gentralized grid-connected inverter power supply for photovoltaic power station

stable safe cheap high quality

Thanks to its unique benefits in environmental protection and economy, distributed power generation has drawn the attention of more and more people. During their adjustment of energy structure, a great many countries in the world have placed distributed power generation in a very important position. To satisfy the demand for energy due to the rapid development of the world economy, it is the natural development trend for the electric power industry to promote positively distributed power generation systems on the basis of the existing power grids.

The grid-connected inverter power supply system composed of SBTS-3500A series grid-connected inverter power supply modules and monitoring devices can be widely used for photovoltaic power stations at various power classes from 10 KW to100 KW.
