FoxESS Community - Owners & Installers Forum

It annoys me when people ask a question on forums, followed by a flurry of responses and then nothing... because they have solved their problem but not then come back to the forum to explain what the problem was and the subsequent solution. So here I am, a little later than planned but here neverthe...

OK.. changed the first two comms cables for CAT5 straight-throughs and it made no difference..

Here's a video of the booting process if that helps..

Is it possible you might have used one of the new comms leads on those lower batteries? (i’ve seen a spate of faulty ones recently) Yep... most definitely..

OK.. so had a fiddle this morning... Went back to 4 batteries and rotated the DIP (on the BMS) back to 2 - booted it all up and got the same error. So, to try and do the isolation process properly, I'd need to revert to the minimum config which, I think is 1 x BMS and 2 * HV25 modules - correct ? On...

That makes a lot of sense (the triage process).. Will try that tomorrow and report back. Thanks very much

I had 1 x BMS and 4 x HV25 batteries installed and all has been fine for 3 months. FLush with the joy of "free" electricity, I bought and have now added 3 more HV25 batteries to the system this morning following (this post >> https://foxesscommunity.com/viewtopic.php?t=748 ) Now when I boo...
