I have been thinking about chassis grounding my van based RV system. You can see the electrical drawings here.
I plan on having alternator, solar and shore power. The inverter (Victron Multiplus) will take care of AC neutral/gounding. I am connecting to the vans electrical system which does tie the battery negative to the van chassis.
The alternator DC-DC charge controller (Victron Orion TR Smart) come in an isolated or unisolated version. Is there any real reason to keep my house battery negative rail isolated from the van chassis ground?
Are there any upsides or dowsides to either scheme? The isolated DC-DC controller only cots $40 more and I can always bond the two grounds together if I decide to do so later.
Opinions? Suggestions for further research?
24V Van System Drawing. Get your overripe tomatoes ready!
After months of pontificating, I have finally pulled together the electrical design for my RV conversion. Let me know what you think. This is my first version and I would much rather fix as many problems at the pixels on a screen stage as I can.
