Extended Backup for Longer Outages
The Dory Sentry PLUS steps up to 3,800 watt-hours of stored energy, giving you substantially more time on battery when the grid goes down. Its 2,400 watts of continuous pure sine wave output, with 4,800 watts of peak and surge power, runs the appliances your household depends on, from the refrigerator to the furnace.
Instant, Uninterruptible Power
Rated as a 2200VA uninterruptible power supply, the Sentry PLUS takes over the moment utility power fails. Computers, networking gear and home healthcare devices stay on without a restart, making it a dependable choice for anyone working from home or relying on medical equipment.
Days of Power, by Dory's Estimates
Dory estimates a single Sentry PLUS can run a refrigerator for 4 days, a home furnace for 3 days, a desktop computer for 5 days, a CPAP machine for 12 days, and phones and lights for 16 days. Connected to an electrical panel, Dory states it can run the critical devices of a 2,000 sq ft home for two to three days.
Charge from the Wall or the Sun
A 120V wall outlet charges the Sentry PLUS to full in about 2.5 hours. A built-in MPPT solar input connects directly to solar panels for clean, fuel-free recharging at home or off the grid.
Durable, Quiet and Safe
A steel metal structure and enclosure, stainless steel foldable handles and casters give the Sentry PLUS a solid, movable build. Dory rates the Sentry series for more than 10 years of service. With no fuel, no emissions and no engine noise, it operates safely indoors as well as outdoors.
Built to Grow with You
Connect multiple Sentries together for longer runtimes, or connect units individually through your electrical panel so they power exactly the circuits you need.
