Designed for systems centered on direct solar DC operation.

Combine solar contribution with grid or generator backup.

Match capacity to climate, insulation, windows and operating hours.

Confirm voltage, solar array, batteries and autonomy before quotation.
Select the power architecture around the site, autonomy target and available backup source.
01For off-grid projects designed around a DC solar power architecture.
02Size storage around cooling load, climate and operating schedule.
03Use solar with grid or generator backup where supply is unstable.
Use the table for initial selection, then confirm the final system with Besuncool for the destination climate and operating schedule.
The current published specification table documents BS17GW and BS26GW. Confirm the exact model-to-capacity mapping, room load and solar-system limits for the quotation.
