Why PV-DG Solution Required?
Due to Anti-Islanding protection, when the grid gets disconnected then solar inverter stops power generation.
If consumer is having Diesel Generator (DG) to provide a power to load, By using PV-DG solution solar plant can cater partial load which will reduce load on Diesel generator which directly helps fuel saving thus operation cost reduction.
PV-DG Sync controller understands DG power from the energy meter installed at DG LT which has been connected to PV-DG sync controller over RS485.
It will ensure back feeding of power from PV to diesel generator in case the load demand comes down, thereby maintaining system stability when running PV plant with DG generator in the absence of the grid.
