Test Run
7.1 Pre-Boot Check
Before commissioning, a thorough inspection of the installation of the equipment should be
carried out, especially to check whether the DC and AC voltages meet the requirements of
the inverter, as well as whether the polarity and phase sequence are correct.
Check that all connections have met the requirements of the relevant standards and
specifications. And whether the system is well grounded. Grounding resistance is of great
importance to the safety of the whole system. It must be determined that the grounding
resistance meets the requirements before the first trial operation.
Before commissioning, it is necessary to ensure that all switches on the AC side are open.
Step 1: Check the inverter
The inverter needs to be checked before it is turned on.

Check the installation and wiring of the inverter according to Chapters 5 and 6.

Ensure that all AC and DC circuit breakers are disconnected.
Step 2: Check AC side voltage

Check whether the three phases of the inverter are connected correctly to the
three phases of the power grid.

Check whether the phase voltage and line voltage are within the predetermined
range and record the voltage value.

If possible, measure the total harmonic distortion (THD) and view the curve. If the
distortion is serious, the inverter may not work.
Step 3: Check DC side voltage

The DC side should be connected to the inverter from the battery pack to ensure
that the input polarity of each battery pack is correct.
The DC side voltage shall not exceed 850V.
If the voltage deviation is greater than 3%, it may be caused by load fluctuation, cable
damage or cable loosening on site.
