The differences that matter
- Capacity, about 1 kWh vs about 2 kWh, expandable to 2.1 kWh vs 10 kWh → only the DELTA can grow in a meaningful way.
- Continuous output, 1800 W vs 3000 W → appliances drawing between the two only start on the DELTA.
- Solar input, 600 W vs 1000 W → the DELTA takes more panels and recharges from the sun faster.
- Weight and warranty, 12.9 kg and 5 years vs 22.1 kg and 3 years → the C1000 is easier to carry and covered for two more years.
