I am about to install a "Rover Li 20 Amp MPPT Solar Charge Controller" in my class B rv. It already has a RV Converter/Charger with a built in "Charge Wizard" (PD9245C – 45 Amp RV Converter/Charger) installed. Can I connect the Rovers outgoing battery cables to the Converter/Charger's outgoing battery cables? They both end up going to the battery.
Thanks, Dave

You can but it would be better IMO to connect to the battery unless you have a battery voltage sense wire for the rover.
Its about getting the correct voltage to the battery by avoiding voltage drop from small long wire runs.

So would we just connect the output from the solar charge controller directly to the battery in parallel to the existing shore power/alternator charging system? Will starting my generator harm the solar system?

connecting the controller directly to the battery is the way to go no matter how many other charging sources you have, they play well together.

Thanks, Dave So I actually have this same question/thought/idea. My charge controller and inverter are right next to each other and it makes no sense to me to run two sets of leads in parallel to the battery when I can simply run 8"-10" of wire from the CC to the inverter lugs and then rely on the already necessary large AWG inverter wires to carry the solar current to the battery. Basically the lugs on the inverter act as a buss bar. In my case I am building somewhat of a solar generator using two large Pelican Cases. Batteries in one case and electronics in the other. It doesn't make sense for me to run two sets of cables from the electronics box to the battery box when they both terminate at the same spot. |

So you have your CC going straight to the inverter and not to the battery? Then you have cables going from the battery to the inverter.... Am I right? |

The doubled up 4awg cables that Renogy supplies with the 2000w inverter will connect directly to the batteries (as they always should). It shouldn't matter at that point if I connect the charge leads from the CC directly to the battery or to the inverter, or anywhere along the length of those cables for that matter. It makes no sense to run a second set of wires when the inverter cables are multitudes larger than necessary to carry the 40amps (or less) coming from the CC. |

The lugs of the inverter are basically remote battery terminals once they are connected to the batteries with their appropriate cables.

Yea that's what I thought you were wanting to do...... I'm not sure it will work when it's under a load but why not all it could do is over load something....
Let us know how it works....
I just noticed you have a small system so your not going to be running a lot off of it anyway........
Best of luck....
