12V/24V Solar Charge Controller

Features
High converting efficiency higher than 99.5% for minimizing energy loss. Build-in MPPT tracker for optimizing the power transformation. Reversed current protection for preventing equipment damage. Automatic battery temperature compensation for long-term reliability. Capable of selecting different charging mode for various type of batteries. Capable of connecting additional DC load for wider applications.

Three stage charge control system (bulk, absorption, and float mode) with temperature compensation. LED indicators display charge status in real time. Pulse Width Modulation (PWM) topology combined with a multi-stage charge control algorithm leads to superior charging and enhanced battery performance.
