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?

Yes, pressing Test should turn everything off ???? You could try turning off the breakers for the outside kit and see if that makes any difference when it rains. Does the Safe-T-Cut trip out again if you reset it? Did you get a price for the Huawei battery packs? A couple of other members are looking for them and the $$$ being asked is frightening. Sadly, being high-voltage battery packs 3rd party units are like rocking-horse droppings ????

OK firstly, your new Safe-T-Cut DOES have a Test button ???? The big yellow thing with a T on it ???? My worry was that Safe-T-Cut do make units with no RCBO functionality, but you're good to go. Did your solar installer leave you with any form of diagram? I'm assuming your Huawei is running grid-tie with the EPS output running the kitchen to keep the juice on when the grid is down. When does the Safe-T-cut trip, any specific times (rain?), do you have outside lighting or outlets that may have let the damp in? Any upgrade would be to individual Schneider RCBOs for the "risky" circuits (water heaters, outdoor lighting and outlets etc.) possibly leaving less risky circuits (indoor lighting) unprotected. If something untoward happened only that circuit would go off.

Replace the fuel cell system with a battery and you have something cool and workable. BUT There are issues in most jurisdictions with not having a physical connection between the controls and the steering and braking systems. Officer;- "What caused the accident?" Driver:- "I had a BSOD at 70mph in the fast lane of the M25".

There is no reason that you can't switch languages whilst typing so you can get a ฿ in with your English.

There's also SCB Connect on Line, but chatting gets you a bot, no idea how useful it would be to our OP.

This worries me somewhat. Please can you post a photo of the new device? With no test button it likely doesn't have earth-leakage protection and if that's the case and it is still tripping well - Houston, we have a problem. From your description it's very difficult to tell what's really going on but it sounds like a proper electrical survey is in order to find out where we are starting from. Can you post a few photos of the kit, including your solar please?

Keep a written log with dates and times. You can throw this at PEA as evidence, but make sure you include weekdays too. They may be able to simply swap you to a "better" phase, a simple and quick job, do try to work with them rather than against them.

It's certainly rather higher than I'd like. I'd log it several times a day and overnight, during the week too. Being a sad git, I (ok our data logger) log our voltage and current every 60 seconds 24/7/365. If it stays constantly over 220V +10% I'd talk to your local PEA. It's possible they are trying to compensate for an overloaded transformer during the day / week which results in excessive voltage at night / weekends. Many of us would be grateful for some of your extra volts
