At 2 kWh, Bluetti’s Elite 200 V2 accepts 1,000 W of solar, twice the 500 W of EcoFlow’s DELTA 3 Max, for about the same $0.43 per Wh. At 1 kWh the two brands are closer: both take 1,000 W of solar and put out 1,800 W. EcoFlow units are lighter, while Bluetti often costs less during sales.

Quick answer

1 kWh tier: Bluetti Elite 100 V2 vs EcoFlow DELTA 3 Plus, both 1,024 Wh and 1,800 W.
2 kWh tier: Bluetti Elite 200 V2 (2,074 Wh) vs EcoFlow DELTA 3 Max (2,048 Wh).
Choose Bluetti for: more solar input at 2 kWh and strong sale pricing.
Choose EcoFlow for: lighter units, faster full wall charging at 1 kWh and a stricter published cycle rating.
Prices: about $380–$800 for 1 kWh and $879–$899 for 2 kWh at major retailers in October 2026. Sales move these often.

Bluetti Elite 100 V2 vs EcoFlow DELTA 3 Plus: which 1 kWh station is better?

On paper, these two are close to twins. Same capacity, same rated output, same solar ceiling.

The gap is mostly price. At sale prices, the math favors Bluetti:

Bluetti: $450 ÷ 1,024 Wh = about $0.44 per Wh (mid-range sale price)
EcoFlow: $719 ÷ 1,024 Wh = about $0.70 per Wh

Bluetti’s sale prices swing widely, so compare the price on the day you buy. EcoFlow’s edge is a published cycle rating with a clear end point (80% capacity). It is also expandable with add-on batteries. Bluetti’s page lists “4,000+ cycles” without saying to what capacity.

Bluetti Elite 200 V2 vs EcoFlow DELTA 3 Max: which 2 kWh station is better?

This is where the brands differ most. Bluetti doubles the solar input. EcoFlow saves you about 8 lb.

Spec	Bluetti Elite 200 V2	EcoFlow DELTA 3 Max
Capacity	2,073.6 Wh	2,048 Wh
AC output	2,600 W rated (3,900 W “Power Lifting” for resistive loads)	2,400 W rated / 4,800 W surge (3,400 W X-Boost)
Chemistry	LiFePO4	LiFePO4
Rated cycles	Not listed on product page	Not listed; EcoFlow cites about a 10-year lifespan
AC charge time	80% in 1.1 h; full in 1.4 h (1,800 W input)	0–80% in 68 min (1,800 W input)
Max solar input	1,000 W (12–60 V, 20 A)	500 W
Weight	53.4 lb	About 45 lb
Warranty	5 years	3 years + 2 years with app registration
Price, Oct 2026	About $899	About $879 on sale (list $1,499)

Price per Wh is a tie: $899 ÷ 2,074 = about $0.43, and $879 ÷ 2,048 = about $0.43. So the deciding factors are output, solar and weight. Bluetti gives you 200 W more rated output and double the solar input. EcoFlow is the one you can still carry to the car without a cart.

If you like EcoFlow but want more solar input, the DELTA 3 Max Plus (2,048 Wh, 3,000 W) lists 1,000 W of solar input and expands to 10 kWh. It costs more.

Which recharges faster from solar, Bluetti or EcoFlow?

At 1 kWh, it is a tie because both accept 1,000 W. At 2 kWh, Bluetti wins clearly. Here is the best case with enough panels, using 0.75 for real-world losses:

Bluetti Elite 200 V2: 1,000 W × 0.75 = 750 W. Then 2,074 Wh ÷ 750 W = about 2.8 hours of full sun.
EcoFlow DELTA 3 Max: 500 W × 0.75 = 375 W. Then 2,048 Wh ÷ 375 W = about 5.5 hours of full sun.

Most of the US gets 4–6 peak sun hours. So the Bluetti can refill from empty on an average day, while the EcoFlow needs a very sunny one. You also need the panels to match: 1,000 W is about five 200 W portable panels. Our portable solar panels guide covers sizing and connectors.

What about Bluetti Apex 300 vs EcoFlow DELTA Pro 3?

These are each brand’s 120/240V home-backup units. They differ in capacity, so compare them on price per Wh rather than head to head.

Spec	Bluetti Apex 300	EcoFlow DELTA Pro 3
Capacity	2,764.8 Wh	4,096 Wh
AC output	3,840 W	4,000 W
Voltage	120V / 240V	120V / 240V
Rated cycles	Up to 6,000 to 80%	See spec sheet
Max solar input	Up to 4,000 W (with SolarX 4K add-on)	See spec sheet
Price, Oct 2026	About $1,599	About $2,799 on sale (list $3,699)
Price per Wh	$1,599 ÷ 2,765 = about $0.58	$2,799 ÷ 4,096 = about $0.68

To size one of these for your house, start with your daily kWh. Our guide on how many solar batteries it takes to run a house walks through the math. If you are weighing a wired home battery instead, see our solar batteries guide.

How long will Bluetti or EcoFlow run my fridge in an outage?

Plan on about 85% of rated capacity after inverter losses. A full-size fridge averaging 150 W shows the math:

1 kWh tier: 1,024 Wh × 0.85 = 870 Wh. Then 870 ÷ 150 W = about 5.8 hours.
2 kWh tier: 2,074 Wh × 0.85 = 1,763 Wh. Then 1,763 ÷ 150 W = about 11.8 hours.

Running home circuits from a power station needs a transfer switch or interlock installed by a licensed electrician, to NEC rules and with any local permit. Never backfeed power through a wall outlet.

Frequently asked questions

Is Bluetti as good as EcoFlow?

On published specs, yes. Both use LiFePO4 cells and offer 5-year coverage on these models. Bluetti leads on solar input at 2 kWh; EcoFlow leads on weight.

Which brand has the longer warranty?

Both list 5 years on the models compared here. EcoFlow’s DELTA 3 Max reaches 5 years only after you register it in the EcoFlow app.

Can Bluetti or EcoFlow run a house?

The 1–2 kWh models run essentials for hours. For whole-home backup, look at the 120/240V Apex 300 or DELTA Pro 3, wired in through a transfer switch.

Do Bluetti and EcoFlow work with other brands’ solar panels?

Usually, yes. Keep the panel voltage inside the input range, stay under the max watts and use the right adapter cable.
