I have a 12v off-grid system with 6 ground-mounted 135w 12 yr. old solar panels, 8 6v 220Ah batteries with a few years left in them, an Outback Flexmax 80 controller, and a MagnaSine 2812 inverter. I'm thinking of replacing the solar panels with 4 300+w panels (which would just fit my ground mount) for a 50% increase in charging. I understand that my controller would have to be replaced unless I change my system to 24 or 48v which seems like a good idea. Should I do this and will I have to replace my inverter? I'm doing this so I can cut back on the amount of time I have to run a generator in winter.
