This video shows the external unit of a mini split ac mounted in a near horizontal position underneath the van. I was under the impression that this was not possible without disassembling the unit and remounting the compressor. Perhaps that's what this person did, but doesn't detail it in the...

Dzl - I think some info from RandyP in the link in your previous post answers the question: Looking back through my controller manual it also calls to keep negative and ground connections separate, if this is referring to the same thing:

Well Dzl, with grain of salt taken, your replies are VERY much appreciated, thank you! ?‍♂️ This definitely helps get me closer finalizing the method I was leaning towards. Those resources are great, I had not come across RSD Academy. I love the classroom style explanations. I did notice the...

Thanks for this info Steve_S, it's definitely informative even though I'm still left scratching my head for most of the details in my questions and wiring/fusing issues. Still researching... Zil, it sounds like you recommend connecting neg bus bar to chassis, and inverter and controller ground...

Thanks for the input guys. Instead of the negative bus bar I'm going to connect a battery negative to the chassis since I have just enough cable for that distance. I'll ground the inverter and charge controller to the aluminum wall behind the wooden panel board via through bolt. As far as the...

Sorry maybe that was worded poorly. I have just enough 2/0 cable left to make a ground connection from the negative terminal on the lowest battery to the vehicle chassis. I don't have enough to go from the negative bus bar as originally planned, but running from the battery negative terminal is...

Grounding seems like an important issue for all us DIY'ers who are not electricians and start tinkering with electricity, and it has been the hardest thing for me to get a clear answer to, at least for these types of mobile setups. I have assembled a 24v mobile system based on the blueprints...

Ah yeah! I remember now reading about having only one ground to vehicle chassis point to avoid ground loops (which I haven't gotten around to understanding), so grounding the inverter and controller at other separate places would break that rule. Hence the ground bus bar in the controller...

Thank you for that analogy, that really helps in wrapping my head around the concept. I also would like to understand this better - you replied that an actual stake in the ground should be bonded to the vehicle chassis if we're going to work with power tools off the inverter while outside the...

I took the " vehicle's safety ground" to mean the connection to the vehicle chassis... and " For the majority of installations, the negative battery conductor (black wire) is bonded to the vehicle's safety-grounding conductor (green wire) at only one point in the system" to mean that the...

Quoting first response in a google search: " Essentially, a "ground" is an electrical connection to a common return in circuit. In automotive terms a ground is a connection to the body or other metal surface of the vehicle. The body is connected to the negative terminal of the battery. " I...
