OK, so I recently posted a thread titled "Is this battery overkill."
I am going to be building a new RV shortly, and I was all set to get a VPX-Pro. Then there was a post by Carl Froelich (name used with permission) that made me really start to question what I was doing. Not that he was trying to steer me away from anything, but asking what I thought I was gaining.
He sent me his 5 Buss design, that after his explanation, made a lot of sense to me.
It seems people, including me, want all this redundancy (batteries, ECU's, Alternators, AHARS, etc) and then want to run it all through one single potential point of failure. I have read enough threads on the VPX (and other power management systems) to know that it CAN be a single point of failure.
So my question is WHY? (or why not). WHY NOT use circuit breakers / breaker switches? What do you gain by using the VPX-pro. Aside from speed controlled wig-wag (which is in the G3X) and flap position control, what do you lose by NOT using a VPX?
Carl's 5 Bus system made sense to me and seemed to be the ultimate in redundancy. I will try to post pictures...
Again, not trying to knock any product, I am trying to learn...
