Hey thanks for the reply. Using ICC but in icc the battery level was still 43% no problems. The inverter was showing E04. Battery cut off is at 46v so wasn't there yet?

Hey Did anyone manage to solve this issue? I just installed 3 x Pylontech U5000 batteries. Just got the same error on 1 battery. As soon as I hit 49v. The other 2 carried on as usual. I had to turn off the batteries and reboot and everything was fine. Any idea?

Thanks guys much appreciated, iv tried a s10 and an iPhone and an iPad. Maybe an issue with new Bluetooth protocols I’ll try use an older phone maybe. To be honest I think I’m should just order the cable. ill keep you guys updated thanks

Hi guys Iv been reading through a couple of posts and everyone seems very helpful. Please could someone help me with a problem I’m having. I have an Axpert 5kva inverter with two banks of 4 x 200ah batteries @ 48v. From what iv read the axpert has terrible battery monitoring features so I took the advice and purchased a victron bmv 712. On first connecting there was a firmware update that started and couldn’t finish. Went to 10% then 6% then 50 % then failed. Now the unit just says ft200. I have tried all the trouble shooting options of removing and installing victron connect, unpairing unit. Unplugging for 10 min then trying again. Even tried on my iPad and my Samsung got the same issue. How the hell can we get this thing working 🙈🙈🙈
