I'm 99% sure it's 2.4 x 1.2 m or thereabouts in a myriad of thicknesses and qualities ranging from "marine" to "shuttering". You really need to go and look at what they have and pick something suitable. @sometimewoodworker is your man.

I'll move this to The Pub I think.

Many moons ago I was working in the RN calibration lab, at Monks Park in darkest Wiltshire, calibrating AVOs. We had an AVO come in for cal. still in its "leather" case, slightly unusual but not unknown. Upon opening the case we found out why, inside was a kit of parts that had been, at one time, most of an AVO. It turned out that Jolly Jack Tar was servicing a radar antenna and had "accidentally" dropped his AVO off the mast. Contact with the rather unforgiving steel deck converted said unit into a kit. It was apparently less career-limiting to just send it for cal. than to report it damaged.

Just to confuse: - The MEA area (Bangkok) is 230V nominal. The PEA area (everywhere else) is 220V nominal. Both are supposed to be +-10%.

No worries, these things happen. It wouldn't be the first time someone has been misled by faulty test gear (this t-shirt I have). But 238V is still rather high (220V +8%) so it's worth keeping an eye on it a low load times (middle of the night), just in case it gets excessive.

I before e ???? But the main reason is that we in the west, are really over-cautious on the "kill-everything remotely harmful" front, so when something remotely-harmful comes along we get sick. Meanwhile, after a few years in the far east / tropics we become used to the local bacteria and they don't affect us, whilst the poor tourists spend their holiday in the bathroom** ** Useful fact, I found the bathrooms in the Museum Inn, Bangalore had an ideal design. You could sit on the pan and throw-up in the sink without moving. It would seem that India has rather different bugs to those found in Thailand

A couple of posts removed. Do I really (really) need to say why??

On recommendation from another forum, I bought one of these $70 chaps. https://www.aliexpress.com/item/1005003755306962.html Believe it or not this little guy is a 3kW (yes you read that right) power supply cum battery charger. Got a 5A charger? Pffft! This chap will bang out up to 60A (assuming of course your pack can handle that charge rate). Available with various pre-programmed voltages (all around a nominal 48V although I understand there's a 24V version) or set it yourself via the CANBUS interface up to 60V. Built like the proverbial brick outhouse these are designed for long service, not new but for the $$$ buy two.

Yeah, those really tiny ants like electric fields for some reason, and crushed ones are a pretty good insulator when they get inside switches.

The world's single most fattening food!

What does the cable feed? If the load is less than about 8A then leave the breaker as it is, no harm.

If correctly installed with no leaks your A/C should work for years without needing a top-up. Order a professional cleaning and service to include a refrigerant check. If a top-up is required, they will tell you and bill for the refrigerant needed.

Nominally 450V DC which places them firmly in the "not really DIY" area. Huawei 5kWh unit 162,000 Baht! https://www.solartech-center.com/product/1006/huawei-battery-powermodule-luna2000-5k By contrast an off-brand 48V, 5kWh pack is around 60,000 Baht and if you DIY around half that.

Some more off-topic trolling posts and replies have been removed.

I'd certainly invest in a cheap DMM (multimeter) just to double check.

If it's reasonably firm then geotextile followed by laterite or gravel would probably be the cheapest way and would retain the rural grass-up-the-middle feeling. Light traffic only of course. The geotextile stops the gravel vanishing into the mire. Top up the gravel as required.

We have two Thai-style chihuahuas, rather larger than we in the west imagine chis are, super little (ish) barkers. Excellent early warning system that sets off our real guards. Geese!!

A trolling attempt to derail the thread along with the sensible reply has been removed. If you don't like dogs, please feel free not to post.

The inverter itself should provide ground fault protection on its output side, if anything ourSofar is a little too enthusiastic. You would normally run in "grid-assist" mode rather than fully off grid, so if there's no sunshine and your batteries are dead the inverter will feed through from the grid to your loads. All things being equal you may never notice which supply you're on.

Flame removed! Let's play nicely shall we?
