The differences that matter
- 1.056 vs 2.048 kWh, expandable to 2.112 and 6.144 kWh → the DELTA 2 Max starts with twice the energy and can grow much further.
- 1800 vs 2400 W continuous, peak 2400 vs 4800 W → the DELTA 2 Max has more headroom both for loads running together and for peaks.
- Solar input 600 vs 1000 W, charging 1.3 vs 2.4 kW → the DELTA 2 Max accepts more charging power.
- UPS vs EPS → the SOLIX is classed as continuous power, the DELTA 2 Max as backup with a brief pause.
Which one to choose
Choose Anker SOLIX C1000 if…
you want a reserve of about 1 kWh for a few appliances, with gapless switchover for anything that cannot tolerate interruptions, and one you can move easily. You accept less energy, less power and a narrower solar input.
Choose EcoFlow DELTA 2 Max if…
you use it as home backup for bigger loads and more panels, and want room to grow past the initial 2 kWh. The trade-off is nearly twice the weight and a brief interruption when it switches to battery (EPS).
