What we review before a Carthay Powerwall proposal.

Carthay Powerwall planning should account for utility rules, panel capacity, HPOZ visibility, roof timing and the exact backup loads the homeowner wants protected. A written proposal should make the equipment location, electrical scope and excluded loads clear before installation.

1. 1Confirm utility details: utility account, rate plan, solar planning assumptions, interconnection steps and current program requirements.
2. 2Review older electrical capacity: main panel rating, breaker space, grounding, subpanels, meter access and backup load panel needs.
3. 3Plan discreet equipment placement: review garage, utility room or non-street-facing locations for Powerwall, Gateway and conduit routing.
4. 4Coordinate solar and roof timing: compare Carthay 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, HPOZ visibility considerations, permits, LADWP steps, incentives, financing and excluded loads.

Carthay: older homes and utility-aware battery planning.

• →Utility account review. Verify the actual utility account before planning solar or battery storage. Current utility rules, export rules, interconnection steps and program requirements should be reviewed before the battery design is finalized.
• →Older electrical systems: plan ahead. Panel capacity, existing loads, equipment location, HPOZ visibility considerations and any required electrical work should be reviewed during the estimate process.
• →HPOZ awareness for Carthay Circle. Homes within the Carthay Circle HPOZ may have design review considerations for exterior equipment. Battery equipment location should be reviewed by clearance, access, homeowner goals and any applicable design-review requirements before finalizing the written scope.
• →Backup configuration. Selected-load backup can prioritize critical circuits. Broader backup coverage depends on panel capacity, load profile, battery count, solar production and approved electrical design. Backup duration is subject to project-specific review.
• →Roof before solar + battery. For homes adding solar, roof condition matters. See our Carthay roofing guide.
• →Program and incentive review. Incentive pathways should be verified under current program rules before relying on any rebate amount or availability. Eligibility depends on funding, documentation, utility territory and project scope. Home Upgrade Specialist is not a tax advisor.
• →Enphase IQ Battery as an alternative. For Enphase microinverter solar homes, Enphase IQ Battery 5P is another option to compare. We review compatibility, backup goals, monitoring and budget.
