4.2 Energy Storage Inverter Function
4.2.1 Overheating And Cooling Operation
The inverter operates at set power when IGBT junction temperature is less than 105 C.
When the junction temperature of IGBT is higher than 105 C, the IGBT will be operated
at a set power percentage.
4.2.2 Cooling System Start-Up
The air-cooled system will start automatically when the energy storage inverter
reaches the rated power or temperature threshold.
4.2.3 Cold Start System
For off-line operating models, it is necessary to start directly through the battery to
supply power to the load, which can be operated manually.

4.3Introduction of Inverter Status
There are six states of energy storage inverter, as shown in Table 4-1 below.
Table 4-1 Status and Description
Status
Description
operation
Normal operation of energy storage inverter。
Standby
When the inverter receives standby instructions from the LCD screen
or the host computer, it turns to standby state in shutdown or
operation mode. When the AC and DC contactors of the inverter are
closed in standby state, the system is in hot standby state. When the
LCD screen or the host computer carries out relevant control, the
inverter can respond quickly.
fault
When the energy storage system fails, the inverter will stop working,
automatically disconnect the contactor on the AC and DC side, and
the main circuit will be disconnected from the battery, power grid or
load. In the fault state, the system always monitors whether the
fault is eliminated or not. If the fault is not eliminated, the system
maintains the fault state. If the fault is eliminated, it will enter
standby state after the default of 30 seconds.
Shutdown
If the energy storage inverter is in the normal "running" state, the
user can stop the energy storage inverter by issuing the stop
instruction from the host computer, or Turn off the key through the
LCD screen switch page.
Emergency
shutdown
In case of failure or emergency, press the emergency shutdown
button (EPO) to stop the inverter.
Shutdown
Energy Storage Inverter All Circuit Breakers Disconnect and Switch
Reset
When the energy storage inverter fails or the power module fails, it is forbidden to start
again through the touch screen.
It should be checked by power off to confirm that there is no problem, and then power on
again, otherwise it may damage the inverter.
