Yeah, I leave it split as Watts and Hours simply to help people understand the units, it's already a terrible over-simplification anyway. ????

Now, about that 30 billion Baht owed to BTSC thus far ...

Let's continue over in the new thread.

Sounds about the right ballpark.

Yeah @Encid I'm seeing that price too ???? Must be a local offer.

You may have to show both to the check-in staff when you leave (to show you have right of entry to the UK and/or you've not overstayed in Thailand). Do NOT under any circumstances show both passports to immigration officers at either end. Dual citizenship causes their brains to explode!

"Here son, be the front man for this great business". "Ah, sorry, it's all gone horribly wrong, you're now the fall guy!"

Yup, hence the need for investigations. It should (yeah, I know) all be documented somewhere, however the evidence is likely already going through the shredder.

Dear BiB. Your next task is to locate the architect who specified the less than fireproof insulation and the contractor who installed it! It's no excuse but the owner could have been given poor advice in order to keep costs down.

For the MCB rating I'd go around 20% over your maximum expected current. You want it to trip if there's a major issue (short) but not trip under normal operation.

With the propensity of Thai rich-kids to flee, bail should be denied.

Meanwhile in the UK the police concentrated on taking out the terrorists.

We have 10mm2 to connect the suppressors to ground, and 6mm2 on the other side, it's only short lengths so that's big enough.

Also, if you need lots of really hot water then don't forget gas water heaters. They really blast out the heat and they're not horribly expensive. Do beware of installation issues with exhaust gasses!!

We have a local tailor who works out of his front room, Madam gets material and he makes work shirts and slacks. Since my wife controls the colours I have a full set of the "correct" colour for each workday ???? My lady also gets shorts from a market stall somewhere brand "Super Jumbo" they're actually too big for me, socks and tightie-whities are stretchy so no real issue. My main problem is shoes, as a UK size 12 dress shoes are unobtainium, at least at prices I'm prepared to pay. I order site boots from the UK (company pays).

Yup ^^^. Do get the correct crimp tool for the MC-4 connectors, if you're doing more than a few you really can't just squidge them up with the pliers. We did invest in "solar" cables, purely because they are supposedly UV stable and more resistant to attack from the local wildlife. But the regular stuff works just fine.

Yeah, I've noted many times that it's best to get all your prospective inverters at once.

Sort of, spreading your panels like that will enable you to start generating earlier and finish later so extending your production day but your peak rate (around mid-day) will be lower because 60% of your panels are pointing the "wrong" way. Thing is that "6 hours" doesn't mean your panels generate rated power for 6 hours it's just a way of getting an overall per day production without complex maths. Our panels are producing power at 6.30AM and they finally give up at around 6PM, but sure as heck they're going nowhere near even 10% of rated power at those times.

@Encid I don't think you are a million miles off there. Like I said there are masses of variables, direction, angle, shading and of course the weather.

For a very finger-in-the-air guesstimate (there are masses of variables):- Panel rating x 0.8 x 5 (80% of panel rating over 5 hours) Some days will be far better, some far worse.

Not really, if you have grid power just arrange the wiring to supply the heaters from the grid. Otherwise add inverters, the Growatt 5kW units will surge to 10kW so a couple of those in parallel would do the trick, you may also want to add a shower priority switch, whichever heater goes on first gets the supply, the other has to wait until number one is finished.

OK, let's take the easy one first. The second unit (with the red handle) is clearly marked + and - on the little diagram, it doesn't seem to be line/load marked. OK for battery. The Tomzn one also has + and - markings but they appear to differ at the top and bottom of the little drawing. Need to investigate just what this means.

Yup, no problem there ????

Yeah, that would work. Your DC surge suppressors go between the panel MCB and the inverter (close to the inverter, it's this you want to protect), if you have very long cables between the panels and inverter it might be wise to double up on the suppressors at the panel end of the run too, probably not needed but ... There's no need to suppress the battery lines.
