Have the price really fallen that much since you bought in August last year? What is the difference between the SG03 and SG05?

That is a big system. What size of array and what brand of panels do you have?

Weight might be the limiting factor for my choice of battery. 130 kg up my 120 step narrow staircase just isn't possible.

5 panels less, so pretty much identical to the CBC price, but I certainly like the Deye battery pricing. 15 kWh for 64,500 baht is just eye-watering. I might go for 30 kWh. Sorry, just realized it is not a Deye brand battery. Google works in strange ways.

Thanks for your reply. Contract installed. I got a 200,000 baht quote from CBC for the following, but if Deye is a better brand and you know a contractor, please share. 5 kW inverter 5 kWh battery (extra batteries are 40k) 14 x 540 kW panels

Norway 🇳🇴 did the same tax "mistake".

20 kWh/day should cover 90% of my usage, which is almost all AC usage: 2,000 W aircon (2 × 9,0000 BTU) 500 W pool pump (4 hours/day) 50 W TV 150 W fridge 150 W LED lights + fan + wifi 200 W water pump (1/2 hour/day) Very intermittent low usage: 1,800 W vacuum cleaner 600 W toaster 800 W nespresso Is it straight forward and trouble free to add an extra inverter and battery on an existing system? If yes, then I could start out with: 5 kW inverter 20 kWh (4 × 5 kWh) battery 12,800 W panels What do you think? Last, but an important question. We do have the occasional power cut for an hour or two. Is it possible to set the inverter never to go below 20% battery, so as to keep the last 20% as an UPS function?

We are a group of 19 villas that run on a communal generator. The generator is way oversized, 60 kVA, and burns through 3,600 l of diesel ⛽️ every month.

American 🇺🇸 got a new president, according to Swedish TV.

Now that we have established that Vinny and this Oily fellow is the gold standard of EV knowledge, I want to come clean and confess I am in the process of installing solar power. I know it is a very dangerous and slippery slope, that over time could lead to an EV, but since I am paying 30 baht/kWh, it is a risk worth taking. At the moment I am using 12 litre of diesel daily to generate electricity, so the main problem is how to maintain my carbon footprint 👣 when switching to solar 😉.

Perfect, the 8.2 kWh number was exactly what I was looking for and it looks like that can easily happen 3 days in a row. Meaning even on extreme low solar days the panels still deliver approximately 1 hour of nominal rating. On the other end, looks like it is also possible to get 6 hours or almost 50 kWh on the 18th of August. Good stuff, thanks. The Inverter has 2 strings of 600 V, so I am considering 2×10 of the below panels, if I have the roof space.

Based on UWEB's link, the CBC 200,000 baht quote is about right. https://www.thaisolarsystem.com/product/1162/ชุด-hybrid-ongrid-deye-5k-1-phase-battery-5kwh-พร้อมติดตั้ง

Zero might be a bit on the low side. Crossy's all time low is 13.9 kWh from 11 kW of panels on a cloudy ⛅️ October in 2023. What was your all time daily low and at what size array?

Right, you basically curtail power generation on most normal days. I am not really concerned about sunny days, they will always produce more than needed. Crossy is getting 20 kWh out of his 23 kW panels on rainy days. Similar it looks like you are getting 8-10 kWh out of your 9.7 kW panels. Do you recall the lowest couple of days you have ever had?

But, but nobody wants EVs.... ssstwitter.com_1741758677974.mp4

I was looking through your charts to get an idea of the lowest power generation during rain and cloud covers. What is the lowest production you have seen over a 5 days period? You have a 8 kW inverter, right? 9,720 W panels? My point, was to figure out how much is gained by oversizing the solar array. I am considering a 5 kW inverter with 9,000 W of panels and 15 kWh of batteries. Reasonably or way off?

What happened from July 10-24th? Curtailment? You were traveling and the house was empty? Usually July are sunny days in ur area.

Plug&play will of course cost more than DIY, but based on your prices, the quote is a bit excessive. The 5 kWh battery pack alone is 40,000 baht and I was planning for a total of 15 kWh of batteries, so 280,000 baht in total. Is a brand name 5kW grid hybrid inverter really only 12,000 baht? I might need to shop around and get a second quote.

Is CBC a good choice for battery and Inverter? I got a quote: - 5 kw Inverter - 5 kWh battery - 14 x 500 W panels 200,000 baht including installation. Reasonable?

Nope, it is one of my seven sisters 😉. We are facing daunting future.

Good lesson, but a lot of the oranges 🍊 sold since 2023 have turned out to be lemons 🍋.

China is probably already building 100 similar ships 🚢 on their own.
