DELTA Max powers almost all the devices you need with a large 2400W AC output.Using 3400W X-Boost mode, power even high-wattage appliances without overloading.

Emergency backup

In the most extreme cases, use the EcoFlow Smart Generator to efficiently recharge using DC. Once DELTA Max hits a low battery level, the Smart Generator kicks in automatically, fully recharging your battery.

Harness the power of the sun

Collect up to 800W of sustainable solar energy to keep DELTA Max running even when there’s an outage. With an advanced MPPT (maximum power point tracking) algorithm, DELTA Max auto-regulates, maintaining optimal solar generation throughout the day.

Monitor & control from the EcoFlow app

Take control of your DELTA Max and quick-view stats right from your phone. Customize settings such as charging speeds and Smart Generator auto-start levels to fit your power needs.

Reliable BMS

EcoFlow’s battery management system analyzes DELTA Max’s vitals in real-time, regulating voltage, current, and temperature. BMS keeps DELTA Max safe and efficient, maintaining its life for years to come.
