Capacity
DELTA 2 Max: +992 Wh (+93.9%).
This comparison targets buyers weighing a mid-capacity portable station against a high-capacity workhorse for home backup, solar setups, or running heavier appliances. The DELTA 2 Max delivers 2400W of running power and 4800W surge, nearly doubling the SOLIX C1000's 1800W and 2400W figures.
Its 2048 Wh battery holds roughly twice the energy, and it powered 45 out of 53 tested devices compared to 38 for the C1000. Solar input caps at 1000W versus 600W, giving the EcoFlow unit a clear edge for larger panel arrays.
The tradeoff is weight and portability: the C1000 checks in at 28.4 lbs, while the DELTA 2 Max tips the scale at 50.7 lbs. The C1000 also offers UPS functionality with a 20 ms switchover, a feature the DELTA 2 Max lacks.
