The EcoFlow DELTA Pro 3 isn’t your average power station — it’s a smart, expandable energy system built to handle daily life, road trips, and full home backup. It gives you clean, silent power that you can charge from the wall, the car, or the sun. Once you try it, it’s hard to go back to noisy gas generators.
A Quick Look at What It Can Do
- Runs high-demand appliances like refrigerators, sump pumps, and power tools.
- Expands with extra batteries or solar panels for longer runtimes.
- Connects to your home through the Smart Home Panel 2 for automatic backup.
- Charges faster than any comparable solar generator on the market.
Check out the new How To guide below on the Delta 3 Pro. This answers a lot of the questions we get from customers.
How to Use Your EcoFlow DELTA Pro 3
You don’t need to be an electrician to get started. Here’s a simple, real-world walkthrough for using your new DELTA Pro 3 confidently and safely.
1. Charge It Up
Plug into a standard wall outlet using the included AC cord. It’ll reach a full charge quickly — you can watch the progress right on the display. A full first charge helps calibrate the battery for best long-term health.
2. Plug In Your Gear
Once charged, connect what you need — from laptops and lights to coffee makers or small appliances. The display shows how much power you’re drawing, so you’ll always know what’s running and for how long.
3. Track Everything on the Screen or App
The built-in screen keeps you updated in real time, and the EcoFlow app lets you control settings, check charge status, or view solar input even when you’re not nearby.
4. Go Solar or Charge on the Road
Connect EcoFlow solar panels directly to the unit and let sunlight keep it topped off all day. Traveling? Use the car charging cable while driving to stay ready when you arrive.
5. Set Up Home Backup (Optional)
Pair it with the Smart Home Panel 2 for seamless backup power. When the grid goes out, the DELTA Pro 3 automatically kicks in to keep essentials like lights, Wi-Fi, and refrigerators running — no noise, no fumes.
6. Keep It in Shape
If you’re storing it for a while, charge it to about 60 percent and keep it somewhere cool and dry. A quick top-off every few months keeps the battery ready for action.
Pro Tip: The DELTA Pro 3 is modular — add extra batteries, solar panels, or the EV-level alternator charger to create a setup tailored to your lifestyle.
Why People Love the DELTA Pro 3
It’s quiet, powerful, and built for real life. Homeowners trust it for backup, campers love it for comfort, and pros use it on the job. It charges fast, lasts long, and works when you need it most — no gas, no mess, just reliable power anywhere you go.
