1000W inverter upgrade not shown on control panel

[Arnoud64]

Recently we had a 1000W Xenteq inverter from our previous camper installed under the passenger seat by a well known VW Califormia specialist in the Netherlands. To my surprise I discovered that the power usage of the inverter is not measured and therefore shown on the control panel.
I suspect that the inverter is directly connected to the battery under the driver seat, and for that reason is not measured by the VW shunt. Will it help to move the minus cable of the shunt to the mass point under that seat?
And where can I find that mass connection point?

I've seen that pdf, but I don't see thet earth bolt in this picture. Or is it hidden under the carpet?

I think you may have to unbolt the seat from the runners and lean it onto the dash to see it.
I believe it is on the side and may well be covered by carpet.

Small but significant correction:
Will it help to move the minus cable of the inverter to the mass point under that seat?

Honest answer, I don’t know, but most other equipment, fridge, parking heater, roof hydraulic motor all have their own -tve wired to the chassis , not to the battery -tve pole.

This matters on the T6.1 which monitors each leisure battery separately. The T5/5.1 monitors the Leisure batteries via the Earth Shunt.

Hi,
Since a 1000W inverter can draw about 100 A of current from your battery it might overload the shunt, standard fuses or measurement range of the control panel.

So I guess they did it on purpose : connect it directly to the battery poles with a dedicated fuse.
