9.2 Check the Running State

Prerequisites
Before switching on the AC breaker between the inverter and the grid, check whether the
AC voltage on the power grid side of the AC breaker is within the specified range.
Please select the acceptance of installation on site when the light intensity is strong.
Procedure
1.
Ensure that the all breakers connecting to or on the product are OFF.
2. Check the grid-connected state of the product
Short press the power button on the left side of battery pack, then switch on the
battery breaker on the right side of battery pack.
Switch on the battery breaker which is located at the bottom middle inverter.
Switch on the PV switch which is located at the bottom left inverter.
Switch on the external AC breaker between the grid and the inverter.
Set the operating parameters through the APP.
Wait about 3 minutes for the inverter to enter the grid-connected state, and observe
Acceptance Criteria
The battery pack and inverter are mounted correctly,
securely, and reliably.
The WiFi module is mounted correctly, securely,
and reliably
Cables are routed properly as required by the
customer.
Cable ties are secured evenly and no burr exists.
The ground cable is connected correctly, securely,
and reliably.
All breakers connecting to or on the product are
OFF.
The AC cable, PV cable, battery cable, and
communication cables are connected correctly,
securely, and reliably.

the indicators states on the display panel of the inverter. At this time, the following 4 LEDs
("SYSTEM", "BATTERY", "METER", "COM") on the display panel is always on.
3.
Check the UPS state of the product
Switch off the external AC breaker between the grid and the inverter.
The inverter will enter the UPS state at once, and observe the indicators states on
the display panel of the inverter. At this time, the following 3 LEDs ("SYSTEM",
"BATTERY", "COM") on the display panel is always on.
Check the wiring of the backup load
Switch on the external AC breaker between the load and the inverter.
Please connect a low-power electrical appliance to the socket of backup load. If the
electrical appliance can work normally, it means that the wiring of the backup has been
installed successfully.
NOTICE
During commissioning, if the LED indictors on the display panel of the inverter or
the battery pack show red, please refer to Section 10.2 for troubleshooting.
9.3 Powering Off the Product
DANGER
After the inverter and battery pack is powered off, the remaining electricity and heat may
still cause electric shocks and body burns. Therefore, put on protective gloves and operate
the product 5 minutes after the power-off.
Procedure
1. Long press the power button for 6 seconds on the left side of battery pack, then
switch off the battery breaker on the right side of battery pack.
2.
Switch off the battery breaker which is at the bottom middle inverter.
3. Switch off the PV switch at the bottom left of the inverter.
4. Switch off the PV switch between the PV string and the inverter if there is any.
5. Switch off the AC breaker between the inverter and the load.
6. Switch off the AC breaker between the inverter and the grid.
