flamegrilled Posted February 23, 2018 Share Posted February 23, 2018 I was getting a bunch of these.Voltages hitting 62 volts.Panic sets in immediately.I will try to attach the ICC screenshots Quote Link to comment Share on other sites More sharing options...
flamegrilled Posted February 23, 2018 Author Share Posted February 23, 2018 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 %. Quote Link to comment Share on other sites More sharing options...
flamegrilled Posted February 23, 2018 Author Share Posted February 23, 2018 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.

flamegrilled Posted February 23, 2018 Author Share Posted February 23, 2018 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 ? Quote Link to comment Share on other sites More sharing options...
flamegrilled Posted February 23, 2018 Author Share Posted February 23, 2018 Had practically no load on the batteries today so the load was +-15 Watts. After adding a load, Quote Link to comment Share on other sites More sharing options...
___ Posted February 23, 2018 Share Posted February 23, 2018 This sounds very similar to that issue dockarl aka easilyboredengineer had with the standalone MPPTs. Quote Link to comment Share on other sites More sharing options...
PaulF007 Posted February 23, 2018 Share Posted February 23, 2018 @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? Quote Link to comment Share on other sites More sharing options...
flamegrilled Posted February 24, 2018 Author Share Posted February 24, 2018 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. Quote Link to comment Share on other sites More sharing options...
