Or Two-In2-One does Go or in this case Give.

Cheers mate

There is an argument some make for a single socket in island mode not to require a reference earth. Not a chain of thought I buy into tbh.

@@electrician247 bearing in mind i’m not that experienced in installing these systems, I was under the assumption that you had to switch from using the DNO earth when in island mode even for just a socket outlet. Only had a quick flick through my copy of the code of practice

@@SME_Ste the DNO Earth can be maintained as per the COP but should be supplemented with an electrode to form a TNS on the alternate supply in island mode. However debate is their regarding single points of utilisation and IT earthing systems. Manufacturers and installers can, do and have made that case. It’s never colour by numbers with hard and fast rules on any of this tbh.

@@electrician247 Cheers Mark. Getting into these new technologies and understanding as a one man band is hard. Got to be installing them on a regular basis really to get a full understanding, training course are all good, but as with everything, experience is key.

@@SME_Ste very true mate.

The AIO can be installed with only a canopy. But you will see reduced performance in the cold and hot weather.

​@@electrician247 thanks Mark.. I think I need to hold on for the new Anker aio by the sound of it then I've heard that's been tested for all weathers. Wonder how much it'll be🤔😏

@@judebrown4103 many of these systems are rated for -20 +50 but nearly all will say a recommended range of 0-30C This is an unavoidable consequence all lithium batteries struggle with. Performance drops off at low/high temps. The way it’s mitigated is via internal heating/cooling or housing in a suitable place you have a fighting chance of maintaining that core temperature range most of the time. Direct outdoors will always be very very hard. If budget isn’t a factor the Tesla power wall 3 has some interesting specs!

Currently still unsupported by GE although possible…. We are not currently doing it until fully supported and out of beta testing

@@electrician247 Thanks I do feel like a beta tester with just the one

I’ve shown a similar design on the channel before Darren. Always double check on modecsoft electricalOM for circuit compliance but it’s in by miles. Not an issue. It’s also 5 core 🙌

What is the fault the growatt inverter shuts down with? PE by any chance? If so your neutral earth bond rely is not set on the aio. This needs correcting

The fault code was PE as you said then Growatt performed a firmware update and the fault code changed to AC F outrange. Thanks for the reply Mark 👍.

The ID buzz, nice! You need a compatible vehicle to grid charge point and vehicle. Not sure on the buzz but the hypervolt is not V2G compatible

@@electrician247 that sucks thought I mite be lucky with hypervolt lol, the van saying it let's you use 4000kwh to v2g that would be around £600 export to grid

Probably more on different tariffs especially in winter

There is no rules on this, just my opinion and methods. As discussed in the video I view it in the same way I would PME service heads outdoors. With consideration of the requirements with caravans and such. We need to remember the gateway in/out has no RCD protection on it. The earth electrode or in this case condudisc would help mitigate risk to a degree. But it’s avoidable risk. My question would be why use one? Other factors are to do with first responders and while enclosing batteries in steel seems like a very logical and prudent thing to do. In the worst circumstances it doesn’t burn away and by nature is conductive. Potentially making a bad situation worse. The heat is insane when these things go wrong. The tin sheets would melt and warp all over. You then have the explosive aspect. The videos are out there of garage doors being blown out. But crucially still attached to the building. Timber and GRP would still suffer with this but is more likely to hold together or snap. The steel shed are usually very thin sheets, riveted and screwed. My view is shards and sheets of sharp metal are an unnecessary risk to anyone coming to tackle a fire or get to the equipment and turn it off pre an explosion. It’s fair to say I often over think things, LFP battery issues are super rare, nil in the UK so far as I am aware. But if we have decided they should be outdoors I’ve approached it in a way I think mitigates risk and can be made to allow for the best longevity and performance of equipment outdoors. Others will see it differently and that’s just fine.

Only with older inverters that require 300mA in some cases

One of my 2 house RCDs trips in island mode, I experimented with 300mA and it no longer trips. I don’t think 300mA is permitted in a domestic setting so I need to look at replacing the whole consumer unit with RCBOs…

@@McOw123 ahh okay. I thought you meant the PV RCD in the gateway was operating. We have had that before. The tripping will likely be earth leakage inrush when the milli second drop out occurs. This is why we are limited to 9mA natural leakage on any RCD now. I would clamp meter the LN tails on the consumer unit set to record peak value. Turn the main switch off and back on. See what spike you get. Then it’s a case of finding the problem equipment or swapping the RCBOs which tbh would be my recommendation anyway.

@electrician247 Thanks for reply I do off grid installation we connect the earth bar and neutral bar together in first disboard and an earth rod then wire installation as TN-S also take earth neutral link out of back up generator.The batteries are lead acid opz and we use half shipping container, hence the question, to house them the fire risk is much reduced I can see your logic with lithium ion .

@@brianwoodruff4891 a shipping container is a different conversation to a tin shed. Lead acid might bring risks from gassing to worth covering suitable ventilation
