Supported Inverters:
-
Models supported (Deye/Sunsynk/Sol Ark and all re-brand hybrid inverters coming out of the Deye Factory in China)
-
Single/Split phase Low Voltage (40-60V Battery) 18kW/16kW/15kW/14kW/12kW/10kW/8kW/6kW/5kW/3.6kW/3kW
-
3 Phase Low Voltage (40-60V Battery) 20kW/18kW/16kW/15kW/14kW/12kW/10kW/8kW/6kW/5kW/4kW/3kW
-
3 Phase High Voltage (200-800V Battery) 80kW/75kW/70kW/60kW/50kW/40kW/35kW/30kW/25kW/20kW/15kW/12kW/10kW/8kW/6kW/5kW
- Battery using CAN Communication (to allow the RS485 Dongle to use the inverter BMS RS485)
- You need to have a 2.4GHz wifi network at the inverter with reasonable network coverage.
- You will need to run your own Home Assistant server (free software https://www.home-assistant.io/installation/ )
Powering the device:
- It can either be powered via the 12V output on the inverter (needs power cable) or alternatively **Note*,
- You need to have a USB type C phone charger to supply power
- Take care to only connect one power source
The DeyeSolarDesktop will give you a plug-and-play starting point to monitor your solar system https://github.com/tomatensaus/DeyeSolarDesktop
**Note: When powering directly from the inverter 12V supply please observe the correct polarity. The SmartDeyeDongle can take input from 5.5-36V DC.
The 8kW inverter supplies + 11, and – 12 on the function port (positive on pin 11 and negative on pin 12) on the new generation this is (RSD Positive 17 , Negative 18)
The 16kW inverter supplies RSD_out 12V on pin +15 & – 16 on the function port
The 12kW inverter supplies RSD_out 12V on pin +7 & – 8 on the function port (On the right)
The 3/5/6 kW documentation makes no mention of any 12V output, use an old phone USB C . Alternatively an old router power supply on the Dongle input takes 5.5V-36V
