Posted February 23, 20187 yr I was getting a bunch of these.Voltages hitting 62 volts.Panic sets in immediately.I will try to attach the ICC screenshots
February 23, 20187 yr Author This started this morning.The only changes I made was to add the perpetual key for ICC.Change battery setting for grids to 75 % SOC.It was on 80 %.
February 23, 20187 yr Author 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.
February 23, 20187 yr Author 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 ?
February 23, 20187 yr Author Had practically no load on the batteries today so the load was +-15 Watts. After adding a load,
February 23, 20187 yr This sounds very similar to that issue dockarl aka easilyboredengineer had with the standalone MPPTs.
February 23, 20187 yr @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?
February 24, 20187 yr Author 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.
