Possible problem with our batteries

Iím wondering if we have a problem with our batteries (and/or our charging system) and would really appreciate all your combined wisdom and information.🙂

Our two 6 v batteries on our 14 month old 2017 21 Escape use to read (until May this year) at 100% whenever we had checked them.
We have the 160 w solar panel on our roof. Since July, I have never seen a reading higher than 90% when checking 🤔

We just returned home from a four day trip to a Wisconsin State Park where we did not have any hook ups. The weather was colder than expected with evening lows of 34 degrees Fahrenheit and daily highs in the mid to upper 40s. It was overcast and cloudy almost the entire time and we were in a shaded site under tree cover from Thursday morning to Sunday noon.

Besides the fridge running on propane, (since Wednesday, the day before we left) we used things requiring battery power very sparingly:
* Just one LED light turned on for one and a half hours to a max of three hours each day
* The Water pump for just a few minutes a day to flush toilet and wash dishes
* Hot water heater put on three mornings (turned on for just for 20 minutes and turned right off)
* Two iPhones plugged into a usb outlet for Thursday night only
* Our propane furnace for three days set to run at 62 degrees for 11-13 hours each day
* NOTHING ELSE...... The inverter was not on and because of our concerns, never turned on.

I recorded detailed battery readings at different times on each of these days (in case that information is important in order to analyze things) but the short story is that on our first evening there (after running the furnace for two hours) our battery reading at 7 PM was 81% 12.6. (Our usual max reading hasnít been 100% for awhile (just 90%) so we were down 9%

As the weekend went on, our readings went lower, and lower. They did not recover during the day and by Sunday morning, our reading, with such minimal usage, was down to 65% 12.3 Since it was only going to be a high of 42 degrees and rainy, we were worried about our ability to stay inside (and have some heat and lights &#128563 so we packed up & left the campground a day early.

I realize that we were in the shade and under trees, but does this seem normal? From what I have read and have been told, I think we should have had much better readings on the battery based upon what we used. And possibly should have been able to run the microwave for two -three minutes a day or been able to have the furnace running and lights on for longer periods of time...?

Our reading this morning (parked at home now since Sunday) is ď90%. 13v .3 amps floodedĒ

It sounds like the batteries are ok if they ran the furnace blower 12 hours a day for 3-4 days. Did you try plugging into Shore power at home to see if the batteries get fully charged? If they do then it points to your solar charging having a problem.

We have experience a similar thing. We have two panels on the roof. In clouds/fog, the batteries drop quickly, even under relatively small loads. They are now 2 years old. When they were new, they stayed at 75% or better, no matter what. We were told by Reace that the 90% is "normal" for the controller reading, even if the batteries are fully charged. Ours sometimes shows 90% even when we are plugged in. The good news is that the batteries have always done the job.

At the two year mark, we are looking into alternatives. AGM would be okay but what we'd really love is to go all-out and replace our flooded batteries with lithium. Has anyone done this? I know it's expensive but we live full time in our rig and it would be worth it to us. Is it as simple as swapping batteries or does lithium require a new controller?

I notice you say "under trees and some shade, in Wisconsin, plus it is now October with low sun angles.

This is almost a worst case scenario for solar. For example, in Denver, mid-January, my 150 watt portable will put out 21 watts at noon when placed on level ground in full sun. Add in shade and I would expect almost nothing.

I would agree that a constant daily drop in battery % charge is "normal" - unfortunately.

One solution would be a portable panel that can be moved to a sunnier spot and aimed directly at the sun once or twice per day. Again, my example, going from 21 watts when flat, I could get 74 watts when aimed. A good % increase. But also note that I'm a long way from 150 watts, only obtainable at noon on the equator!

I've been using AGMs since my trailer purchase in early 2015 and enjoy all the advantages. But... Unfortunately they can't make power.

And like you, would love to upgrade to Lithium for additional advantages - but again, to get power out you need power in. Nasty, pesky laws of physics!

I think the GoPower manual stated 90% is full charge.. We had that on our trailer sometimes... it would take a few days of solar (2-3 hours a day) to get to 100% from 90% .. or I think it's a little quicker if we plug in to shore power..

I don't see anything unusual in your situation. As others have stated, clouds, shade, etc can cut down the solar panel output to almost nothing, and running the furnace it probably the heaviest draw (other than the inverter).

Since 12V (around 50%) is about a low as you want to go to get a decent life out of your batteries, you might have made the last day. In any case, after a string of cloudy days when I didn't have the option of going home early, I connected the tow vehicle & ran it for a couple of hours. Not the most efficient way of charging your batteries, but since I don't carry a generator, it was an option.

The GoPower will read incremental percentages up to 90% and stay reading 90% until it reaches 100% power. If it reads 90% you MAY have 97% in the battery, or just 92%. The battery monitor over my refrigerator will show all the lights on.

I have noticed that if I drive late into the evening, a few hours after dark, then my GoPower will show as low as 78%, sometimes 86%. I assume it isn't getting much of anything from the truck alternator and may be using some power on the trailer lights as I drive. I haven't worried about it but if I drive late in the evening and then camp in a wooded area I wonder if it will ever recover to near 100% during the day. I tend to try and choose the more sunny spots if I have a choice in camping sites.

Even in Baja in winter there's quite a difference between flat and inclined. And more difference when pivoting and tracking the sun.

Lot's of reasons to have flat panels but you're never going to get the maximum out of them. My 100 watt panel does the job for me but if I need more output I'll be getting a lightweight panel and using it as a portable panel, placed for maximum output.

Your trailer outside lights (other than the porch) are powered by the tow vehicle, not the trailer's 12V system. If you are running the refrigerator on 12V, that would do it, otherwise, there isn't much that would use that much amperage...
