2022 Jayco/Accolade GoPower Solar Controller

The factory installed GoPower solar system has never worked since we have owned our 2022 37K due to a bad cable between the controller and the Firefly system. The part finally came in and the dealer installed it however they didnít put in the correct parameters for the batteries so it thinks they are fully charged at 12.5volts and go into float mode. Can someone that has a functioning GoPower system give me the correct parameters? It would be greatly appreciated.

Thanks in advance.

Do you mean the 5 pages on the configuration screen? PM me your email and I'll screenshot each of them for you.

One thing you may want to check is whether theyíve wired the batteries correctly as they didnít on mine. According to the GoPower charge controller manual, Battery 1 is supposed to be for the house batteries and Battery 2 is the chassis batteries. Itíll fully charge Battery 1 based on the charging parameters youíre trying to set and then switch to charging Battery 2.

Doing some testing based on voltages (I drew down the house batteries by turning off the AC at the pedestal and turned a lot of 12V and inverter-powered items on), I discovered that the house batteries were being measured on the correct input on the Firefly unit itself, but were connected to Battery 2 on the solar controller. I then verified it by tracing wires to the battery terminals (red tape was on my house battery wires on both ends). So, it was charging my chassis batteries first and then charging the house batteries, contrary to the manual.

Also note that the battery levels and charging status shown under the GoPower section on the Firefly panel are for whatever battery is currently selected in the configuration screen. It takes a few seconds for the settings and battery levels to change after selecting the other battery.

I would be interested in what those settings should be also as I'm not sure how to tell if they were correct from the factory.

Unfortunately these were the same settings I had so itís something more than just settings for it not working correctly. With 12.4 volts in the house batteries the solar was only pulling in 7 watts during full sun on Saturday. I think the GoPower controller is bad.

I read this earlier and just had a thought.. If you havenít tested and ruled it out already, it could be the solar panel, not the controller. If it were me, Iíd remove the solar wires from the controller so I can test it while on the ground.

Since thereís plenty of videos on the topic, Iíll just provide this link as itís relatively short and to the point:


The Voc of the GoPower 190W (Overlander) panel is 24.09V and the Imp is 9.45A. Ref: https://gpelectric.com/products/over...-expansion-kit

It could also be a dirty or obscured panel, so Iíd at least take a look at the panel on the roof to ensure itís in good sun, itís clean and thereís no packing, protective film or anything causing lower output. If it doesnít test well on the ground, you may want to then test it at the roof to confirm whether itís the panel or the leads between them.

Iíd also recommend reconnecting the panels (and battery wires) to the solar controller using ferrules. Several of my wires were jammed in there, werenít making good contact and Iím surprised there wasnít a short or anything. I cleaned them up (cut and re-stripped) as necessary and added a ferrule to each one. Looks much more professional and makes a much more solid connection now.

Since mine was wired with 8ga wire (as read from the wire jacket), I used these ferrules:

And a crimper no longer sold, but came from a set like this one:

A few days after we got it home in January I noticed the controller wouldnít light up showing the panel was charging. I tested out the panel itself at the roof and it was showing 23 or so volts with mostly full sun and thatís how I discovered there was an issue with either the wiring or controller. The dealer replaced the cable going from the controller to the firefly system and that at least shows the GoPower system sort of running but itís weird. It will show 22/23 volts coming in but only 7 watts at its peak and it would show the batteries in float at 14.1 volts within the GoPower menu which seemed right but the Firefly system would show the batteries were only charged to 12.4 volts. I just donít know how it could be so different. I should have looked at what the Xantrex inverter showed at the time but didnít think about it thenÖwas really confused at the difference. My next plan of attack is to check the wiring connection under the junction box on the roof. Several have said Jayco didnít do a good job connecting the wires their so maybe thatís the case here. Not sure why it would show any volts/watts on the firefly screen tho if wires are messed up tho. If thatís a no go, on our last motorhome I installed 3 panels for 640 watts and had a Victron controller. It was a much better system and if I canít figure it out I will most likely swap the GoPower controller for a Victron.

For those with a working factory installed solar system - in full sun how many watts does your screen say it's receiving? In full sun, mine says about 30-40 watts and 20-24 volts. I feel like that's really low watts. Also, went up to the roof and found the positive was plugged in the negative and vice versa. I did'nt want to change that incase the backwards wiring was intentional due to it being reversed somewhere else, so the installer just reversed it on the roof to make it the same. Anyone know what would happen if you reverse plugged the panels into the solar outlet?

Just remember that for the power to be generated, something has to consume it directly (e.g, lights, furnace or 120V via inverter) or store it (batteries). At the top of the charge cycle, lead acid based batteries just donít charge at anything like the rate when theyíre lower (like at 50%). Also, if youíre plugged into shore power or driving, youíre now trying to charge with two sources cutting the current from your solar which does go to the batteries in half as they just canít accept it any faster.

I was seeing around 40 watts from my single GoPower panel during a very overcast bit yesterday. So, if your batteries are drawn down enough, nothing is directly consuming it, and youíre not connected to shore power or driving, that does seem pretty low for full mid-day sun.

Last week while in Orange Beach AL it showed 99.5 watts with the single stock 190W panel. That is the highest I’ve seen it hit this winter. Has normally been in that 30-40 range with the lower sun.
