Power & Performance
EcoFlow DELTA Pro Solar Generator (PV220W)
from: EcoFlow
The EcoFlow Delta Pro delivers significantly more power with a 3600W inverter (7200W surge), compared to the Delta Max’s 2400W (5000W surge). This makes the Pro ideal for whole-home backup or heavy-duty off-grid loads.
Both units can power most household appliances, but the Delta Pro is better suited for high-demand devices like dryers or large HVAC systems.
Battery Capacity & Cycle Life
With a 3600Wh LiFePO4 battery, the Delta Pro more than doubles the capacity of the Delta Max’s 2016Wh NCM battery. The Pro also boasts over 3500 charge cycles to 80% capacity—compared to just 800 cycles for the Max.
If long-term durability is a priority, especially for daily or off-grid use, the Delta Pro is the superior choice.
Output Ports & Expandability
Both models offer multiple AC, USB-A, USB-C, and DC ports. However, Delta Pro supports more advanced configurations:
- 240V split phase support (when paired)
- EV charging compatibility
- Smart Home Panel integration
The Delta Max can expand to 6048Wh with two extra batteries, while the Delta Pro can reach a massive 25kWh, making it more scalable for large setups.
Portability & Weight
EcoFlow DELTA Max Portable Power Station
from: EcoFlow
Weighing 48 lbs, the Delta Max is significantly lighter than the 99 lb Delta Pro. It’s easier to transport and more suitable for RVs, vanlife, or weekend camping.
The Delta Pro includes built-in wheels and a telescopic handle to help offset its bulk, but it’s still best as a semi-stationary home or jobsite unit.
Charging Options
The Delta Pro supports:
- 1600W solar input
- 1800W AC input
- EV charging (Level 2)
- Dual charging (AC + solar)
Meanwhile, the Delta Max caps at 800W solar and lacks EV compatibility. Both models use EcoFlow’s X-Stream fast charging tech, but the Delta Pro is more versatile across different energy sources.
Price & Value
The EcoFlow Delta Max is more budget-friendly, often retailing around $1,599 (base unit). The Delta Pro starts around $3,699, but brings higher power, longer lifespan, and more expandability.
Choose the Delta Max if you want great value for moderate power needs. Go for the Delta Pro if you need a future-proof, heavy-duty solar generator.
Final Verdict: Which One Should You Choose?
- Choose the EcoFlow Delta Max if you want a portable, cost-effective power station for camping, light backup, or RV life.
- Choose the EcoFlow Delta Pro if you need long-term reliability, higher power output, more solar input, and full home integration potential.
FAQs
Can I use the Delta Max for home backup?
Yes, for light to moderate loads like refrigerators, routers, and lights. For full home backup or heavy appliances, the Delta Pro is better.
Is the EcoFlow Delta Pro worth the extra cost?
If you need high-capacity energy storage, 240V output, or long cycle life, the Delta Pro offers better long-term value.
Do both models support solar charging?
Yes, both support solar panels, but the Delta Pro accepts twice the solar input (1600W vs. 800W).
Can I control these units with an app?
Yes, both models include Wi-Fi and Bluetooth for remote control via the EcoFlow mobile app.
