SYSTEMS AND METHODS FOR OPERATING A SOLAR CONTROLLER BATTERY CHARGER AND MAINTAINER

Systems/methods for operating a solar charger system. The system comprises: preventing, by a first circuit, damage to the solar charger system when a reverse polarity connection exists between a solar panel and the solar charger system; preventing, by a second circuit, damage to the solar charger system when a reverse polarity connection exists between the battery and the solar charger system; preventing, by a third circuit, damage to the battery when a temperature of a surrounding environment exceeds a pre-defined value while the battery is being charged by the solar charger system; and preventing, by a fourth circuit, back-feed from the battery without any voltage drop or loss while the battery is being charged by the solar charger system.
