Yeah, we are doing at least 50% better than that from similar used golf-cart cells. How is the cell balance?

Our 10.1kWP (all poly panels) peaks out at around 8.5kW at the inverter output. That same day generated 41.7kWh. I'm definitely not unhappy, the panels are not perfectly angled (on the car port roof).

Yeah ^^^, for a dryer that's likely running for long periods I'd go 6mm2. At 6.6kW are we looking at an industrial dryer?

If you've not updated for a while it will expire as not supported, time to update. You can update via the Play Store, it should appear in your list of available updates (I'm assuming Android here, one also assumes iOS would be similar). If the update does go pear-shaped you can still access via your browser at https://www.scbeasy.com/

Wikipedia has an explanation of all the various flavours of earthing systems https://en.wikipedia.org/wiki/Earthing_system To expand on STWW's post Thailand is TNC-S with MEN or PME (for our purposes the same thing). You MUST wire your incoming supply as in this diagram if you want to pass a PEA/MEA inspection. Note the routing of the incoming neutral. Drawing is from this handy PEA document which you can show your contractor Groundwire Mk2 book-Manual.pdf Once you have a permanent supply (4.x Baht per unit) you can do pretty much what you like, so if you really love TT then go for it.

Reagan and Carter are on the case ...

Yeah, I agree, but if he gets the go from the landlady it's easy enough to do. It's not an MEA/PEA meter so no legal issues (other than with the landlady).

It will look something like this:-

If the meter is still functional it's easy enough to put it back in circuit. Do you have a multimeter or neon-screwdriver? Check which end of "your" breaker is the outgoing side (turns off with the breaker off). With it off remove the wires from that end and insert them into the free terminals on the meter. Is the cover available? It will tell you which side is L and which is N. Connect the two wires that go nowhere to the vacated terminals on the breaker (You may need to use longer wires). Turn on. Run your shower to check the meter actually works. Read the meter. QED Or just ask the landlady to get it put back in circuit and agree a price per unit for energy used.

According to the Tech Spec page on MG Thailand it has a 50kWh Li-ion pack.

With the 250k subsidy the MG-ZS is looking very tempting! The version with the whizz-bang extras just scrapes over the 1MB line.

Amorn are usually a good source for remotes of all flavours (original and "pattern").

Do you have to pay for the "open" sign as it's portable? Local plod tried (half heartedly, he's not stupid and he knows my wife) to charge us for the English "29 Palms" (I'm a Robert Plant fan) on our house name sign.

Ouch!! Before you get the man in, turn it all off and try moving the variac by hand. Ours threw a wobbler and stopped regulating, i never really found out what had gone wrong but removing the motor and putting it back fixed the beast.

There most definitely is external control in some GTIs for certain markets, Oz being one of them ???? If your inverter has WiFi then it most likely has the facility for external control, whether that control is enabled or exercised by those in control ....

A properly configured hybrid will only import grid energy when there is low sunshine and the batteries are depleted. There is nothing to stop you configuring it to never import - all that happens is your lights go out if there's not enough solar and your batteries are depleted. The whole point of running hybrid (of either on or off grid flavour) is to ensure you always have power, they are inherently a UPS. I'm not really sure what the confusion here is to be honest. Maybe start by forgetting about the batteries and consider how a pure grid-tie system works, then do the same with it set to "no export". Once that's clear you can add an ESS into the fray.

Because the systems in question are grid-tie (no batteries). If the grid can't take the generated energy the authority shut down export. Hence my friends adding batteries to store that energy that would have been exported if permitted.

Yeah ^^^, with an AVR which will provide its own low-voltage shut off anyway, why bother with our orange friend and its associated contactor?

No, it just means the inverter is exactly balancing its output against local consumption, so grid power is zero. If there's no solar the inverter is quite happily importing for local usage and battery charging if you have it configured like that.

By far the best people to contact would be VFS who handle all PP issuance in Thailand. Failing that, plenty of agents who will do all the donkey work for you.

It's definitely "horses for courses". The grid can only absorb so much power, if there's more available than is being used then they either have to shut down the exporting systems, or store the excess energy. Of course one option is rather cheaper for the energy companies than the other. If my system was being regularly curtailed I would certainly be looking at storing (or using) the available excess. How viable that would be based upon cost-benefit would depend upon multiple factors. Here in sunny Thailand I'm quite happy to spend the $$$ which I didn't spend on a "professional" installation (which would allow me to legally export/re-import my excess) on an ESS which will let me keep that energy within the boundaries of my property and then let me use it later. I know that one day I'll end up with an electronic meter at which point the unofficial net-metering will end, so I aim at being ready. As a bonus I get UPS functionality that keeps everything but the big pumps and water heaters alive when a cement truck takes out a line of power poles.
