Earth Connection&Start Inverter
Earth Connection Steps(mandatory):
Turn on the AC switch, EPS switch and battery switch.
Make sure the external EPS contactor is connected well. (if needed)
Make sure the battery is connected well.
Make sure the meter is connected well.
Make sure all the AC wirings are completed.
Check the inverter is fixed well on the wall.
Startinverter
Inverter will start up automatically when the battery is dicharging.
Check the status of indicators and LCD screen. The left indicator should
be blue and the indicator screen should display the main interface.

There are user value and factory value. The factor y 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/

·Back Up Mode/
·Feed in Priority/
·Force Time Use/
6.Set EPS system(For E & I Version only)
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 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”.

Inve rter
It allows external control device to make the inverters remote cluster control
through LAN port on the inverter in this work 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.
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.
Self Use
(default)
Force Time Use
Remote Contol
Back Up Mode
Feed in Priority
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.
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.

Please refer to BMS connection steps (for user manual page32) for LAN connection. Please kindly noted the PIN definition and port
position will be slightly different.
Ethernet(LAN)
LAN communication is the standard communication interface. It can transmit the data between the router and inverter via the
local network.
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.
Prepa ratio n
Warni ng!
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.
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_XXXX XXXX”;
(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!)
