Chapter V Commissioning and Operation 21
5.1.1 Automatic startup
In automatic startup, the storage inverter system will automatically inspect and judge startup conditions. If the system function
is normal and it meets the system setting conditions, it will start automatically. If the voltage of power grid is too low or high,
the frequency is abnormal, DC voltage is too low or high, the storage inverter will make an alarm, shut down automatically and
stop providing power outside.
After meeting the following conditions, the storage inverter will restart automatically, and the output is recovered.
 DC voltage is normal.
 The voltage of power grid is normal in on-grid mode, or there is no voltage of power grid in off-grid mode.
 Operation mode setting is correct.
 There is no other alarm fault.
If automatic startup is not set in storage inverter, users can start the device by hands through touch panel.
Startup and shutdown
The storage inverter must be installed completely and commissioned by engineers. External power switches have been closed,
and then startup steps can be conducted.
5.2.1 Check before startup
Before startup, check the device according to the following steps:
1) Visually inspect and ensure that no damage sign is in external part of the module, and DC breaker and AC breaker are at
“OFF” position.
2) Complete installation according to Chapter IV, and check whether DC input wiring and AC output wiring in the storage
inverter are normal, and the grounding is good.
3) Check whether battery voltage is normal.
4) Check whether phase voltage and wire voltage in power grid side are in the normal range, and record the voltage.
5.2.2
Startup steps
These startup steps are applicable to the circumstance that the storage inverter system is in outage state and can be started.
Operation steps are as follows:
1) Close output switch of battery cabinet and connect power supply to DC port of the device.
2) Close DC breaker. Green indicator light flickers in green. After about 10s, the red indicator light is always on in red. At this
moment, LCD will indicate the warning information such as “under-voltage of power grid” and “abnormal power grid frequency”.
If step 2 and step 3 are conducted before the red light is always on, the flickering in red will not appear.
3) Set monitoring parameter to control operation mode. See setting information in 6.2.
4) After step 3 is conducted, return to “main wiring diagram” On HMI and start DC/AC modules.
5) According to the current operation mode setting and DC input, the host will automatically operate and display.
