We have a Quattro 12 | 5000 |220-100|100 120V on our Dufour 530. We envision cruising to areas where the shore power will be 220 - 230v. Will the 3600 Watt Auto Isolation transformer have enough capacity to power our boat on 230v shore power?

Isolation Transformer Size for 230v shore power
Depends on your AC loads and shore power limit (power assist mode) you have set. You can limit the maximum consumption from shore power in your Quattro. e.g. 3000W Moste of the time you don’t need 3000W, and if you need e.g. 4000w the missing 1000w coming from the battery bank, if you need 4500w, 1500 w coming from the battery’s. And when the consumption is lower then the 3000w e.g. 2000W the battery charges back to 100%soc with 1000w.
Perfect! I've got a Cerbo GX and have just started logging the data. With enough history, I can identify our demands and patterns to determine just how often power assist kicks in and whether the transformer is large enough. Also, it will help size our new battery bank if or when we switch to LiFePO4 with more solar. Knowing the shore power profile nails down one variable and helps define the battery and solar options.
