I think I have 3 options. 1: Connect one panel to each of the 300AC aviation port cable, 2: Connect both panels in series to one of the 300AC inputs (12A 88V), 3: Connect one panel to the 300AC input and one to the 300B but thats perhaps only if the 300B is used on its own?
So is 1 or 2 the better setup for charging?
Taht’s not a lot of panel for your system.
Connect one panel to each of the 300AC aviation port is thh best option.
this is the second best option.
This only if all the other MPPT inputs are alredy full.
- you add one panel per input
if you want to add more panels and all inputs are full start putting panels in series.
If the max OCV /VOC is reached and you still want to add more panels add them in parallel
Thanks lambda - that is how I have set them up by default. My usage is not great (one small fridge) and the two panels charge up the nights usage in only a few hours and allow for a few low light days. I wanted a system that I could expand, additional batteries and panels as my usage grows in the future.
Hello,
take google and search for overpaneling…
You will find very interesting informations to tune your solar earning…especially wenn the sky i cloudy or the Sun stands not so high.
