Solar + Storage Systems

Maximize your solar investment with integrated solar + storage systems from PES Supply. By pairing solar panels with battery storage, you can store excess daytime production for use at night, during outages, or during expensive peak-rate hours. Shop complete systems with panels, hybrid inverters, and LiFePO4 batteries from Sol-Ark, EG4, Fortress Power, Schneider Electric, OutBack Power, and more.

Solar + Storage Benefits

  • Energy independence – use your solar day and night
  • Outage protection – automatic backup when the grid fails
  • Self-consumption – stop selling solar cheap to the grid
  • Time-of-use savings – charge off-peak, discharge peak
  • Demand charge reduction for commercial customers
  • Scalable – start small, add batteries later

Modern LiFePO4 batteries offer 6,000+ cycles and 10+ year lifespans, making solar + storage more affordable than ever. Hybrid inverters manage everything automatically, routing solar to your home, battery, or the grid based on your settings. Our team helps you size storage for your daily usage and desired backup duration.
