20A MPPT Solar Charge Controller Regulator 260W 12V 520W 24V Parameter Adjustable Temp Detect for Gel Lithium Battery

1、High 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. 2、Full Electronic Protection: Battery reverse connection protection PV reverse connection protection PV short circuit protection charging overcurrent protection. 3、Multifunctional: 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. 4、Temperature Compensation: Built in temperature detection through derating charging no need for a fan and stable operation in extreme temperature environments. 5、Current 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. 6、Parameters 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.
