The

Don’t feel helpless when the power goes out.
Prepare your home with a backup home power system.
Instant power when you need it – quiet, instant, no worry or fuss.

Traditional gas generators can take weeks to install
Gas generators require permits, gas line work, and inspections before a single watt flows to your home. A battery-backup generator connects to your panel and is up and running fast. Gorjanc handles everything, start to finish. We have your home's emergency generator in stock and ready for installation.

What’s the difference between a backup power system vs. a traditional gas generator?
The Dory Sentry isn’t just a generator – it’s a new category of emergency power home protection. Here’s how it performs compared to traditional gas generators and other battery alternatives on every measure.
Dory Battery Generator
Maximum protection during power outages. Panel-ready, expandable, built for Northeast Ohio summers and winters.
Traditional Generator
Natural gas-powered protection during power outages. Integrates with home electrical panel.
Other Battery Generators
Mass-market consumer models in plastic housings. Limited lifespan and charge retention.
13 years of battery research, built into every Sentry.
The Dory Sentry was invented by one of the world's leading lithium-ion battery experts to solve his own power outage problem. Put that reliability to work in your home.
Instant, automatic switchover
The moment the grid goes down, the Sentry takes over – with zero lag. No surge, no flicker, no restart. Your sump pump, CPAP, and refrigerator never notice. Neither does whoever is home.
AI-driven 3-layer safety
Real-time sensing measures voltage, current, load, and temperature simultaneously. No traditional gas generator or competing battery brand offers this level of built-in protection.
Solar + wall rechargeable
Recharge from the wall in about 2.5 hours, or with available solar panels options via the built-in MPPT charger.
The benefits: No fuel to buy, no storage risk, no carbon monoxide, ever.
Steel body, built for a decade
Other battery generators use plastic housings and burn out in 3–5 years. Dory's full metal body and UL-certified LiFePO4 cells are rated for 10+ years.
No oil changes. No annual tune-ups.
