    Powering a Mint Split unit in an RV by solar and lithium batteries

    I setup my split phase so that I had a dedicated 240V Breaker for the mini split. And a 30A breaker(s) supplying each side of my ac distribution panel and balanced my loads in the panel. That gave me a total of 6000W power in the distribution panel (excluding mini split. Wife would run the...

    if the unit will use single phase it is possible. never tried too chicken.

    Powering a Mint Split unit in an RV by solar and lithium batteries

    this load calculator is not 100% but it might get you there... remember that inverters can be as low as 75% to 90% efficient...the more expensive the unit usually the better

    Powering a Mint Split unit in an RV by solar and lithium batteries

    BTW.... remember to keep receipts for eveything... bolts, panels, wire, framing, tools... you get some back when you file taxes.... Your rig has a bedroom, kitchen and bathroom...qualifies just like a house. I got 30% back on the first rig and I think 26% back on the current rig on fed...

    Powering a Mint Split unit in an RV by solar and lithium batteries

    sorry for the delay today was a travel day. There are so many variables to the question... how well insulated is the rig, air leakage, how hot is it outside, where the rig is located.... are the temps at night comfortable enough to open windows. I know that on both rigs I over built the...

    Powering a Mint Split unit in an RV by solar and lithium batteries

    That sounds like you will have a sweet setup when you are done. I had a cassette in the Dutch Star only because I did not have any wall space inside the RV. I like the wall unit we now have (more efficient to convert dc to 120V AC) because it keeps the install simpler (1 Inverter no sub...

    Powering a Mint Split unit in an RV by solar and lithium batteries

    key is an energy audit... with our expected usage.. it was projected to keeps us going for at least 3 days. turns out I over estimated our usage

    Powering a Mint Split unit in an RV by solar and lithium batteries

    We do try to chase 75-85 temps. We actually prefer open windows and fresh air... we do run the air during the day for the pets...nice to not have to worry about them when we are out running around in hot weather. We do not typically run the ac overnight. The closest we have come to that was...

    Powering a Mint Split unit in an RV by solar and lithium batteries

    sorry that was confusing... total of 16 cells in 2 packs of 8 cells (24V)

    Powering a Mint Split unit in an RV by solar and lithium batteries

    Hookem,, I used Lishen 272AH cells. 8 cells in 2 packs. so the battery bank is 544AH at 24V. It is larger than my old 48V because I wanted to have the reserve for several days of cloudy weather or being parked under trees.

    Powering a Mint Split unit in an RV by solar and lithium batteries

    forgot to mention that I also had a 21 cu ft residential fridge and cooking on induction cooktop on the old rig...if your setup is different you may not be as much of a power hog as we were. I did a quick laod worksheet to ballpark my needs on the new rig...still over built

    Powering a Mint Split unit in an RV by solar and lithium batteries

    That was for the whole rig. Reused existing cabling saved time and money. Inserted (with breaker) 48V to 12V converter to handle 12V loads. Just built out new rig with 24V system (544AH) with single 3k Multiplus and a wall mount mini split. kept propane for cooking and wave6 heater this time...
