Parallel MP2 3K with MP 2K to add capacity

If I install an MP2 3K (12/3000/120-50) now and later decide I want more output capacity (wife wants to run AC, Microwave, Induction Stove all at same time), can I add a MP 2K in parallel to MP2 3K with synced output to single 120V line? Or is parallel only available for equivalent sized units?

Thx.

Parallel units must be the same model, running the same firmware. It is also recommended they be purchased at the same time to avoid differences in manufacture (parts differences) that could affect proper load sharing.

You would also need to increase your battery bank in order to supply the increased load.
