Victron Multiplus Inverter repair: "low battery"

Hello  again, Nick here,

Have 2 older Victron Multiplus inverters, 12V/2500VA inverter chargers.
Initially bought to parallel them. Never was able to (the docs wrt  jumper config was wrong, gave up).

So, ok, I have redundancy. The first inverter stopped working after a couple of years, with a low battery led blinking.
Swapped over to the second inverter, and all was good, until recently, where I cooked it during battery maintenance (forgot I left array connected, and it smoked, still beating my self for doing this). A couple of caps at least, blew in the output stage.

Main Question is:
In general, is a "low battery" function implemented?What can I check for this?
Inverter has 3 boards.

The control/logic board has the eeprom with firmware, led indicators and a couple of discrete components that I should be able to check.

The intermediate board has the battery lugs, big dc busbars, fuse, circuit breaker, relays etc, and the 8 pin ic dc-dc? I'll get the ic type later.

The output board with the mosfets and drivers is sandwiched between the 2 toroids and I'd prefer to check that last.

Note: After cooking the second inverter, I swapped the control board the low bat inverter and still got low batt, possibly implying it's not the control board.

Swapped the intermediate board and all leds started blinking :-(

have stopped here,

Victron Greece say buy a new inverter. Victron Netherlands say we only sell, talk to a distributor.

regards,
Nick
PS I wish I knew about your Ozverters, Warpverters etc, 6 months ago.
