Growatt SPF 5000 Wiring AC Out

[FunkyBunch]

Hello,

Some questions below regarding the Growatt SPF 5000 inverter. I am looking to set one up as follows:

House Main Distribution board 63A
Take a 50A supply from this MDB with one cable to the AC Input of Inverter.
Connect a Battery to Inverter.
Charge Battery by night and discharge by day.

1) Can the Inverter feed the power back through this cable without using the AC out terminals?
2) Is AC out for off grid use only?
3) If battery is discharging by day at a low level and a large load comes on, can the grid assist this?

Assuming Growatt SPF-5000-ES

1) Can the Inverter feed the power back through this cable without using the AC out terminals?

No
This is not a grid-tied inverter.

2) Is AC out for off grid use only?

No
It can also pass the grid through to the loads.

3) If battery is discharging by day at a low level and a large load comes on, can the grid assist this?

No
When in battery mode. The grid is disconnected.

Thank you. How many amps is the bypass rated at?

Might check the manual.
