This thread is nothing without pho ... Actually, I think not, way too scary

It is oft said that if it flies, floats or f**ks - Rent! Meanwhile, it will be our 21st wedding anniversary in November, still love her to bits.

Yup, dejá-vu is alive and well.

Bingo!! The setting is called "Zero export to load", like that you don't actually need the external CT as the inverter will use its own internal one. Using an external CT won't hurt and the inverter comes with one anyway so it's just more wiring. You might consider running heavy stuff like water heaters off the grid to reduce strain on your inverter and batteries.

Do it like this. "Home Loads" are not battery backed up (but they do use solar energy if the grid is up). 'Load" is battery backed up. You can put the AVR at A or B. I would prefer A unless you know it's going to behave having a grid-sync inverter on its output. Ignore the diesel if you don't have one.

Doing it as drawn will give you ZERO battery backup if the grid is down. Grid off = House off. Is that what you require?

Looks pretty OK to me. Fuses, breakers, surge suppression, labelled terminals, ATS - Check! 🙂

I do the boxes last otherwise the ruddy things keep moving (accidentally selected), but it doesn't really matter. Personal preference.

You will need 4-wire each way I'm afraid, that's assuming you're going hybrid solar. You could still put the panels on the garage and run solar DC to inverters in the house. That might prove cheaper. Do you want batteries (even LiFePO4) in your living area? How much solar do you anticipate? You may get away with smaller than 25mm2 cables unless volt-drop becomes an issue. Best way is to sketch what you would like to do and cost up the cable runs.

The "Snakes of Isaan" Facebore group think he's a Golden.

Yeah, I thought he was a Golden too, mildly venomous but rear-fanged so of no danger unless you are a rat etc.

Sorry, fetching my (sheepskin) coat

Out of the plane? That's a bit much even for a crazed Iranian

No candles other than the orange religious ones, but we do have some oil lamps recovered from MiL's home when she died a few years back, they've been cleaned and polished and now live in the nick-naks cabinet. I'm sure they would actually work Madam sold the plot which was in a good location, and bought a similar sized plot a bit further from the road. She had enough $$$ left over to build a nice steel and Shera family home for remaining family. Smart cookie that lady (she married me) 🙂 We already had the genset of course and it seemed a waste not to use it. In reality it gets run once a month or so for testing and we push the energy into the batteries, I doubt we will ever actually need it in anger (famous last words?).

Our system is like this highly-simplified diagram. The breaker between the inverter and home loads is usually off (turn it on if we need to charge the batteries from the grid). Home loads are just our on-demand water heaters, keeps the meter moving in the right direction and limits strain on the inverters and batteries. If/when we get an electronic meter I'll shift the heaters to the load side and stuff PEA. If we lose the inverters then the transfer switch flips over and, after about a second, we get grid supply to the loads.

Ouch! If the inverter never goes into export, then I suspect things will be just fine as it's seen as just another load, but ... I'm pretty sure the Deye can drive an external transfer switch, so you could run the AVR to that, and in the event of low battery the external ATS flips over and you get regulated power. I would check with your solar installer what he recommends, then you have someone to blame if it all goes pear-shaped

Earth and neutral are certainly linked somewhere in the installation. In a condo it's likely that you have a TNC-S (or possibly TNS in an older place). Have a look here https://en.wikipedia.org/wiki/Earthing_system If you don't actually see a link then it's going to be elsewhere. If you measure 220-230V between a live and the earth and something close to zero between neutral and earth you're likely good to go. In our old condo all the A/C units were supplied from live and earth!!! They worked just fine although I did move the connections to the right place 🙂

Good question, and one I thought about in the past. In the end we decided not to and our AVR is currently disconnected. Just how low is "somewhat low", most hybrids are perfectly happy down to 185V or so at which point they disconnect from the grid and continue powering the loads from solar/batteries. My main worry is that the AVR isn't designed with this mode in mind and the control system could become confused and do weird things. Note that I didn't actually test this so what actually happens is unknown and is very likely variable with the type and manufacturer of the AVR. If your supply is always very low you could consider a fixed boost auto-transformer, basically a manual voltage regulator, lower cost than an AVR and no control system to become upset. Personally, I wouldn't bother doing anything unless it becomes an actual issue.

Try running the unit on "dry" before you start exercise to remove existing moisture before running it on "cool". Or try the other way round. Run with the fan on high, not auto.

The shade hedge is a bit thin at present having had a haircut, but not doing too bad. I may add some ventilation fans to move some air around.
