If the controller is to be used on a vehicle which has battery negative on the chassis loads connected to the controller must not have an electrical connection to the vehicle body.
Positive ground vs negative ground solar panels.
I ended up with a positive ground solar charge controller.
Common negative grounding is simply having all negatives linked to ground.
Safety v oltage transients and t h e sheer fact that they are required for some loads.
And all switching fusing control done on the positive side.
Originally the voltages on the wires were positive with respect to earth.
This occurs primarily because of moisture.
I find it kind of weird that positive ground charge controllers even exist since so many are used on rvs one would think a negative ground should be standard but i digress.
If grounding is necessary it must be completed on the positive line.
I am also powering some clearance lights with the truck trailer plug.
Common positive systems can be a massive can of worms.
Positive ground the positive terminal is defined ground.
As the negative terminals of different devices are all at different voltages in a common positive system.
Chassis or mechanical and electrical.
Negative ground means that ground is referenced to the negative terminal of the supply voltage.
They both relate to leakage to ground.
I have a not so typical question on charge controllers.
There are two types of ground.
A pwm controller switches on off modulates the ungrounded connection between the solar panel s in a negative ground system and or in a positive ground system and the battery.
The slide in camper has a chassis ground common to all the interior and clearance lights.
But before we address each of these it s important to understand the actual definition of ground.
This is called negative ground since the negative side of the battery is grounded to earth.
There are two distinct advantages to grounding the positive leg of a photovoltaic solar system.
I have it all setup to charge the house battery and have my loads set up through a fuse block on the load pins of the controller.
