14. SYSTEM DESCRIPTION
14.1 System Details
PCU is single phase output, Solar Inverter System. In normal (Hybrid) mode, PCU
operates from battery or array power source and produces single phase AC output to
fulfill the load requirement MPPT based array charger, supplies the DC power for
battery charging as well as for the inverter.
When Battery will be at battery low set point then Grid/input source will get triggered
automatically at certain predetermined battery voltage level. Grid Input source
starts battery charging as well as take care of output load and sufficient battery
charge level.
14.2 Priority
Solar / Battery / Grid & Solar / Grid / Battery
Automatic Select
System Comprises the following boards.
1. Control Board:- It controls operating of MPPT charger and inverter. It contains
power modules of MPPT and inverter. MPPT receives DC supply from solar array
and provides charging voltage to battery and DC voltage for inverter operation. This
board also contains power relays for grid and inverter, based on signal from
controller. Hence, operation is controller and output is available at load.
2. Display Board:- It received all inputs from control board. It display array, battery,
inverter & grid parameters.
