Outages in Arizona come with a cost: food, comfort, medical equipment, work-from-home downtime. A properly sized battery system bridges outages automatically — most homeowners only notice the lights never flickered.
We install and service every major platform — Tesla Powerwall, FranklinWH, Enphase, and EG4 — and recommend based on your loads and budget, not a quota. Solar-paired or standalone.

The most common battery mistake is buying the wrong size — too small to matter or too big to pay off. We start from your panel schedule and real consumption, then model outage scenarios with you: what must stay on, for how long.
You get the numbers in writing before you decide. That is the GreenTag way — education first, pressure never.
