Product Features

long-lasting li fepo₄ battery

Built with LFP chemistry, it offers over 3,000 full cycles—about 10 years of daily use before capacity drops to 80 %—ensuring reliability and longevity

powerful ac output with x‑boost

Delivers 2,400 W continuous power from its pure sine wave AC outputs and supports up to 3,100 W via X-Boost, capable of running nearly any household appliance.

ultra-fast dual charging

Recharge from 0 % to 80 % in as little as 43 minutes using AC + solar (up to 1,000 W combined), or about 53 minutes on AC alone. Full recharge completes in approximately 2.3 hours.

scalable storage

Supports up to two Delta 2 Max smart extra batteries, expanding capacity to roughly 6,144 Wh—ideal for extended outages and off-grid setups.

dual mppt solar input

Handles up to 1,000 W solar input across independent MPPT channels (11–100 V, ~13 A each), maximizing solar efficiency.

smart monitoring and app control

With Wi-Fi and Bluetooth, the EcoFlow app enables remote monitoring, power management, prioritization of input sources, firmware updates, and scheduling

quiet, safe, and portable

Operates at noise levels as low as 30 dB—quieter than most competitors—housed in a fire-resistant, robust casing with reinforced ports. Weighing approx 23 kg, it’s built for mobility.

uninterrupted power supply (ups)

In EPS mode, seamlessly switches to battery backup in under 20 ms during outages—ensuring no interruption for sensitive electronics.

Frequently Asked Questions

How long can the Delta 2 Max power my appliances?

Run times depend on total wattage used. With 2,048 Wh capacity, you can power a 60 W laptop for about 34 hours or a 400 W fridge for just over 5 hours. For exact device estimates, refer to the built-in estimation tool in the EcoFlow app.

Can I use the Delta 2 Max indoors safely?

Yes. It uses LiFePO₄ batteries, emits zero toxic fumes, and operates quietly—often around 30 dB—making it ideal for indoor use even overnight.

Does it support uninterrupted power supply (UPS)?

Absolutely. In EPS (emergency power supply) mode, it automatically switches to battery power in under 30 ms during outages, protecting sensitive electronics.

Can I charge and use the Delta 2 Max at the same time?

Yes. Pass-through charging is fully supported. You can draw from the unit while it’s charging via AC, solar, or combined inputs.

How fast does it recharge?

The fastest recharge is achieved with dual AC+solar: it can charge from 0 % to 80 % in just 43 minutes. Using AC alone (1,800 W), that timeframe is around 66 minutes.

How many solar panels can I connect?

The Delta 2 Max supports dual MPPT solar inputs up to a combined 1,000 W. That typically means two 400 W panels or an equivalent setup.

Is the battery expandable?

Yes. You can add up to two Delta 2 Max smart extra batteries, increasing total capacity from 2,048 Wh to as much as 6,144 Wh
