Solar Charger Controller 20amp 12/24v DC input

Solar Charger Controller 20amp 12/24v DC input, are specified by both amperage and voltage. You will need one that can support the voltage of your solar panel array, and then output to the battery bank’s voltage (usually 12, 24 or 48VDC). Next, you’ll want to make sure the solar charge controller has enough capacity to handle the current (in amps) from your solar panel array. Take the wattage of your solar panels and divide it by the battery bank’s voltage to get a rough estimate of how many amps the controller needs.
