the seller wrote to me that the inverter has been repaired, he sends it to me next week, last error that gave powering even with the network only, the battery voltage was high. I'll ask what pieces he changed

Today ONLY BATTERY, no grid , no PV Real Voltage battery 51V ... read ok Inverter 67V!!! real FV voltage disconnected... inverter read 612,8Vdc 6400W .. incredible!!!

yes it is a strange mistake, in conclusion: - the inverter goes into error 51 with the photovoltaic connected together with the storage with and without load at the 230V output -FV connected + mains input without batteries does not go into error 51 with and without load 230V -Fv disconnected, with accumulation connected + mains input works regularly with and without 230V load -Fv and mains input disconnected, with accumulation connected it works regularly with and without 230 V load -From Error 59 when I connect PV with inverter off, storage connected without / with grid connected, the PV string voltage was 255 Vdc Bus voltage with batteries connected on 430V and internal temperature of about 40 ° C, without batteries the voltage remains on 360-370V and internal temperature of 20 ° C

40-42°C inside at Inverter Today error 51 with solar first , yesterday no F51 used battery recharges with photovoltaics no utility.. Without photovoltaics it works regularly, input mains works regularly If I use the mains battery charger at night it works regularly. if I use the batteries to supply the 220V the inverter works regularly. Before I ship the inverter for warranty repair, I want to understand what causes it to go wrong to help you out.

I have an Axpert Vm3 5KW mppt 120-450V, 16 batteries of 100A AGM , PV 1500w 270Vmax. I use it in parallel to the mains, my problem started 3 days, at 12:00 12:15 PM it crashes with error 51 every day at the same time goes into error, reset works for 24 hours. I reloaded the firmware, panel control 2.61, main unit 91.20, here it is winter and the winter temperature is at 40-42 ° C I discovered that I have two batteries at 10.8 V, I disconnected them and today it did not give me plus error 51. now I have changed two batteries and tomorrow I will repeat the test

Hello peole from italy with Axpert VM3 error51!!! from 3 days but I think I have resolved
