Thanks for all the insights. I think we're going to stick with 12V if I can make it work. If I had the time I'd play with the 48v to 12v system, but it does seem like a lot of added complexity.
For the 12/3000/120 Multi Plus II in split phase, can you use an auto transformer to balance the...
Well, one circuit for my cooktop is. It is an induction 220V unit. I know because I had to replace it of course :)
One other reason for the 220v is I would like to install a 18k BTU mini-split which requires 220v, so rather than spend the money on an autotransformer for a 120V output, I figure...
I currently have
4 12V 300AH LiTime
1 Magnum 2800 Watt inverter w/ 120 Amp charger
1 Victron 100/50 MPPT Solar charge controller
4 Newpowa 220W Solar Panels in series (880W)
1 Victron 500A Smart Shunt
I cannot run ACs, Cooktop (220V), Dishwasher, Washer, or Dryer with the current inverter...
I guess I thought it would be ok with 1200AH and that being < 0.5C but that is a lot of current if I maxed it out. Signs are pointing to converting to 48v for sure. That's why I asked. I researched a ton but figured people have real world experience and I can benefit from that.
If I want 220...
Justin, thanks, would you suggest 2 x MP 2 12/3000/120 2X120's or 2 of the "regular" MP 2 12/3000/120's?
I'm leaning towards this and potentially even an autotransformer on the output so I can use more than 3000 watts on either leg if needed. In this configuration would it be using the...
