This kit pairs the EcoFlow DELTA Pro portable power station with one, two or three EcoFlow 220W bifacial portable solar panels. The DELTA Pro stores 3600Wh in an LFP battery, delivers 3600W of pure sine wave AC output at 120V and accepts up to 1600W of solar input.
It suits homeowners planning for outages, RV travelers and anyone who wants to recharge from the sun. Each panel has a 220W front side and a 155W rear side for ambient light, and it comes with a carry case that unfolds into a kickstand.



The DELTA Pro's 3600Wh, 48V LFP battery is rated for 3,500 cycles to 80% or more of its capacity. Five AC outlets share 3600W at 120V with 7200W of surge, and one of them is a 30A outlet. EcoFlow says it can power up to 15 devices at once.
X-Boost lets the DELTA Pro run a device of up to 4500W while its rated output stays at 3600W. EcoFlow says X-Boost suits heating devices, doesn't support appliances with voltage protection such as precision instruments, and isn't available while the unit is recharging in bypass mode.
Each panel has a 220W primary side and a 155W rear side that collects ambient light. EcoFlow says the rear side can capture up to 25% more solar energy, depending on the surface below the panel, and rates the panel's conversion rate at 23%.
The panels use thin, one-piece tempered glass that EcoFlow says can withstand heat up to 300°F. They are rated IP68 for water and dust, which EcoFlow defines as a maximum water depth of 1 meter for up to 24 hours.
The DELTA Pro's solar input accepts 11–150V at up to 15A and 1600W. From a wall outlet, X-Stream charging reaches 1800W and fills the battery in about 2.7 hours. Set the AC charging power from 200W to 1800W with the AC Charge Speed Switch or the EcoFlow app. It also charges from a 12V or 24V car outlet.
While plugged into the grid, the DELTA Pro switches connected devices to battery power within 30ms if the power goes out. One DELTA Pro links with up to two DELTA Pro Smart Extra Batteries, and EcoFlow lists expandable capacity from 3.6kWh to 25kWh by adding another unit, Extra Batteries and Smart Generators. Two units reach 7200W at 240V through the Double Voltage Hub or Smart Home Panel. All add-ons are sold separately.



Home backup. Keep a refrigerator, lights and electronics running through an outage, and recharge from the panels during the day. For a refrigerator holding medicine or other valuables, EcoFlow recommends setting the AC output to Always On in the app.
RV travel and camping. Set up the panels on their kickstand cases at camp and roll the DELTA Pro on its wheels and luggage-style handle.
Off-grid cabins. Store solar energy during the day and use it at night, with the Smart Generator or EV X-Stream Adapter (both sold separately) as other ways to recharge.
Professional work. Power cameras, lights and tools on location, or keep a small business running away from an outlet.



Versus the DELTA Pro alone. It is the same power station. With a standalone DELTA Pro, EcoFlow supplies the solar panel and solar charging cable separately, while this kit adds one, two or three 220W bifacial panels.
Versus single-sided panels. A standard portable panel collects light on its front only. These bifacial panels add a 155W rear side for ambient light.
Versus a gas generator. A gas generator needs fuel and maintenance and has to run outdoors. The DELTA Pro stores energy from the sun or the wall without fuel or exhaust.



This may be a good fit if



One, two or three 220W bifacial panels, depending on the option you choose.
EcoFlow rates X-Stream wall charging at up to 1800W, with a full charge in about 2.7 hours. Use a wall outlet that supplies more than 15A, or lower the charging speed with the AC Charge Speed Switch.
Yes. One DELTA Pro links with up to two DELTA Pro Smart Extra Batteries, sold separately. Turn off both units before you connect or disconnect them.
Every three months, discharge it to 0%, fully recharge it, then discharge it to 60%. EcoFlow's warranty doesn't cover a unit that hasn't been charged or discharged for more than 6 months.
The EcoFlow DELTA Pro + 220 Watt Bifacial Portable Solar Panel kit combines a 3600Wh, 3600W power station with two-sided 220W panels and up to 1600W of solar input. If you have questions about how many panels fit your home backup or travel plans, the Outbound Power team is happy to help.
