Color: 20000W Size: 12V Overview This hybrid wind and solar charge controller manages charging from a wind turbine and solar panels while protecting the battery and controller. It includes a dump load resistor for unloading wind output, supports multiple battery types including lithium, and offers MPPT boost charging for wind and PWM charging for solar. Key benefits Protects battery and controller: Automatic unloading with included dump load resistor prevents overcharging when wind output exceeds battery capacity. Multiple builtin protections guard against reverse connection, overcharge, under voltage, overload, open circuit, and lightning. Better charging efficiency: Wind turbine charging uses MPPT boost circuits to step up and extract charge at low wind speeds. Solar panel charging uses PWM. The independent stepup design maintains continuous, efficient charging. Broad battery compatibility: Works with lithium, GEL, and leadacid batteries and supports system voltages 12V, 24V, and 48V. Simple setup and reliable operation: The controller autoconfigures key parameters after battery connection and the upgraded software stabilizes voltage to reduce risk of battery damage. Clear monitoring and control: Larger display and four operation buttons make status and settings easy to read and adjust. Supports connection of DC loads with three working modes for flexible system control. Durable thermal design: Aluminum profile housing improves heat dissipation so the controller can selfcool during operation. Complete kit: Comes with 1 controller, 1 dump load resistor, 1 operation manual, 2 MC4 wrenches, and 2 resistor cables for immediate installation. Technical highlights Wind charging: MPPT with boost capability to maintain charging at low wind speeds Solar charging: PWM mode for panel input Battery voltages supported: 12V, 24V, 48V Protections: reverse charging protection for solar, battery reverse connect protection, overcharge and undervoltage protection, overload protection, open circuit protection, lightning protection Display: larger, clear screen with four control buttons Housing: aluminum profile for improved heat dissipation Installation notes Correct connection sequence: connect battery to controller first, then connect wind turbine and solar panel inputs. Usable battery types: GEL, leadacid, lithium Practical applications Offgrid home power: Combine a small wind turbine and solar array to charge batteries for lighting, appliances, and batterybased inverters. Marine and recreational vehicles: Manage wind and solar charging on boats or RVs where space and variable wind require efficient boost charging. Remote lighting and street lights: Reliable battery charging and automatic unloading protect the system during strong winds while keeping lights powered.
