The 280WMONO-W is the wide-format, higher-voltage 280W variant. With a 32V working voltage and 39V open-circuit voltage it is designed for 48V battery architecture and for series stringing, where higher voltage reduces current and therefore cable losses over distance. Its broader 1640 x 992mm footprint suits ground-mount frames and larger roof planes.
Key features
- 32V Vmp / 39V Voc: Built for 48V battery systems and series strings with lower cable loss.
- Wide 1640 x 992mm format: Better suited to ground mounts and broad roof planes than narrow rails.
- 8.75A maximum current: Higher voltage, lower current — efficient over longer cable runs.
Typical applications
- 48V off-grid systems: A direct match for 48V battery banks and hybrid inverter inputs.
- Ground-mounted arrays: The wider frame suits frame-and-post mounting on open ground.
- Large rooftop installations: Strings efficiently into high-voltage commercial arrays.
