Our take on the EcoFlow Delta Pro + Smart Generator

The EcoFlow Delta Pro + Smart Generator bundles a 3.6 kWh LFP home battery with a dual-fuel smart generator that starts itself when the battery runs low. The generator runs on gasoline or LPG, puts out 3200 W continuous and up to 4000 W peak with X-Boost, and adds a CO sensor with automatic shutoff. The pair weighs 83 lbs and runs about 8 hours at quarter load on gas. At $4,399 at Lightharvest solar as of November 5, 2026, it sits at the top of its recent range; four stores list it new.

Best forWhole-home backup for outagesOff-grid cabins and remote sitesRV and van life with high loadsOwners who want unattended auto-start charging
Pros
  • Generator self-starts in four modes to recharge the Delta Pro without you there
  • Dual fuel: gasoline or LPG, so you can run on propane when gas is scarce
  • 4000 W peak with X-Boost handles well pumps, fridges and power tools
  • CO sensor and five safety alerts with automatic shutoff add real protection
  • App control and monitoring for both battery and generator
Cons
  • 83 lbs for the generator alone; moving the pair takes two people or a cart
  • 70 dB at full load is loud for a campsite or a quiet suburban night
  • Only two AC outlets on the generator; you lean on the Delta Pro's panel for distribution
  • Propane output is lower than the 3200 W gasoline figure
  • Premium price; the bundle costs more than a battery plus a separate inverter generator

What reviewers say

  • 4.9 / 5338 ratings

Owners rate the bundle 4.9 out of 5 across 338 ratings and mostly praise the auto-start handoff between generator and battery. Complaints center on weight and noise at full load.

What people mention
  • Auto-startPraisedOwners say the generator fires up on its own when the Delta Pro drops to the set level, so outages need no babysitting.
  • WeightCriticisedAt 83 lbs the generator is hard to lift and move alone, and owners suggest a cart or a fixed install.
  • NoiseCriticisedFull-load running measures around 70 dB, which owners call too loud for campgrounds or late-night use.
  • Dual fuelPraisedRunning on LPG when gasoline is unavailable is cited as the reason buyers chose this bundle.
  • SafetyPraisedThe CO sensor and automatic shutoff are mentioned as reassurance for indoor-adjacent or garage setups.
  • PriceMixedBuyers accept the cost for the integration but note it is higher than buying a battery and generator separately.

Questions and answers

How does the Smart Generator work with the Delta Pro?
It connects to the Delta Pro and starts automatically when the battery hits a low charge level you set. It recharges the battery and shuts off when the battery is full.
Can it run on propane?
Yes. It is dual fuel and runs on LPG or gasoline. Continuous output is 3200 W on gasoline; propane output is lower.
How long will it run on a tank?
About 8 hours at a quarter load on gas. Runtime drops as load rises, so a full-load run is much shorter.
Is it safe to use near a house?
It has a CO sensor and automatic shutoff, but it is still a fuel-burning generator. Run it outdoors, away from windows and doors.
What can the 4000 W peak run?
With X-Boost the pair can start well pumps, fridges and power tools that draw more than the continuous rating for a moment. Check the startup watts of your appliance.
When is it cheapest?
The best new price was $4,399 at Lightharvest solar as of November 5, 2026, at the top of its recent range. Bundles like this tend to dip during holiday sales and when a newer model is announced.
