With its 3600Wh LFP battery and 3600W continuous output, it delivers reliable power for everything from home backup during outages to extended camping trips and RV adventures. The X-Boost technology intelligently expands output to 4500W, allowing you to run demanding appliances that typically require higher wattage, while the expandable battery architecture lets you scale capacity from 3.6kWh up to 25kWh as your needs evolve.
What truly sets the DELTA Pro apart is its charging flexibility and speed. The X-Stream charging system fully recharges the battery in just 1.8 hours using a 240V outlet, 2.7 hours with standard 1800W wall power, or 2.8 hours with solar panels. This five-way charging capability (EV charging, solar, wall outlets, smart generators, or car outlets) ensures you can restore power almost anywhere. The 15 different output ports including five AC outlets, dual USB-C with 100W output, and multiple DC connections mean you can simultaneously power numerous devices without compromise.
The integrated smart app control transforms how you manage energy consumption. Monitor real-time charge levels, temperature, and charging times while customizing settings for battery longevity and optimal power distribution. For homeowners considering renewable energy, the system qualifies for a potential 30% federal Residential Clean Energy Credit, making it a financially smarter investment. The DELTA Pro represents a serious commitment to energy independence, ideal for those prioritizing reliability and future-proofing their power infrastructure.

Charging Guide
Wall Charging (Fastest Residential Option)
Connect to a 240V outlet for the quickest full recharge at 1.8 hours. Standard 120V outlets take 2.7 hours. Both methods are ideal for home backup systems and overnight charging.
Solar Charging
Pair with four 400W solar panels to achieve 2.8-hour full recharge in optimal sunlight conditions. The 23% solar conversion efficiency is industry-leading, making this the best solar generator option for off-grid living and remote locations.
EV Station & Car Charging
Leverage EV charging stations or your vehicle's power outlet to recharge on the road. Perfect for RV trips and emergency situations where traditional power isn't available.
Smart Generator Pairing
Connect EcoFlow's compatible smart generators for continuous charging during extended outages or off-grid scenarios where solar and wall power aren't accessible.
