I am happy to write after six months that there are a few new technical upgrades and fixes in our cave/tent living community.
The last upgrade was on 2024.11.05:
Solar power system upgrade/repair in the storage cave (2024.11.05)
Currently we have two 12 Volt batteries connected together.
We have new solar panels too. Some of them are not installed yet. Not all of them are the usual 100 Watt panels. Currently we have more powerful solar panels too.
For example a few 460 Watts solar panels too.
The inverter is still the same as before (Islanders Series Islander-IXS 1000) (1000 Watts).
The refrigerator/freezer in the storage cave still does not work continuously, but at least now we can charge multiple smartphones, power banks, laptops, even in the night.
By the way, one of our engineers said that someone connected a 12 Volt <> 230 Volt converter and a 230 Volt <> 12 Volt converter together.
This was obviously unnecessary, and resulted in electric power and efficiency loss.
Of course this has been fixed by removing the unnecessary voltage converter.
