Vulture City Off-Grid Ranch

Overview

A historic Arizona ranch operates entirely off-grid with a Sol-Ark hybrid system, supporting daily ranch operations and visitor facilities.

The challenge

Located miles from the nearest utility line, the property required a robust off-grid system capable of handling variable seasonal loads while remaining low-maintenance for remote operation.

The solution

Sol-Ark hybrid inverters with a stackable battery bank provide reliable autonomy, with PV oversizing to ensure consistent state-of-charge through cloudy stretches and shoulder seasons.

Results

• Eliminated diesel-generator dependency for primary loads
• 24/7 monitoring enables remote troubleshooting
• Predictable energy costs with no utility bill
