Yes, but at the same time, the following equation must also be true:
Apparent Power = Current x Voltage
And if Voltage is 230V and Current is max 37A, then apparent power cannot be 10,000 VA.
In off-grid mode, the ratio between the max. active power to the max. apparent power is not a power factor.
In off-grid mode, the power factor is set by the load.
The Quattro can supply any load at any power factor as long as the apparent power is max 10 kVA AND the active power is max 8 kW.
The Quattro is responsible for the power factor in one of the following cases:
A. When charging the battery from the grid or generator AC input (the Quattro is a load on the grid or generator).
B. When exporting power from the battery into the grid with ESS.
Typically a PF=1 is used, but the DNO may require grid-tied inverters to run at a slightly lower inductive power factor to support the capacitive reactive loads from the grid that would otherwise lead to increased grid voltage.
