Dory Sentry PRO
Description
The Dory Sentry PRO is a 5,000 Wh battery generator in a steel enclosure. It delivers 3,600 W continuously and 7,200 W surge at 120 V, and it doubles as an uninterruptible power supply: devices plugged into it keep running when the grid drops.
It recharges from a wall outlet in about 2.7 hours or from 1,600 W of solar in about 3 hours, with no fuel and no noise.
Shipping and Delivery
Delivery: Free standard shipping within the 48 contiguous states. We do not ship to Alaska or Hawaii.
Dispatch: It ships from Dory Power in Ohio, usually within 2 business days, and arrives in about 3 to 7 business days.
At delivery: At about 128 lb, plan for two people to move it. Check the box and the unit before you sign, and contact us within 48 hours with photos if anything arrives damaged.
Key Features
5,000 Wh capacity: Several days of essentials in an outage.
3,600 W continuous, 7,200 W surge: Pure sine wave output at 120 V.
2,200 VA UPS: Instant, uninterrupted backup for computers, routers and medical devices.
Fast wall charging: About 2.7 hours to full from a 120 V outlet.
Solar ready: Up to 1,600 W of solar, about 3 hours to full. Solar panels connect directly to the built-in MPPT solar charger.
App and protection: A smartphone app with live support, and an integrated surge and drop protector.
Steel build: A steel structure and enclosure with stainless steel folding handles.
No fuel, no exhaust: It runs silently on battery power, so it can sit indoors next to what it powers.
Two finishes: White or Titanium.

What's Included
In the box: The Sentry battery generator. Ask us for the full packing list before you order if a specific cable or accessory matters to you.
Installation and Compatibility
Plug in what you need: Devices and appliances plug straight into the Sentry's own outlets. There is nothing to install.
120 V only: The PRO runs 120 V devices. For 240 V appliances, the Sentry PRO Max has 240 V output.
Home circuits: Running household circuits from a Sentry needs a transfer switch or interlock fitted by a licensed electrician, and most areas need a permit. None of that hardware is included.
Solar panels: Not included. Match the panels to the Sentry's solar input rating.
Where it goes: Indoors near the devices it backs up, on a floor that takes its weight.
Warranty
Term: 3 years, covering parts and labor.
Not covered: Shipping and handling costs for a warranty repair or replacement.
Claims: Keep your order confirmation. Contact us first with your order number and a description of the fault, and we take the claim to Dory Power's customer service.
Returns: Within 30 days of delivery, unused and in the original packaging, under our return and refund policy.
Frequently Asked Questions
What does the UPS function do?
Plug devices into the Sentry while it is connected to the wall. When grid power drops, the Sentry keeps them running without a break, which suits computers, routers and medical devices.
About how long will it run my appliances?
On a full charge, roughly 6 days for a refrigerator, 5 days for a furnace, 16 days for a CPAP machine, or 22 days of cooking three meals a day in a microwave. Real runtime depends on each appliance's draw and how many share the battery.
Can it run my home's circuits?
Not through its own outlets. Connecting it to your home's circuits needs a transfer switch or interlock and a licensed electrician. Plan the circuits you need with your electrician first.
PRO or PRO Max?
The PRO Max adds 240 V input and output, 8,300 Wh and 6,000 W continuous. If everything you need to back up runs on 120 V, the PRO is the lighter choice.

Who it is for
More capacity for longer outages
The Sentry PRO keeps the Sentry PLUS footprint and raises both numbers that matter in a long outage: 5,000Wh of lithium iron phosphate storage and 3,600W of continuous output, with 7,200W of surge for motors that start hard. Its 2,200VA uninterruptible power supply function moves plugged-in equipment to battery when the grid drops. It is 120V in and out; for 240V, look at the Sentry PRO Max.

How the Sentry works
Battery backup that switches on its own, charged from the wall or the sun
-
Takes over when the grid drops
Leave equipment plugged into the Sentry and it keeps running when utility power fails: every Sentry has an uninterruptible power supply function, rated 2,200VA on this model. The front display shows charge level and power in and out.

Runtimes on this page are estimates. Actual runtime depends on the load and how often it cycles.
Plain answers
Choosing a model, solar, backup switching and delivery
Which Sentry do I need?
The PRO suits a 120V backup plan that needs to run longer or start bigger loads than the PLUS. On a full charge it can run a refrigerator for about 6 days or a home furnace for about 5 days. Choose the PLUS if 3,800Wh and 2,400W cover your list, or the PRO Max if you need 240V or 8,300Wh.
Can I charge it from solar?
Yes. Solar charging goes up to 1,600W, which fills the battery in about 3 hours, through the built-in MPPT charger. Send us your panel details before you buy panels and we will confirm the match.
Is it a UPS?
Yes. Every Sentry has an uninterruptible power supply function, rated 2,200VA on this model: equipment plugged into it moves to battery automatically when utility power fails. The transfer time in milliseconds is not stated, so if you are protecting servers or medical equipment, ask us before you order.
What does it weigh, and how is it delivered?
The Sentry PRO measures 21 × 10 × 22 in and weighs 58 kg (about 128 lb). It rolls on casters and has stainless steel handles; lifting it is a two-person job. Shipping is free within the 48 contiguous states. Dory ships it from stock, typically within 2 business days, and delivery usually takes 3 to 7 business days after that.
How long will it run my appliances?
On a full charge, the Sentry PRO runs a refrigerator for about 6 days, a home furnace for about 5 days, a desktop computer for about 7 days or a CPAP machine for about 16 days. Real runtime depends on the appliance and how often it cycles, so treat these as a starting point.
