Is the EcoFlow DELTA 3 Max + 400W Portable Solar Panel the Solar Setup You Need?

A power station only gets you as far as its last charge. Add solar and the EcoFlow DELTA 3 Max keeps going through a multi-day outage or a week off-grid. This kit is EcoFlow's own pairing of the two, a matched 2048Wh solar generator in one order.

Features & Performance

The power station: EcoFlow DELTA 3 Max

  • 2048Wh of storage on automotive-grade full-tab LFP (LiFePO4) cells. EcoFlow rates them for 10 years of reliable power.
  • 2400W rated AC output with 4800W surge.
  • X-Boost up to 3400W. Runs heavy-duty appliances such as coffee makers, washers and circular saws.
  • 0-80% in 68 minutes from a standard wall outlet or from a generator. It also charges from solar (up to 500W) or a car outlet.
  • 10ms auto-switch. When grid power drops, connected devices switch over fast enough that NAS drives, routers and servers keep running.
  • 25dB or quieter at 600W.
  • 4 AC outlets, 3 USB-C, 1 USB-A and a 12V car outlet. 44.8 lb (20.3 kg), 13% lighter than EcoFlow's previous 2kWh unit.
  • EcoFlow app (OASIS 3.0) over Wi-Fi and Bluetooth, with Storm Guard Mode to charge ahead of severe weather.

The panel: EcoFlow 400W Portable Solar Panel

  • 400W rated output with up to 23% conversion efficiency.
  • IP68 waterproof and dustproof rating.
  • One-piece folding design that's self-supporting, with an adjustable angle so you can face it toward the sun.
  • Durable, multi-layered construction built for repeated outdoor use.

Ideal Use Cases

  • Home backup. Keep the refrigerator, Wi-Fi, lights and phones going through an outage. The 10ms auto-switch keeps a modem or desktop from dropping when the power does.
  • RV and camping. At 25dB or quieter at 600W, it won't bother the next site over.
  • Job sites. 2400W continuous with X-Boost up to 3400W handles circular saws and other corded tools where there's no outlet to plug into.
  • Off-grid cabins and sheds. Pair it with EcoFlow solar to recharge without fuel or a grid connection.

Why Choose the DELTA 3 Max Solar Kit over the DELTA 3 Max Plus?

Both store 2048Wh. The DELTA 3 Max's 2400W covers most homes, RVs and job sites, so if your loads stay under that, this kit spends on solar rather than inverter output you won't use. EcoFlow's ratings:

Frequently Asked Questions

What do I get with the EcoFlow DELTA 3 Max + 400W Portable Solar Panel kit?

One EcoFlow DELTA 3 Max portable power station (2048Wh, 2400W) and one EcoFlow 400W Portable Solar Panel. It is not the DELTA 3 Max Plus, and there's no extra battery in the kit.

Is the DELTA 3 Max in this kit the same as the DELTA 3 Max Plus?

No. Both hold 2048Wh, but the DELTA 3 Max is rated at 2400W (4800W surge, X-Boost up to 3400W) and the Max Plus at 3000W (6000W surge, X-Boost up to 3800W). This kit contains the DELTA 3 Max.

Can the DELTA 3 Max take the full output of the 400W panel?

Yes. The DELTA 3 Max accepts up to 500W of solar (11-60V, 13A) through its XT60i port, above the panel's 400W rating. Real output depends on sunlight, panel angle and temperature.

How long will the DELTA 3 Max run a refrigerator?

As a rough guide, divide the 2048Wh capacity by the appliance's average draw. A 150W refrigerator works out to about 13 hours before conversion losses, so expect somewhat less. Solar can top it back up during the day. When you're ready, add the kit to your cart and we'll ship it to you.

The DELTA 3 Max carries EcoFlow's 3-year standard warranty, and EcoFlow adds a 2-year extension when you register the unit in the EcoFlow app. Mighty Generators is an authorized EcoFlow dealer, so your unit is a genuine, new EcoFlow product with full manufacturer warranty support.
