Check Voltage


Use a DC Multimeter and measure the potential between Pins 4 (GND) and 6 (V+) of the Battery Pack’s PWR OUT port. Healthy operational pack voltages range from 12V to approximately 14.9V, depending on the amount of direct sunlight and the age/health of the installed battery. Significantly lower observed voltages may warrant a battery replacement (every 3-5 years standard) or solar regulator replacement (only in event of failure).
