FoxESS Community - Owners & Installers Forum

Hi All,

I am the new owner of a H3-15-Smart inverter and Battery.
I am currently running a home assistant integration by "nathanmarlor" but there is not control for the export limit.
To change the export control I have to set the setting locally at the inverter control panel.
Is anyone able to educate me to what modbus address I might be able to control the export limit on?
I am currently getting charged to export to the grid during the day but need to change the export back to a higher number during the night.

Thanks All

You might have to do some test reads to see what the H3 Smart is using, the original specification used 41012, whereas the latest spec uses 46616

Thanks for pointing me in the right direction Dave
I'll try modbus poll today and report back

Unfortunately no luck on 41012 & 46616, I get illegal Data Address. I did try and scan a bunch of other addresses but dident see anything that resembled the export limit setting.

Make sure you try them as both input and holding addresses

Hhhhmmmmm, thanks Dave, I will have another go tomorrow
