اہم خصوصیات

MPPT Solar Charging

One MPPT tracker supports up to 6kW PV input on SF 4000 and 7.5kW on SF 6000, with up to 120A solar charging.

60–450Vdc MPPT · 500Vdc max. PV open-circuit voltage

Flexible Battery Support

SF 4000 uses a 24V battery system; SF 6000 uses a 48V system. Both support lithium, lead-acid and GEL batteries.

PV and AC dual activation · BMS port

Dual AC Outputs

Main and second AC outputs support smart load management. Quick-connect MC4 PV terminals simplify solar wiring.

Main output + second output · MC4 PV terminals

Flexible Operating Modes

Use utility or generator AC input alongside solar charging. Generator input requires an external ATS.
