Rapid Dual Charging - X-Stream tech means that DELTA Pro charges 7 times faster than the competition. That’s 0–80% in just 50 minutes and 0-100% in 80 minutes with AC input. Plug in EcoFlow solar panels and charge in as fast as 2.5 hours with 4 x 400W rigid solar panels.

400W Rigid Solar Panel

Fast Charging - With a high conversion efficiency rate of up to 23%, the 400W panel charges your LFP batteries faster than similar-sized solar panels. 

Weatherproof & Durable - The rigid panel balances design with robust materials allowing the panel to weather any storm while offering the same excellent performance and aesthetics for years. 

Off & On-grid Solution - This high-wattage panel works for both on-grid and off-grid solar-powered setups, storing energy for outages, reducing power bills, or powering an off-grid home. 

Universally Compatible - The 400W solar panel includes a 300mm charging cable that gives you plenty of space, maximizing solar input. With an all-inclusive solar connector, the 400W rigid panel works with other 3rd party solar systems and power stations.

Frequently Asked Questions

When charging DELTA Pro and its extra battery together, you can reach 6500W max charging speeds by combining AC, solar and Smart Generator methods. For DELTA Pro single unit, you can recharge it at standard wall outlets (2900W max), at EV station (3400W max)/Smart Home Panel (3000W max).
It depends on the combined voltage and current of the solar panels you choose. It's fine as long as the solar panels use solar connectors and their combined voltage and current are within 11-150 volts and under 15 amps.
First of all, make sure your DELTA Pro is connected to the EcoFlow App using Internet mode. Secondly, go to the Firmware section in the Setting of the DELTA Pro you're looking to upgrade. Check for the latest firmware and follow the steps to finish the upgrade.

Plug directly into an AC wall outlet and make sure that the wall output current is more than 15A. Otherwise, reduce the unit charging speed with the AC Charge Speed Switch. EcoFlow takes no responsibilities for any consequences caused by failures to follow instructions, including but not limited to charging with other AC charging cables.
