Installation and Operation Manual 16
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 lower than 150V but higher than 120V,
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 150V, the inverter will transfer to running status after
self test, and meanwhile start to feed energy to municipal Grid.
