Hello!
I am new here so please forgive me if my question is silly ^^
We have thought situation with electricity in Ukraine, so I decided to install as many solar panels as possible to avoid blackouts.
As for now, I have 1 string with TrinaSolar 540W mono and planning to install 12 more panels,
but I can not find the exact model, so I will go with TrinaSolar 550W mono.
Totaly I will have 15 panels with 8.3kWt power )
MPPT calculator(xlsx file) shows me that 3 strings for 5 panels will work for MPPT 250/100, but with some warnings (more than 30% oversized PV generator) it is most overfull MPPT in a calculator.
So can you advise,
1) can I use MPPT 250/100 or EasySolar-II 48/5000/70-50 MPPT 250/100
it looks like they have the same tech specs MPPT....
2) or do I need to use MPPT RS 450/100 for my case
3) or I need to purchase an additional 5 panels (to have 20 in total),
re-design into 2 parts 2*5 and separate 2*5
and go with 2 MPPT 250/85
All this will be connected to 48V 10kWt battery and I'm going to purchase Victron Multiplus II 48V - 5000VA for the inverter
Thank you beforehand for advices.
