The Victron dealer weighed in about the 230V to 110V question with:
Your Ok,
So the Quattro 2 is not split phase plus it's not available. Shipments are not even in Holland yet. The Autotransformer is what gives you the split phase, you need to disable the Ground bond on the multiplus and run a DC ground jumper to the autotransformer. Pretty easy and then you have a true 120/240 output to run to your cabin. On the input side (generator) you have 240 L1 and L2 and ground but because it's straight 240 you don't have a neutral requirement.
On your LRA issue its a soft start variable speed HP so that is key here and it looks like its peak is around 5k. Is it water to water or water to air? I would typically look at your well pump and other loads as this heat pump will be on alot to see how much head room you have on the inverter sizing. The KVA gives you a number you can calculate power factor from. Look for PF on your data sheets and that will tell you more about what the inverter can do. if there is a traditional well pump it's probably a .8 PF so if it was 1000w you would need 1250VA of inerter..
