Our place was Fraser Towers in PJ. We didn't actually have a balcony ("too high"), only lower floors had actual balconies so our usable space was bigger ???? The "best" thing about Fraser was the cooled pool, kept the locals out (too cold) and was great after toasting in the sauna for the Scandinavian feeling!

Our place in KL had a separate "mini-balcony" for the A/C outdoor units and clothes drying rack, it wasn't visible from outside the building or from other units (except from their own A/C balcony). See the circled "notch" in the building. Clever eh? Our condo here had the units mounted above the balcony doors, not ideal but at least they didn't take up the (minimal) balcony space.

Wikipedia has a good description of the various earthing schemes in use around the world. https://en.wikipedia.org/wiki/Earthing_system Thailand is 3-phase, 4-wire, TNC-S with MEN (multiple earthed neutral) or PME (protective multiple earthing) in UK speak. Generally, the neutral is held down near ground by the multiple grounding points (your and everyone else's local rod plus a rod at every third power pole). Problems can occur when there has been "work" done to your meter and the person has managed to swap L and N on the outgoing side. There was a thread a while back where a member noticed his kitchen floor above the earth rod was getting warm. This turned out to be a reversed supply! TNC-S with MEN is actually very safe (the Aussies use it and they have one of the safest electrical systems on the planet), but things can go awry when inexperienced people mess with it. Back on-topic, there's nothing to stop you using 2-pole MCBs or RCBOs, but, just like the UK, it's not really necessary.

Definitely keep it above ground if it's going to be bolted. Cinch it all up then coat the whole lot with spray-galvanising or a couple of coats of acrylic paint.

Your existing UPS probably just needs batteries, usually readily available sealed lead-acid. The Voltronic unit is effectively a hybrid solar inverter with batteries in a UPS shaped box. Nice simple solution in one box. Nothing really comparable available locally, you'd be looking at a small hybrid inverter, battery pack and solar panel(s).

Don't. How is the cable attached to the rod? Generally, the connection should remain above ground or be in an earth pit to avoid corrosion reducing the effectiveness of your earth.

Please can you post a scan of your current bill and one you are comparing with? The only recent changes have been Ft (and an Ft rebate for low users). If "other costs" are doubling you may have a billing issue.

I don't know if the relief will be short lived, but our daily usage is heading back down towards our normal 30kWh after peaking at double that. As noted in an earlier post, our habits haven't altered, just the weather.

The brown thing top left is a Chang knife switch which looks like it's being used as a solar isolator, top right looks like an AC rated MCB, the + - markings confuse me somewhat but I suspect it's being used to connect to the mains. Bottom device looks like an energy meter to check your production. I also note a Schuko type plug rammed into a Thai outlet, so no earth continuity which with a transformerless inverter like that one could lead to a shock hazard from the panel connections.

PEA and Solar how low can you go?
Crossy replied to MJCM's topic in Alternative/Renewable Energy Forum
For a bit of a reality check your 1kW system will generate about 3.6kWh of energy per day (dependent upon weather of course). Definitely worth having of course. -

Generally yes, most inverters allow a degree of over-panelling provided you never exceed the maximum input voltage (Voc of your panels). A 600W/VA inverter would likely be OK with 700W or so of panels. -
The UK isn't known for being cheap. A 1hr 15mins flight for 150 squid (6,300 Baht) per person would seem the right ball-park. https://www.wingly.io/en/flights/2011948
