Mabru out of Florida. They are well known for Marine systems which the RV shares a lot in common with. I've attached a couple of photos that shows the finished product both the compressor and blower

Give them a call Omar is very helpful

I did end up installing a small 12,000 BTU 12 volt DC mini split in my Sprinter. It only draws 35 amps and can run over 30 hours on my 912 Amp Hour battery bank. The compressor is mounted under the chassis of the Sprinter near the rear bumper and the blower is small enough to go inside one of...

I too want to eliminate the dependence on a generator. My battery bank is 1280 Ah. Obviously the problem is charging larger battery banks with solar. I've decided to go with CTEK Smartpass 120S coupled with their D250SE and utilize the vehicle alternator to assist in charging. With both CTEK...

Thank you for your reply and input... My alternator is 280 amps, but I plan on installing a 2nd alternator dedicated to charging the coach battery bank. I actually haven't received my RV yet. Its being built but the Generator option was $4K. I figure using these funds to build a better...

Is my math correct?: Generator outputs 30 Amps so 30 x 120 = 3,600 Watts (if one were using a generator) Alternator output 140 Amps so 140 x 12 = 1,680 Watts 1280 Ah bank: 1,280x12= 15,360 Watts (storing capacity) Total time to charge bank if totally depleted: 15,360W/1,680W = 9 hours

It's my understanding that an alternator will perform OK when output is 50% of its capacity. If it's a 280 Amp alternator then 140 Amps is acceptable ie it won't burn it out. Is my understanding correct?

I understand at idle the alternater output would be less but traveling during the day would be the plan so I wouldn't be idling the Sprinter Chasis which I've heard is not good for diesel engines.

That's good to know, thanks!

My Daly is bad. I've switched to REC BMS. I don't think Daly is a valid product

I'm having the same issue. What did you do to correct behavior? I see you referred to sleep time, what did you set it to and is your problem resolved?

Freep, what did you end up going with for a DC-DC charger?

Recently I test drove a Coachman Galleria. I was very intrigued with the Air Conditioning. With the upgrade of 600 Amp hours of Xantrex lithium batteries in lieu of a propane generator they claim you can run the 20,000 BTU, 12-volt, DC Air Conditioner for 10 hours. With this upgrade package...

Thank you!
