Hi all,
I have searched and have not found an answer or recommendation for my specific scenario. Apologies if this is out there already but it is not clear to me and I have read and searched a lot! Appreciate any help.
With a DCDC Charger connected to the starter battery, do I need to chassis ground my house system negative busbar or is this accomplished already because the van starter battery is connected to the chassis at the factory ground connection?
All of my 12V loads, including the DCDC, have positive and negative leads equal in gauge and length going back to positive and negative bus bars that then connect to my 200AH house battery bank.
Obviously, the van starter battery is connected to the factory ground point between the front seats. Is this sufficient as a chassis ground for my house system as well? I've read having just one single ground point is important, otherwise my plan was to just connect a separate large wire from my negative bus to the chassis.
Some detail...
I have a Renogy 40A DCDC charger with positive and negative 2 AWG leads (oversized for the distance) between the DCDC and my van's starter battery. I will have a 60A MEGA fuse on the starter battery +. With the Renogy DCDC, a 12V ignition feed connection is required to power the unit. I have tapped into the Upfitter connection for this and have added a toggle switch to this wire in the dash to allow me to override the power of the DCDC as most of the time I will have it switched off when driving due to having solar and an inverter charger. Does switching off the power to DCDC charger impact using the factory grounding connection off the negative of the starter battery?
If I end up having to run a separate chassis ground wire from the negative bus, would adding my wire lug to an existing factory ground connection (like the ones at the tail lights) be acceptable?
Thanks!
