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.
A:Power Connection Steps:

B:Communication Connection Steps:

Step1: Disassemble the GEN/Meter /BMS cable gland.Step2: Prepare a communication cable(without sheath)and insert the communication cable through the cable nut. Step3:Assemble the cable gland and screw the cable nut.Step4: Insert one RJ45 side of the cable into BMS port inside of inverter and the other side into RS485 or Can port of the battery.

Meter Connection

Meter connection diagram

Communication interface bewteen inverter and meter is RS485 with a RJ45 connector.

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.
   c. Insert connection into corresponding Meter terminal inside of the inverter.

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 an U-disk.
Warning!
Make sure the PV input power is more than 180V (operate the upgrade on a sunny day), 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 (Don’t modify the
   “update\ARM\618.00098.00_Hybrid_X3G3_Manager_VX.XX_XX-XX.usb”;
   “update\DSP\Hybrid_G3X3_Master.hex”;

2. Turn off the DC switch ,AC breaker and EPS breaker. Then unscrew the waterproof lid and insert U-disk into the”upgrade”as below.

3. Turn on DC switch , the LCD will shown as the picture. Then choose the one that you want to upgrade.

Start Guide

1. Set language

2. Set date time

3. Set the safety standard

4. Set export controlThis 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 modeThere are 4 work modes for choice.
   Self use/ Back up mode/ Feed in Priority/ Force Time UseParameter| Comment
   ---|---
   Self Use (default)| The PV 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 PV 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-Hyrbid 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.

7. Set relay control (The 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”.

Earth Connection & Start Inverter

Earth Connection Steps(mandatory):

Start inverter

1. Check the inverter is fixed well on the wall.
2. Make sure all the DC wirings and 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 DC switch at the bottom of the inverter to “ON” position.
7. Turn on the external DC and external AC switch.

Inverter will start up automatically when the PV panels generate enough energy or 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.

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)
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.) Ethernet(LAN)
LAN communication is the standard communication interface. It can transmit the data between the router and inverter via the l ocal 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. 

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

LAN Connection Steps:
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.
