Buying Guide

How to Choose Emergency Backup Power

The right backup depends on three things: how long outages last in your area, what you need to keep running, and whether fuel availability is a concern during a disaster.

Battery Systems: Best for Short-to-Medium Outages

Battery backup systems switch to power in under 20 milliseconds. No fuel, no fumes, no noise. Runtime is limited by capacity. A 3,000Wh system running essential circuits at 300W runs about 8 to 10 hours. Add solar panels to recharge during an extended outage. Best for homes where outages rarely exceed 24 to 48 hours.

Dual-Fuel Generators: Best for Multi-Day Outages

Dual-fuel generators run on gasoline or propane. Propane stores indefinitely in a tank on your property, making it the preferred emergency fuel. A 100-gallon propane tank provides 60 to 80 hours of runtime on a 4,500W generator at half load. No gas station lines, no spoilage, no running out. Tri-fuel models add natural gas as a third option if your home has a gas line.

Whole-Home Standby: Best for Automatic Protection

Standby generators install permanently, connect to your gas line, and start automatically when the grid goes down. No action required. They run indefinitely as long as the gas supply holds. Best for households with medical needs, sump pumps in flood-prone areas, or anyone who cannot tolerate power interruptions.

Pairing Battery and Fuel

Many prepared households use both. A battery system covers the first 12 to 24 hours with instant, silent power. A dual-fuel generator handles days two and beyond. This combination eliminates both the noise problem of running a generator around the clock and the limited-runtime problem of relying on a battery alone.

Frequently Asked Questions

Have a question about emergency backup power? Our team has answers. Call or chat anytime.

Battery backup systems store electricity in lithium cells and switch to battery power instantly, often in under 20 milliseconds. They run silently with no fumes and no fuel to manage. Runtime is limited by capacity - plan for 4 to 48 hours depending on the system and your load. Generators burn gasoline, propane, or natural gas and run as long as fuel is available, making them better for multi-day outages. Many homeowners pair a battery system for instant coverage with a generator for extended outages.

Fuel flexibility is the core emergency prep advantage. During extended outages, gas stations often close or run out of fuel. Propane stores indefinitely in a tank on your property and is unaffected by supply disruptions. Tri-fuel generators add natural gas as a third option - if your home has a gas line, it never runs out. A dual or tri-fuel generator with a full propane tank is ready for any outage regardless of gas station conditions.

Essential circuits typically include a refrigerator, sump pump, lights, and outlets. That load runs 2,000 to 4,000 watts continuously. For battery systems, plan for 4 to 10kWh of capacity to cover 8 to 24 hours. For generators, a 4,500W unit covers essential circuits comfortably. If you want to run central AC, a well pump, or heavy appliances, size up to 9,000 watts or more for generators, or a large expandable battery system with 240V output.

A standby generator is permanently installed outside your home and connected to your electrical panel through an automatic transfer switch. When the utility power goes out, the transfer switch detects the loss and starts the generator within seconds. The generator runs on LP or natural gas from your home supply line, so it never runs out of fuel. When utility power is restored, the transfer switch disconnects the generator and reconnects the grid. No action required from you at any point.
