Can the 220W panel charge the DELTA 3 Max on its own?

Yes. The panel plugs into the station's solar input and charges it directly. Expect slower charging in cloud, shade or low sun angles.

What can the DELTA 3 Max run at once?

It has several AC outlets plus USB and DC ports, so it can run a fridge, router, lights and charge devices together within its output limit. High-draw appliances like heaters or large microwaves will drain it quickly.

How does it compare with the DELTA 2 Max?

The DELTA 3 Max is the newer generation with updated charging electronics and LiFePO4 cells. It is a step up in recharge speed and cycle life rather than a dramatic jump in capacity.

Can I add extra batteries?

Yes. EcoFlow sells expansion batteries for the DELTA 3 series that increase total capacity. They add weight and bulk to the setup.

Is it good for home backup?

It covers essentials like a fridge, lights and router during short outages. For whole-home backup or multi-day outages, a larger system or generator is a better fit.

The bundle includes the DELTA 3 Max power station, the 220W folding solar panel and the charging cables needed to connect them.

About the EcoFlow DELTA 3 max Portable Power Station + 220W solar panel

This bundle pairs the EcoFlow DELTA 3 Max portable power station with a 220 W bifacial portable solar panel. The power station has a 2,048 Wh capacity and an AC output that can run home essentials, tools and RV appliances. It can be used for home backup, travel or off-grid power.

The DELTA 3 Max uses LiFePO₄ battery chemistry. Its inverter supports heavy-load devices, and a 10 ms automatic switchover (UPS) helps protect sensitive electronics. It can be charged from a wall outlet, a generator or solar input. It is quiet at light loads and has a rugged, portable design for mobile or fixed use.

The solar panel is a one-piece foldable design with tempered glass construction. It has two active sides: 220 W on the front and 155 W on the rear. The rear side captures reflected and ambient light, which increases total energy yield.
