SunWize® Power Ready Systems

SunWize Power Ready Systems are complete, fully integrated power supplies designed for site loads requiring 48 volts DC. Each system provides safe and reliable power generation without the need and expense of installing utility power. The sealed, maintenance free batteries are designed for deep cycle operation and extended life in solar applications. The aluminum array support structures and battery enclosures are strong yet lightweight and corrosion resistant for harsh marine or severe weather locations.

For continuous loads of 1 to 100 watts, Power Ready Systems are ideally suited for remote locations. The 750 watt system shown above is a telemetry system used for water quality monitoring.

Features and benefits

  • Solar modules are fully encapsulated to resist harsh weather conditions
  • Low voltage load disconnect
  • Sealed, lead-acid battery designed for deep discharge cycling
  • NEC code compliant overcurrent protection and safety disconnect
  • Temperature compensated battery charging
  • Corrosion resistant control/battery enclosure
  • Installation, operation & maintenance documentation
  • Preassembled, prewired systems minimize field installation time and eliminate wiring errors
  • Solid state electronics for improved efficiency and reliability
  • Low maintenance and operating costs
  • Complete systems reduce specifying and buying time
  • Quality components assure long system life
  • Full system warranty available on prepackaged systems
Shipping and Handling - Power Ready Systems are designed to withstand rugged transportation to remote sites. On chest-style enclosures, optional single-lift lugs and helicopter handling features are also available. Each subsystem is fully assembled for factory testing before shipment. The prewired systems are typically shipped with a protective cover over the array and are secured to a skid. The solar array for larger systems is shipped in a separate plywood crate (optional) and the battery enclosure is mounted on a skid. In some cases, batteries are shipped separately.

Warranty - Power Ready Systems carry a one-year system warranty for materials and workmanship. The solar modules have up to a 25-year warranty. Careful component selection results in a system with a lifetime exceeding 25 years with battery replacements every five to ten years.
