Connect and configure Deye/SunSynk/Sol-Ark inverters
Overview
Follow the steps below to connect the following inverters to SolarAssistant:
- SunSynk
- Deye
- Sol-Ark
- Turbo Energy
Step 1 - Select inverter
On the configuration page, select "Deye, SunSynk, Sol-Ark" as your inverter model.
Step 2 - Select connection interface
Select the USB port where your inverter is connected. If you have multiple inverters, you need to multi-select all of them.
USB to WiFi/RS232
A USB serial cable can be plugged into WiFi RS232 port located on the bottom
of the inverter. This is a normal USB serial cable available from most electronic stores.
USB to RS485
A USB to RS485 cable can be plugged into the RS485 port located on the inside
the inverter. This is an RS485 cable with a specific RJ45 pinout that can be purchased in our online store.
Deye/SunSynk/Turbo Energy 5K
Deye/SunSynk 8K
Deye/SunSynk 3 phase (Inverter firmware version before 2022-07-20)
Deye/SunSynk 3 phase (Inverter firmware version after 2022-07-20)
The inverter manufacturer released a firmware update which changed the port to read the inverter via RS485. An RJ45 splitter can be used to allow SolarAssistant to read the inverter while the inverter is also reading a battery via CAN.
Sol-Ark 8k
Sol-Ark 12k
Sol-Ark 12k Outdoor
An RJ45 splitter can be used to allow SolarAssistant to read the inverter while the inverter is also reading a battery via CAN.
RJ45 Splitter
An RJ45 splitter simply duplicates all pins in a port into two ports. It can be used to plug a CAN and RS485 cable into the single BMS/Battery port of the Deye/SunSynk 3 phase or Sol-Ark 12k outdoor.
When buying an RJ45 splitter, there are two typical products on the market. The one on the left works as expected as it simply diplicates all pins into two ports. The one on the right does not work as it doesn't simply connect pin 1 to pin 1, it changes them around as it's designed for ethernet use.
Note an alternative to a RJ45 splitter is to crimp two cables into a single RJ45 plug.
