Reliable Charge Controller for Off-Grid and Solar Setups
Take control of your solar energy with this high-efficiency Charge Controller. It supports 12V to 48V systems and uses MPPT (Maximum Power Point Tracking) to increase charging efficiency by up to 30% compared to PWM controllers. This means faster charging and better use of your solar panels—perfect for off-grid systems, RVs, and home backups.
It is compatible with LiFePO₄, AGM, GEL, and traditional lead-acid batteries. For best performance, pair it with a 51.2V 100Ah LiFePO₄ Battery to create a robust solar storage system. Add a 200W Foldable Solar Panel to complete your portable or off-grid energy solution.
This controller auto-detects voltage, features a real-time LCD display, and offers full protection from overcharging, overheating, and short circuits. Smart communications via RS485 and CANBus allow it to work with most inverter systems for a seamless solar power setup.
