Considering used solar panels for our RV, and trying to see what MPPT SCC would work best with them.
I have an SOK 12v LFP battery bank, currently charged by a Victron Multiplus and monitored with a BMV-712.
There is room for four panels with little to no shading issues (flat mounting), but will likely install one series pair now and the other later.
Polycrystalline STC rated at 260w
Peak Efficiency 15.76%
Number of Cells 60
Imp 8.5A
Vmp 30.7V
Isc 9.01A
Voc 37.8V
NOCT 45.7°C
Victron doesn't offer a cost effective 100v input 40a SCC which it seems would be best for each pair. (520w / 13.6v = 38.2a)
Since they will be flat mounted could a couple of 100/30 Victron SCC's be overpaneled to cover a potential 520w?
Is 75.6v (Voc x2) high enough to give good performance on a 100v max input SCC?
Other SCC's I've considered are Rich Solar and Epever 40a, but neither have Victron's nice interface.
Whatever SCC I end up with I want to be able to plug in specific charging values to make sure they place nice with my current setup.
All advice appreciated.
