Anker SOLIX C2000 vs EcoFlow DELTA Pro: side by side
Both sides are LiFePO4 power stations sold as bundles. The two C2000 Gen 2 examples state 2048Wh or 4096Wh with 2400W rated and 4000W peak output, and both state 5 years of warranty. The two DELTA Pro 3 examples state 4096Wh or 8kWh with 4000W output (6000W with X-Boost, scalable to 12000W) and 120/240V voltage, and both state a 5 Year Manufacturer warranty. The stated differences decide the pick. Specifications are manufacturer rated as listed, collected 21 October 2026.
| C2000 vs DELTA Pro | DELTA Pro 3 + Extra Battery | DELTA Pro 3 + 400W Panel | SOLIX C2000 + BP2000 Battery | SOLIX C2000 + Alt Charger | Amazon |
|---|---|---|---|---|---|
| Capacity stated | 8kWh | 4096Wh | 4096Wh | 2048Wh | |
| AC output stated | 4000W | 4000W | 2400W | 2400W | |
| Peak stated | 12000W | 6000W | 4000W | 4000W | |
| Voltage stated | 120/240V | 120/240V | Not stated | Not stated | |
| Solar Score | 77 | 75 | 72 | 70 | |
| Warranty stated | 5 Year Manufacturer | 5 Year Manufacturer | 5 years | 5 years |
Power output
Output separates the two sides clearly. Both DELTA Pro 3 examples state 4000W AC output with 6000W through X-Boost, and the extra-battery example’s spec table states 12000W starting wattage; both state 120/240V voltage. Both C2000 Gen 2 examples state 2400W rated and 4000W peak, with no voltage stated. On the stated figures, the DELTA Pro side runs more and bigger appliances. For more on the EcoFlow side, see our best solar panel for EcoFlow picks.
Capacity and expansion
Base capacity is close at the top: the C2000 expansion-battery bundle and the DELTA Pro 3 panel bundle both state 4096Wh. Expansion is not close. Both DELTA Pro 3 examples state expansion to 48kWh with extra batteries, while both C2000 examples state expansion to 4kWh. The alt-charger C2000 example starts at 2048Wh, and the extra-battery DELTA Pro 3 example starts at 8kWh. For a bigger system, the DELTA Pro ceiling wins outright on the stated figures.
Charging speed
Both C2000 Gen 2 examples state 80% in 45 minutes and 100% in 58 minutes with AC and solar, plus six recharge routes. The DELTA Pro 3 examples state seven unique and eighteen combo charging methods but no charge time. On the stated figures, the C2000 side wins charging speed by being the only side that states one.
What the listings leave unclear
Weight is hard to compare: the C2000 examples state weight in kilograms (34.2 kg and 18.9 kg) while the DELTA Pro examples state it in pounds (150 lb and 188 lb), and neither side states both. Noise is one-sided: the DELTA Pro 3 states 30 dB X-Quiet operation, and the C2000 examples state no noise figure. Backup switching is one-sided too: the DELTA Pro 3 states 10 ms switch-over for NAS and servers, and the C2000 examples state no figure. Where only one side states a spec, treat it as stated on that side and unstated on the other, not as a loss.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. All four examples state a five-year term, so warranty separates nobody here. Safety follows the stated build: the DELTA Pro examples state IP65-rated CTC battery pack technology with automotive-grade LFP cells, and the C2000 examples state an IP67-rated design for the panels. Performance follows stated output and capacity, which is why the DELTA Pro side scores higher. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| DELTA Pro 3 + Extra Battery | 9.7 | 32 | 21 | 21 | 6 | 2 |
| DELTA Pro 3 + 400W Panel | 9.6 | 30 | 20 | 21 | 6 | 2 |

| SOLIX C2000 + Alt Charger | 9.5 | 26 | 20 | 21 | 5 | 2 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
