Hello everyone,
I have 17 solar panels, 9 of them running 3s and 3p, the other 8 are 4s and 2p
total voltage is140v and 146v respectively
real world measurement just around 115v - 125v
since these # are less than 150v max that many cheap charger can support and safe to the touch if accident happened
wondering why there're many systems here with 400v, 500v + ?
what're the pros and cons ?
as far I can see, it's very dangerous and cost a lot
so what give ppl ?
understandable if the system is huge, like many hundreds panel or more
good day all,
