ON GRID POWER PLANT
ON GRID POWER PLANT
The Dc power from PV panel goes to a grid interactive (grid-tied) inverter which converts the PV panel DC power to 220 volts AC power that is compatible with the power grid.
AC power from inverter is supplied to the household power needs.
If the PV system is generating more power than the house can use, the excess is sent out over the grid to supply others. (Net metering system)
If the house needs more power than the PV system can supply then the extra is drawn from the grid as usual.
Grid tied systems only work when the grid is up. If the grid power goes out, the grid tie inverter is required to shut down immediately.

How does it work?
PV Grid connected inverters operate at a lower, safer voltage from the PV array , while having the advantages of reliability, flexibility and improved energy yield. Using lower voltages on the PV side means there are lower voltages in your roof eliminating high voltage hazards and giving peace of mind to installers and service personnel.
By using short multiple strings of panels, PV Grid connected inverters make sure that there are more paths for electricity to flow, which ensure minimal power loss due to varying environmental or panel conditions.
Working Principle
Installing the Grid tie solar inverter consists of mounting it to the wall and connecting the DC input to a PV array and AC output to the utility.
OFF GRID POWER PLANT
Solar power conditioning unit(PCU) is an integrated system consisting of a solar charge controller. Inverter and a Grid charger. It providing the facility to charge the battery bank either though solar or Grid/DG set. The PCU continuously monitors the state of battery voltage, solar power output and the loads. Due to sustained usage of power , when the batter voltage falls below a preset level, the PCU will automatically transfer the load to the Grid/DG power and also charge the batteries through the in-built Grid charger. Once the batteries are charged to the preset level, the PCU cuts off the Grid /DG power from the system and will restore to feeding the loads from the battery bank 7 continue to charge the battery bank from the available solar power.
