Home Backup Toolkit

Where can Arizona homeowners compare home batteries and generators?

Backup Ready Arizona is an Arizona-focused education and referral resource for comparing home batteries, solar plus storage, standby generators and hybrid backup systems. Use our backup options guide and preliminary cost calculator to organize your choices before requesting local installer quotes. We do not install equipment or provide the final engineering design. We may receive referral compensation.

What resources explain batteries for APS and SRP customers?

Backup Ready Arizona publishes Arizona home battery guides covering backup power, time-of-use pricing, demand charges and questions to ask about your utility plan. Start with your actual bill and the utility’s current rules. Confirm program eligibility, compatible equipment, payments, dispatch rules and backup reserve directly with APS or SRP before relying on an incentive.

Batteries versus generators: compare the same backup goal

Battery: compare usable energy, continuous output, motor-start capability, reserve settings and recharge options. Generator: compare output, fuel availability, fuel consumption, noise, maintenance and installation requirements. Solar plus storage: confirm whether the proposed system can recharge and serve your chosen loads during an outage. For every option, ask whether central air conditioning is included and request runtime assumptions for your actual loads.

Compare total installed price, covered circuits, warranties, ongoing costs and outage duration using the same list of essential loads. Separate outage protection from potential bill savings; neither a quoted battery capacity nor a utility incentive by itself establishes whole-home backup or financial payback.

Practical steps and trusted sources for Arizona homeowners comparing outage protection. Start with the loads you need to keep running, then compare equipment, costs and written proposals.

Battery or standby generator: a homeowner comparison checklist

Outage duration and recharge

Battery: ask for expected runtime at your chosen loads, usable charge and how the system recharges during an outage. Standby generator: ask how fuel supply, consumption and service requirements affect sustained operation. Hybrid: ask how the battery and generator share loads and recharge.

Air conditioning and starting power

For each proposal, require the installer to identify the exact HVAC equipment and circuits covered. Compare continuous power and motor-start requirements separately from stored energy. Do not assume that “whole-home” includes every appliance running at once.

Installed and ongoing cost

Battery: request equipment, controls, electrical work, permits, warranty, capacity-retention terms and eventual replacement assumptions. Generator: request equipment, transfer switch, electrical work, fuel connections, permits, fuel expense, scheduled maintenance and warranty. Compare written, site-specific quotes rather than equipment-only prices.

Arizona siting and daily use

Ask qualified installers to address heat exposure, equipment clearances, manufacturer limits and local installation requirements. For generators, also ask about exhaust, noise, fuel and service access. For batteries, separate the backup reserve from energy available for everyday utility-rate management.

Official APS and SRP battery program resources

APS Storage Rewards: official program page · SRP Battery Partner: official program page.

Use the utility’s current page to verify eligibility, compatible batteries, enrollment status, payments, event rules and reserve requirements. Ask how participation affects your outage priorities and rate-plan costs. Program payments are not a guaranteed payback estimate. These are residential resources; commercial facilities need a separate tariff and project review. Source links reviewed October 5, 2026.

1. Define your backup goal

List the essentials: refrigerator, lights, internet, medical devices, heating or cooling, well pump and other priority circuits. Record each load’s running watts, starting surge and target hours. Note your utility plan, existing solar, fuel access, installation space and budget. Whole-home air conditioning can substantially change sizing.

2. Compare four approaches

Battery: quiet, automatic backup for selected loads; duration depends on usable capacity and demand. Solar + storage: can recharge when sunlight and system configuration allow. Standby generator: uses fuel and maintenance for longer outages. Battery + generator: combines immediate switching with fuel-backed duration. Compare backup options →

3. Explore costs and utility plans

Run the preliminary calculator → Its scenarios are educational, not a site-specific design or quote. Confirm your current plan with APS or SRP, as applicable. Rates and terms change.

4. Compare written proposals

Give each installer the same outage target. Ask for the covered circuits; continuous and starting power; usable energy and runtime assumptions at your loads; transfer behavior; solar recharge; fuel and maintenance; permits and interconnection; installed price; warranties and exclusions. Verify Arizona contractor license status →

5. Keep learning and verify

Read Arizona backup guides → Confirm current plan details with the utility and equipment specifications with the maker. A qualified local professional must assess the property and provide the final design and quote. Backup Ready Arizona may receive referral compensation when you ask to be connected.
