Module inverter for solar inverter

The module inverter connects each photovoltaic module with an inverter, and each module has a separate maximum power peak tracking, so that the cooperation between the module and the inverter is better. Generally used for 50W to 400W photovoltaic power stations, the total efficiency is lower than string inverters. Because it is connected in parallel at the AC, this increases the complexity of the wiring on the AC side and makes maintenance difficult. Another problem that needs to be solved is how to connect to the grid more effectively. The simple way is to directly connect to the grid through ordinary AC outlets. This can reduce costs and equipment installation. In doing so, the power company may object to the direct connection of the power generating device to the ordinary socket of the ordinary household user. Another safety-related factor is whether an isolation transformer (high or low frequency) is needed or whether a transformerless inverter is allowed. This inverter is most widely used in glass curtain walls.
