Why a Battery Matters in the Bay Area?
• Outages and PSPS: PG&E outages and fire-season Public Safety Power Shutoffs can cut your power for hours or days. A battery keeps essentials like your fridge, lights, Wi-Fi and medical devices running.
• NEM 3.0: Under the Net Billing Tariff, extra solar sent to the grid earns low credit. A battery stores it so you can use it in the evening, when time-of-use rates are highest.
• Rising rates: Using your own stored power means you buy less from PG&E as rates climb.
Can You Install a Battery Backup Without Solar Panels?
Yes!
You can install a home battery backup system without solar panels.
When installed as a standalone setup, the battery charges directly from the grid during normal operation. When an outage occurs, an automatic transfer switch kicks in instantly to power your home's essential circuits.
- Silent & Maintenance-Free: Instant, automatic backup power with zero noise, fuel storage, or exhaust emissions compared to traditional gas generators.
- Grid Charging: Charges during standard grid operation and can take advantage of off-peak electricity rates if configured for Time-of-Use savings.
- Future-Proof: Fully modular and scalable, allowing you to integrate solar panels later whenever you're ready.
Generator and Battery Hybrid Backup Systems
Many homeowners assume they must choose between a generator and a battery backup, but combining them provides the most reliable protection.
In a hybrid setup, the battery delivers immediate, silent power the moment the grid fails, while solar panels recharge it during the day. If an extended outage depletes your stored reserves, the generator automatically kicks in to handle heavy loads and recharge the battery.
This layered approach minimizes generator runtime—saving fuel, reducing wear and maintenance, and ensuring your home stays powered without interruption.
