I have 2 different sites with the same error on both.
Both systems have 2x Multiplus 5kVa in parallel.
Battery connected is BYD B-Box 10.24kWh.
Since installation both systems have been giving Error 17.
Both systems were updated to latest firmware 2624431, and then loaded with older firmware to try and correct the error.
On both systems the comms cables have been checked and replaced with new cables.
Has anyone had similar problems and if so what was your solution?
Thanx in advance.
