FSI series :pure sine wave hybrid solar inverter with MPPT charge controller

The electric energy generated by various forms of new energy needs to be processed by the electric energy conversion device to meet the relevant standards and then sent to the power grid. Among the various forms of new energy power generation, photovoltaic power generation occupies a large proportion, and inverters have received extensive attention as a DC-AC conversion device. Inverters can be classified into grid-connected inverters, grid-connected/off-grid inverters, uninterruptible power supplies and so on according to their functional classification. When the grid is normal, the grid-connected inverter can supply power to the load while inputting power to the grid. If the grid is abnormal at one point, the grid-connected inverter will stop working immediately. The uninterrupted power supply of key loads in the system may require an uninterruptible power supply to support Moreover, grid-connected inverters have the disadvantage of low power utilization.

The grid-connected/off-grid inverter has two different working modes: grid-connected and off-grid. When the large power grid supplies power normally, the grid-connected/off-grid inverter is connected to the grid and operates according to different working conditions. It works in state and realizes energy transmission with the large power grid. After the grid fails, the grid-connected/off-grid inverter system can be disconnected from the grid and then allow the reserve battery to supply power for key loads to improve power supply reliability. During the off-grid process, the load is required to supply uninterrupted power supply to achieve rapid switching from grid-connected mode to off-grid mode.
