The 280WMONO-L is the low-voltage variant of the 280W panel. Its 20.52V working voltage and 22.4V open-circuit voltage sit close to a conventional 24V battery system, which makes it a natural match for retrofits and for sites already running 24V equipment. At 1722 x 765mm it delivers 13.65A, so comparatively few panels are needed to build a useful array.
Key features
- Low-voltage architecture: 20.52V Vmp / 22.4V Voc suits 24V battery banks and retrofit systems.
- 13.65A maximum current: High current per panel means fewer units for the same array output.
- 1722 x 765mm frame: Compact for its output, useful where roof area is constrained.
Typical applications
- 24V system retrofits: Drops into installations already built around 24V equipment.
- Residential rooftops: Builds array output quickly with a small number of panels.
- Off-grid installations: Charges large battery banks for cabins and remote sites.
