small wind electric system balance-of-system components

storage batteries

Storage batteries for use with a small solar or wind electric system.

The balance-of-system parts – those in addition to the wind turbine and the tower – you'll need for a small wind electric system depend on your application. For example, the parts required for a water pumping system will be much different from what you need for a residential application.


The balance-of-system parts required will also depend on the type of system:


  • Grid-connected
  • Stand-alone
  • Hybrid.

    Most manufacturers can provide you with a system package that includes all the parts you need for your particular application. For a residential grid-connected application, the balance-of-system parts may include the following:


  • A controller
  • Storage batteries
  • An inverter (power conditioning unit)
  • Wiring
  • Electrical disconnect switch
  • Grounding system
  • Foundation for the tower.
