Advice - Measure and Monitor Inverter Battery Status/Voltage 24V

Hi All

I have a PSS SH3000 Inverter with 2 x 12V Batteries which I would like to monitor.

The SH3000 does not offer any external monitoring of alarms, battery status etc.

I would like to find some OH compatible hardware to monitor the 24V battery voltage to determine when the the battery level if running low and needs to be charged?

I have not been able to find any devices in my searches, so looking for suggestions?

Once I have an idea of hardware will have to look at what options are available to integrate into OK?

Any suggestions appreciated.


Actually now found the Shelly UNI, which looks like it will do what I want.
