Buy a low-price 12V vertical air wind turbine online, a 3-blade vertical wind turbine rated at 300 watt, with a starting wind speed of 2m/s and a rated wind speed of 12m/s. This vertical axis turbine is compact, lightweight and easy to install, making it an excellent choice for residential, commercial and industrial applications.
The battery is charged by the wind turbine and solar panels through the controller, and the DC output port of the controller directly supplies power to the DC load. On days without wind or light, the power output by the wind turbine and solar panels is not enough to charge the battery, which can cause the battery to be under-voltage. In this case, the controller output dry contact control signal automatically switches to the grid power to supply the load.
