Flexible load modes: switch mode, pure light-control mode, and timed lighting control mode to match your needs and save energy. Broad battery compatibility: supports lead-acid gel, ternary lithium, lithium iron phosphate (LiFePO4), and other common chemistries. Lithium-specific safety and stabilized charging: activation function and voltage-stabilized charging protect battery cells and prevent controller crashes. If the battery isn’t powering the controller, it draws power from the PV source to maintain operation. Real-time MPPT optimization: quickly tracks the maximum power point in any environment, delivering real-time energy from the solar panel and significantly improving overall system efficiency. Compact, reliable design: easy to install in a variety of setups while delivering steady performance. Use scenarios: - Off-grid cabin: lighting and essential loads powered by a compact solar array. - Remote farms: irrigation or perimeter/security lighting with dependable battery support. - RVs/boats: solar charging and battery maintenance during travel.
