I'm looking for a backup charge controller. I have SolarWorld SW270 watt panels (~38v @8amps) and I'm looking for a small 20 or 30 amp MPPT charge controller. I don't need anything fancy, just something that can charge a 12 volt (or maybe up to 48 volt) battery bank.
I see a lot of the cheaper Chinese controllers but am always wary about them. Any suggestions? Any opinions on the Renogy products? I already have my primary outback equipment, I'm just looking for a secondary controller as a backup.
