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 Plus: DELTA takes two solar inputs, original C1000 stores slightly more
The short answer
Choose DELTA 3 Plus for two solar inputs and a faster transfer limit. The original C1000 has slightly more stored energy at a similar weight.
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 Plus 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 Plus
The 1,800W continuous inverter is lower than C1000 Gen 2 despite a similar 1kWh battery. X-Boost does not change that normal output limit.

The extra capacity is too small to dominate
Winner by situation
Start with what you need it to do
Keep slightly more energy in the base battery
C1000 has 1,056Wh against 1,024Wh. In the 300W planning example, that is about five extra minutes, so input layout is a more useful deciding factor.
- Anker SOLIX C1000
- Better fit
- EcoFlow DELTA 3 Plus
- Depends
Build a two-input solar setup
DELTA 3 Plus reaches 1,000W through two 500W inputs. One large panel connection does not automatically unlock the combined rating. C1000 lists 600W total.

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 Plus. Measure actual wattage before choosing a required overnight reserve.

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 Plus 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 Plus.
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 larger solar ceiling is not a larger base battery
DELTA 3 Plus raises maximum solar intake by about 67% over C1000, while C1000 retains about 3% more nominal battery capacity.
How we reached this conclusion
(1000 / 600 - 1) × 100 = 66.7%. (1056 / 1024 - 1) × 100 = 3.1%. DELTA solar total requires both inputs.
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 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
- Daily solar use and laptop-heavy backup
Checked facts
- 1,024Wh LFP battery and 1,800W rated AC output
- About 27.6 lb with two 140W USB-C ports and sub-10ms transfer
- Two 500W solar inputs with 11–60V windows and supported expansion to roughly 5kWh
Meaningful differences
What changes the fit
| What changes | Anker SOLIX C1000 | EcoFlow DELTA 3 Plus | 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 | 1000 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 Plus
- The IP65 rating covers the battery pack, not permission to operate the entire station in rain. Expansion batteries and alternator hardware are separate.
What matters in practice
How to make the call
The extra capacity is too small to dominate
C1000 has 1,056Wh against 1,024Wh. In the 300W planning example, that is about five extra minutes, so input layout is a more useful deciding factor.
The solar upgrade has a condition
DELTA 3 Plus reaches 1,000W through two 500W inputs. One large panel connection does not automatically unlock the combined rating. C1000 lists 600W total.
Both can grow, but within their own systems
Each supports compatible expansion batteries. Compare the complete future battery and cable plan, because matching watt-hours does not make accessories interchangeable.
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.
