The process

How a battery retrofit works

Battery size alone doesn't tell you what a system will power. Here's how we go from your backup goal to installed storage.

  1. 01 · Start here

    List what needs to keep running

    A fridge and a few outlets call for a very different setup than whole-home backup.

    • Must-haves

      Refrigerator, lights, internet, medical equipment, a few outlets.

    • Nice-to-haves

      Pool pump, A/C, a second fridge or the garage.

    • How long

      A few hours through a short outage, or longer.

    • Your bills

      Recent bills show how much power the home uses.

  2. 02 · The review

    We look at your existing solar

    • Inverter

      Your inverter decides how a battery can connect.

    • Service panel

      Panel size, open space and whether a critical-loads panel makes sense.

    • Space

      Where the battery and equipment can go, usually the garage or a side wall.

    • Utility rules

      APS, SRP and TEP each have their own interconnection requirements.

  3. 03 · The plan

    Equipment and a clear scope

    • Right-sized battery

      Matched to your loads, not the biggest box on the shelf.

    • Brand options

      We compare EG4, Bluetti and EcoFlow for your setup.

    • Electrical scope

      Panel changes, critical-loads panel or new inverter equipment, spelled out.

    • Pay over time if you need to

      Financing through Wisetack. Subject to credit approval.
