Multiplus II: Maximum power output

Following scenario:

- MultiPlus-II 48/3000

- AC-In connected to public power grid (1)

- connected to big battery (48V LiFePo4) (2)

- AC-Out connected to internal grid (3)

How much power is available on (3)? Is this

- the max power from (1) plus 2.400 Watt (see datasheet below), so something like 10.000 Watt.

- only the power the inverter can generate, so 2.400 Watt?

So 32 A x 230 V -> 7.360 Watt?


Is this what the "Transfer switch: 32A" in the datasheet means?

That is correct.

However if it is inverting (no grid) it can only do the 2400W continuously at 25°C. (So closer to 10-11A)

So if you do have bigger loads out them on AC2, as it switches off (unless programmed different) automatically on grid loss.

It is sized like that so you can run your full loads and charge battery at the same time.
