Hello everyone!! Thought Id compile my experience with the 71.93 firmware post update

My setup:
2 x Kodak 5K Axpert King
Parallel with USE on Slave and PYL on Master
Firmware 71.93
Display 02.49
7 x US3000 3.5KW
 
 
1.  When the batteries are fully charged on setting SUB, (error 61 if I recall correctly and this means battery full) pops up on the display and the inverters only use power from the UTILITY AND NOT THE SOLARS for LOAD.  I have settings SLB UDC (Solar for load then battery - Utility dont charge Battery) - (This issue was not a problem with prior versions of the firmware). I switch them to SBU the error disappears switching the Solar back online
 
2.  Later at night when I want to switch the Inverters back to SBU (from SUB setting 2), they stay on UTILITY and don't go to BATTERY - I have to power cycle the inverters to kick them out of UTILITY.  This issue occurs late afternoon when or night when no Solar power is generated.  The batteries SOC are still fairly high - around 70% to 90%.  This also occurred today for some reason while Inverters were on SBU and when i checked on them late afternoon, they were back on Grid (Still on SBU) with batteries around 80% to 90% SOC
 
3.  After upgrading to 71.92 and 71.93, the watchpower 1.13 software doesnt pick up my inverters.  The "firmware software updater" however picks up the serial/USB port without problems in order to perform an update. If I plug another inverter (example the 3kva) to the PC it also picks up fine on the winpower software.  Is there a new version Im not aware of?  Other software possible better?
Note I have tried different cables and PC/Laptops to check the issues and the above is true, though its straight forward that the issue is not PC or cable related
 
4.  71.92 had an issue on setting 29 set to 47v and cannot be changed - (Inverter set to Pylon as stated above). Starup load for example a pressure pump will drop the voltage below 47 volts (with other load also present), therefore kicking the inverters to Bypass.  I have updated to 71.93 and the issue seems to have gone away.  The issue still remains though that I still cannot change the setting 29 to a lower voltage from 47v. I want to set the BACK TO GRID (setting 16) to 47 volts, therefore the Bypass (Setting 29) should be surely alot less?
 
5.  Do the Inverters require so much power when running on SUB? I have an ammeter on the Mains and it reads 2.4 amps for both inverters (no other load except inverters)? Internet Research stated around 40watts per inverter and even with a 0.5 power factor when inverters are on idle it still does not make up the 1.2 amps per inverter? Is this normal?

6.  Im guessing the solution to most problems above is to get a Raspberry Pi 4 with ICC software? I see its an issue to get the Pylon Comms cable which is where Im stuck at the moment with - out of stock nationwide

Thanks advance for the assistance!
