The electrical portion of the project causes the greatest cost variation.

Your final cost is dependent on the existing electrical system setup, the location of electrical enclosures, possible rerouting of electrical panels and circuits, connections, wiring, and electrical installation costs required to connect the battery backup and meet local building codes.

After hundreds of ESS Battery Projects, we’ve found that most projects fall into one of three types:

  1. Easy Electrical – 10%+/- of the projects
  2. Medium Electrical – 85%+/- of the projects
  3. Hard Electrical – 5%+/- of the projects

Here are examples of what might be encountered at this stage to help you estimate which project type you may have.

 

Energy Storage Solution – Easy Electrical Setup

Easy Electrical Install*

Estimated Extra Electrical Costs $1,000 – $3,500

In this example all storage and electrical connections are:

  • Readily available and within code and specs
  • Spatially near each other
  • In unobstructed areas
  • Free of other home and utility equipment
  • Not located in an attic or crawl space

They also:

  • May require replacing or upgrading the home’s Main Electrical Panel
  • Have adequate physical garage wall space for all ESS equipment
Energy Storage Solution – Easy Electrical Setup

Medium Electrical Install*

Estimated Extra Electrical Costs $3,500 – $5,500

In this example all storage and electrical connections are:

  • Readily available and within code and specs
  • Within 30-45 linear feet (covers going across the ceiling of a typical 2-car garage roof)
  • In unobstructed areas
  • Free of other home and utility equipment
  • Not located in an attic or crawl space

They also:

  • May require replacing or upgrading the home’s Main Electrical Panel
  • Have adequate physical garage wall space for all ESS equipment
Energy Storage Solution – Easy Electrical Setup

Hard Electrical Install*

Estimated Extra Electrical Costs $5,500+

In this example all storage and electrical connections are:

  • Electrical connections are spatially distanced with the main electrical panel located a long distance from the transfer switch, batteries and/or circuits protected by the batteries.
  • Requires extra conduit/routing paths, terminations and equipment (typically greater than 45 linear feet).
  • Routing conduit on the building exterior is possible and conduit path is generally free of obstructions
  • Homeowner prefers not seeing long conduit transversing the home or opts for an attic or crawl space installation.
  • In unobstructed areas
  • Free of other home and utility equipment
  • Not located in an attic or crawl space

They also:

  • Typically require replacing or upgrading the home’s Main Electrical Panel
  • Have adequate physical garage wall space for all ESS equipment

*Site Survey Required to determine which level of installation you will need.
