Haydn Posted July 18, 2018 Share Posted July 18, 2018 Morning All, Have just started a revamp on my battery situation and left 4 105ah to keep the 3 4kw axperts running while new cabling etc done. However losing all power and error 56 comes up. Anyone know what the battery open connection is? Cheers Haydn Quote Link to comment Share on other sites More sharing options...
Youda Posted July 18, 2018 Share Posted July 18, 2018 (edited) Hi Haydn, I'm not sure whether you are really asking, or it's just a joke, but error 56 (battery connection open) means that you've disconnected the battery from Axpert. If you have all the cables back, restarted Axpert and it's still reporting E56, then check the battery fuse or MCB. Also, if the battery is deply discharged, so the voltage is way bellow the acceptable range, then it might give you E56. In that case, reviving the battery using an external charger will help.

Gnome Posted July 18, 2018 Share Posted July 18, 2018 The Axpert has a fuse internally also, which could be blown. Quote Link to comment Share on other sites More sharing options...
Haydn Posted July 18, 2018 Author Share Posted July 18, 2018 Thanks guy's Not kidding cabling from the 4 x 105ah batteries to each of the battery disconnect are all good. Voltage of batteries under load all around 12.2v ( battery tester with load ability ) Will check fuses this evening. would 1 fuse out of three be able to create the 56 error ? seems logical as they are in parallel.

Gnome Posted July 18, 2018 Share Posted July 18, 2018 No offense but are you sure you know what you are doing? Shouldn't the voltage be 48v for the Axpert 4kW? (thus series not parallel) ___ 1 Quote Link to comment Share on other sites More sharing options...
Youda Posted July 18, 2018 Share Posted July 18, 2018 Haydn, just check the voltage directly on the battery input terminal of each Axpert unit and you will find out. If there will be the same voltage on all three units, then I would check that internal fuses, just like @Gnome noted. Quote Link to comment Share on other sites More sharing options...

(thus series not parallel) Oh yes, this is definitely worth to check! Anyway, please check the exact type of the units you have, and the voltage they require before any further rewiring, as I'm starting to feel some smoke Quote Link to comment Share on other sites More sharing options...
Haydn Posted July 18, 2018 Author Share Posted July 18, 2018 no offense taken, Gosh gee whizz, testing each battery separately to also check on balance. 4 x 12 = 48 will also test at the Unit and the batteries are in series and the units are in parallel Youda 1 Quote Link to comment Share on other sites More sharing options...

I can't be certain. But my reading is that fault code 56 is not automatically sent to the other paralleled machines. So each of the machines must have measured less than 30 V at the battery terminals. My guess is that your temporary wiring had some sort of glitch whereby there was enough voltage to run the electronics and processor, but not enough to actually run the inverter and power loads.
