New Reflection 260RD questions

I recently took delivery of a 2023 270BN. It has a non-lithium battery installed by the dealer. All I have done so far is put the trailer in my garage and plug it into the 120v standard outlet. The battery won't charge beyond 67.2% as read on the Furrion battery meter in the cabin. Is this normal? Dealer has no idea - yep, that's right, I can't get anyone on the phone that has any idea and GD customer service says not their problem cause the battery wasn't installed at the factory. No fuses/breakers blown. It is simply maintaining 67.2%.

Anyway, it's going back to the shop next month to be checked.

My understanding is the Furrion battery monitor has to be setup. The manual should be in the package of manuals you received on delivery. The setup requires discharging the battery then going through the setup process.
 
Getting back to the solar disconnect issue. I found a video that explains that the NEC (National Electrical Code) in the United States requires a disconnect between solar panels and a solar charge controller. You will find this at around 5 minutes into this video.

This would just seem like common sense to me.

I just checked mine and it’s the same at 67%. My battery voltage is at 13.18. I have a group 27 lead acid battery that my dealer installed. You will definitely have to calibrate the meter to get proper readings. I don’t like to run the lead acid battery down too low so I plan to leave mine as is. I will just keep an eye on the battery voltage.
I may add lithium batteries in the future.
Enjoy your new trailer.

Make sure the wet bolts are lubed before you pick it up. I suspect at some of mine were not.
Also, it's been a few years, but my large shade has failed in the down position. Have not decided on a replacement yet.

Thanks. I have it home now. I’ll crawl underneath and see if the wet bolts have been lubed. I do like these shades much better than the accordion style. If you find a better replacement please pass it along.
We sure love this floor plan!

While I believe installing a solar disconnect is a good idea, I don’t believe this regulation applies to a factory solar installation on an RV. My understanding is that the regulation applies to a solar installation that is tied to the electrical grid, and the purpose is to prevent solar power from back-feeding to the grid when the system is shut down for maintenance. Since the sole purpose of a factory installed RV solar charge system is to charge the battery, there is no direct tie to the grid. Installing a large solar array with an inverter could potentially change that.
 
Jomani, that’s understandable that you wouldn’t want to back feed the grid. To be honest I wasn’t familiar with the regulation until I came across this video. I would think if it applied to RV’s Grand Design would install a disconnect. It’s top of my to do list.

As far as calibrating the battery monitor I'm going to make that the dealer's problem - they're the ones that installed it and delivered it to me. I thought the battery was a factory install, but yep, turns out it's not.

Do you have a solar inverter installed in your trailer?

Our trailer came with a 370 watt solar panel and 50 amp Furrion charge controller. I’m not familiar with your model. You may have the smaller solar panel and 25 amp Furrion charge controller but the setup should be basically the same.
My dealer did a basic PDI of our unit. I was on my own to learn about the solar,TPMS and Compass Connect.
I have wiring for an optional inverter but none installed.

I caught the fact that the battery monitor was not calibrated during my PDI - I noted it and when I inevitably had to bring it in for some warranty work, they took care of it - but you can just use battery voltage and an indicator of charge left - they will be accurate when not on shore power though

12V Lead Acid Battery Voltage: Battery Capacity (Percentage):
12.73V 100%
12.62V 90%
12.50V 80%
12.37V 70%
12.24V 60%
12.10V 50%
11.96V 40%
11.81V 30%
11.66V 20%
11.51V 10%
11.36V 0%

Very useful information! That’s all I’ve done over the years. I keep an eye on my battery voltage with a voltmeter when not hooked to shore power.
So if I understand correctly the manual shows to discharge a lead acid battery to 11.36 volts then calibrate. Doesn’t this shorten the life of a lead acid battery? I suppose you could discharge it to around 12 volts then calibrate. Lead acid batteries are not to be discharged below 50%. This would give you a safe true accurate measurement of your lead acid battery capacity or better still let the dealer do it.

How ironic...a 12v battery at 12v is not good for the battery!
99% of folks don't know that and wonder why their battery doesn't last very long.
My AGMs seem to be fully charged at about 12.8v
 
To ensure the solar power ended before the controller, I installed a mini-breaker in the front of the storage area just before the controller. It is important to stop power from the roof solar panels even when you have a battery removed to avoid burning up the controller.

Here is what I did for the Solar Panel to Charge Controller disconnect. Bought a 60 amp DC mini breaker from Amazon. Now can kill the power to the controller before disconnecting the battery. Before I did this, my controller stayed powered up when I disconnected the battery. 260RD.
