Frequently Asked Questions

What is the base capacity and can it be expanded?

The Delta Pro starts with a 3,600 Wh LiFePO₄ battery and can be expanded up to 25 kWh by adding Smart Extra Batteries, a second Delta Pro (using a Double Voltage Hub), and/or Smart Home Panel integration.

How fast can the Delta Pro recharge?

Using EcoFlow MultiCharge (combining AC, solar, and generator), it can recharge to 80 % in around 1.8 hours. AC-only or EV station charging provides up to 3,400 W input.

Can it power my entire home during a blackout?

Yes—by linking two Delta Pros with a Double Voltage Hub, users can achieve up to 7.2 kW continuous output (14.4 kW surge), supporting a broad range of household appliances.

Does the Delta Pro support solar charging?

Yes. It accepts up to 1,600 W of solar input (11–150 V, 15 A per unit). When chained, two units can handle 3,200 W total.

Can I charge and discharge at the same time?

Yes. Through pass-through and MultiCharge, the Delta Pro can power loads and recharge simultaneously from AC, solar, EV station, or generator.

Is it safe and suitable for indoor use?

Yes. LiFePO₄ batteries emit no fumes and operate quietly. With optional Smart Home Panel, it delivers seamless, under-30 ms switchover for uninterrupted indoor backup

Can it charge electric vehicles?

Yes. It supports Level 1 and Level 2 EV charging via the EV X‑Stream Adapter, offering up to 3,400 W from EV stations.

Should I avoid storing it fully charged?

While designed for durability, for long-term storage it’s recommended to keep the battery at 70–90 % state of charge and maintain it in a cool environment to preserve battery health.
