I have a greenhouse. I'd like to use solar panels, a 100/50 SmartSolar controller and batteries to run fans in the summer and circulate air. In the winter, I do not use the fans, but I'd like to run 12v from the panels to simple 12v heaters (200w) in water tanks in the greenhouse. I do not care about running the heaters at night, or on cloudy days. Would it damage the SmartSolar controller if I ran it in the winter with batteries disconnected? Power would go directly from the SmartSolar controller to the 12v heating coils in the water tanks when the sun is shining and be inactive when it is not. I have three 200w panels that are 12v.
