Thanks Mike. We are heading to AZ after the holidays.

Beautiful! A very impressive install. Congrats.

Wow, what a setup! Solar powered AC in a truck camper :)

I have been pondering solar powered AC and was looking into these batteries.

I was reading a blog about these....A RVer with a sprinter used two and modified a mini split ac with heat pump.

There are some using electric car batteries in RV applications. Youtuber "beginning from this morning" is doing a nissan leaf install into a bus. Pretty impressive.

Mini split is an excellent way to go if you able. They seem to be more efficient.

As far as solar powered AC the challenge for a TC is the limited panel real estate on the roof. My system can run the AC for over 5 hours with 100% compressor duty and no solar. With solar charging and compressor cycling the range is much longer. Still though the panels don't charge at night and practical day to day use will require a charging strategy that will limit use to account for sun and recharging time.

What is interesting is he is running a 240V mini split....the only way to get a heat pump.

I will look for that Youtuber....thanks for the info!

Congrats on the finished install and welcome to the lithium side of life. Nice power to weight or lack of battery weight.
Once you get feel for the system and and it becomes something just running in the background you'll forget that you're running off batteries. Plus the added bonus of not worrying about topping the batteries off and still having power without the voltage drop.

Enjoy :C

Thanks, yes quite different discharge curve and characteristics. Big loads barely sag the voltage and it seems to run forever in the voltage sweet spot.

Yes, quite different. I've had mine on the morning of the 3rd day down at 28% (140ah) make a 12 cup pot of coffee, use the microwave for 5 minutes making breakfast, inverting at 12.4. Then watch the sun finally comeout and charge the bank back to a 55-60% and think a couple more days of sun like that and the bank will be back near full again. No worries.

Thanks guys!

Looks like a very very nice install! Great job and thanks for sharing.
