20A Solar Charge Controller for Outdoor Solar Panels - Waterproof & Multifunctional - Ideal for RVs, Boats, and Off-Grid Power Systems

Feature:1. [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, compatible with 12V 24V system.2. [Good Electrical Conductivity] The internal material adopts copper terminal, which has better electrical conductivity and low loss, so you can use it with confidence.3. [Multifunctional] Large LCD screen display, dual USB ports, multi function control panel, high current overvoltage protection, intelligent clock timing, automatic voltage control.4. [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.5. [Widely Application] Widely used in solar off‑grid power supply systems such as homes, schools, streets, stations, power stations, pastoral areas, fields, etc.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 / 10.4ozHow to Use:System connection:1.
