2.2 Product Features
▪ High Conversion Efficiency: Advanced 3-level conversion topology
with Space-Vector PWM; Max. efficiency: 97%, CEC efficiency: 96.5%.
▪ Grid Adaptability: Selectable grid standards: IEEE 1547-2018, ISO-NE,
CA Rule 21, and HECO; Reactive Power; >0.99 PF (±0.8 adjustable),
Selectable Apparent Power rating enables Full Active Power rating to
+/-0.91 PF, and optional local or remote Active Power Curtailment.
▪ Flexible Communication: Supports standard CPS Modbus RS485,
SunSpec Modbus, and HTTPS/XML communications via FlexOM
gateway card to ensure compatibility with 3rd party monitoring and
control systems. The FlexOM gateway card enables further
command/control as well as remote firmware upgrades. (FlexOM
gateway card is optional accessory. Refer to FlexOM gateway card
manual for further detailed information.)
▪ Wide DC input voltage range: Operating DC Input Voltage Range: 200-
950VDC; Max DC input voltage: 1000VDC.
▪ Long Service Life: Designed with thin-film and electrolytic capacitors to
extend inverter's service life.
▪ 3 MPPTs: Multi-channel MPPT (Maximum Power Point Tracker) enables
maximum design flexibility and energy harvest optimization over the life
of the system.
▪ Separable Wirebox: The SCA25KTL-DO/US-208 includes a rapid
shutdown wirebox with integrated PLC transmitter for use with APS RSD-
S-PLC/RSD-D products.
▪ High Protection Degree: Powder coated aluminum NEMA 4X enclosure
meets the demanding needs of both indoor and outdoor use.
▪ Intelligent Integration: Integrated DC/AC disconnect switches, and up
to 6 fused string inputs eliminate the need for external DC combiner
boxes, simplifying installation and the need for DC BOS equipment.
