Read your meter at about 9AM and 4.30PM for the day/night split, you need to generate all your energy in the 9-4.30 slot. Have a look at my Solar carport thread https://aseannow.com/topic/1120934-how-about-a-solar-car-port-on-a-budget/ although the "on a budget" tag isn't really relevant now with the latest planned enhancements

This ^^^. Edge of Darkness is still superbly watchable and the Troubleshooters (UK series name with the MOGUL oil company) definitely worth a re-look.

Many modern hybrid inverters can run with or without battery, so you can start with no or a small pack and add later. Do beware of inverters which use proprietary packs (e.g. Huawei) where the OEM packs are silly money and no second-source is available. The only system component that I recommend you max out on initially is your inverter(s). If you need a system where two or more inverters are going to be required then I suggest you buy all of them at the start. There's no guarantee that you will be able to parallel more modern units with your existing ones when you decide you need more oomph.

Even using a contractor, you should expect to see payback in around 7-10 years. From then on, the energy you get is free! Panels are usually warrantied for 20 years to 80% rated capacity. LiFePO4 batteries are good for 6-10k cycles (>16 years) to 80%, treat them gently and they will last forever. Barring accidents your inverters should last as long as any other modern piece of electronics, many have 5-year warranties. As far as maintenance goes, it's really limited to cleaning your panels and any fan filters your inverters may have.

So long as we don't get a repeat of 2022!

Any indication of day/night usage split - To size your battery pack? Peak load - To size your inverter? Do you actually want to be off-grid or maintain a PEA supply for backup? Finger in the air: - 40-50 x 340W panels @ 2,500-3000 Baht each - say 150,000 Baht (that's 100m2 of panels!!) 30kWh battery pack - say 4kUSD (as a kit from China) so about 150,000 Baht 10kW hybrid inverter (2 x 5kW) - 90k Baht the pair. So, a ballpark 400k Baht for the kit, add 50-100% if you use a contractor to install.

Someone stood on a Lego or a UK power-plug!

Just blame autocorrect, it's a sitting dick!

The Forbidden Planet has been removed

More likely Icarus with the current weather!

Only into fresh underwear!

I would try the card in an ATM, if it does actually function you have pilot bank-employee error, if it doesn't then it's time to talk to your bank.

This ad. has been sanctioned by AN Management. I have two Growatt SPF 5000TL HVM-WPV-P inverters for sale as a pair. These units are new in their original packing and come with WiFi dongles and parallel-kits (hence selling as a pair). They were new in 2020 and have been in dry storage since. Do note that these are not the latest and greatest but would be ideal for someone who wants an off-grid system (with grid backup) or already has a system using these inverters which they wish to expand or have as spares. Please read up the spec. of these units to ensure they are suitable for your purposes. Manual and spec. spf_5000tl_hvmwpv.pdf These are part of the estate of a mate who died last year, his widow has asked me to get what I can for them, all proceeds will go to her. Offers by PM only please. Collect in northern BKK or I can ship at cost.

Another thought. What is the start-up voltage of your second MPPT input? Will one panel actually get it going?

You need to be very, very careful switching panels when it's light. DC is a very different animal to the AC most timers are designed to switch. I would be tempted to try it as you suggest and see how well it works, then add the blocking diode, then try actually disconnecting one array at a time.

2 x 150W in series = a Voc of 44.92V In parallel with your 600W Voc of 49.53V That's about a 10% difference in Voc. It will certainly work, just how much efficiency you lose is debatable. I'd be tempted to add a >20A Schottky diode in series with the 150W panels to avoid reverse-biasing them (which they really don't like). Is there really not room to put a 600W on both walls??

What are the parameters of your panels (post photos of the labels)? Vertical panels are certainly finding favour in the higher latitudes, but the sun rises so rapidly here I'm wondering just how much extra energy you would actually gain. Moved to the Alternative Energy forum.

If you are running strings in parallel to a single MPPT input your strings should have approximately the same Voc total (say within 10% although it's not a hard and fast rule). The strings come up to voltage very quickly when there is any light at all, there's just no power there (they will certainly make your eyes light up mind). Sketch out what you want to do (including the panel quantities and parameters) and post here, we should be able to determine just how well things will worth for you.

The dimmer may have a minimum wattage, but if not, I'd aim for running it at about 30% of its rated power.

I'm assuming you want to dim mains (220V) LEDs. Your first port of call should be the instructions for your LED lamps. Many modern lamps will actually work just fine with conventional dimmers but whether your particular lamps will work with your particular dimmers is still something of a lottery (it used to be a black-art). Ask the advice of the seller of both the lamps and the dimmers.

I never really worked out what the blokes on the see-saw were doing.

It's on a slow boat to from China.

Just under 25kWp

Current thought experiment. The 6 panels at the top are installed and working. The 6 at the bottom should be done and working this week. The additional 28 need some planning (how to support where the columns won't get hit). All good fun.
