Main trade-off
Anker SOLIX C1000
It is heavier and has a lower continuous AC rating than C1000 Gen 2. The generations do not share the same expansion path.
Head-to-head
Anker SOLIX C1000 vs EcoFlow DELTA 3: DELTA shortens transfer time, C1000 starts with slightly more energy
The short answer
Choose DELTA 3 for the shorter transfer specification. C1000 has a little more capacity and solar intake, with both supporting expansion.
Before you choose
The reasoning and the trade-offs
A common load makes the reserve easier to compare
For a steady 300W load, Anker SOLIX C1000 models to about 2.8 hours and EcoFlow DELTA 3 to 2.7 hours.
What this is based on
Hours = nominal Wh × 0.8 / 300W. Inputs 1056Wh and 1024Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
Main trade-off
EcoFlow DELTA 3
One 500W solar input cannot make use of the Plus model 1000W two-input setup.

- Choose it for
- Use up to 600W of compatible solar
- Keep a little more base battery energy
- Main trade-off
- It is heavier and has a lower continuous AC rating than C1000 Gen 2. The generations do not share the same expansion path.
EcoFlow DELTA 3
- Choose it for
- Prioritize a 10ms transfer limit
- Prefer a slightly lighter cabinet
- Main trade-off

The energy gap is small
Winner by situation
Start with what you need it to do
Use a solar input above 500W and up to 600W
C1000 accepts up to 600W of compatible solar input against 500W for DELTA 3. The panels must also satisfy voltage and current limits.
- Anker SOLIX C1000
- Better fit
- EcoFlow DELTA 3
- Not suitable
Prioritize a 10ms transfer limit
DELTA 3 publishes a 10ms transfer limit against 20ms for C1000. Test the connected equipment because a transfer specification alone does not guarantee uninterrupted operation.
- Anker SOLIX C1000
- Not suitable
- EcoFlow DELTA 3
- Better fit
The battery needs to cover a steady 300W load
The shared planning case gives 2.8 hours from Anker SOLIX C1000 and 2.7 from EcoFlow DELTA 3. Measure actual wattage before choosing a required overnight reserve.

I want to replenish the battery with solar
The maximum input is 600W for Anker SOLIX C1000 and 500W for EcoFlow DELTA 3. Compare your actual panel strings with the voltage and current limits as well as this total.

What matters in practice
The differences that matter
A common load makes the reserve easier to compare
For a steady 300W load, Anker SOLIX C1000 models to about 2.8 hours and EcoFlow DELTA 3 to 2.7 hours.
How we reached this conclusion
Hours = nominal Wh × 0.8 / 300W. Inputs 1056Wh and 1024Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
What you gain for each pound carried
Anker SOLIX C1000 stores about 37.1 nominal watt-hours per pound, compared with 37.1 for EcoFlow DELTA 3.
How we reached this conclusion
Nominal energy divided by published weight: 1056 / 28.44 and 1024 / 27.6. This compares stored energy per lifting weight, not measured efficiency or handle comfort.
A 100W solar step for a very small energy step
C1000 accepts 20% more maximum solar input than DELTA 3 while storing only about 3% more nominal energy.
How we reached this conclusion
(600 / 500 - 1) × 100 = 20%. (1056 / 1024 - 1) × 100 = 3.1%.
Choice A
Anker SOLIX, A1761
C1000
The original C1000 pairs 1,056Wh with an 1,800W inverter and accepts a matching expansion battery. It remains useful if growing the battery matters more than trimming weight.
- Best matched use
- A compact backup system with room to add capacity
Checked facts
- 1,056Wh LFP battery and 1,800W rated AC output
- About 28.44 lb, six AC outlets and 100W USB-C
- Supports a matching 1,056Wh expansion battery, up to 600W solar and a 20ms transfer mode
Choice B
EcoFlow, DELTA 3
DELTA 3
The expandable DELTA 3 for buyers who do not need the Plus model extra solar input. The battery and inverter are the same size, so the simpler charging setup can be entirely sufficient.
- Best matched use
- Home essentials and camping loads with a moderate solar array.
Checked facts
- 1024Wh battery and 1800W rated AC output.
- About 27.6 lb.
- One 500W solar input with an 11V to 60V range.
- Two 100W USB-C ports and six AC outlets.
- Compatible DELTA-series expansion batteries supported.
- Under-10ms transfer and 1500W AC charging.
Meaningful differences
What changes the fit
| What changes | Anker SOLIX C1000 | EcoFlow DELTA 3 | Why it matters |
|---|---|---|---|
| Nominal battery energy | 1056 Wh | 1024 Wh | Stored energy determines the starting runtime budget. |
| Continuous AC output | 1800 W | 1800 W | This is the sustained rating used for load screening, separate from surge and boost modes. |
| Lifting weight | 28.44 lb | 27.6 lb | Wheels help on flat ground. A trunk, step or shelf still requires a lift. |
| Maximum solar input | 600 W | 500 W | The panel voltage, current and per-port limits must also fit. |
| Dedicated battery expansion | Supported with compatible equipment | Supported with compatible equipment | Charging from an external source is different from integrated battery expansion. |
| Published transfer limit | 20 ms | 10 ms | Verify the exact connected device. A short transfer specification does not guarantee uninterrupted operation for every load. |
What you give up
Every choice has a cost
If you choose Anker SOLIX C1000
- The 600W solar ceiling requires the right panel voltage. Below 32V the input-current limit is 10A, rising to 12.5A from 32V to 60V.
If you choose EcoFlow DELTA 3
- USB-C is limited to 100W per port rather than 140W.
What matters in practice
How to make the call
The energy gap is small
C1000 adds 32Wh, which yields roughly five modeled minutes at 300W. This is a close capacity comparison rather than a full runtime upgrade.
Existing accessories can settle the choice
Both expand within their own compatible systems. A buyer who already has a supported battery should compare the complete system cost before replacing the main unit.
Separate UPS timing from marketing labels
DELTA 3 lists 10ms and C1000 20ms. Test the exact computer or network setup before relying on either for work that cannot tolerate a restart.
What this comparison cannot tell you
- Runtime figures are planning estimates from published capacity, not hands-on discharge tests.
- Do not connect a station to home wiring without approved transfer equipment and qualified installation. A battery station is not a medical continuity guarantee.
