The Greef off-grid solar system is suitable for a wide range of application occasions and scenarios. It can be used for residential homes, cabins, RVs, boats, and even for emergency backup power. Its compact and modular design makes it easy to install and maintain, and it can be customized to meet the specific power needs of different users.
The Greef off-grid solar system is available in different load power options, including 5kW, 10KW,25kW,75KW,and 100kw, depending on the power requirements of the user. The battery voltage is 48VDC, and the output frequency can be set to either 50Hz or 60Hz, depending on the region of use.
The Greef off-grid solar system comes with a charge controller, which can be either MPPT or PWM, depending on the user's preference. The charge controller ensures that the batteries are charged efficiently and that the solar panels are protected from overcharging and over-discharging.
Off-grid systems work by combining wind power and photovoltaic power. When there is enough wind, wind turbines convert wind energy into electricity; at the same time, photovoltaic panels are converting sunlight into DC energy. Both types of power are first managed by a controller to ensure that they are used efficiently. The controller monitors the status of the batteries and stores excess power in the batteries in case it is needed. The inverter is responsible for converting DC power to AC power for AC loads such as household appliances. When there is insufficient wind, sunlight or an increase in load demand, the system releases power from the batteries to supplement the power supply, ensuring stable system operation. In this way, the PV off-grid system achieves an independent and sustainable power supply by integrating multiple renewable energy sources.
