Technical comparison · Home backup
Two home LFP power stations with 10 ms UPS switchover, built to keep loads running when the grid drops. What decides is capacity: the SOLIX C2000 Gen 2 stores twice what the DELTA 3 Classic does, and weighs more for it.

The differences that matter
- 2.048 against 1.024 kWh → on the same loads the C2000 Gen 2 stays on twice as long, at the cost of 6.8 kg more.
- 2400 against 1800 W continuous → above 1800 W the DELTA 3 Classic is not enough; the C2000 Gen 2 goes to 2400 W.
- Maximum charging 2.3 against 1.4 kW → the bigger battery also refills faster from the mains.
- Warranty 5 against 3 years → the C2000 Gen 2 stays covered two years longer.

Which one to choose
Choose Anker SOLIX C2000 Gen 2 if…
you want a room-sized store that can grow: the C2000 Gen 2 expands to 4 kWh, so you start with one module and add energy if use demands it. The trade-off is 18.9 kg to move around and a declared idle draw of 9 W, which counts even when the unit sits switched on with no load.
Choose EcoFlow DELTA 3 Classic if…
the unit has to move often, between house, garage and a trip away: the DELTA 3 Classic weighs 12.1 kg, has three mains sockets and two USB-C ports, and declares a 0 to 80% recharge in 60 minutes and solar input up to 500 W. The trade-off is half the energy reserve and a warranty two years shorter.
