How to connect a Phoenix Inverter Smart 48/3000 in parallel?

Hi,

I want to add a Phoenix Inverter smart 48/3000 to the already existing one same model. Is it possible to place these inverters in parallel? Can any on show a diagram for placing them in parallel?

Are there challenges with firmware?

Do I need more safety fuses?

Thanks,

As far as I know the newer Smart Phoenix can't be paralleled. They only have VE.direct and not VE.bus.

From the datasheet:

Thanks Mattias, that is a bummer as we need more power in the house. Any suggestions? A seprate system with second battery bank. I do have two solar panels setups and two battery chargers. Is it ok then to feed the house from two inveters (same model but still two.)? Thanks.

As long as they are not connected on the AC output this it should work.

I think I would connect them to the same battery.
