Ve.direct inverter (phoenix) 48/1200, how to parallel?

I have seen that its possible to run these in parallel to boost power. I have a couple sbv4600 units that the inverter is blown or bricked by zendure. Im using the victron connected to this all in one unit’s battery.

But how do you parallel 3 units?

Is it a special cable?

Or do you need a cerbo-gx and 3 cables?

Or is it just not possible?

I have 1 victron coming and if i cant parallel them its fine because i have some equipment in a shed and 1200 is enough power. But getting 2 other sbv4600 to be useful again would be nice too.

Only the multiplus models with ve.bus ports can can be paralleled together, not possible with the pheonix ve.direct inverter units. Also just be aware its basically good for 1000W anything beyond that and it’ll eventually shutdown.
