Firmware Upgrading
Preparation
Please ensure the inverter is steadily powered on.
Inverter must connect PV panels and keep the battery on through whole procedure of upgrading.
Please prepare a PC and an U-disk.
Warning!
Make sure the PV input power is more than 150V (operate the upgrade on a sunny day) , otherwise it may result in serious failing during upgrading.If the upgrading is broken off during operation, please ensure the inverter is steadily powered on and reinsert the U-disk.
Upgrading Steps:
Step1. Please contact our service support to get the update les, and extract it into your U-disk as follow:
“update\ARM\618.00050.00_Hybrid_X1G3_Manager_VX.XX_XX-XX.usb”;
“update\DSP\618.00084.00_Hybrid_X1G3_Master_VX.XX_XXXXXXXX”;
(Note: Vx.xx is version number, xxxxxxxx is le complation date. Don’t modify the program le name, or it may cause that the inverter can’t work anymore!)
Step2.
Press the “Enter” key for 5 seconds to enter Off Mode. Then unscrew the waterproof lid and insert U-disk into the “upgrade” port at the bottom of the inverter.
Step3.
The LCD will be shown as the picture below. Then press up and down to select the one that you want to upgrade and press “OK” to confirm to upgrade.
Update Update(DSP)

Step4.
After the upgrade is finished, the LCD will display “succeed”(only for DSP upgrades), please remember to pull off the U-disk, screw the waterproof lid and press the “Esc” to return to the Main interface. Then press the “Enter” key to exit Off Mode.

4.Set export control
Use Value:
10000W
This function allows the inverter able to control energy exported to the grid.
There are user value and factory value. The factory value is default which can not be charged by user. The user value setting by installer must be less than the factory value.
5.Set work mode
There are 5 work modes for choice.
· Self use/
· Remote Contol/
· Back Up Mode/
· Feed in Priority/
· Force Time Use/

Self Use
(default)
Remote Contol
Comment
The external generator generated power will be used to supply the local loads firstly, then to charge the battery. The redundant power will export to the public grid.
When there is no external generator supplied, battery will discharge for local loads firstly, and grid will supply power when the battery capacity is not enough.
It allows external control device to make the inverters remote cluster control through LAN port on the inverter in this work mode.
Back Up Mode
Battery will stop discharing to keep higher capacity when the grid is on. Only when the gird is off and the power generated is not enough, battery will start to discharge to keep the emergency load working normally.
This work mode applies to the area where suffering from blackout regularly.
Feed in Priority
Force Time Use
The priority of inverter output power is: feeding to the grid supplying the load charging the battery.
This work mode applies to the area with high feed-in tariff.
In this work mode the charging and discharging time can be set flexibly, and it also allows to choose whether charge from the grid or not.
6.Set EPS system(For E & I Version only)
EPS system
> Mute: No
Frequency: 50Hz
X1-Retro Fit inverter with E Version and I Version can work on the EPS mode.
EPS parameters can be set as below.
- “Mute”means you can set the warning of system which has entered EPS mode.
- ”No”means there will be a buzzing and it is the default value.
- ”Yes”means you choose to shut down the warning function.
Besides ,if the buzzing is sharp, it means EPS output is over loads.
“Frequency “here can be set 50Hz or 60Hz please based on correlative loads.
7.Set relay control(This function is being developed)
Relay Control
>Relay1 Setting
>Relay2 Setting
Relay Control is an optional function which can control designated load intelligently by consuming the surplus energy when feed in power reaches certain value.
This function can only be achieved with solax product “Smart Plug”.
For specific operation, please refer to “ Smart Plug user manual”.
Monitoring Operation
Solax provides two ways for users to choose: WiFi(optinal) and Ethernet(LAN)
WiFi(optinal)
Inverter provides a Wifi port which can collect data from inverter and transmit it to monitoring-website via a Pocket WiFi.
(Purchase the product from supplier if needed)

Router
WiFi Connection Steps:
Step1.
Plug Pocket Wifi into “WiFi” port at the bottom of the inverter.
Step2. Build the connection between the inverter and router.
Step3. Create an user account online.( Please check the Pocket WiFi user
manual for more details.)
Ethernet(LAN)
LAN communication is the standard communication interface. It can transmit the data between the router and inverter via the local network.
Application Occasion
This function is appliable for the below situation:
When the wifi signal is too weak to transmit data,user can
use LAN port for the monitoring with a data cable.
Note: The wifi module still needs to be connected
when using LAN connection.
