Hi. I got the epever up-hi 3000 hm10022 hybrid inverter. It has a dry contact relay , that i can set "close" on a voltage, and then ",open" at a voltage.. its for starting a generator. Its many autostart diy kit out there, but i can't see whitch of them that is conrrolled with this type of...

Any of you tried to adjust the temperature probe on the qucc bms? Mine (1) is 8°c off. Used a glas with icewater, dropped in a digital temp probe to check.. its 4°c. Put the temp probe from the bms in,- it shows 12°c. I use the xiaoxiang app.

Hi. Android phone.. Any of you seen this before? Why has some of the words not enogh room? Like "remainin g" and i can't see the digits on "voltage diff" .. Is there a setting on the phone that can make room for everything on-screen? Besides that it works fine.. its the app from overkill..
