Please assist with explanation of error code.  Tried google but could not find error code.  Thank you

Error code incorrectly stated

Did the Inverter shut down? If so, what error code is shown on the Inverter itself?
The app error codes unfortunately are meaningless.
Has the Inverter been restarted to see if the error comes up again?
Is this a new installation or is this a new error after having used it for a while?
What Battery Type has been used in Program code 05?
If User mode, what are the voltage settings? 
Is the Li comms link up and running if you are using Li Protocol?
 

I am away for the weekend, however will send someone to the house to check on the error code shown on the inverter.  Installation is 3 years+ old.  New error, never recorded before.  System has not shut down.  System ran on import from Eskom from 20:00 last night (when battery soc dropped from 100% to 0% instantaneously) and currently from PV with no import.  No charge going to battery from PV as the soc remains 0%.  Battery in USE.  Will get the voltage settings from the inverter.  Will update once I get feedback.  Thanks

Based on the info provided the battery circuit could be open circuit. Either fuse blown, error in the battery switch or the BMS switched off. 

Only my take based on the info available.

A blown fuse is highly probable seeing that the SOC dropped to 0%.
Can you still see any battery voltage on the app?
BMS would shut down if the voltage was out of spec.

Could also be a component failure on the battery side of the inverter or the BMS itself.

Spot on. I took the road of the items that one can check locally before removing the battery and inverter to be sent in for testing. 

I only saw the battery drawing 5W which could imply the BMS is drawing some power or it is just a stray reading as one can see at times. This could indicate some circuit in the BMS has component failure as you suggested. 

It still means taking a step approach to eliminate possibilities while testing on site.

When I had a blown fuse between the inverter and the battery the Sunsynk was reporting the battery voltage as being equal to the charge voltage (I do not use BMS comms), obviously no current was flowing.

In the period leading up to the fuse giving up the ghost, there were a few clues, like sudden changes in SOC, sudden changes  to charge voltage and current to name a few. These symptoms started more than a month before the fuse actually decided it had enough.

Thank you for all the info.  System was shutdown and restarted by a friend.  All working as normal.  Will investigate further when back home.
