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.
Head-to-head
EcoFlow DELTA 3 Plus vs Anker SOLIX C1000 Gen 2: Anker runs higher steady loads, neither starts with more reserve
The short answer
Choose DELTA 3 Plus if battery expansion or two solar inputs are important. Choose C1000 Gen 2 if you carry the station often or need a steady AC load between 1800W and 2000W. Both store 1024Wh, so the Anker’s larger inverter does not provide more reserve and EcoFlow’s Plus name does not mean a larger base battery.
Before you choose
The reasoning and the trade-offs
The extra 200W can change a clear appliance decision
At a steady 1900W, EcoFlow is 100W over its rating while Anker has 100W of rated total headroom.
What this is based on
1900 − 1800 = 100W and 2000 − 1900 = 100W. This excludes startup surge and individual outlet constraints.
Main trade-off
Anker SOLIX C1000 Gen 2
Unlike the first-generation C1000, Gen 2 does not accept an expansion battery and has no built-in light.
EcoFlow DELTA 3 Plus
- Choose it for
- You want to add a compatible expansion battery later.
- You want two solar inputs with up to 1000W combined or two 140W USB-C ports.
- Main trade-off
- 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.
Anker SOLIX C1000 Gen 2
- Choose it for
- You need continuous AC headroom above 1800W.
- You want to save 2.7 lb and are happy with fixed capacity.
- Main trade-off
- Unlike the first-generation C1000, Gen 2 does not accept an expansion battery and has no built-in light.
About this comparison
Compare EcoFlow DELTA 3 Plus and Anker C1000 Gen 2 by expansion, two-input solar charging, carry weight and continuous appliance limits.
EcoFlow favors a growing solar setup, while Anker favors carrying less and running a slightly larger steady load.

What matters in practice
The differences that matter
The extra 200W can change a clear appliance decision
At a steady 1900W, EcoFlow is 100W over its rating while Anker has 100W of rated total headroom.
How we reached this conclusion
1900 − 1800 = 100W and 2000 − 1900 = 100W. This excludes startup surge and individual outlet constraints.
EcoFlow offers two thirds more total solar acceptance
Its 1000W combined ceiling is about 66.7% above Anker’s 600W ceiling.
How we reached this conclusion
(1000 − 600) ÷ 600 × 100 = 66.7%. EcoFlow requires input on both 500W channels to reach the combined maximum.
Anker is nearly 10% lighter without giving up nominal reserve
Its 24.9 lb weight is about 9.8% below the DELTA 3 Plus’s 27.6 lb.
How we reached this conclusion
(27.6 − 24.9) ÷ 27.6 × 100 = 9.8%. Both retain 1024Wh of nominal base capacity.
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.

Choice B
Anker SOLIX, C1000 Gen 2
C1000 Gen 2
A 24.9-pound 1,024Wh station with a 2,000W inverter, 140W USB-C and a 49-minute app-enabled fast-charge mode.

Meaningful differences
What changes the fit
| What changes | EcoFlow DELTA 3 Plus | Anker SOLIX C1000 Gen 2 | Why it matters |
|---|---|---|---|
| Battery capacity | 1024Wh | 1024Wh | The starting nominal reserve is the same. |
| Continuous AC output | 1800W | 2000W | Anker allows another 200W of steady combined demand. |
| Expansion battery support | Supported with compatible EcoFlow batteries | No expansion battery support | EcoFlow has a route to longer reserve. |
| Maximum solar input | 1000W across two 500W inputs | 600W through one input | EcoFlow offers more solar acceptance and a second independently controlled feed. |
| Listed weight | About 27.6 lb | 24.9 lb | Anker saves about 2.7 lb. |
| High-power USB-C | Two up to 140W | One up to 140W | EcoFlow has an additional high-power USB-C connection. |
What you give up
Every choice has a cost
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.
If you choose Anker SOLIX C1000 Gen 2
- The 49-minute mode must be enabled in the app and increases charging noise and electrical demand.
What matters in practice
How to make the call
Choose EcoFlow for how the system will grow and Anker for the load you need to run today.
The 1900W load test is straightforward
A steady combined AC demand of 1900W exceeds DELTA 3 Plus’s 1800W rating and fits below C1000 Gen 2’s 2000W rating. That makes Anker the relevant choice for that specific job. Check individual outlet ratings and startup demand as well. EcoFlow’s X-Boost mode is not treated as a substitute for the rated continuous supply.
EcoFlow’s advantage grows with the charging plan
DELTA 3 Plus provides two solar inputs and compatible battery expansion. Together they make sense for a system that will need more daily reserve and more time off-grid. The Anker stays at 1024Wh. A buyer who always returns home to recharge may never need those EcoFlow features and can prioritize the lighter station instead.
Equal capacity keeps the everyday runtime question honest
Both batteries hold 1024Wh. Without comparable discharge testing, neither brand should receive a runtime win from the nominal specifications. Their useful differences are the appliances they can support, the connections available and whether more battery can be added. Start with those concrete needs, then compare the current offers for the exact models.
What this comparison cannot tell you
- Solar ceilings do not guarantee constant input or recharge times.
- No measured efficiency or battery longevity ranking is claimed.
