Renault TCab Owners/Drivers/Maintainers/Etc - Inverters

Looking to install an inverter in a 16 plate TCab, so I can carry a microwave, various chargers and sundry items that will make life a little more “comfortable “ during the tramping week.

I’ve read in a couple of places that there are points under the bonnet preinstalled from the factory for such things, although on quick inspections I haven’t yet found anything.

Could any owner, operator, maintainer, driver or dogsbody confirm or deny this please?

Looking at 2500-3000w.
