This is what I built to monitor the battery level and solar charge rate. It shows battery level, solar charge voltage and amperage, controller temp, inverter temp and battery temp. In the pix, it is indicating 64.4 vdc at about 9 amps. This is off a 600 watt panel bank. I added an additional cooling fan on the controller with a thermostat set for 115* on, 105* off.
