The Solar Panel Voltage Regulator – Model 5310-10 is intended for float charging of lead-acid batteries. The Solar Panel Voltage Regulators are compatible with solar arrays having a current output less than or equal to 3 Amperes. The Solar Panel Voltage Regulators may be used with any size lead-acid battery. Unlike some other regulators, the 5310-10 Solar Panel Voltage Regulator will not damage your battery due to overcharging.
The Solar Panel Voltage Regulator will act as a blocking diode when the battery voltage is greater than the solar array voltage. There will be no reverse current flow. The Solar Panel Voltage Regulator draws no current from the battery.
The Solar Panel Voltage Regulators include a thermal switch which will momentarily interrupt the current flow when the 5310-10 is dissipating too much heat.
While the Solar Panel Voltage Regulator can be installed outdoors, it is best to choose a mounting position which is protected from direct falling rain and from direct sunlight. This can usually be accomplished by mounting the Solar Panel Voltage Regulator on the backside of the solar panel.
