Sunsei SE-500 Solar Battery Charger FAQ's

Do I need a charge controller with the Sunsei SE-500 Solar Battery Charger?

Generally, a charge controller is not required for the SolarCharger Sunsei SE-500 because it is not powerful enough to overcharge your battery. However, a charge controller may be required for lower capacity batteries. In general a battery with 150 AHr capacity cannot be overcharged with the Sunsei SE-500. Connecting multiple Sunsei SE-500 panel together may require a charge controller.

Can the Sunsei 500 Solar Battery Charger drain my battery at night?

No. All Sunsei solar panels in the SE-150, SE-500 and SE-1500 range are equipped with a built-in diode, which prevents any reverse current.

Do I have to disconnect the panels from the battery when I drive or while I am recharging my battery with my generator?

No, Sunsei solar panels are designed to be connected to the battery permanently. There is no need to disconnect them when charging the batteries by other means such as AC chargers or your vehicle's generator or alternator.
