The catch
EcoFlow DELTA 3 Plus
With each solar input limited to 500W, a single input cannot take the whole 1000W headline.
Side by side
EcoFlow DELTA 3 Plus vs BLUETTI Elite 100 V2: DELTA connects two separate solar strings, with the same base reserve
Quick verdict
If the job is defined by two separately connected solar strings or two 140W USB-C devices, DELTA 3 Plus is the choice. If a compatible single solar-input arrangement and the 140W plus 100W USB-C ports are enough, Elite 100 V2 is. Both store 1024Wh and put out 1800W of ordinary AC, so those shared numbers don't pick a runtime winner. The connection plan is what separates them.
Before you buy
Why, and what it costs you
Two panel groups call for the right input layout
For a plan with two separate panel strings, DELTA 3 Plus has two inputs, each with a 500W ceiling. Elite 100 V2 has a single input of up to 1000W, so combining the panels takes a configuration that stays inside its voltage and current limits.
Where this comes from
EcoFlow has two independent physical solar inputs, rated 500W each, whereas BLUETTI has a single 12 to 60V, 20A input. Panel wattage alone does not approve any wiring topology.
The catch
BLUETTI Elite 100 V2
Physically there is just one solar input.
EcoFlow DELTA 3 Plus
- Why pick it
- Wire two panel strings into separate 500W solar inputs
- Run two devices that call for supported 140W USB-C
- The catch
- With each solar input limited to 500W, a single input cannot take the whole 1000W headline.
BLUETTI Elite 100 V2
- Why pick it
- Feed one compatible solar-input arrangement up to its 1000W limit
- Supply a 140W device and a second one within 100W
- The catch
- Physically there is just one solar input.

What this page compares
DELTA 3 Plus and Elite 100 V2 compared on separate solar strings, high-power USB-C laptops and a realistic 1kWh backup plan.
If the job is defined by two separately connected solar strings or two 140W USB-C devices, DELTA 3 Plus is the choice. If a compatible single solar-input arrangement and the 140W plus 100W USB-C ports are enough, Elite 100 V2 is. Both store 1024Wh and put out 1800W of ordinary AC, so those shared numbers don't pick a runtime winner. The connection plan is what separates them.

In practice
Differences you will notice
Two panel groups call for the right input layout
For a plan with two separate panel strings, DELTA 3 Plus has two inputs, each with a 500W ceiling. Elite 100 V2 has a single input of up to 1000W, so combining the panels takes a configuration that stays inside its voltage and current limits.
How we worked this out
EcoFlow has two independent physical solar inputs, rated 500W each, whereas BLUETTI has a single 12 to 60V, 20A input. Panel wattage alone does not approve any wiring topology.
Look at what the second workstation needs from USB-C
DELTA 3 Plus has two ports with that rating, which suits two devices that each need a compatible 140W USB-C supply. The second port on Elite 100 V2 is limited to 100W.
How we worked this out
The USB-C ratings compared are 140W plus 140W against 140W plus 100W. The devices, e-marked cables and aggregate output limits all have to support the intended use too.
An inverter rating doesn't promise an hour of energy
One hour at a steady 1500W takes 1500Wh. Each station stores 1024Wh, so neither base battery can meet that target, even before conversion losses.
How we worked this out
On either station, 1500W × 1h = 1500Wh, which is more than 1024Wh. Startup demand is still a separate check.
Option A
EcoFlow, DELTA 3 Plus
DELTA 3 Plus
This 1,024Wh station cares more about quick solar recovery and high-power USB-C than about headline battery size. Its two 500W solar inputs can each take a separate panel string.
- Best for
- Wire two panel strings into separate 500W solar inputs
Facts we checked
- Capacity, nominal, and continuous AC: 1024Wh and 1800W
- Inputs for solar: Two, each up to 500W
- Voltage windows for solar: 11 to 60V on each input
- Ratings for USB-C output: Two ports, each up to 140W
Option B
BLUETTI, Elite 100 V2
Elite 100 V2
What sets this compact 1,024Wh station apart is its 1,000W solar input, dual high-power USB-C and quiet operation under light loads.
- Best for
- Feed one compatible solar-input arrangement up to its 1000W limit
Facts we checked
- Capacity, nominal, and continuous AC: 1024Wh and 1800W
- Inputs for solar: One, up to 1000W
- Voltage windows for solar: 12 to 60V on the input
- Ratings for USB-C output: One port up to 140W, the other up to 100W
Spec by spec
Where they really differ
| Spec | EcoFlow DELTA 3 Plus | BLUETTI Elite 100 V2 | In practice |
|---|---|---|---|
| Nominal capacity and continuous AC | 1024Wh and 1800W | 1024Wh and 1800W | Equal ratings do not mean equal measured runtime or surge compatibility. |
| Solar inputs | Two inputs up to 500W each | One input up to 1000W | Both headlines give the same total, yet the allowed connection arrangement is different. |
| Solar voltage windows | 11 to 60V per input | 12 to 60V on the input | The correct input has to be satisfied by panel voltage and current, cold-weather open-circuit voltage included. |
| USB-C output ratings | Two ports up to 140W each | One up to 140W and one up to 100W | A second device that needs over 100W can be the deciding factor. |
Trade-offs
What each pick costs you
With EcoFlow DELTA 3 Plus
- Long high-load tasks still run up against the base 1024Wh battery.
With BLUETTI Elite 100 V2
- The second USB-C port cannot exceed 100W.
Change of plan
When the answer changes
Either two separate solar inputs or two 140W USB-C ports are needed
Go with EcoFlow DELTA 3 Plus. Those specific connections come with DELTA 3 Plus.
A single compliant solar input plus a second USB-C device under 100W is enough
Go with BLUETTI Elite 100 V2. That connection brief is met by Elite 100 V2, with no need for EcoFlow's additional port capability.
Decision guide
How to decide
Two separately connected solar strings or two 140W USB-C devices are the signs that DELTA 3 Plus is the right one.
Two panel groups call for the right input layout
With two separate panel strings, DELTA 3 Plus provides two inputs, each with a 500W ceiling. Elite 100 V2 has a single input of up to 1000W, so combining panels needs a configuration within its voltage and current limits. EcoFlow is the better choice when keeping the strings on separate connections makes the verified setup simpler. BLUETTI is the better choice when one compliant array is already planned. Sharing a 1000W headline does not make the wiring interchangeable.
Look at what the second workstation needs from USB-C
Two devices that each need a compatible 140W USB-C supply are covered by the two ports on DELTA 3 Plus rated for it. The second port on Elite 100 V2 tops out at 100W. EcoFlow is right if both devices need the higher PD profile and the supported total-output conditions work out. BLUETTI is right when the second device needs 100W or less. A cable labeled USB-C doesn't by itself confirm 140W capability or the required voltage profile.
An inverter rating doesn't promise an hour of energy
Holding a steady 1500W for one hour takes 1500Wh. Each station stores 1024Wh, so neither base battery gets there, and that is before conversion losses. That load could sit inside the continuous output rating and still fall short of the runtime brief.
What this page can’t tell you
- No measurement of solar yield, shade performance, runtime or noise decides a winner. Auxiliary DC charging accessories are not counted as expansion options that are missing.
