Off-Grid

Stand-alone battery based systems, back-up generators, and hybrid configurations are ideal for remote areas where utility service is unavailable or cost prohibitive to install

Standalone or backup systems are designed to store the energy they generate in large battery banks to be used at a later time, giving you the ability to be completely independent of grid power

Standalone or backup systems differ from grid-tied systems in that standalone systems are designed to store the energy they generate to be used at a later time. Typically the energy generated is stored in large battery banks giving standalone systems the ability to be completely independent of grid power.

Standalone systems are highly desirable in situations in which the utility grid is non-existent, unreliable, or too costly to connect due to distance. The following are some excellent applications for standalone solar systems:

  • Commercial, Agricultural, or Residential energy users that can not afford to be without power or have critical loads
  • Computer Universal Power Supply (UPS) and server backup systems
  • Remote telecommunications and signaling systems
  • Remote Cabins, Residences or Houseboats with no other convenient source of power
  • Recreational vehicles (RV’s)
  • Structures for which it is too expensive or too far to run utility power

Standalone systems have different design considerations than grid-tied systems. Standalone systems typically generate electricity at a lower DC voltage in order to provide a more appropriate match to battery voltages. As a result Standalone systems require special invertors and other additional equipment.  In the event of extended cloudy days or low solar resource a back-up generator is recommended to be incorporated in order to guarantee power.
