OFF GRID SYSTEM
In areas where there is absence of Grid or the grid is unstable or faces load shdding an ON Grid system can be connected with a backup inverter and a battery bank.
This kind of system comprises of a PV Array, an MPPT Inverter, a Backup Inverter and a Battery bank.
PV Array Produces DC Voltage and is connected to the MPPT Inveter.
The MPPT Inveter converts DC Volts into 230VAC Voltage
AC Power is Fed to the loads and also through the backup inverter to charge the batteries.
Excess energy can be fed to the public Grid if it is present else the system continues to work with or without the grid present.
