EcoFlow DELTA 3800 Gen4 Portable Power Station | 3,763Wh LFP - AllProGenerators

The EcoFlow DELTA 3800 Gen4 gives you 3,763Wh of LFP battery storage, 3,600W of continuous 120V AC output and two solar inputs. It’s a practical starting point when you want to keep a refrigerator, lights and internet going through an outage, with room to add battery capacity later. Pick the station on its own, add a cart for easier moves, or choose a kit with portable solar panels or a 2,048Wh extra battery.

Best-case uses

Refrigerator and freezer backup. Prioritize cold storage, then add small loads like lights or a router as your energy budget allows. EcoFlow’s dedicated Fridge Runtime Boost mode is designed for one compatible cooling appliance at a time.
Longer outages. Start with the built-in battery, then add compatible storage if overnight loads use more energy than you can replace during the day. More storage extends runtime while the station’s inverter remains rated at 3,600W continuous.
Cabins and campsites. Put compatible panels where they get unobstructed sun and keep the station in a dry, ventilated spot. Two separate solar inputs give you flexibility when you have two compatible arrays. Plan daily charging around actual sunlight and loads.
120V RV equipment. Use the 30A outlet for compatible RV loads. Check compressor startup demand and the combined wattage before running air conditioning, electric water heating or cooking equipment together.
Home office and garage. Back up a router and workstation, or power task lighting and compatible tools. Check what your equipment draws at startup and whether it tolerates the station’s UPS transfer time.

Battery expansion and solar charging

The base station stores 3,763Wh. A compatible 2,048Wh DELTA 3 Max Plus Smart Extra Battery brings the total to 5,811Wh. With two 4,096Wh DELTA Pro 3 Smart Extra Batteries and the required two-battery expansion adapter, the system reaches 11,955Wh of nominal storage. Choose extra batteries and accessories for your exact setup.

The U.S. 3800 has two LP60 solar inputs with separate 1,000W limits. The included panel bundles are sized for convenient portable charging. A compatible larger array can use more of the station’s solar capacity. Check the input ratings before connecting third-party panels, and budget for losses from heat, shade, angle and conversion.

Frequently asked questions

Which extra batteries work with the DELTA 3800 Gen4?

EcoFlow lists the 2,048Wh DELTA 3 Max Plus Smart Extra Battery and the 4,096Wh DELTA Pro 3 Smart Extra Battery. One Max Plus battery brings the system to 5,811Wh. EcoFlow specifies its Smart Extra Battery Expansion Adapter when connecting two extra batteries. Two DELTA Pro 3 batteries bring nominal storage to 11,955Wh.

How much solar can I connect?

The two LP60 inputs accept up to 1,000W each, with an 11–60V DC and 20A limit per port. The panel packages on this page are rated 320W, 400W or 640W. For other arrays, check the panels’ cold-weather open-circuit voltage, current, connector and polarity against each input’s limits.

Can it run a 30-amp RV or a 240V appliance?

The U.S. model supplies 120V AC, including a 30A RV-style outlet. It can power compatible 120V RV loads within its 3,600W total rating and the individual outlet limits. Use a 120V load plan. A 240V appliance requires a compatible 240V power source.

How long will it run my refrigerator?

Start with the refrigerator’s measured daily energy use and account for door openings, room temperature, other loads and inverter losses. EcoFlow’s Fridge Runtime Boost is designed for one compatible AC compressor-based cooling appliance at a time. Follow EcoFlow’s instructions for that mode.

Can I use it for home-office backup?

Yes. The under-10 ms transfer rating can be useful for compatible routers, monitors and other electronics. Test your equipment during a controlled outage before relying on it. EcoFlow does not list USB HID communication for this UPS function.
