I currently have the Renogy 20A MPPT CC and (2) 100W 12V Renogy panels on my van. I have room for a third 100W 12V panel and believe my current Rover 20A CC is capable of handling it. The panels are wired in series. The battery is a single 12V 100AH LiFePO4 battery.
My main question is regarding going over max watts (last line of this post). Thanks to all who read

My main question is regarding going over max watts (last line of this post). Thanks to all who read
Panel specs:
- 100 W, 12V
- Short-Circuit Current (Isc): 5.21A
- Open-Circuit Voltage (Voc): 24.3V
CC specs:
- Max. PV Input Power: 12V/260W, 24V/520W
- Max. Solar Input Voltage: 100V
- Max input current = ???? not sure
If I'm doing my math right:
- Input current to the CC should still only be 5.21A max, which is the same as it is now.
- Input voltage will be 72.9V max, well under the 100V limit
- Input wattage could be as high as 300W, which is over the 260W limit, but I don't think my current 200W have ever produced more than 150W. Which implies that the potential 300W will never produce more than 225W, which is under the 260W limit. If it did go over the 260W limit, would that damage the CC or simply not capture all the production?
