks with auto-reclosing devices. If I was using one, I would not want it to re-energise any circuits until I was confident the DNO reclose sequence had completed/locked-out (typically within 1 minute). Rapid switching of inductive loads on the installation could be asking for problems caused by over-voltages due to back EMF. Unlikely but still not impossible. ENA ER G99 requires clear labelling on the equipment to the effect that the installation is capable of supply from more than one source of electrical energy. I'm still wondering if this set-up satisfies the requirements of G99 or not. If BS7671 isn't satisfied (earthing of the installation neutral or final circuits missing their earth-leakage protection) then G99 isn't satisfied and neither are the Electricity Safety, Quality and Continuity Regs. What are the performance characteristics of the circuit protection devices in the Smart Panel? Are they similar to a Type B MCB, for example? The use of backup generation (in my experience) seldom takes any cognisance of the fact that the alternative source of energy in use may actually be incapable of supplying enough current to operate the protective devices relied upon during a fault. Finally (for now 🙂) there is the question of the cost of these devices. A single Delta PRO retails at £3500 (for only 3.6kWh !!!); a Smart Panel £1700. Eye-wateringly expensive before they're out the cardboard box! Add to that the installation of a measured earth electrode, juggling of circuits in the DB plus testing etc and that is one huge chunk of change! 3.6kWh isn't going to get you very far. Thanks for making the video though.

There is no neutral/earth contactor, i.e., a neutral earth bonding relay in the smart panel as far as I can tell as there is a reference in the manual to this area: ' Please follow local code requirements with regard to bonding neutral and ground. Bonding should be done at the first means of disconnect, which is the service panel, NOT the SHP (Smart Home Panel)' As such, and for the other reasons you stated such as no local earth electrode - this setup does not confirm to the reg's surrounding generators operating as an alternative supply nor the IET code of practice for Electrical Energy Storage Systems, for such equipment operating in island mode.

Jordan, both RCDs tripped because both were seeing an imbalance. You had 2 circuits on the right-side RCD consuming current but the panel neutral is on the left-side RCD's neutral bar. This creates the same current imbalance in both of them when it switches over. The backup battery would have to switch over faster than the RCDs can react to avoid tripping them, and 20ms isn't anywhere near quick enough.

@barrieshepherd7694 Жыл бұрын

I'm not a qualified sparky just someone who has grown up more or less understanding the issues. As as I watched the video three things were in my mind; what stops inverter feed causing the existing RCBs from popping, where is RCB protection, for the sockets when on inverter during a 'blackout', and what isolates the inverter output neutral from DNO earth - which you bonded across to the main house/DNO earthing. Unless I missed some wiring/relay info it seems that the inverter input and output neutral is also bonded to the 'rest of the house' neutral when in blackout mode and on to the DNO distribution. Switching off the main breaker does not simulate a blackout as it will also disconnect the DNO neutral connection. Seems to me that to get anywhere near to safe compliance there needs to be a dual pole isolator to disconnect the DNO supply fully while on inverter operation (along with sensing to revert when power returns) To me this device seems totally inappropriate, in its current form, for use on an ordinary UK domestic installation - what compliance it is claimed to have would be an interesting question. I was not that impressed by The EcoFlow advice in regards to 'getting it to work' by messing with RCB positions (or even taking them out of circuit). I could think of better ways to connect it but that, as you say, would require a second CU, for the circuits to be protected, and a dual pole changeover arrangement - but it would be safer! Looking forward to JW's observations 😂😂

I'm a bit concerned about placing that unit with rather big cooling fans in such a confined space. I'd have a new door made for that space with ventilation slats from top to bottom. With the storm outages that we have in the USA quite a few homes now have backup generation. The neatest solution is to go somewhat large on the backup power source and then have a single main transfer switch that switches everything between utility power and backup power. That way you don't have to touch the existing breaker panel. There are options available to automatically disable high demand circuits if desired. And it often doesn't cost that much more than a medium solution that only backs up some circuits. I used to just rely on a portable generator to keep on the lights, refrigerator, heat and the basement sump pump. It was better than not having any electricity, but after going through a 4-5-day outage I found that I was still roughing it - a lot of food I couldn't cook without an oven, no hot water to clean up, and I couldn't do laundry. Not to mention that when your house has power during an outage you can easily get a few house guests. So, I'd avoid the middle ground - either do the minimum to meet basic needs or spend enough to be fully comfortable.

In order to run the whole house with a main breaker, you would be looking at ~$4500 US for the generac generator & transfer switch plus ~$6500 US for the installation of an 11-14 KW back up system. So yes for $11K US you could fully back up your house with a NG or propane whole house generator. I assume that if you had NG, you would be able to heat your water and run your dryer on your current portable generator. So, if you used this Ecoflow system, you still would not be able to use your electric oven. It is 30 amp max at 240 and your oven would need 50 amps. But the Generac whole house system would do it easily. We have NG for hot water and central furnace so we could run a system like this. Our 3600W inverter generator can run our house too, except for the electric stove. We may change that at some point, but for now we have the camping stove if needed.

Questions/thoughts on this really interesting video: 1) Since this is wired in after the MCBs, what circuit protection is there when the system is running from the battery? - it looks like there is none and you'd really need a second consumer unit with MCBs to ensure there is MCB protection if running on battery. I wonder if this might help with the RCD situation, i.e. have the RCDs in the second consumer unit which would be fitted downstream of the smart panel and not have an RCD in the upstream consumer unit. 2) If someone turns off an MCB thinking they have isolated a circuit, it can presumably still be powered by the battery - is this a case of hoping the person switching off the MCB also knows to turn off the battery or is there some other protection?

27 grand just for the equipment to get through 3 hour blackout time slots seems a bit excessive but there is the potential for the time slots to increase if the national grid requires it. I hope the owners think of solar too. For those on a budget you can get 2.4k Wh for £999 but with 1000w inverter in the EB 240 but I think that sale ends 28th December. For roughly the same price you can get an Echoflow Delta with a more powerful inverter but at around half of the battery capacity of the EB 240. There's a lot of options for mid-range too or to build your own. I think it's something people should think about but if not, get the candles out and enjoy the disconnect from the tech we've grown so used too.

I am a UK electical engineer, I do think the whole concept and video is very dangerous to promote without first understanding product limitations and secondly understanding how split load C.U. are actually configured to give RCD grouped protection when feed thro the DNO metering and cut out (PME) . So the interconnections were completed in the fashion that seems to make basic sense but then when the whole system is switched on, the dual RCD's both switch off immediately in the existing C.U. which frankly isnt surprising to me as 1. the RCD is upstream of the back up supply from the ECOFLOW and 2. the MCB's will be actually isolated by the ECOFLOW individual relay device which is also a electronically controlled circuit protective device (MCB) but remotely controllable as opposed to manual switching MCB. So in a power outage situation neither the MCB or the RCD is actually doing anthing whist the mains supply is OFF or unavailable due to power outage. The video shows the system with the DNO supply live and then the Eco-flow battery system being switched into inverter mode. Thus the SLIT MODE RCD C.U. sees the neutrals from each side of the split board causing an imbalanced coil current load leading to RCD tripping out as it should. The problem with the concept and design is it would never give RCD protection, it would never give isolation from the PME supply thus causing live conductors to be exposed to another source of electricity which could be back feeding to the MAINs sub transformer network giving potentials for DNO operators attending sub stations to be exposed to voltages which would normally not exists on tripped outgoing terminals in the substation MCCB's. WARNING SIGNS ABOUT ALL SUPPLIES MUST BE ISOLATED BEFORE OPENING PANELS ETC PLUS Interlocked change over contractors and rotary isolators would be a requirement in the UK just for basic isolation if anyone needs to isolate power for any reason including testing and inspection or work on out going circuits.

A bit late response but here it is. If I'm not mistaken then ideal solution would have been to install additional consumer unit, one that is before smart panel (or upstream) and another that is after smart panel (downstream) that is on battery back up. This way you should be able to maintain the RCD in all cases. Personally I have Deye hybrid inverter at home (PV + battery) that is installed similarly or essentially the same way whilst all my RCDs are still functioning as required. A bit intrusive installation that requires additional effort in time and materials but end result is very good: faster takeover times, you can choose what has battery back up and what does not, configurations and etc.

@@mattwhitley9315 I'm in agreement with Craig Butler below that I am sure they have gone back and replaced the 16A for a 32A MCB.. The purpose of my comment was that it is the cable current (max current that keeps the cable below the insulation melt temp. For normal twin and earth this is 70 deg C) that limits the MCB current rating. By downgrading the max current flow in the settings the customer gets a working system that will not trip the MCB until they come back and replace the 16A MCB. My opinion is that this was configured this way so there was a working system. Unless you were on very limited time of day tarrif then taking a bit longer to charge wouldn't really matter and if this is for power cuts only then a few days wouldn't be a massive issue - again in my opinion.

Never forgot that. Purchased a Generac xl5500 for electricity, kept the kerosun heater, have a camp stove for cooking, 20 gal of kero, 27 gal of gas, 20 lb of propane just in case, if this happens again.

Bit confused here, but what I think this means is that there is no MCB or RCD/RCBO protection for the backed up circuits when they are on battery as the battery is inserted by the ecoflow box after the consumer unit, I understand there’s a backup fuse, but that’s a poor replacement for a modern consumer unit. Also agree with the comments on earthing. That said I’d say with different wiring this would be fine, just not happy with it as connected.

However they are out in the open so most of the time you can just stand there and access them at shoulder height or lower. Most newer homes they are all flush mount as well. This can cause issues like you adding kopex here, you can't do that very easy when they are behind the sheet-rock. So there are some logistics that make things tougher for sure as most will be in wall for cable runs for example adding a new circuit. One set of problems traded for another set of problems. 🤠👍

I come at this from a different angle to most commenters to this video, who are quite rightly focussing on the electrical side and safety etc. I am someone who’s constantly seeking ways and means to utilise solar and also off peak power, to manage energy costs. In my own home, I have invested in solar, tesla powerwall, air to water heatpump and air to air heatpump for air conditioning. I have an EV and so also have a myenergi system Eddi for hot water and Zappi for EV charging when there’s spare solar this set up works brilliantly and my total energy bill including heating/cooling and EV charging has been around £700 for last year - even with sky high energy tariffs. I also have a static caravan and what I would like to do is replicate much of my home system using the EcoFlow Delta Pro… This video is the first I’ve found in the UK that shows how you COULD insert the Dela Pro between the grid and the property to manage input feeds i.e. grid, solar or even generator and output feeds i.e. the caravan or indeed charging the EV. While this isn’t yet a full robust solution, it does take us most of the way… EcoFlow are pushing the boundaries wanting to go beyond simply delivering an off grid solar generator, to a fully integrated solution and I commend them for this. I look forward to further videos on this subject and if you guys at Artisan Electrics, want to use my Caravan in Wales as a guinea pig install for and “off grid” and grid tied integration I’d be up for that!

My guess is that he’ll go back and tidy up the loose ends there as Artisan take pride in their work. Also how would you then do an EICR would you test from the connection at the consumer unit to the UPS board or at the cables coming of the ring main / radials? Am I right in saying that the power comes out of the MCBs into the UPS and then back out again in which case the UPS is part of the circuit. All seems a little up in the air for me.

Q, is it possible that this isolation (or lack of) is the cause of the tripping (in reverse).? a balancing issue.? Remember, the inverter Neutral might not be providing a low resistance bond to the CPC Earth potential. Causing the RCD / RCBO to wrongly detect.? Its all new, and needs some work. I would have thought a similar idea to the automatic change overs to Batteries had to be covered in the Solar panel industry, this also involves an inverter, that doesn't naturally have its Neutral bonded to the CPC/ Earth either.!?

Even if the CU RCDs were to trip won't the battery backup now simply keep electrocutng the customer? Also flipping the CU isolation switch isn't the same as a power cut where the grid goes down but remains connected - it wasn't clear if your final wiring solution avoids the possibility of back feeding the grid. The point has been made about a TT earth for when the TNCS cable is severed. Also curious about the maximum load from the battery?

The RCD is tripping because you're sharing a neutral with the grid and some current is leaking that way instead of back to the ecoflow. It's the problem when your relays only swap the live. It's why you either need a 2-pole relay to swap hot/neutral or you need to create a neutral that is isolated from the grid and feed your backup panel with that (e.g. using a centre tapped transformer when you have 2 out of phase hots coming in). I learned this the hard way when I had a GFI equipped inverter feeding hot only swapped circuits. There's really no "easy" way around this short of just moving the backed up circuits to their own panel and isolate the grid neutral when the inverter is on.

Neutral bonding / switching is the problem with the RCBOs. You can not put a generator after (upstream) an RCD device.

Or, you need individual RCDs after the ingestion point, where the Wagos went.

Not so sure how I feel about having a semi-island mode where it's shoving current down the suppliers PME instead of cutting the incoming earth off. As the neutrals are still going to be in any case returning from the circuit, into the rcbo, into the neutral bar and down the suppliers cable + two neutrals back to the Ecoflow.

Not a spark but changing RCD’s RCBO’s for MCB’s is backwards when we are looking at AFDD’s now! The better way would be if the unit could have supported 100A and run the grid through that and then to the consumer unit as just like tails to the mains switch on the consumer unit to backup the entire board. Bad points with this setup it doesn’t support Solar, so your reliant on grid charging and off peak charging and a small battery like that is going to be dead in no time, then your drawing peak power which defeats the point of the off peak grid plan, and for just backup power it’s not worth the money that that cost, Proprietary change cable for the battery meaning he has to be close to that unit . But just my two cents no RCD/RCBO protection sounds like a bad idea from someone who’s not a sparky.
