Hi.
My current setup is below. I'm am fully off the grid. I have a large battery bank and 3000w of solar. I currently run House A off my multiplus with my generator as backup. I only run House B off my generator. It currently uses 240v for the AirCon, but, my AirCon just broke and I need to install a new one.
I have two things going on right now. 1) I want to expand my Victron system to power House B off my solar/battery setup AND 2) I need to replace my AirCon, so, could replace it with a 120v system. The 120v systems use more power, but, I wouldn't need to worry about 240v anymore.
Questions:
1) Would you go through the hassle of getting 240v setup with a Victron system, or take the efficiency loss and keep it simple with 120v? (240v AirCons are available in 33 SEER, 120v only go up to 18 SEER)
2) If I want to go with the 240v, I assume this is what I need to do. Please let me know if I'm correct.
- Get one more Multiplus 3000 and set them up to run in Split phase
- Power both Multiplus from receptacle #4 set to 240v. One hot wire would go to Multiplus #1 and the other hot wire would go to Multiplus #2. They would share the negative and ground wires.
- The max out of receptable #4 is 22.9a x 240v = 5500w (the generator max) so we're all good there
- The 240v AirCon unit would get power from both hot wires, 1 exiting Multiplus #1 and the other exiting Multiplus #2
- House A would get its 110v from Multiplus #1, House B would get its 110v from Multiplus #2 to try and keep it balanced.
3) Will the split-phase stay in sync with this setup? Or if they're unbalanced, will the phase get messed up? Do I need a Victron Autotransformer?
THANKS for you help!!!
