Choose the right controller for the system
•
Rated Solar Current should be more than Rated
Power of Solar Panel.
•
Rated Load Current should be sufficient to cover
overall load current.
Choose right Inverter for the system
•
Make sure input voltage and out put voltage for the
system.
•
Rated Load Current should be sufficient to cover
overall load current.
