DS Gunasekera Solar Energy - Solar Power - Sri Lanka - K Star Inverter


K- Star Inverter

This inverter is manufactured by Kstar New Energy Co; which is experienced in development of photovoltaic grid-connected generating sets. We hope this product can meet your demands and welcome you to put forward more suggestions on performance and functions of this product.

The photovoltaic grid-connected generating system is composed of a solar cell module, grid-connected inverter, metering devices and power distribution system. The solar energy is converted to DC electric power through the solar cell module, which is converted to sine-wave current synchronous with grid frequency and phase via the grid-connected inverter. Such electric power is then fed into the power grid. The photovoltaic grid connected inverter is the key equipment in solar power system.
