Abstract

The invention discloses a multi-energy-converted inversion device and a control method thereof. The multi-energy-converted inversion device comprises a photovoltaic input module, an electric supply input module, a storage battery input module, an invert output module, and a converter, wherein the converter is a bidirectional converter; the electric supply input module transmits electric power to the invert output module through the converter; the photovoltaic input module transmits electric power to the electric supply input module through the converter. According to the multi-energy-converted inversion device, the output electric power of solar energy, a power grid and a storage battery can be automatically adjusted according to different conditions, so that besides ensuring the electric power supply required for a load, the energy of the solar energy, the power grid and the storage battery are reasonably and fully utilized, the energy utilization ratio is greatly improved, and the insufficiency, the imbalance and the low efficiency of energy utilization are avoided.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation equipment, in particular to an inverter device for multi-energy conversion and a control method thereof. Background technique [0002] With the development of technology and the development of energy saving and emission reduction, photovoltaic power generation has received more and more attention and attention. Photovoltaic inverter devices can convert solar energy into electrical energy and are important devices in photovoltaic power generation systems. There are many kinds of photovoltaic inverter devices, among which off-grid photovoltaic inverter devices are widely used because they have both off-grid and grid-connected modes and are flexible to use. The off-grid photovoltaic inverter device is in grid-connected mode when there is mains power, and the power is supplied by the grid to the load, and solar energy can be transmitted to the grid; output energy to the load. However, th...
