Our LED's take very little power. I have turned them all on and the voltage on the solar controller hardly changes. I still use as few lights as possible, but it's the furnace fan (and to a lesser extent the CD player and pump) that takes the amps. If we do not have a good charge after a cloudy day, under trees, in a narrow canyon, we use the amp suckers as little as possible.

Thanks for the update on your solar install and experience. I too had the same problem with my batteries after I took delivery. Our first dry camp experience was in Kings Canyon NP shortly after we got our new Airstream. The solar panel was not able to restore the batteries on a daily basis. I added this to the list of warranty work the dealer was to perform upon our return. During servicing at the dealer, the batteries failed totally and fresh replacements were installed. Big difference! They now will hold the charge and allow us to conduct normal activities over most of a week of dry camping. Use of the furnace, as one post mentioned, will use up Ah faster, and shorten time between charges. I also concur that unless batteries are properly maintained on the dealer's lot, they will not have a long life. This includes topping off with distilled water as needed and keeping the batteries charged but not overcharged.

Instead of driving the AS I took the old batteries to the dealer and he replaced them with new Interstate SRM24's, which will be installed this weekend. They are each rated at 84 AH. Hopefully 168 AH will be enough for our 23 footer with 50W solar. We had no problem previously with our 20' with 40W solar, except we used candles most of the time to save energy from those 10W bulbs. In our new one we do use Lights one circuit only in the night assuming low wattage of those LED.
I guesss it is the learning process with new rig.
We are planning to go to Alask this summer

Can anyone confirm whether the LED lights on the Trimetric 2025 can be turned off when not needed? Trying to decide whether to mount in the bedroom of our unit or in the galley.

There is a button on the Tri Metric which switches the display from volts, to amps, to % of battery charge to off.

Even when off the Tri metric takes a small amount of current, 10 to 15 mA as I recall. Since it does take current even when off, on long storage periods the battery should be disconnected (good idea anyway) or the fuse removed from the Tri Metric. By long storage periods, I mean a month or so.

The entrance to our storage building is open to the south. I'm hoping that there will be enough light to 'tend' the batteries during storage. Time will tell I guess.
