Wiring diagram from battery to battery buss-bars for 2018 Reflection 303 RLS where ca

We had unit worked on and wiring was redone incorrectly from the battery to solar wiring. We need something to show repair shop how it should be please give us information
Thank you
Kathleen

Some pictures of what you have would help with your question.

If you give GD customer service a a call they can help. Have you vin handy. Also check over at the GD site as some there may have the diagrams you need or can help. There is also a GD solar face book page that may help.

Can you describe what the dealer did wrong. Solar wiring to the battery is fairly straight forward.

If the shop doesn't understand how it should work then I wouldn't trust them to fix it. The overall theory is pretty basic but a lack of experience is very dangerous.

Factory drawings probably don't match what you have, mine sure don't.

Having spent hours designing and wiring my own system, I am not sure how much help you can get form an online Forum, but, I will try.

Basically, the wiring is as simple as it gets: Positive to Positive and Negative to Negative, the only time a Positive goes to a Negative is in the case of 6 volt batteries that need to be wired together to create 12 volts.

In a typical Solar system you have the + and - wires coming out of the Solar panels, Depending on design, these are fed into a "Combiner Box" and you have two wires ( + and - ) which are fed down into the "Solar Charge Controller". The Solar Charge Controller has four wires Solar in ( + and - ) and Battery Out ( + and - ). The two wires coming from the roof are connected to "Solar in" and the two wires marked "Batt" are connected to the battery, that is it, it is that simple.

Now, because there are often several wires/cables that need to be connected to the battery and limited space on the battery terminals, then most installers will install "Buss Bars" between the Solar Charge Controller and the Battery, this is simply a connection point for all the heavy cables that need to be attached (electrically) to the battery, the buss bar is a thick metal bar with 4 (or more) bolts that allow the cables to all be connected. The insertion of a Buss Bar does not alter the path of the electrons, electrically, the Solar Charge Controller is still attached to the battery.

Here is a simplified Solar Wiring Diagram showing the components I mentioned as well as showing how an Inverter should be wired into the system:

Don't forget fuses or circuit breakers and a battery monitor!

My Imagine XLS 17MKE is pre-wired on the roof for solar. The wire used is 10 gauge. How do I determine what the maximum number of solar wattage the wire will handle? I'm considering one and perhaps two 190 watt Go Power panels. In your research what was your best online resource for solar information?

It's the amperage you have to watch. Amperage melts wire! Watts is calculated from voltage and amperage so changing either affects wattage.
W=V × A for a simple system.

10g is generally good for 30 amps, but note long runs and pushing the limits will spend the energy on heating the wire, not charging your batteries. So 30x12 = 360W maximum. Check the specs on any panels for their maximum amperage.
