I have four 12V 100 watt panels in series working just fine. I have a potential deal to get two 24V 200 watt new panels for cheap. Specs for both :
CURRENT panels
Maximum Power: 100
Open-Circuit Voltage (Voc): 21.6
Short-Circuit Current (Isc): 6.5
Optimum Operating Voltage (Vmp): 18
Optimum Operating Current (Imp): 5.56
Maximum Series Fuse Rating: 15
NEW panels
Maximum Power(Pmax): 200
Open Circuit Voltage(Voc): 45.4
Short Circuit Current(Isc): 5.83
Maximum Power Voltage(Vmp): 37.6
Maximum Power Current(Imp): 5.32
Maximum Series Fuse Rating: 15
All attached to a Victron 100/50. I am running a 12V battery (may shift to 24V later), so the system will top out at 700 watts per manual. That's fine by me as the current setup tops out at about 350 watts, so over-paneling may work.
Based on the specs, it looks efficient to put the two 200 watt panels in series and parallel them to the four 100 watt panels already in series. This should run them all at the appropriate voltages. Can you fine folks please confirm?
