Serial Port Connections
Ports Definition: Communication interfaces between the inverter and Meter/Battery/DRM/485 are as follows with RJ45 connectors which should be inserted into the corresponding port in the inverter.
| PIN | Port | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|---|
| CT | CT+ | X | X | X | X | X | X | X | X |
| CT- | X | X | X | X | X | X | X | X | |
| Meter | X | X | X | X | X | GND | 485A | 485B | |
| BMS | NTC | GND | 485A | 485B | GND | BMS_CANH | BMS_CANH | GND | |
| DRM | DRM1/5 | DRM2/6 | DRM3/7 | DRM4/8 | +3.3V | DRMO | 485 COMO | Shut Down | |
| 485 | GND | 485A | 485B | X | X | X | X | X |
* Prepare RJ45 connector and the communication cable, following the PIN definition and assembly order below, then insert the cable into the corresponding CT/Meter or BMS or DRM port of the inverter, and tighten the waterproof connector.
Diagram Description: The diagram shows how to connect the communication cable to the inverter, illustrating the different ports (CT/Meter, BMS, 485, DRM) and the RJ45 connector.
AC and Earth Connection
Cable size: 10 AWG (5~6mm²). Stripped length: 52.5mm.
1. Slide the cable nut and back shell onto the cable.
2. Insert the tripped end of three wires into holes in the female insert, then tighten each screw. Torque: 0.8±0.1Nm.
3. Screw down the threaded sleeve with pressure screw.
4. Screw down the pressure screw. Torque: 3±0.3Nm.
5. Connect the AC plug to the inverter.
6. Screw the ground screw (on the inverter) with a 4mm hexagon wrench. Torque: 1.5±0.2Nm.
Note: The cable size is 10AWG(5~6mm²).
Battery Connection and Overview
Note: If you use the lead-acid battery, please refer to the corresponding quick installation manual.
A: Power Connection Steps:
Press down spring until it clicks audibly into place. The fine wire strands must be seen in the chamfer.
Overview for connection:
1. After checking all connections are correct, turn on the external battery switch.
2. Turn on the grid switch.
3. Press the "Enter" key for five seconds to open the switch. The LED will be green and the screen will display the main interface.
Start Guide
Language: Select the language according to the need (e.g., English, Deutsch).
Date time: Set date time based on the local time (e.g., 2018-07-07 00:00).
Safety: The user can set the safety standard here according to different countries and grid tied standards (e.g., VDE4105).
Export Control: This function allows the inverter to control energy exported to the grid. User value setting by installer must be less than the factory value (e.g., User Value: 8000W).
Work Mode: There are 4 work modes for choice: self-use, back-up mode, feed-in priority, and force time use. Please refer to page 43 of the user manual.
RF control: RF control is an optional function (being developed) which can control designated load intelligently by consuming the surplus energy when feed-in power reaches a certain value. The function can only be achieved with Solax product "smart plug". For specific operation, please refer to "Smart Plug user manual".
Firmware Upgrading
1. Make sure the battery switch and the AC switch are disconnected from the grid. Unscrew the waterproof lid of the upgrade port by a straight screwdriver as the picture shows. Torque: 1.5±0.2Nm.
2. Insert U-disk with upgrade package* into the USB port on the bottom of the inverter. Then turn on the AC switch and the battery switch. The LCD will show the picture as below.
3. Press "OK" to confirm to update. After the upgrade is complete, please remember to turn off the battery switch and the AC switch, then pull off the U-disk, and screw the waterproof lid.
* Please contact our service support to get the update package, and extract it into your U-disk. Do not modify the program file name! Or it may cause the inverter not to work anymore!
