System to help rural Cambodia

capitanojuliano

Perhaps you may be able to help me.

I am building a system to provide 12 volt power supply in remote areas of Cambodia, these places are off the grid completely. They use kerosene lamps for lights which is a fire hazard. Also that light is poor for the developing eye sight of children. Anyway enough of explaining my motive.

The question is that i am building my system around the SBC 7120 controller

12 Volts with 20Amp maximum

Question: What is the maximum panel wattage I can run through this controller?

My mounting device will support the weight of 3 X 200 watt panel’s maximum; so nothing bigger than that. However will the controller manage that much panel output?
