Off-Grid Solar Inverter
The principle of operation of the Off-Grid Solar Inverter System is based on DSP technology. The latest DSP base circuit is used to control and monitor the type of conversion, i.e, Battery charging or Battery to Load / AC power conversion. The high conversion efficiency helps in longer battery backup. The advantage of low current harmonics and high PF is that it reduces the AC power bill (when working on mains) or reduced diesel consumption (when working on DG set)
