Installation and Operation Manual

6.1 Trial Operation
The inverter can be activated only after the following inspections are
well executed:
1.
Correct connection for AC cables.
2.
All solar arrays are connected with the inverter correctly.
3.
Tighten all screws.
4.
Turn on the breaker between DC and AC.
5.
The inverter will automatically get started once PV arrays generate
enough voltage.
6.2 Working Status
Working status is divided into 3 kinds: normal working status, faulty
status, and termination status.
1. Normal Working Status
There are two modes: standby status and running status for this stage.
Under this mode, the system is running in normal status. Meanwhile
tracking all functioning data to keep the system running in its best
status.
Once PV array’s voltage is
less than start voltage,
, the inverter will
be in standby status, at this period the inverter starts to run and all
test functions get ready, but it doesn’t feed power to municipal
Electrical Grid. When PV array’s voltage
is higher than start
voltage,
, the inverter will transfer to running status after self test,
and meanwhile start to feed energy to municipal Grid.
