Before connecting to battey, please install a nonpolarized DC breaker to make sure inverter can be securely disconnected during maintanance.

of battery.
Current[A]| 50A

BMS PIN Denition
Communication interface bewteen inverter and battery is CAN with a RJ45 connector.

Note: The battery communication can only work when the battery BMS is compatible with the inverter.

Meter Connection

Meter connection diagram

Communication interface bewteen inverter and meter is RS485 with a Green terminal.
Meter connection step

1. Insert L/N wires and the 485cable into the meter.
2. Insert the other side of the cable into the meter port on the inverter.
   a. Unscrew the cable nut of Meter connector and insert two communication wires through it. b. Trip the insulation from the communication cable, and then insert it into connector.(Torque:0.2±0.1Nm)
   c. Insert connection into corresponding Meter terminal inside of the inverter.(Torque:0.4±0.1Nm)

Firmware Upgrading

Preparation
Please ensure the inverter is steadily powered on. Inverter must keep the battery on through whole procedure of upgrading. Please prepare a PC and an U-disk.
Warning!
Make sure the battery voltage is more than 180V , otherwise it may result in serious failing during upgrading.

1. Please contact our service support to get the update tract it into your U-disk as following:
   “update\ARM\618.00098.00_Hybrid_X3G3_Manager_VX.XX_XX-XX.usb”;
   “update\DSP\618.00096.00_Hybrid_G3X3_Master_VX.XX_XX-XX.hex”;

2. 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.

3. The LCD will be shown as the picture. Then press up and down to select the one that you want to upgrade and press “OK” to confirm to upgrade.

4. 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.

Earth Connection&Start Inverter

Start inverter

1. Ensure the inverter fixed well on the wall.
2. Make sure all the AC wirings are completed.
3. Make sure the meter is connected well.
4. Make sure the battery is connected well.
5. Make sure the external EPS contactor is connected well. (if needed)
6. Turn on the AC switch, EPS switch and battery switch.
7. Press the “Enter” key for five seconds to exit Off Mode. (The mode is factory defaulted as Off Mode)
   Inverter will start up automatically when the battery is discharging.
   Check the status of indicators and LCD screen. The left indicator should be blue and the indicator screen should display the main interface.

Start Guide

4.Set export control

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 4 work modes for choice.
Self use/ Back up mode/ Feed in Priority/ Force Time Use

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.
Back Up Mode| Battery will stop discharing to keep higher capacity when the grid is on. Only when the gird is off and PV energy 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| The priority of inverter output power is: ….supplying the load feeding to the grid charging the battery. ….This work mode applies to the area with high feed-in tariff.
Force Time Use| In this work mode the charging and discharging time can be set flexibly, and it also allows to select whether charge from the grid or not.**

6.Set EPS system(For E Version only)

X3-Retro Fit inverter with E 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.

Monitoring Operation

Solax provides two ways for users to choose: WiFi(optinal) and RS485
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)
Diagram

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.)(PH1 cross screwdriver .torque:1.5±0.1Nm)

COM
COM communication interface, which can be upgraded to man-machine communication interface.Output voltage, current, frequency, fault information and other operational information can be transferred to PC or other monitoring equipment through these interfaces.
Application Occasion
COM is one standard communication interface which can transmit the real data from inverter to PC or other monitoring equipments.

COM PIN Definition
Communication interface bewteen inverter and router is RS485 with a RJ45 connector.

COM Connection Steps: Please refer to BMS connection steps (for user manual page32) for COM connection. Please kindly noted the PIN definition and port position will be slightly different.
