Hi,
I have a Quattro 48/5000 running firmware 431. Off-grid, Venus GX , 3 X Smart Solar Lead Acid Batteries.
On three occasions the unit has shutdown with an overload error - in each case I am sure that there was no overload. The incidents have been about 2 weeks apart.
The second time that this happened, BOTH the temperature AND overload LED were lit.
The most recent incident (today) just the overload LED was on. This time I spent more time trying to diagnose the issue. I tried to reset the inverter using the remote console - using the "Switch" option (ie on the remote console turning the switch to off then back on) - doing this caused the overload LED to go out while the virtual switch was off - but the fault remained when it was turned back to the on position. Physically turning the switch on the inverter to OFF, then back to ON did clear the fault and the inverter restarted.
The inverter is about 4 years old. It may be just a coincidence, but the issue has only started since I installed the Venus GX and updated the inverter firmware to 431 about a month ago.
I am really concerned about this as we are often away from home for weeks at a time, and while I do get notified of errors, if I can't restart the inverter remotely, we could be in real trouble with freezers etc.
Any ideas what might be causing this issue?
Is there anything I can do to help diagnose the fault?
Is there any other way to remotely reset the error?
