3 phase inverter for solar panels

 The working principle of off-grid inverters is simple. When sunlight hits the solar panels, it produces DC electricity. #3 phase inverter off grid       The off-grid inverter takes the DC power and converts it into AC power which can be used to power appliances, charge batteries, or other devices. #20kva solar inverter       Unlike grid-tied inverters, off-grid inverters do not require a connection to the utility grid. This means that any excess energy produced is stored in batteries for later use, rather than being fed back into the grid.

Quick Details:

Output power: 20kva

Input Voltage: 192/384VDC

Output Voltage: 380VAC

Micro-inverter design should focus on the following aspects.

1) Power density: Micro-inverters require high power density, and the overall circuit should have a small volume [1].

2) Conversion efficiency: Because the current conversion efficiency of photovoltaic cells is not high, every 1% increase in the efficiency of photovoltaic grid-connected equipment can bring huge economic value [1].

3) Reliability: The mean time to failure (MTFF) of centralized grid-connected inverters is usually 5 years, and the mean time to failure (MTBF) is about 10 years. The life of the photovoltaic cell is more than 20 years, so the life design index of the micro-inverter must be equivalent to that of the photovoltaic cell in order to reflect the advantages of this scheme. Its MTBF should be greater than 20 years, and MTFF should be greater than 10 years
