Product Introduction The DC automatic transfer device obtains DC electrical energy from photovoltaic panels. It detects the online status of the power grid and automatically outputs to solar pump inverter or the on-grid inverter. First，Through the solar pump inverter, it is transformed into electrical energy suitable for the water pump motor, driving the water pump to working. Second, through the on-grid inverter, it is transformed into electrical energy suitable for the power grid and fed back to the grid. When the light is weak in the early morning and evening, the photovoltaic energy cannot meet the demand of the water pump inverter. However, the on-grid inverter can track the maximum power point of the photovoltaic energy and generate electricity entirely. When the light is abundant at noon, not only can it meet the demand for the solar pump inverter to operate at full load, but the excess solar energy can also be used for power generation through the on-grid inverter.100% utilization of solar energy can be truly achieved. Product Features: IP65 protection rating, suitable for harsh application environments Operating temperature: -25 to 60°C RS485 interface Maximum operating voltage of 880V, compatible with most solar system configurations. Full protection function (Under-voltage, over-voltage, over-current, and over-heating) Auto working, maintain free System Application Diagram Technical Parameters:
