Head-to-head
OUPES Mega 1 vs Anker SOLIX C1000: Mega adds rated output, C1000 starts with slightly more energy
The short answer
Choose Mega 1 for more rated output and solar intake. C1000 offers slightly more base energy, with both supporting compatible expansion.
Before you choose
The reasoning and the trade-offs
A common load makes the reserve easier to compare
For a steady 300W load, OUPES Mega 1 models to about 2.7 hours and Anker SOLIX C1000 to 2.8 hours.
What this is based on
Hours = nominal Wh × 0.8 / 300W. Inputs 1024Wh and 1056Wh. 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
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.

The batteries are close enough to prioritize the load
Winner by situation
Start with what you need it to do
A supported appliance needs above 1800W
Mega 1 reaches 2,000W continuous output against 1,800W for C1000. A 1,900W running load fits only the Mega rating, subject to its startup and outlet limits.
- OUPES Mega 1
- Better fit
- Anker SOLIX C1000
- Not suitable
Keep slightly more base energy
C1000 stores 1,056Wh against 1,024Wh. The 32Wh difference adds roughly five modeled minutes at 300W, so this is a small reserve advantage.
- OUPES Mega 1
- Depends
- Anker SOLIX C1000
- Better fit
The battery needs to cover a steady 300W load
The shared planning case gives 2.7 hours from OUPES Mega 1 and 2.8 from Anker SOLIX C1000. Measure actual wattage before choosing a required overnight reserve.

I want to replenish the battery with solar
The maximum input is 800W for OUPES Mega 1 and 600W for Anker SOLIX C1000. 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, OUPES Mega 1 models to about 2.7 hours and Anker SOLIX C1000 to 2.8 hours.
How we reached this conclusion
Hours = nominal Wh × 0.8 / 300W. Inputs 1024Wh and 1056Wh. 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
OUPES Mega 1 stores about 36.8 nominal watt-hours per pound, compared with 37.1 for Anker SOLIX C1000.
How we reached this conclusion
Nominal energy divided by published weight: 1024 / 27.8 and 1056 / 28.44. This compares stored energy per lifting weight, not measured efficiency or handle comfort.
The output upgrade barely changes lifting weight
Mega 1 adds 200W of continuous output and is 0.64 lb lighter than C1000, while giving up 32Wh of nominal capacity.
How we reached this conclusion
2000 - 1800 = 200W. 28.44 - 27.8 = 0.64 lb. 1056 - 1024 = 32Wh.
Choice A
OUPES, Mega 1
Mega 1
A manageable starter battery with room to grow. Its 2000W inverter can cover a short high-draw job, while two optional B2 batteries address the very different problem of making smaller loads run longer.
- Best matched use
- A small backup system that may need much more runtime later.
Checked facts
- 1024Wh capacity and 2000W continuous AC output.
- About 27.8 lb.
- Two B2 batteries increase total capacity to 5120Wh.
- 800W solar input and 1400W AC input.
- Two 100W USB-C ports and four AC outlets.
- Manufacturer lists transfer within 20ms.
Choice B
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
Meaningful differences
What changes the fit
| What changes | OUPES Mega 1 | Anker SOLIX C1000 | Why it matters |
|---|---|---|---|
| Nominal battery energy | 1024 Wh | 1056 Wh | Stored energy determines the starting runtime budget. |
| Continuous AC output | 2000 W | 1800 W | This is the sustained rating used for load screening, separate from surge and boost modes. |
| Lifting weight | 27.8 lb | 28.44 lb | Wheels help on flat ground. A trunk, step or shelf still requires a lift. |
| Maximum solar input | 800 W | 600 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 | 20 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 OUPES Mega 1
- 1024Wh will not keep a 2000W appliance running for hours.
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.
What matters in practice
How to make the call
The batteries are close enough to prioritize the load
Mega has 1,024Wh and C1000 1,056Wh. That 32Wh gap is only about five minutes at 300W under the shared planning assumption.
The continuous rating creates a real boundary
Mega reaches 2,000W against 1,800W. A 1,900W supported load fits only one rating, even though both have larger surge or boost headlines.
Charging potential depends on the planned panels
Mega lists 800W solar versus 600W. Verify voltage and current before assigning value to that extra 200W.
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.
