Combining the best - EcoFlow Delta Pro with EcoFlow’s 220W Portable Solar Panel is two in one.

With a 220W primary side and a 155W side on the back for ambient light, you can capture up to 25% more solar energy and charge your portable power station even faster.

Fully charge in 1.8 hours

EcoFlow's X-Stream charging technology is not only fast, but also safe. While charging DELTA Pro from a typical AC wall outlet in 1.8 hours*, the battery management technology ensures safety and maintains its lifespan.

Go renewable with 1600W solar charging

EcoFlow's solar products provide you with a cost-effective renewable energy source to keep you powered. DELTA Pro can be charged by solar energy in about 2.8-5.6 hours. The voltage range of DELTA Pro is 11-150V, making it compatible with 90% of third-party solar panels using MC4 connectors. When the weather changes, the smart maximum power point tracking (MPPT) adjusts automatically, ensuring that your solar generation is maximized at all times of the day.

A battery that lasts for years on end

DELTA Pro comes with a brand-new LFP battery with 6500 cycles, which means you'll be able to use it for years before it loses 50% of its original capacity. The battery management system from EcoFlow analyzes and regulates voltage, current, and temperature in real time. DELTA Pro is an exceptionally secure and efficient home battery thanks to its innovative protective mechanism.

Multiple ways to control & monitor

DELTA Pro can be controlled on the device itself, via the remote control accessory, or via the EcoFlow app, which offers a ton of customization options. You can access your power settings on the app, including charging and discharging levels, AC charge rates, Smart Generator management, and much more.
