A dilemma,
In May 2021 I bought a solar installation with 2x 260Ah lithium batteries, 2 Must 5.5 kW hybrid inverters and 12 solar panels with an average output of 500W each.
From one moment to the next, the 2 inverters refuse to work, it looks like a software error, but that is irrelevant when considering what to do.
The supplier gives me the option of having them repaired for 4000 Thb each, the purchase price at the time was 24000 Thb each.
My average consumption before was 2500 Thb/month in monetary terms.
Today I can buy a new inverter with a capacity of 11 kW for 22000 Thb.
Now I ask myself, what is the best solution, have both inverters repaired, 2x4000 Thb + shipping, so more than 10000 Thb, then I will have the same ones back, but the question remains, how long they will work, 2. buy the new inverter at a price of 22000 Thb, or 3. Just go back on the public grid for 2500 thb/month.
I know that there are some good solar cell users out there, and that is what I like to know, what you will do in my situation.
