Anker SOLIX C1000 vs EcoFlow DELTA 3 Classic
Technical comparison · Home backup
Capacity (1.056 and 1.024 kWh) and continuous power (1800 W) are practically the same, so the choice is not about size. What counts is the warranty (5 years vs 3), the declared peak (2400 vs 3000 W) and the switchover time (20 vs 10 ms), all manufacturer-declared values.

The differences that matter
- Warranty 5 years vs 3 → the Anker is covered two years longer at the same capacity.
- Peak 2400 W vs 3000 W → it matters for appliances with a start-up surge, not for the continuous load, which is the same (1800 W).
- Switchover 20 ms vs 10 ms → the EcoFlow moves to battery faster when the grid drops.
- Temperature range -20 to 40 °C vs -10 to 45 °C → the Anker declares a lower minimum, the EcoFlow a higher maximum.
Which one to choose
Choose Anker SOLIX C1000 if…
you want the longer cover, 5 years, with up to 600 W of panels and a declared minimum temperature of -20 °C. You accept a 2400 W peak, a 20 ms switchover and a maximum temperature of 40 °C.
Choose EcoFlow DELTA 3 Classic if…
you run appliances with a stronger start-up draw, with declared peaks of 3000 W, and you want a 10 ms switchover and grid charging at 1.4 kW. You accept a 3-year warranty, 500 W of solar input and a minimum temperature of -10 °C.
