FAQ

Can an EcoFlow DELTA Pro Ultra Battery charge without the EcoFlow DELTA Pro Ultra Inverter?

No. The EcoFlow DELTA Pro Ultra Battery needs to be connected to an EcoFlow DELTA Pro Ultra Inverter to charge. EcoFlow DELTA Pro Ultra is not compatible with third-party inverters.

How long does it take to fully charge a battery?

The fastest charging power for one battery is 6200W. It takes about 92 minutes to charge one battery from 0% to 100%, but if stacked on two or more batteries, the maximum charging power can reach 8800W. It takes about 1 hour and 56 minutes to charge two batteries from 0% to 100%.

How do I choose between Self-powered, TOU mode, and Scheduled tasks?

"1. If you have solar panels and a stable rate plan, go for Self-powered mode. It minimizes your grid dependency. When your battery is above the backup reserve level, it charges only from solar until the charge limit is reached. 2. For manual control over charging and discharging, opt for Scheduled tasks. It works regardless of whether you have solar panels. 3. If your rate plan fluctuates and you want to optimize charging, discharging, and solar usage for savings, TOU mode is the way to go."

How do I set my electricity rate?

"You have two options for setting your electricity rate: a. Go to the device settings page and find ""Electricity rate settings"". b. Alternatively, on the Operating mode page, you'll find a shortcut to electricity rate settings within the TOU mode section."

I'm using the savings mode, but why does my battery level drop during a grid outage when it's not discharging?

When there's a grid outage and you're in savings mode, the device automatically turns on AC output to ensure your appliances stay powered. However, this consumes some battery power. If AC output remains on for an extended period, it can cause the SoC to drop.
