What we review before a Bradbury Powerwall proposal.

Bradbury battery planning should start with the property, not a generic package. Estate homes can have multiple panels, long conduit runs, larger HVAC loads, gates, pumps, security systems, EV charging and backup priorities that change the correct Powerwall design.

1. 1Confirm SCE details: utility account, rate plan, Net Billing assumptions, PSPS history, interconnection steps and current battery program requirements.
2. 2Review electrical capacity: main panels, subpanels, meter location, transfer equipment, Gateway location and any backup load panel needs.
3. 3Choose protected loads: refrigerator, internet, lighting, security, gates, garage access, pumps, selected HVAC circuits and EV charging plans before sizing the battery.
4. 4Coordinate solar and roof timing: compare Bradbury solar installation, roof replacement and the Powerwall backup planning guide before finalizing scope.

The final proposal should separate Powerwall equipment, Gateway or backup panel scope, permit assumptions, SCE steps, SGIP assumptions, financing and excluded loads.

Fire zone, PSPS, and SCE: estate-level battery planning.

• →San Gabriel foothills fire zone. Bradbury is surrounded by the San Gabriel Mountains and situated in a Very High Fire Hazard Severity Zone. SCE implements PSPS shutoffs in Bradbury during extreme fire weather events. A Powerwall paired with solar provides automatic, fuel-free backup that recharges each sunny day — without the noise, exhaust, or fuel logistics of a generator.
• →Estate-scale home sizing. Bradbury properties are typically large, with multiple HVAC zones, pools, and significant electrical loads. We size the battery system through a complete load analysis of your specific property — whether you need whole-home backup (all circuits live during an outage) or essential-load backup (selected critical circuits protected). We do not treat backup duration as fixed.
• →SCE territory and NEM 3.0. Under Net Billing, self-consuming solar via Powerwall can be useful compared with relying primarily on exports, depending on rate plan and usage. We design every Bradbury system around both outage resilience and NEM 3.0 planning. We do not promise a specific financial outcome.
• →SGIP Equity Resiliency review. Bradbury’s VHFHSZ designation and PSPS history may qualify homeowners for the SGIP Equity Resiliency tier. Eligibility requires income qualification, PSPS event history, minimum battery size, and available program funding. Subject to review. We review during your estimate. We are not a tax advisor.
• →Enphase IQ Battery as an alternative. For properties with Enphase microinverter solar, Enphase IQ Battery 5P is a modular alternative that scales well for large estate loads. We install and review both systems during your estimate.

What to review before choosing a Powerwall design.

• 1Load priorities: decide whether the project should protect essential loads only or support broader estate-scale backup.
• 2Electrical readiness: collect main panel, subpanel, meter and equipment-location photos before final battery sizing.
• 3Solar and roof timing: review Bradbury solar planning and roof replacement timing before installing solar-backed storage.
• 4Program review: confirm SCE, SGIP, manufacturer, financing and tax assumptions under current rules before relying on incentive numbers.
