What Every Homeowner Should Know About Backup Power (Before the Next Storm Hits)

The next time strong winds or heavy storms knock out power, ask yourself—are you ready? For many Maryland homeowners, the answer comes after the lights go out. That’s why backup power systems—generators or battery backups—are becoming more than just a convenience. They’re peace of mind.

Let’s start with the basics. There are generally three types of backup power options for homes: portable generators, standby generators, and battery systems.

Portable generators are the most affordable and flexible. They run on gasoline or propane and can power essentials through extension cords or a manual transfer switch. The downside? They need to be operated outdoors, refueled regularly, and don’t turn on automatically when the power goes out. Still, for short outages or budget-conscious households, they offer a solid stopgap.

Standby generators, often powered by propane or natural gas, automatically kick on when power is lost. They’re reliable and well-suited for powering large appliances like refrigerators, sump pumps, and HVAC systems. But they also require professional installation, routine maintenance, and a fuel source.

Battery backup systems, on the other hand, are quieter, cleaner, and often paired with solar panels. They’re ideal for powering essential circuits like lighting, Wi-Fi, and medical devices—and they don’t rely on fuel. While they may not support every system in the home, newer battery technologies are closing that gap fast.

Here in Maryland, state regulations require that all generator installations be completed by licensed master electricians—you can’t pull a permit on your own. Every phase of the work, including gas line installation, must be handled by licensed professionals. This helps ensure safety and compliance with local building codes, especially since generator size must also be based on power demand and safe waste handling.

Now, when it comes to commercial properties, the systems scale up dramatically. Businesses often rely on industrial battery banks or multi-phase standby systems to maintain operations. These setups are engineered to keep security systems, servers, or production lines running without a hitch.

The good news? Reliable backup power isn’t just for big operations anymore. With more accessible technologies and clear state guidelines, homeowners now have powerful tools to protect their families, their food, and their peace of mind—no matter what the weather brings.
