Power & Performance
EcoFlow DELTA Pro Solar Generator (PV220W)
from: EcoFlow
The EcoFlow Delta Pro outperforms in inverter power, offering 3600W continuous and up to 7200W surge. This supports larger appliances, heavy-duty tools, and dual-voltage systems with the Smart Home Panel.
In contrast, the Bluetti EP500 has a 2000W inverter, which is enough for most household appliances, but it lacks the same high-surge or dual-voltage capability.
Winner: EcoFlow Delta Pro for higher power output and flexible voltage options.
Battery Capacity & Cycle Life
Bluetti EP500 leads in base battery capacity with 5100Wh compared to Delta Pro’s 3600Wh. It also offers longer cycle life (6000+ cycles vs 3500), making it a strong choice for longevity.
However, the EcoFlow Delta Pro is expandable up to 25kWh, allowing users to scale for home backup or extended off-grid use.
Winner: Tie — Bluetti for capacity and lifespan; EcoFlow for expandability.
Output Ports & Expandability
The EcoFlow Delta Pro offers more AC ports, 240V support (when paired), and advanced modular expandability. It integrates with EcoFlow Smart Home Panel, solar tracking, and external batteries.
The Bluetti EP500 is a self-contained unit with no option for battery expansion or dual-voltage output.
Winner: EcoFlow Delta Pro
Portability & Weight
At 167 lbs, the Bluetti EP500 is significantly heavier. Both units include wheels, but the EcoFlow Delta Pro is much easier to move and transport at 99 lbs.
Winner: EcoFlow Delta Pro for better portability.
Charging Options
The EcoFlow Delta Pro has faster and more diverse charging: 1600W solar, 1800W AC, EV station charging, and dual charging options. It can charge in under 2 hours from a standard AC outlet or EV charger.
The Bluetti EP500 accepts up to 1200W solar and takes longer to recharge fully. It does not support EV charging.
Winner: EcoFlow Delta Pro
Price & Value
The EcoFlow Delta Pro starts at a lower base price ($3,699) and offers more expandability, making it a better value for scalable systems. The Bluetti EP500 costs more ($4,599) with higher initial capacity but fewer growth options.
Winner: EcoFlow Delta Pro
Final Verdict: Which Is Better?
- Choose the Bluetti EP500 if you want a high-capacity, long-life battery in a plug-and-play format with no plans to expand.
- Choose the EcoFlow Delta Pro if you value power, scalability, portability, and integration with home power systems.
For most users—especially those seeking a whole-home backup solution or RV flexibility—the EcoFlow Delta Pro offers superior performance and future-proofing.
