Main trade-off
EcoFlow DELTA 3 Plus
Each solar input is limited to 500W, so one input cannot accept the entire 1000W headline.
Head-to-head
EcoFlow DELTA 3 Plus vs BLUETTI Elite 100 V2: Same base reserve, DELTA connects two separate solar strings
The short answer
Choose DELTA 3 Plus when two separately connected solar strings or two 140W USB-C devices define the job. Choose Elite 100 V2 when a compatible single solar-input arrangement and its 140W plus 100W USB-C ports are sufficient. Both store 1024Wh and provide 1800W ordinary AC output, so those shared numbers do not establish a runtime winner. The connection plan is the stronger distinction.
Before you choose
The reasoning and the trade-offs
Two panel groups need the right input layout
If the plan uses two separate panel strings, DELTA 3 Plus supplies two inputs with a 500W ceiling on each. Elite 100 V2 instead accepts one input up to 1000W, so combining panels requires a configuration that stays inside its voltage and current limits.
What this is based on
EcoFlow has two independent physical solar inputs rated 500W each. BLUETTI has one 12 to 60V, 20A input. No wiring topology is approved solely from panel wattage.
Main trade-off
BLUETTI Elite 100 V2
There is only one physical solar input.

Winner by situation
Start with what you need it to do
Keep two solar strings on separate station inputs
EcoFlow provides two inputs. BLUETTI requires a verified single-input array arrangement.

- Caution
Use two compatible 140W USB-C devices
BLUETTI's second USB-C port tops out at 100W.

What matters in practice
The differences that matter
Two panel groups need the right input layout
If the plan uses two separate panel strings, DELTA 3 Plus supplies two inputs with a 500W ceiling on each. Elite 100 V2 instead accepts one input up to 1000W, so combining panels requires a configuration that stays inside its voltage and current limits.
How we reached this conclusion
EcoFlow has two independent physical solar inputs rated 500W each. BLUETTI has one 12 to 60V, 20A input. No wiring topology is approved solely from panel wattage.
Check the second workstation's USB-C demand
For two devices that each need a compatible 140W USB-C supply, DELTA 3 Plus provides two ports with that rating. Elite 100 V2's second port is limited to 100W.
How we reached this conclusion
The compared USB-C ratings are 140W plus 140W versus 140W plus 100W. Devices, e-marked cables and aggregate output limits must also support the intended use.
The inverter rating is not a one-hour energy promise
A 1500W steady load would need 1500Wh for one hour. Both stations store 1024Wh, so neither can meet that target from the base battery even before conversion losses.
How we reached this conclusion
1500W × 1h = 1500Wh, greater than 1024Wh on either station. Startup demand remains a separate check.
Choice A
EcoFlow, DELTA 3 Plus
DELTA 3 Plus
A 1,024Wh station that puts fast solar recovery and high-power USB-C ahead of headline battery size. Two 500W solar inputs can feed separate panel strings.
- Best matched use
- Connect two panel strings to separate 500W solar inputs
Checked facts
- Nominal capacity and continuous AC: 1024Wh and 1800W
- Solar inputs: Two inputs up to 500W each
- Solar voltage windows: 11 to 60V per input
- USB-C output ratings: Two ports up to 140W each
Choice B
BLUETTI, Elite 100 V2
Elite 100 V2
A compact 1,024Wh station distinguished by 1,000W solar input, dual high-power USB-C and quiet light-load operation.
- Best matched use
- Use one compatible solar-input arrangement up to its 1000W limit
Checked facts
- Nominal capacity and continuous AC: 1024Wh and 1800W
- Solar inputs: One input up to 1000W
- Solar voltage windows: 12 to 60V on the input
- USB-C output ratings: One up to 140W and one up to 100W
Meaningful differences
What changes the fit
| What changes | EcoFlow DELTA 3 Plus | BLUETTI Elite 100 V2 | Why it matters |
|---|---|---|---|
| Nominal capacity and continuous AC | 1024Wh and 1800W | 1024Wh and 1800W | Shared ratings do not establish equal measured runtime or surge compatibility. |
| Solar inputs | Two inputs up to 500W each | One input up to 1000W | The total headline is the same but the allowed connection arrangement differs. |
| Solar voltage windows | 11 to 60V per input | 12 to 60V on the input | Panel voltage and current must satisfy the correct input, including cold-weather open-circuit voltage. |
| USB-C output ratings | Two ports up to 140W each | One up to 140W and one up to 100W | A second device needing more than 100W can make the difference. |
What you give up
Every choice has a cost
If you choose EcoFlow DELTA 3 Plus
- The base 1024Wh battery still constrains long high-load tasks.
If you choose BLUETTI Elite 100 V2
- The second USB-C port is limited to 100W.
Recommendation switch
The decision flips if...
Two separate solar inputs or two 140W USB-C ports are required
Choose EcoFlow DELTA 3 Plus. DELTA 3 Plus supplies those specific connections.
One compliant solar input and a second USB-C device below 100W are sufficient
Choose BLUETTI Elite 100 V2. Elite 100 V2 meets that connection brief without needing EcoFlow's additional port capability.
What matters in practice
How to make the call
Choose DELTA 3 Plus when two separately connected solar strings or two 140W USB-C devices define the job.
Two panel groups need the right input layout
If the plan uses two separate panel strings, DELTA 3 Plus supplies two inputs with a 500W ceiling on each. Elite 100 V2 instead accepts one input up to 1000W, so combining panels requires a configuration that stays inside its voltage and current limits. Choose EcoFlow when keeping the strings separately connected simplifies the verified setup. Choose BLUETTI when one compliant array is already planned. A shared 1000W headline does not make the wiring interchangeable.
Check the second workstation's USB-C demand
For two devices that each need a compatible 140W USB-C supply, DELTA 3 Plus provides two ports with that rating. Elite 100 V2's second port is limited to 100W. Choose EcoFlow if both devices genuinely require the higher PD profile and the supported total-output conditions fit. Choose BLUETTI when the second device needs 100W or less. A cable marked USB-C does not itself confirm 140W capability or the required voltage profile.
The inverter rating is not a one-hour energy promise
A 1500W steady load would need 1500Wh for one hour. Both stations store 1024Wh, so neither can meet that target from the base battery even before conversion losses. The same load might fit the continuous output rating while still missing the runtime brief.
What this comparison cannot tell you
- No solar-yield, shade-performance, runtime or acoustic measurement establishes a winner. Auxiliary DC charging accessories are not treated as absent expansion options.
