I have DSDP 2000 model. I’m wiring in a Victron 1200 watt PSW inverter to solely feed a JC refrigeration conversion fridge. I have two questions; #1 does anyone have a clear picture of the battery connection placard, that shows cable layout of battery cables for a 99-2001 Dutch star diesel?
#2 my setup consists of 2 12V batteries wired for 24 volts on the left side of battery tray for engine. There are 4 6V GC batteries on the right side of tray for house. Positive terminals on the right, front to back and second two side by side.
Main hot cable comes off front battery + terminal on right. Main ground comes off rear - terminal of rear second set of batteries back left battery. Are these where I place the negative and positive wires that feed the inverter? I hope I explained it clearly

I haven't heard of any RV chassis that uses 24 volts for the starter .

My 99 F/L has two chassis batteries but they are wired to provide only 12 volts to the starter, and the rest of the chassis systems,
Having the chassis 24 volt and the RV portion of the coach 12 volt, would be a wiring nightmare .

This, ( photo ) is the placard on my battery tray for the 4 X 6 volt batteries , but it is only a rough representation of how the cables should be attached .
The actual hook up is different on the batteries themselves .
I can take a photo tomorrow and post it , but if your coach is like mine ; with multiple battery replacements over the years , yours could be different .

If your battery placement , and cable hook up, matches the placard , you can see the diagram shows an inverter positive hook up , then attach the negative side to the same terminal as the main chassis ground.

I agree with Skip here too.

Call your local Victron Energy sales guy for the best answer, but your 1200 watt VE inverter should be wired to the mains on your house bank, with an inline ANL fuse adequately sized for your application and a shutoff/disconnect close to the VE Inverter.

Also, JC Refrigeration offers an 88 watt DC compressor modification that runs (obviously) on 12 or 24 VDC, eliminating the need for that added inverter.

My mistake, two 12V to starter. Your placard is just like my setup. Thanks for pic

I was tempted to go with the 12V compressor however, when queried, JR said the 120 V compressor was quicker to get cold although both will get you there, the 120v is quicker.
I assumed that’s how inverter was wired but wanted to make sure
