4. INVERTER START-UP AND OPERATION
WARNING:
Do not place any items on JSI inverte
r
during operation.
When the inverte
r
is operating, do not touch the heatsink since some
parts may become very hot.
Step 1: Ensure that the AC cable and DC cable is connected correctly, unused DC
plugs and AC terminal cover are sealed.
Step 2: Connect the DC and AC switches. The inverter starts up automatically
when DC-power from the PV strings is sufficient.
Once the solar inverter starts, it enters one of the following 3 states in turn:
Standby
: The PV string can only provide just enough voltage to minimum
requirements of the internal controller unit.
Waiting: When the PV string DC voltage is greater than 100V, The inverter enters
a “waiting” state and attempts to connect to the grid.
Normal: When PV string DC voltage is greater than 150V, Inverter operates in the
normal state.
The Inverter will keep MPPT function and deliver power to AC Grid when it is in
normal operation. Maybe it will stop under the situation of low input DC-power,
Don’t worry, it will automatically restart again when DC-power from the PV string is
sufficient.
Error or Warning status
Inverter is designed to be user-friendly, therefore, the error or warning status of
the Inverter can be easily understood by reading the information shown on the
front panel display. All possible messages are shown in the following table.
