6.6 Inverter Start-up
Only start inverter after checking following.
a. Make sure all the DC and AC breakers and Isolators are in off
position b. AC cable from inverter to connection point is done correct.
c. All PV panels are connected to inverter correctly, unused DC connectors should be sealed
using covers provided.
Starting inverter.
a. Turn ON AC MCB
b. Turn ON DC Isolator and then AC Isolator
b. Inverter will start up automatically when PV arrays generates enough energy. Inverter goes through the
following three stages during normal start-up.
Waiting:
Inverter is waiting / checking PV arrays output DC voltage to be with adequate. At this time
DC voltage is with in range of DC100V-DC150V.
Checking:
Inverter checks AC grid conditions automatically when DC input voltage exceeds Start-
up voltage. Inverter then goes through the start-up count down.
Normal:
Inverter begins to operate normally with green light ON and feed power to grid,
LCD displays present output power. Inverter will stop feeding power to grid when PV output is not
enough for normal operation.
