Inverter Manipulation
NOTE!
If the left indicator do no turn green please check the below points:
- All the connections are correct.
- All the external breakers are switched on.
- The DC switch on the inverter is in the “ON” position.
Step 1.
Switch the manual bypass breaker to connect with grid side.
Step 2
.
Turn off the Grid breaker and the battery breaker.
Step 3
.
Turn off the DC switch at the bottom of the inverter to the “OFF” position.
Step 4
.
Turn off the main switch if needed.
8.2 Start Inverter
Step 2. Turn on the DC switch at the bottom of the inverter.
Step 5. Select the wanted voltage through the screen, such as 240V.
Step 6. Then choose the grid standard, IEEE1547 or RULE21.
Step 7.
The inverter will start up and ISO, IMI, Relay will start self-checking
automatically when the PV panels generate enough power or the battery is
discharging.
Step 8. Check the status of indicators and LCD screen. The left indicator should
be green and the indicator screen should display the main interface.
Step 9.
Set Wi-Fi / LAN according to Wi-Fi / LAN user manual. (if needed)

Step 3. Turn on the AC switch.
9 Firmware Upgrading
The inverter firmware can be upgraded via a U-disk.
Ensure the inverter is powered on.
The inverter must be connected to the PV panels and the battery must be
operating while the rmware upgrade is in progress.
Please prepare a PC and an U-disk.
9.1 Preparation
WARNING!
Make sure the PV input power is more than 150V (operate the
upgrade on a sunny day), otherwise it may result in serious failure
during upgrading.
Step 1. Contact our service support to get the update les, and extract it into your
U-disk as follow:
“update\ARM\xxx.xxxxx.xx_Hybrid_A1_Manager_Vx.xx_xxxx.usb”,
“update\DSP_Master\xxx.xxxxx.xx_Hybrid_A1_Master_Vx.xx_xxxx.hex”,
“update\DSP_Slave\xxx.xxxxx.xx_Hybrid_A1_Slave_Vx.xx_xxxx.hex”,
“update\BMS_Slave\xxx.xxxxx._SolaxBat_Sxx_xxxx_Vx.xx_xxxx.hex”;
“update\BMS_Master\xxx.xxxxx._SolaxBat_M_xxxx_Vx.xx_xxxx.hex”.
(xxx.xxxxx.xx is the P/N, Vx.xx is version number, xxxx is le complation date)
9.2 Upgrading Steps
Software version can be found in the “About” display.
The way to check software version from the “About” screen:
1) Access the “About” display by pressing “OK” button when the LCD shows the
