If you find that your panel is draining your battery at night then you need to put one of these on the positive MC4 connector of your panel. Max rating 20A so if you have a larger array you will need to put in Blocking Diodes on each chain to ensure no more than 20A can go from the panel through the Diode (or it will burn out).
