Build planning with Quattro 5k + AT or 10k + AT?

I am planning for my off-grid build.

I want to use Victron Quattro Inverters.

I think that eventually, my total load will be from 12000 - 15000 watts peak.

But, in the build period, the A/C (unk. quantity at this time) units won't be in use, so we can utilize a smaller system during that time.

During the build, we will be running a refrigerator; small, (9 - 12k BTU) mini split; RV (2500 watt); electric dryer (240v); and a 120v water pump (1200 watts).


I'm thinking that since I need 240 split phase from the start, I would get two Quattro 5000 inverters.

When the house A/C comes online, then I could add a third Quattro 5000 to cover the total wattage.

I'm thinking the Quattro 5000 inverters would give me a certain level of redundancy.


But.... I don't know how to load balance.


I would like some help on how to divide the load between these inverters.

I don't know if the 3 - 5000's would allow me to handle large A/C loads while the dryer is running, etc.

Or would it be better to plan for 2 Quattro 10000 inverters with an Autotransformer in the beginning?


Any help would be appreciated.


Thanks.

Tom

Bigger is always better and more efficient. If budget allows, get as few larger systems as possible

Easier all round.
