I would like to add some more panels - directly connecting to the batteries.
Could there be any problem with a 605 Watt panel?
(Aiko A605-MAH72Mw COMET 1N 605 Watt, data see photo)
In summer I expect a production of more than 500 Watt (the max. input of the B300S).
But as far as I’ve read the battery itself will limit the input(?)
That’s right. The charge controller automatically limits the power consumption of the B300S to 200W (max. 10A). Please note that the voltage must not exceed 60V. This should not be the case with your panels. The current is automatically limited by the B300S to max. 10A.
Ok, fine, but you mean 500W (not 200W), yes?
Sorry…you’re right. It’s 500W. I confused it with the B300.
