EPEVER 20 AMP MPPT Solar Power Charge Controller / Voltage Regulator

The solar controller regulates the voltage coming in from the solar panels and out to the battery. This will protect your battery bank from overcharging. This charge controller is a Maximum Power Point Tracking (MPPT) controller which utilizes PWM regulating technology. MPPT technology can lock on the point to harvest the maximum energy and deliver it to the battery. It compares and adjusts the operating points to attempt to locate the maximum power point of the array.
