This EcoFlow Delta Pro setup guide covers first-day charging and settings, what the Smart Home Panel does, and every accessory from solar panels to the Smart Generator, ranked by value.
Getting an EcoFlow Delta Pro running is simple: charge it, pair it with the app, plug things in. Getting the most out of it takes a little more thought, because the Delta Pro is really a platform. Extra batteries, solar panels, the Smart Home Panel and the Smart Generator each turn it into a different tool, from a rolling outage box to a hands-off home battery. This guide walks through first-day setup, the settings worth changing, and every accessory in the ecosystem with an honest view of which ones earn their price.
The Delta Pro ships partially charged. Plug the included AC cable into the input on the back and into any standard wall outlet. At its default 1,800W rate it fills from empty in under two hours. If you are on a shared 15A circuit or want to be gentle on the cells, open the app and lower the AC charging speed; it will take longer but pull less current. You can also charge from solar, an EV station or the Smart Generator on day one, but the wall is simplest.
Download the EcoFlow app, create an account, and add the Delta Pro over Bluetooth, then connect it to your home Wi-Fi so you can monitor it when you are not standing next to it. The app shows input and output watts, battery percentage, time to full or empty, and lets you toggle each output group. Check for a firmware update while you are there.
If you bought a Smart Extra Battery, power everything off first. The battery cable connects to the port on the side of the Delta Pro and the matching port on the battery. Power the Delta Pro on and the app will show the combined capacity, 7.2kWh with one battery or 10.8kWh with two. The system charges and discharges all connected packs as one; you do not manage them separately.
Turn on the AC output with the button on the front and plug in a load. Watch the output watts in the app to learn what your appliances actually draw; a refrigerator's compressor cycle is instructive the first time you see it. Test the USB-C ports with a laptop and the 12V ports with anything you plan to run from them.

The EcoFlow Smart Home Panel is the accessory that changes what a Delta Pro is. Installed by an electrician between your utility meter and your main breaker panel, it connects up to ten household circuits to one or two Delta Pro units. When the grid drops, it switches those circuits to battery in under 20 milliseconds, faster than most electronics notice, and switches back when power returns. Two Delta Pros through the panel deliver 7,200W and 240V, enough for a well pump or dryer, and the system supports up to 25kWh of storage with extra batteries.
The panel also does things no extension cord can. In the app you assign priority to each circuit, so as the battery drains it sheds the least important loads first. You can schedule the Delta Pro to charge overnight on cheap time-of-use rates and discharge during expensive peak hours, which in some utility territories pays for the system over time. And you get per-circuit energy monitoring for the whole house.
Is it worth $1,399 plus installation? If you want backup that happens without anyone rolling a unit to a doorway and running cords, yes. If you have medical equipment, a well, a sump pump or a home office that cannot tolerate a gap, yes. If your outages are rare and you are happy to plug in a fridge and a lamp by hand, the money is better spent on a second battery or more solar. The panel requires a licensed electrician and a permit in most jurisdictions; our team can point you to a qualified installer.
The best first upgrade for almost everyone. Solar does not add storage; it adds generation, and 400W of panels covers a refrigerator's daily draw. The Delta Pro accepts up to 1,600W at 11 to 150V. Wild Oak Trail stocks the EcoFlow 400W portable panel ($699), the 220W bifacial ($399) and the 400W rigid two-pack ($999) for roof mounting. Our solar and battery guide covers sizing and series-parallel wiring.
Each Smart Extra Battery adds 3,600Wh for $1,199 and the Delta Pro takes two. Buy one when you need more than two days of fridge and freezer, or when you want to run heating or cooling for more than a couple of hours. The Delta Pro with one battery is $2,959 as a bundle.
Covered above. The upgrade for hands-off, whole-circuit backup.
The EcoFlow Smart Generator is a dual-fuel inverter generator that connects directly to the Delta Pro and charges it at 1,800W on gasoline or 1,600W on propane, filling it in about 2.7 hours. Its purpose is weather-proof runtime: when a storm blocks the sun for days, the Delta Pro tells the generator to start when the battery runs low and stop when it is full, so the generator runs only a couple of hours a day instead of continuously.
A 20 lb propane cylinder yields about 20kWh. It is $1,299, or $4,399 bundled with the Delta Pro, and uses the $69 Delta Pro to Smart Generator adapter. The newer Smart Generator 4000 ($1,259) delivers 3,200W DC and is designed for the DELTA Pro 3 and Delta Pro Ultra; check the product page for Delta Pro compatibility before buying.
EcoFlow's Wave 2 is a portable AC and heater that runs directly from the Delta Pro. The pair is sold at Wild Oak Trail for $4,399 and is the cleanest way to cool a bedroom or RV during an outage. Expect four to six hours of cooling per Delta Pro charge on high, longer in eco mode.
A spare AC charging cable ($22) and car charging cable ($22) are worth keeping in the vehicle. MC4 to XT150 adapters are needed for third-party panels. A heavy-duty power strip solves the "not enough AC outlets" problem during an outage.
If you are building out a van, RV or off-grid cabin and want a fixed installation rather than a portable unit, EcoFlow's Power Kits in 2 to 15kWh sizes are a separate product line designed for that job. They are not Delta Pro accessories, but they are the answer when someone asks how to make the Delta Pro "permanent."

At 99 lbs the Delta Pro rolls, it does not carry. The built-in wheels and telescoping handle handle garage floors, driveways and paved paths well. For stairs, truck beds and gravel, plan on two people or a ramp. Keep extra batteries as separate 84 lb pieces rather than trying to move a stacked system. In a van or RV, strap the unit down in a bay with airflow on both sides; the fans need clearance.
For storage, keep it between roughly 50 and 90 percent charge, in a space that stays between about 32°F and 100°F, and top it up every three to six months. EcoFlow lists a one-year shelf life after a full charge. Never store it fully discharged. A garage or basement is ideal; an unheated shed in a northern winter or a closed vehicle in summer is not.

Charge it from a wall outlet, which takes under two hours at 1,800W. Pair it with the EcoFlow app over Bluetooth and connect it to Wi-Fi. If you have a Smart Extra Battery, connect it with the power off. Turn on the AC output and plug in your loads. Set a charge ceiling and turn on X-Boost in the app.
It connects up to ten household circuits to one or two Delta Pro units and switches them to battery in under 20 milliseconds when the grid drops. Two Delta Pros through the panel deliver 7,200W and 240V with up to 25kWh of storage. It also lets you prioritize circuits, schedule charging on off-peak rates and monitor energy use per circuit. It requires installation by a licensed electrician.
No. You can plug appliances directly into the Delta Pro during an outage, or use EPS mode to pass grid power through and switch to battery automatically for whatever is plugged into it. The panel is for automatic, whole-circuit backup without running cords.
Solar panels. A single 400W panel covers a refrigerator's daily draw and turns a one-day backup into an indefinite one in decent weather. The Smart Extra Battery is the next most useful, followed by the Smart Home Panel for automatic switchover.
It connects directly through an adapter and charges the Delta Pro at up to 1,800W, filling it in about 2.7 hours. The Delta Pro can start the generator automatically when the battery runs low and stop it when full, so the generator runs only a couple of hours a day during a long outage instead of continuously.
You can strap it down and wire loads to it, but for a truly fixed installation EcoFlow's Power Kits in 2 to 15kWh sizes are designed for that purpose. The Delta Pro's strength is that it remains portable.
