SAJ Solar inverter

Hello, i’m using the Github elekeeper integration and it works great, the sensors values are right but i’m having some anomalies with spikes in values everyday around 00:00 or 00:05. maybe I’m using the vrong sensors in the energy configuration dashboard.

This are the anomalies in the dashboard


Whenever I remember I clean the values in the statistics but the anomaly apperars everyday around midnight
As new user i can only upload one image per post, I’ll try to upload a screen of my energy dashboard config, maybe i’m only using the wrong sensors in the dashboard.
Thanks in advance to everyone coul help to solve this little issue.

These are the sensors I’m using in the nergy dashboard.

Does anyone know if the register 8020H can also be used on an H1 inverter to sync the current datetime? The internal RTC of my inverter is slower than the real time, so I would like to be able to sync it by writing it via modbus. I sadly can’t find any documentation for the H1 inverter that confirms that this register 8020H is also writable like it is for the H2 and R5 inverters…

Nobody who knows or already tried it for a H1 inverter?

I am sure that there was a fork of the Component released by stanus74 but adapted only to the registers in common with the H1 series inverters, can anyone help me find it?

What route did you end up going? I am installing a SAJ H2 inverter next week, and I think AIO3 is very expensive for what it is. I have a bunch of ESP32 and Modbus adapters (like the one BenV linked) laying around. I thought it would be even cheaper and faster than the Elfin solution

Not sure which fork you are talking about, but you can also use my integration (over mqtt) from here: GitHub - h3llrais3r/ha-saj-h1-mqtt: Home Assistant integration for SAJ H1 solar inverters via MQTT
I’ve been using it for more than a year now without any issues.
This doesn’t require extra hardware and you can keep using the existing app.
You only need to bridge the mqtt server (or change directly to the your local one, if you don’t care about the saj app)

EDIT: attention, if you have the most recent AIO3 module firmware version (v1.212) it seems to be using an encrypted mqtt endpoint… This breaks the integration as we don’t know the encryption being used. (see Timeout error: the inverter did not answer in the expected timeout · Issue #3 · h3llrais3r/ha-saj-h1-mqtt · GitHub)
