This is a multi-functional off grid photovoltaic inverter, integrated with MPPT photovoltaic charging controller, high-frequency pure sine wave inverter and UPS functional module, which is very suitable for off grid backup power supply and self use system. The design of high-frequency transformer enables the machine to provide reliable power conversion in a small size. This inverter can also operate in battery free mode. The WiFi/GPRS module is a plug and play monitoring device installed on the inverter. With this device, users can monitor the operation status of the photovoltaic system anytime, anywhere through mobile phones or websites.
