54
FacGenMax 60 - 66
Hz
65 The FacGenMax parameter selects the maximum
frequency the inverter will accept from the genera-
tor. If the generator frequency is greater than this
limit when running unloaded the Sunny Island
4248U will not connect, or, if the generator fre-
quency goes above this limit while connected the
Sunny Island 4248U will disconnect the generator.
FacGenMin 54 - 60
Hz
55 The FacGenMin parameter selects the minimum fre-
quency the inverter will accept from the generator.
If the generator frequency is lower than this limit
when running unloaded the Sunny Island 4248U
will not connect, or, if the generator frequency goes
below this limit while connected the Sunny Island
4248U will disconnect the generator.

GridNone:
No grid operation - Generator limits;
apply (VacGenMin, VacGenMax, FacGenMin,
FacGenMax, DelayVGenLow, PGenRevers).
GridCharge:
Charge only from grid - UL limits;
apply (voltage range 106 V - 131 V, frequency
range 59.32 Hz - 60.48 Hz), no reverse power
accepted.
GridFeedPV:
Charge from grid and feed grid with
Sunny Boy via Sunny Island; (voltage range 106 V -
131 V, frequency range 59.32 Hz - 60.48 Hz),
reverse power limit is 6.72 kW.

3000 The DelayVGenLow parameter selects the amount
of time the Sunny Island 4248U will wait before dis-
connecting when the generator voltage or fre-
quency drops below the VacGenMin or FacGenMin
limits.
Transition Ramp/
Fast
Fast The Transition parameter selects the way in which
the Sunny Island 4248U will transition from charge
to invert mode when it detects a grid or generator
fault.
