I plan to install on my bimini 2 Gioco solar panels 207W with dedicated Victron controllers. I have 4x85Ah Exide battery bank (12v). Is it enough/safe to put a 75/15 controller or should I go higher? I’m afraid I would be on the edge with it but just to make sure if it’s necessary to go higher. Also, would such solar array be enough to fully charge my battery bank (I’m sailing in Med). Thanks for your reply. - Djoka
Considering your Gioco flexible solar panels are 207W each, I’d consider getting a larger controller, perhaps the Victron 100/20 as the 75/15 max wattage is very close to the 207W rating of your solar panels.
