For a Coronado home on SDG&E’s delivery network, keeping motorized window shades usable during an outage starts with two checks: what powers each motor, and what sends its commands. A home battery can support eligible wired shade equipment on backed-up circuits, but powering a Wi-Fi router alone does not power the shades.
This equipment guide uses manufacturer and utility information checked November 7, 2026. It is not an outage notice. For address-specific conditions, use SDG&E’s official outage map.
Identify the power source before choosing circuits
Lutron’s Serena shade FAQ explains that battery-powered and wired-powered shades are different models selected when ordering. Do not assume a wired shade contains backup batteries or can accept them later.
Its Serena and Triathlon specification lists battery-powered, wired and manual models, plus compatible controls. These distinctions matter more than the word “smart” on a proposal.
For each room, record the model, motor power source, power-supply location and usual control. Have the installer trace a wired shade’s supply to the proposed backup circuit. A battery-powered shade instead needs its own batteries maintained according to its manual; a household storage battery does not replenish disposable shade batteries.
Separate saved settings from usable controls
The Lutron FAQ says power-failure memory retains programming, including presets and travel limits. That means settings survive lost power; it does not promise movement while the motor has no power.
The same FAQ says Serena mobile-device control requires a Smart Bridge. Ask the shade installer which functions remain available through a paired local remote and which need the bridge, network equipment or an outside service. Confirm the actual installation rather than assuming app access and local operation are identical.
Use a commissioning checklist:
- Demonstrate the intended outage control method with the installer.
- Confirm whether every wired motor supply and required controller receives backup power.
- Identify how to maintain shade and remote batteries.
- Keep model-specific instructions accessible without the app; do not force a motorized shade by hand unless its manual permits it.
The same dependency check helps with Coronado security-camera backup planning: powering one component does not establish that the whole system works.
Fit shades into the household backup plan
SDG&E’s Coronado project page describes the island’s transmission reliability improvements. That utility work does not identify which circuits your home battery supports. Have the proposal name the shade supplies alongside your other priority loads.
General battery guidance explains that supported circuits, stored energy and household use govern backup service. Check inverter output and simultaneous loads as well as capacity. Ordinary grid-tied solar alone generally does not provide outage power; compatible backup equipment and available sunlight are needed for outage-time solar recharge. No shade inventory establishes a guaranteed runtime.
A qualifying no-upfront solar-plus-battery PPA can help eligible homeowners access a broader backup system while preserving cash. The CPUC solar guide explains provider ownership and ongoing electricity payments. Review the PPA rate, escalator, term, battery charges, maintenance and remaining utility costs; availability and property eligibility require an actual proposal. No upfront purchase does not mean free electricity or guaranteed savings.
