Axpert Battery Voltage Spikes

Recommended Posts

Fault : Inverter Failure Fault Time : 09:35:41

Fault : Battery Voltage too high Fault Time : 09:35:45

Fault Fixed : Inverter Failure Fix Time : 09:36:12

Fault Fixed : Battery Voltage too high Fix Time : 09:37:22

Fault : Battery Voltage too high Fault Time : 09:37:30

Recurring messages till  Fault Fixed : Battery Voltage too high Fix Time : 12:19:59

I rebooted the Pi.It did not change the voltage keeps fluctuating between 55 and 63 as of 13:20.

Switching to grid gives me this error :  Fault : Bus Over Fault Time : 13:32:37

And back to battery Fault Fixed : Bus Over Fix Time : 13:33:09

Voltages are still in a fluctuation between 59 and 63.

Time for a repackaging and off to supplier ?

@flamegrilled something does not look right on the screen shots that you have , yes the batt volts does seems to jump but you batt amps is on 0 that is , dare I say , near impossible. Is the data in the screenshot form the BMV or the inverter?

In my setup I have a dual mppt that heats my cylinder and when it has reached the desired temp of 60 degrees it (the GW controller) changes to the second port and charges or floats the battery bank.

I had this like this for 6 months as I did not have an inverter connected to the bank.(another story)

The new old Axpert(2015 model) is also connected to this bank.

The monitoring device popped which I used to monitor Volts Amps Watts and Kwh's and caused the output of the DC to switch permanently to the battery output (or second HWC output) hence the fluctuation in the voltages experienced.

The older model mppt does not come with monitoring. I noticed this (via email) yesterday when I changed the license on ICC(Thursday evening).

I had a trial ICC license on the Pi.I did not notice that change in Hot water temp as the AC must have kicked in. My AC setting on the GW controller is 15 degrees less so as not to use Alternating Current.
