1High Efficiency: Combining a variety of tracking algorithms, it can quickly locate the best working point of the I?V curve, with faster response speed, higher tracking efficiency and circuit energy conversion efficiency. 2Full Electronic Protection: Battery reverse connection protection, Pv reverse connection protection, Pv short circuit protection, charging overcurrent protection. 3Multifunctional: Support for Modbus protocol. You can connect an external Lcd screen or a Bluetooth module to view the device running data and status, and support to modify the controller parameters. 4Temperature Compensation: Built in temperature detection, through derating charging, no need for a fan, and stable operation in extreme temperature environments. 5Current Limiting Charging Mode: When the power of the solar panel is too large and the charging current is higher than the rated value, the controller automatically reduces the charging power to make the solar panel work under the rated charging current. 6Parameters Adjustable: Support Gel batteries and lithium batteries, etc., users can customize the charging parameters. Suitable for solar photovoltaic systems such as home power generation, base stations, RVs, yachts, ships, etc.
