5.7 Start up and Shut down Inverter
5.7.1 Start Up the Inverter
1.
Follow the installation standard from previous chapter strictly to connect the photovoltaic panels and AC
power grid to inverter.
2.
Using multimeter to check whether AC side and DC side voltage have met the inverter start voltage.
3.
Turn ON DC switch (if applicable), LED indicators will be lit up.
4. Select count grid code through the APP, (please contact your local grid operator for which region to select).
Inverter will be in self-testing mode, if inverter has met all the grid connecting condition, inverter will connect
to grid and generate power automatically.
5.7.2 Shut Down the Inverter
1.
Automatically shut down, when the solar light intensity is not strong enough during sunrise and sunset or
the output voltage of photovoltaic system is less than the minimum input power of inverter, inverter will shut
down automatically.
2. Shut down manually, disconnect AC side circuit breaker first, if multiple inverters are connected, disconnect
the minor circuit breaker prior to disconnection of main circuit breaker. Disconnect the DC switch after
inverter has reported grid connection lost alarm.
5.8 AFCI (Optional)
The inverter is equipped with arc-fault circuit interrupter (AFCI). With AFCI protection, when there is an arc
signal on the DC side due to aging of the cable or loose contact, R6 series can quickly detect and cut off the
power to prevent fire, making the PV system run more safely.
