I am still in the design phase for my remodel. have four questions for you, please:
1) Double-checking my design, I have two Quattro's together supplying 240VAC. The LG minisplit outdoor unit spec sheet says input voltage should be 208-230VAC.
I noticed on your VRM it says "120.0" and "120.2" volts. Adding that together should mean 240.2V is being supplied to the LG unit? That is over 230VAC. Is this an issue with the LG?
2) Do you have any 240VAC appliances that require 4-wire connections? That is, two hots, a neutral, and a ground?
3) Does your generator supply 120VAC or 240VAC? If only 120, does it supply both Quattro's?
4) If I have the correct schematic for your system, you are NOT using AC OUT-2 on either Quattro. Is that still correct?
I appreciate you sharing your knowledge. Thanks!!!
1) Not a problem at all. US split phase is 240+ volts
2) Nope; though by testing with a meter, all the appropriate voltages are available and would work for such a device
3) 120. One quattro connects to it and uses it to pass power through on that leg and/or charge the battery. The other Quattro remains inverting. Pure magic! 240 split phase inside no matter what you're connected to for shore power
4) Correct, I don't need an output that's only on when I'm connected to shore. I'm also not currently using AC IN-2 ... though that will change if I get a permanent on-board generator
Given my loads, I really never need more than 13.4 amps (minimum amp draw for the 5k quattro) at 120v. The only time I set it to draw more is if I'm trying to recharge the battery more quickly (e.g. to shut down the generator by sunset).
