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

Feature: 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. Specification: Item Type: Solar charge controller Material: ABS Charging Type: MPPT Working Voltage: 12V 24V automatic identification Maximum Charge And Discharge Current: 20A Solar Panel Maximum Open Circuit Voltage: 60V (at the lowest temperature) Maximum Photovoltaic Input Power: 260W (12V), 520W (24V) USB Output Voltage: 5V 2A x 2 Standby Consumption: less than 50mA Working Temperature: 20 celsius +55 celsius Terminal Wire Gauge: 10msquare meters 7AWG Proof Grade: IP30 Rechargeable Battery: Gel battery, li battery and more Applicable Scenarios: Solar photovoltaic systems such as home power generation, base stations, RVs, yachts, ships, etc..
