Whole-Home Backup Power Solutions

Protect your entire home from power outages with a comprehensive whole-home backup system from PES Supply. We offer two approaches: standby generators for automatic, fuel-based backup, and solar + battery systems for clean, silent, and fuel-free resilience. Shop top brands including Generac, Kohler, Sol-Ark, EG4, Fortress Power, and more.

Backup Power Options

  • Standby generators – 18kW to 26kW for full home coverage, automatic start
  • Solar + battery – silent, fuel-free, charges itself daily
  • Hybrid systems – solar + battery + generator for ultimate resilience
  • Transfer switches – automatic (ATS) for seamless switchover
  • Load management – prioritize essential circuits

A whole-home standby generator (22kW+) can power everything including central AC, while a solar + battery system provides clean, quiet backup with no fuel costs. Many homeowners combine both—batteries for short outages and a generator for extended ones. Our team helps you assess your loads and design a system that keeps your family comfortable and safe.
