Hey folks.

Getting Solar PV tomorrow with a Sunsynk 7kW hybrid inverter and two Sunsynk batteries (exact model not clear yet but they're 5.32kWh each)

Been looking at various options for local control but wondered if anyone had experience with specific hardware available in the UK.

Ive seen Solarman "dongles" mentioned and various pieces of cheap MODBUS / RS485 / CAN hardware. I've also read about using ESP32 with ESPHome or similar but that route provides less data so I'd prefer not to go that route.

I suspect the install will come with the first-party WiFi dongle but I intend to rip that out as I don't want/need the cloud or remote features. My understanding is that the batteries will connect to the CAN bus or RS485 so at least one port will be occupied.

I can get WiFi to near the inverter and maybe ethernet with some effort, I'm not sure there will be a plug socket to power something like a raspberry pi since it's going in an outhouse unless they decide to fit one, but I guess that's unlikely as they'll want to minimise effort and cost.

Anyone have experience with these Inverters and home assistant and which hardware providers the most control/data?

Thanks

Hi i am using Deye inverter which is basically the same as sunsynk, but i have 3p 12KW, so there might be differences.

battery BMS has dedicated RJ45 port (which has both RS485 and CAN) but there are also other ports intended for modbus and multi- inverter setups

Easiest way is solarman, but if you'd like to avoid their cloud, etc probably https://kellerza.github.io/sunsynk/
i am using custom solution but it's essentialy esp32 + custom integration

Deye/Sunsynk

Take control of your inverter.

Hey Thanks for the response. I didn't get a notification for some reason 🙁 I solved it now ussing Kellerza's addon and a USR-W630. I'm going to contribute some documentation back to Kellera's site since it's lacking detials on the setup.

The requirements for me were that it's fully local and has frequent updates. I now have updates every minute for most entities and every 5 minutes for others; I could make it more frequent but it's a lot of data.

It's been running for a couple of weeks now and works beautifully.
