Nature's Generator vs. EcoFlow vs. Jackery: Which Whole-Home Power System Is Right for You?

When the power goes out for a few hours, almost any power station will do. When it goes out for two or three days in January, the question changes: can this thing keep the furnace blower, the well pump, the fridge, and the lights running, and can it do that without you dragging extension cords through the house?

That's the job whole-home power systems are built for. Nature's Generator, EcoFlow, and Jackery all make systems designed for it, and on a spec sheet they can look similar: big inverters, LiFePO4 batteries, expandable capacity. In practice, they're built around three very different ideas of how backup power should fit into your home.

This guide compares the Nature's Generator MyGrid 10K and Lithium 6000, the EcoFlow DELTA Pro Ultra, and the Jackery HomePower 3600 Plus on what actually decides the purchase: how each one connects to your house, where it can live, what it can power, and how you'll recharge it when the outage drags on.

The Real Question: How Will the System Live in Your Home?

Before comparing watts and kilowatt-hours, decide which of these three setups matches your house and your habits. It narrows the field faster than any spec.

Setup Style	What It Looks Like	Best Match
Installed hub	A large inverter and battery that stay in one spot, anchored in a utility room or basement, connected to your panel through a transfer switch.	Nature's Generator MyGrid 10K
Smart-panel ecosystem	Stackable inverter and battery modules working with a dedicated smart home panel and app for automatic switchover and circuit control.	EcoFlow DELTA Pro Ultra
Roll-where-you-need-it	A wheeled unit that can power essentials through a manual transfer switch, then roll to the garage, RV, or job site.	Jackery HomePower 3600 Plus, Nature's Generator Lithium 6000

Side-by-Side: The Specs That Matter

All figures below come from the product listings at PowerGen Store. Always confirm your exact configuration before you buy.

Nature's Generator: The Installed Power Hub

Nature's Generator builds its whole-home systems to behave more like permanent equipment than portable gadgets. If you picture a backup system that lives quietly in a utility room and takes over when the grid drops, this is the brand built around that idea.

MyGrid 10K: The Heavy Lifter

The MyGrid 10K pairs a 10,000W pure sine wave inverter with a 10,496Wh LiFePO4 battery. That's the highest single-unit output in this comparison, and it supports 120/240V split-phase power, the kind your dryer, well pump, and central air need.

• Solar-ready at scale: up to 12,000W of solar input through dual MPPT controllers, enough to pair with a full rooftop or ground-mount array.
• Room to grow: expandable to 73.4kWh with additional MyGrid batteries, and two MyGrid units can combine for up to 20,000W continuous.
• Seamless handoff: a built-in UPS switches over in under 20 milliseconds.
• Built to stay put: it ships with a mounting bar, security brackets, and anchor chains, and it works with automatic transfer switches for connection to your home circuits.

The trade-off: the listing gives an optimal operating range of 68–86°F. Plan to install it in a conditioned basement or utility room rather than an unheated Northeast garage. The inverter (152 lb) and battery (213 lb) are also not something you'll move around.

Lithium 6000: The Mid-Size Option

Not every home needs 10,000 watts. The Lithium 6000 delivers 6,000W continuous (12,000W peak) with 120V/240V output from a 3,840Wh LiFePO4 battery. You can add 3,840Wh Power Pod batteries as your needs grow. Its auto-start mode stays idle while grid power is available and turns on when an outage hits. It integrates with transfer switches and power inlet boxes, and it recharges from solar, wind, or 120V/240V AC.

At 112 lb, it's a middle ground: movable when you need it, but happiest parked in one spot and wired to a transfer switch.

Pair it with: a Nature's Generator automatic transfer switch. They come in 30A, 50A, and 125A versions, so you can match the switch to the circuits you want to back up.

Best for: homeowners who want 240V backup for heavy loads, plan to add serious solar, and would rather install the system once and not think about it again.

EcoFlow DELTA Pro Ultra: The Smart-Panel Ecosystem

The EcoFlow DELTA Pro Ultra is built as a modular system: an inverter plus stackable 6kWh batteries, designed to work with the EcoFlow Smart Home Panel 2 for automatic switchover and circuit-level control from the EcoFlow app.

• Scales in both directions: 7.2kW of output per inverter, up to 21.6kW with three inverters and the Smart Home Panel 2. Capacity runs from 6kWh up to 90kWh.
• The most ways to recharge: solar (5.6kW per inverter, up to 16.8kW), the grid, a gas generator, or an EV charging station, with charging speeds up to 8,800W according to EcoFlow.
• No flicker: the online UPS lists a 0ms switching time, which protects sensitive electronics.
• Garage-friendly: rated IP54 and listed for operation from -4°F to 113°F.

EcoFlow says a single DELTA Pro Ultra can run a 3-ton central air conditioner. Actual results depend on your unit's startup draw, so check your AC's specs before counting on it.

The trade-off: you get the most out of it inside EcoFlow's ecosystem. The Smart Home Panel 2 is what unlocks automatic whole-home switchover and the higher output tiers, and like any panel connection it should be installed by a licensed electrician.

Best for: homeowners who want a polished, app-controlled system, need to install it in a garage, or want gas generator or EV charging as a backup for their backup. Browse the full EcoFlow lineup.

Jackery HomePower 3600 Plus: Serious Backup That Still Rolls

The Jackery HomePower 3600 Plus takes a different approach. Instead of an installed system, it's a 3,584Wh LiFePO4 power station on wheels, at 77 lb, that can still power home circuits when you need it to.

• Home-circuit ready: connect it through a manual transfer switch to power essentials like the refrigerator, lights, and water pump. The listing notes 120V/240V support when units run in parallel.
• Expandable: add battery packs to reach up to 21kWh.
• Long-lived: rated for 6,000 cycles to 70%+ capacity, with Jackery's 5-year warranty.
• Portable when you want it: it rolls from the kitchen to the garage to the RV, and it's rated to charge and discharge from -4°F to 113°F.

The trade-off: at 3,600W continuous, it's built for essentials rather than running your whole house at once. Switching to backup is manual through the transfer switch, and the listing shows up to 1,000W of DC (solar) input, which is much less than the installed systems above.

Best for: homeowners who want dependable essentials backup without a major installation, or who want one unit that also travels. See all Jackery systems.

Five Questions That Decide It

1. Do you need to run 240V appliances? A well pump, electric dryer, or central AC calls for 240V. The MyGrid 10K and Lithium 6000 offer it natively, the DELTA Pro Ultra offers 120V and 240V output, and the Jackery reaches 240V in a parallel setup. If you're on a well, our sump pump sizing guide shows how to size a power station for pump loads.
2. Where will it physically sit? An unheated garage in a Northeast winter points toward the EcoFlow or Jackery, which are rated down to -4°F. A conditioned basement or utility room opens the door to the MyGrid 10K.
3. How will it connect to your house? A smart panel (EcoFlow), an automatic transfer switch (Nature's Generator), or a manual transfer switch (Jackery). All panel connections should be installed by a licensed electrician.
4. How will you recharge during a long outage? If you plan a large solar array, the MyGrid 10K's 12,000W input stands out. If you want a gas generator or EV charger as a fallback, the DELTA Pro Ultra supports both.
5. How much will you grow? The DELTA Pro Ultra tops out at 90kWh, the MyGrid 10K at 73.4kWh, and the HomePower 3600 Plus at 21kWh. Our whole-home sizing guide shows how to calculate the capacity you actually need.

Before You Buy: Plan the Connection

The system you pick is only half the decision. The other half is how it connects to your home, and that's the part people most often leave to the last minute.

• List your must-run loads. Furnace blower, fridge, well or sump pump, lights, internet. Our power station size calculator helps you total them.
• Choose automatic or manual switchover. Automatic (smart panel or automatic transfer switch) takes over without you lifting a finger. Manual is simpler and costs less but needs you home.
• Book a licensed electrician. Any connection to your electrical panel should be installed by a pro to prevent dangerous backfeeding.
• Keep it healthy. LiFePO4 batteries last longest with a little care. See our LiFePO4 maintenance guide.
