Specification:Item Type: Solar Panel ControllerMaterial: Shell plastic + back plate ironProduct Size: Approx. 16.7 x 9 x 4 cm / 6.6 x 3.5 x 1.6 in (manual measurement allowable error)Display Mode: LCD screen Current: 20AVoltage: 12V / 24V automatic identificationApplicable Solar Panels: 12V is suitable for 18V solar panels, 24V is suitable for 36V solar panelsMaximum PV Voltage: 12V battery, up to 23V, 24V battery, up to 46V (up to 50V without load)Maximum PV Input Power: (12V) 260W, (24V) 520WWorking Temperature: -20℃ to 55℃Weight: Approx. 295g / 10.4ozPackage List:1 x Controller1 x ManualNote:1. The controller is 12V/24V automatic identification, when installing for the first time, please make sure that the battery has enough voltage so that the controller can identify the correct battery type. In order to the life of the battery, once the battery voltage is lower than 8V, the solar controller will automatically shut down.2. Install the controller as close to the battery as possible to avoid voltage drop caused by too long wires and affect the normal voltage judgment.3. This controller is only suitable for various lead acid batteries (including openings, , gels, etc.), please do not use it with other batteries (including lithium batteries, nickel‑hydrogen batteries, etc.).4. The controller can only use photovoltaic panels as the charging source, please do not use DC or other power sources as the charging source.5. The controller will generate heat when it is running. The operating temperature of the controller is ‑20°C to +55°C. Please install the controller on a flat, well ventilated surfaces.6. The LCD display of this controller has an error of 0.2V‑0.3V, but this is normal.

[Good Electrical Conductivity] The internal material adopts copper terminal, which has better electrical conductivity and low loss, so you can use it with confidence.

[Multifunctional] Large LCD screen display, dual USB ports, multi function control panel, high current overvoltage protection, intelligent clock timing, automatic voltage control.

[12V 24V Automatic Identification] Using industrial grade main control chip, high quality components improve system performance, the highest conversion efficiency is 98%, ultra fast tracking speed, the controller is 12V 24V automatic identification, compa

[Simple To Install] The charge controller should be connected to the battery first, then the solar panel, and finally the load, in the reverse order of removal and wiring.

[Widely Application] Widely used in solar off‑grid power supply systems such as homes, schools, streets, stations, power stations, pastoral areas, fields, etc.
