The SOGTICPS controller features a smart MPPT tracking algorithm that maximizes the energy from the solar PV module(s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging. The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults. Its included LCD screen lets you monitor your system with ease. Product Description 1.MPPT tracking 2.limited current charging mode 3. Instantaneous large current startup of capacitive loads is supported 4.
