MPPT Solar Boost Charging Controller for Electric Vehicles — 24V/36V/48V/60V/72V Stable, Safe Output

Product overview: MPPT solar charge boost controller designed for electric vehicle battery systems, delivering a stable and safe output across 24V, 36V, 48V, 60V and 72V battery voltages. Model selection guide: - 300W (standard): Use when solar array input power is less than or equal to 300W. Compatible output voltages: 24V / 36V / 48V / 60V / 72V. Default configured voltage: 48V. - 600W (high-power): Use when solar array input power is less than or equal to 600W. Compatible output voltages: 48V / 60V / 72V. Default configured voltage: 48V. Compatibility with the vehicle’s original charger: - There is no requirement to replace the electric vehicle’s existing mains charger or its interface. - It is recommended to connect the solar controller directly to the battery. The factory charger and the solar charger can charge the battery simultaneously without causing reverse current into the solar controller. - The solar controller must be connected between the solar panel and the battery; it cannot be used to directly charge or drive a motor. Installation precautions: - Maintain a safe separation from the vehicle’s motor controller and ensure strong electrical insulation between them to prevent leakage or interference affecting the controller. - Connect in this order: first attach the solar panel to the controller, then connect the battery to the controller. - Double-check polarity—do not reverse the positive and negative connections. - Mount the solar panel in a location free from obstructions to ensure optimal charging performance.
