Shut Down Inverter - KEHUA TECH SPI-B X2 Series User Manual

5 Startup and Shutdown
Step 1 Switch on the DC switch on the inverter and the project site. When the PV string provides enough
startup voltage, the inverter will start and the indicator will be on.
Step 2 Switch on the AC switch between inverter and grid, if the indicator is not red, that is there is no fault.
Step 3 When the DC and AC power are all normal, the inverter will prepare to start grid-tied. Check the
inverter parameters and the grid parameters, if they are in the normal range, a moment later, the
inverter will perform the insulation impendence detection.
Step 4 A moment later, the inverter will generate power normally.
----End
If it needs to use battery to start inverter (when starting inverter for the first time, it doesn't support using
battery to start inverter), please do as follows.
When PV has no input or the input voltage is less than 180V, press the "POWER" button of each
1.
battery for 10s, and the indicator will be on.
2. When the DC and AC power are all normal, the inverter will prepare to start grid-tied. Check the
inverter parameters and the grid parameters, if they are in the normal range, a moment later, the
inverter will perform the insulation impendence detection.
3. A moment later, the inverter will generate power normally.

5.3 Shut Down Inverter

When the inverter works normally, do not switch off the DC switch and AC switch with load to avoid
switch damage for arc. At worst, the inverter may be damaged.
Step 1 Switch off the DC switch on the inverter and project site, a moment later, the indicator will be off.
Step 2 Disconnect the connection between the inverter and grid.
