Solar Pkg / Factory Battery

Hi there. My Jay Feather Micro has the solar Pkg and I've gone off grid with it before. Today, I used it for the first time off-grid in a while, but it seemed something was drawing power or it wouldn't hold the charge. It would go from 13v to 10v with just the TV on. This has never happened before. Even using my JayCommand I can't extend my awning or slide, because there isn't enough power. I have always left the solar/battery on and never had this problem.

Thoughts and/or suggestions?

Could be the battery is bad. Charge it and see if keeps the charge. If it does, then look for a problem in the charge system or solar system not keeping up a charge.
Also, check that the connections are all clean and free of corrosion, including fuses, especially the one on the tongue.
I went Lithium as I was tired of worrying about battery state, running out of battery. Love the Renogy app showing me what part of the 100 amps I have left and how much the solar is putting back in.

I second checking the battery. It sounds like a classic case of a worn-out battery than will give a decent voltage (12.7-13.2v) when at rest but sees a huge drop in voltage as soon as it experiences a small load.

Did this happen at night, or in the day with full sun? There is no such thing as a factory battery on one of these, all dealer installed, so we don't know what you have, but I think the most common is an Interstate deep cycle 85AH. At 10 volts you would have used the full amperes, but as the others have noted the battery may be dying, so started with less than 85. As voltage goes down, every appliance draws more amperage, so it gets progressively worse. Do you have a 12V refrigerator? I would guess not, but one of those would pull the battery to zero overnight just on its own. You have the TV, the water pump, the Jay Command itself, any lights, you name it, so without a battery monitor it is difficult to see the draw.

Thank you for your responses. I will definitely check the battery. I did advise the dealership as well. Let's see what they say.

This happened during the day in full sunlight. I do have a 12v fridge and it stays in "off grid" mode. The water pump wasn't in, just the TV and fridge. Obviously aside from the JayCommand.

Looked into. They seem like a great deal. Which model do you have?

Curious, what are your system's specs?-
How many watts of solar, how many AH is your battery?
How old is your battery? What type?

The following is Furrion's specs for a 10cu ft. They seem quite "optimistic" to me, as a 100 AH lead acid battery shouldn't be discharged below 50%.

Typical Runtime (Off Grid Usage, powered by 100amp/hr battery)49 hours @ 77F (25C)31 hours @ 90F (32.2C)

I bought a Renogy premium kit and 100 amp standard Lithium renogy battery with bluetooth and a roof gland.

So far very satisfied except if you have no internet or cell connection the app does not work.

Even on cloudy days or during light snow got some charge back and never ran low but do not have or use 12 volts for microwave or TV yet. Install was simple once I figured out routing of the wire and where to screw down the panels. When the app works the bluetooth battery shows exact state of charge, use or charge rates, etc.

Some other brands like Chins now have bluetooth battery state for a bit less.

If you go Renogy get a referral from a previous buyer and get an extra 7% off. I like there warranty.

Wouldn't consider a 12v fridge with a single lead acid battery. I love mine but have two 190watt panels and two 100amp Battleborn.

There are many variables that could impact your experience with this.

1. As many have said, the battery might just be bad and not holding a good/full charge.

2. The 12v fridge will use a decent amount of electric. If you have not recharged with a generator, it may not be enough just from solar.

3. Taking the above comment, solar on RV's is not always efficient, this is due to the lack of angles to achieve best production. It is very possible that you only had a couple hours at most of good sun. With a single 190w panel it just may not be enough. With PERFECT sun it should recharge the single battery.

4. Weather and environment, clouds, rain, or being under trees (best places to camp) will greatly reduce/impact solar production.

Some thoughts, if it was or is cold and use of the heater, the 12v will reduce even faster as that fan takes a lot more than you would think to power. As others suggested adding a Lithium battery will double your time and actually charge a bit easier than a standard battery. Some cost more than others, this gets into a "religious type" discussion (around batteries). Battleborn, Renogy, Chins, AmperTime, etc. are all good brands and various prices/features. Chins/AmpereTime are basic batteries and can cost twice what a lead acid battery cost, but they do provide twice the power as a single LA battery at half the weight. Renogy and Battleborn are about twice the cost of Chins, offer some additional features that may or may not be beneficial to you or make financial sense.

At the end of the day if the current battery tests fine then I along with others on here would strongly suggest two Lithium batteries. At the very least one. They do cost more but they will/should last much much much longer than any LA battery.

If you decide to go down that route, please post again and let us know. I also suggest doing some searches on this forum as there is already a ton on here about that subject. But any of us will be willing to help as there are some questions that should be answered first.

Good luck and hopefully its simply a bad battery!
