After all connections done , gently press the ‘wake up’ KEY of the lithium battery. While the ‘status’ LED
indicator turns green, the battery starts working.
5.5 Grounding
PV Array Grounding
Grounding conductor of PV panel brackets must be firmly connected to earth at both PV array side and inverter
side. The sectional area of grounding conductor should be equal to the sectional area of DC grounding conductor.
DC Grounding
Select the DC Grounding mode according to the local standard and use the PV grounding terminal box and DC Grounding
wires of the same specification.
Grounding Device
If the positive pole or the negative pole of PV array need to be grounded in the PV system, the inverter output
should be insulated by Isolation Transformer.
Connection as below:

6 Commissioning
6.1 Commissioning of Energy storage machine
1) Connect the input side terminal to PV modules.
2) Connect the output side terminal to PV inverters.
3) Connect the AC plug to grid.
Chart 6.1
4) If the energy storage machine’s input voltage is 230±15%V and meanwhile fail to connect battery.LCD
will display information as follows:
storage plus standby status information.
LCD will disply“bat voltage low”status.
Please check all the information on the LCD, through knocking you’ll see various parameters
5) Turn off DC switch and connect to battery, turn on inverter’s DC switch, both energy storage machine
and inverter will operate automatically.
6) In normal contra variant mode, LCD would scroll display the state information, LED area would display
the current state. The green LED light would turn on constantly in the same time.
7) Finish commissioning.
