I am not allowed anymore export i.e. I have 2 x 3.66 inverters ( one for pv other on Tesla battery ). Apparently that's my limit. I should mention I'm not particularly worried about export - I want to keep as much as I generate as possible. They did inform me that in my area for future installs they may have to limit it to 3.66Kw. The example she gave was if all my immediate neighbours all suddenly decided to have PV and export they would have to reduce export due to infrastructure limitations. DNO's are under lots of pressure. Government says 'go green' yet the DNO has to manage the variable export that could occur ( bet they have fun in summer )

You could put as much as you like in then as the only AC coupled stuff would be your existing equipment. ?.

Expand please keep us (me) updated on this as, due to various reasons I won't go in to here, my Powerwall install has been cancelled and so before I go and find another installer for a Powerwall I thought I'd investigate other battery options and will be interested in your other battery experiences. interesting that you're going Solar Edge battery and not the Solarwatt that @Nickfromwales is suggesting. I thought Solarwatt had more experience in the battery segment?

I email loads of companies on anything I am interested in. No reply, or a weak reply, or just a "brochure attached " means I bin them. If they can survive 10 emails of questions then it shows me they want my business and $$$$$. I would add another Tesla battery but aren't allowed . With SE I can do what the (expletive deleted) I want. 1

It is OK fitting all this extra kit, but it has to power things internally, so you need to know the Who, What, Where and When.

I believe you are 3 phase - so you could in theory have 3 of the bad boys. SolarEdge ( as I said may for install ) so that's not too bad. No idea about SE - but @Nickfromwales is a plumber/tiler - not sure his expertise expands into battery storage .?

Expand That will probably only give you a general overview. It would be nice to know that if you have a load of say 300W, and your PV/Battery combo has 500W generation, and your water needs 1 kWh (see, I have changed units, for a reason), would you know how your system is performing?

Expand Not sure how you are going to measure "performance " ? My view of performance will be how small the electric bill is. I *could* in theory add HA to water tank ( even every electrical appliance and socket ) so I could see exactly what is using how much. But - I'm sure exactly how useful all that info would be.

But - I'm sure exactly how useful all that info would be. Expand Well only to the heavy loads, i.e. water heating, car charging, oven and hob useage. It is very useful. How I get such a low usage and lots of time without any usage. Times without any usage are, in your case, charging times.

SW are using the same cell tech as is rolling out in the new BMW EV’s. SolarWatt are 100% owned by the brother and sister who own 80% of BMW. Pretty robust in terms of warranty longevity imho.

Also found out that my DHW was heating up, cooling down, heating up again, cooling down, and quite often heating up again. So limited thee time that the heating starts in relationship to the time I use it. Going to fine tune that a bit more this year as I think I can probably save another kWh.day-1. Also, being away a lot this winter, I have found the best setting for my storage heaters, then put a 50p piece on them to easily adjust the input side. That is a job that is crying out to be automated. Everything else is now such low energy, except the washing machine, that it is not worth worrying about i.e. I don't care if I leave a 3 W LED on, or my 8 W laptop download from bittorrent all night.

AliG Posted February 11, 2022 Posted February 11, 2022 I’m off to Disneyworld tomorrow. Surely it’s basically free if I turn the heating off while I’m away.

Better off leaving it idle at a setback temp perhaps vs off?

Expand I deliberately leave a desktop PC, NAS, several Raspberry Pi's and a 300W dehumidifier on 24/7 to help maintain 15° in my electronics workshop. I wish there were a few more loads I could move over there from the house as the remainder of the heating demand is currently made-up with a 2kW digitally controlled panel heater. The more useful work I can get done for the same power input the better during the heating season. Pity it's too far away from the kitchen.
