Battery Connection

Battery Connection Diagram

Battery Breaker

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

BMS PIN Definition

Communication interface between inverter and battery is Rs485 or CAN with a RJ45 connector.
Note: The battery communication can only work when the battery BMS is compatible with the inverter.

Communication Connection Steps

Step1. Prepare a communication cable (without sheath) and insert the communication cable through the cable connector which can be found in the accessories package .
Step2. Crimp the communication cable with a Rj45 plug which is inside of the cable connector.

Step3. Insert the cable connector into BMS port inside of inverter and screw it tightly. Then insert other side of communication cable into RS485 or Can port on the battery. Battery BMS module(Pylontech: RS485 port; Triple Power: CAN port; Please check the battery manual for more details).

Earth Connection & Start Inverter

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 AC switch and EPS switch.
7. Turn on the PV/DC switch and battery switch.
8. Long-press the “Enter” key for five seconds to exit Off Mode. (The mode is Off Mode when you use it for the first time; factory default: Off Mode)

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.

Start Guide

1. Set language
2. Set date time
3. Set the safety standard
4. Set export control
5. Set work mode

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 set by installer must be less than the factory value.

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 make sure the size of U-disk is under 32G,and the format is fat 16 or fat 32.

Upgrading Steps

Step1. Please contact our service support to get the update files, 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 file completion date. Don’t modify the program file 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.
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.

Meter / CT Connection

Meter Connection Diagram

Meter Connection Steps

Step 1. Prepare a connector and two communication wires.

Step 2. Unscrew the nut of Meter connector and insert two communication wires through it.
Step 3. Trip the insulation from the communication wires, then insert one side of wires into pin1 and pin 2 holes of the 8 pin positive terminal which can be found in accessories package. And then screw them tightly.
Step 4. Insert the positive terminal into the corresponding negative terminal block inside of the inverter. And then screw it tightly. (Please refer to the meter instructions for the wiring of the meter.)

CT Connection Diagram

CT PIN Definition

The CT PIN definition is pin5 and pin6 shown as below.

CT Structural Decomposition

Step 1. Insert the side with two comm cables of CT into the Meter port on the inverter, and screw down the screw cap tightly (refer to meter steps).
Step 2. Trip the insulation from the communication wires, then insert one side of wires into pin5 and pin 6 holes of the 8 pin positive terminal which can be found in accessories package. And then screw them tightly. (refer to meter steps)
Step 3. Insert the positive terminal into the corresponding negative terminal block inside of the inverter. And then screw it tightly. (refer to meter steps)

Monitoring Operation

Solax provides two ways for users to choose: WiFi (Optimal) and Ethernet (LAN)

WiFi (Optimal)

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

Step 1. Plug Pocket Wifi into “WiFi” port at the bottom of the inverter.
Step 2. Build the connection between the inverter and router.
Step 3. 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.

LAN PIN Definition

Communication interface between inverter and router is RS485 with a RJ45 connector.

LAN Connection Steps

Please refer to BMS connection steps for LAN connection. Please kindly noted the PIN definition and port position will be slightly different.
