I’ve created a YAML-based integration for Sigenergy hybrid inverters over modbus:

Hi Andrei,
My new Sigenergy will be installed end of this month and I’m trying to find as much as possible info about integration with HA.
Please to find you here
Good to see this here, one of the options for our solar system is Sigenergy. Are many people using this integration? Just curious if it’s reliable and working ok for multiple people, given how new it is.
Thanks for this integration. I had a Sigenergy inverter installed the other day and so I have installed this version of the integration:
and it’s working nicely.
Battery is yet to go in (July) but I have managed to use the data to set up EV charging with excess solar PV using an API push to ChargeHQ.
That’s handy as our system has an export power limit of 5 kW, while the inverter is 12 kW with nearly 15 kW of PV.
This integration inserts a lot of entries in the database, because the data comes through every second or two. My PostgreSQL database increased in size by around 1GB with a history length of 8 days. The entity sensor.sigen_inverter_power_usage has 300,000 entries, almost 40K per day. sensor.sigen_consumed_power has 160,000 entries, almost 20K per day.
I’ve just put a bunch of excludes into recorder to prevent the data being recorded. I would have edited the integration file directly to stop them being bought into HA at all but then I would have to make changes every time the integration is updated.
Hi,
Looking at getting Sigenergy battery. Do the either of the integrations expose the usage of each of the circuits through the gateway or is this data available through the app.
Trying to work out if I add additional circuit monitors while I have the sparky here.
Thx in advance.
Hi,
I’m just getting a sigenstor and gateway installed too as we have a very unreliable grid connection, and also curious if this integration exposes the gateway status? Ie will it say when in island more or not?
We’ve got another 18kw solar system downstream of the gateway on another building (hence tricky to wire direct to gateway) and I’m hoping I can use this integration to read when the house is off grid to prevent the other inverter (a solax G4) from exporting and potentially overloading the sigenergy system with nowhere to dump excess power.
I can already use HA to control the solax system settings over modbus, just need the trigger to set the export limit value to zero…
Cheers
I’m using Sigenegy2MQTT add-on but I expect it will be the same for the Modbus integration. These are the sensors I have for the grid energy sensor in the gateway:
thats great, thanks.
‘Grid Status’ is clearly the parameter I need there, so just need the extra modbus-eth converter to arrive tomorrow and I should be good to play around on this.
