EcoFlow Smart Generator 4000 (Dual Fuel)

Description

Industry’s Fastest 3200W DC Fast Charging System

Higher efficiency, more reliable when connected with EcoFlow DELTA Pro 3

Unlock unmatched power and reliability with the EcoFlow Smart Generator 4000 (Dual Fuel) and EcoFlow DELTA Pro 3 hybrid setup. Featuring industry-leading 3200W DC fast charging and up to 40% improved efficiency, they excel in various scenarios, from backup power to on-the-go charging.

More Energy-Saving & Efficient

EcoFlow Smart Generator (Dual Fuel) 4000 not only offers significant fuel savings but also generates fewer emissions. Compared to traditional fuel generators, it can save 40% of fuel when fully charging EcoFlow DELTA Pro 3. This means that with the same 1 gallon of fuel, this smart generator provides 1kWh more power.

Power Backup Made Smart and Simple

With four intelligent self-starting backup modes (when paired with EcoFlow DELTA Pro 3), power backup has never been easier.

Customizable start/stop

At night, once the power consumption reaches a certain level, the smart generator will automatically start to replenish power, eliminating the need to get up in the middle of the night to reset it.

Night-care mode

Monitor the remaining power of the EcoFlow DELTA Pro 3 energy storage in real-time, predict future power consumption and measure the power generation from PV, and auto-recharge it in time to ensure a peaceful night's sleep and rest for your family and neighbors, avoiding noise during charging at night or during peak power consumption periods.

PV-priority mode

Recharge the EcoFlow DELTA Pro 3 with PV panels, automatically prioritizing PV charging for savings and environmental benefits while minimizing noise from continuous generator operation. Need more power quickly as an outage approaches? One tap in the EcoFlow app switches back to PV and Smart Generator charging combo for swift reinforcement.

Smart reverse charging

It provides a reverse power supply to the generator battery through EcoFlow DELTA Pro 3 to wake up the generator and start charging it at the same time. Also, to prevent the Smart Generator battery failure caused by long-term storage or extremely low temperatures, it protects household electricity during severe weather scenarios.

Dual Fuel for Double Peace of Mind

Gasoline Power

The smart engine produces 8kWh in single gasoline tank, you could power your home appliances for 8-hours at 25% load.

Propane Power

Simply plug in a 20lb propone tank and allow you access to a 24kWh power, secured and keep your family a whole day of cozy life in a outage.

Control from Anywhere with Just One Tap

Great tub, easy setup

It’s amazing that this is a portable hot tub. It was easy to setup and looks like a permanent hot tub! It took about 2 days to heat to 104. We live in a place that snows so we added extra insulation to the panels and extra ground cover.

The jets are not super strong so I would have preferred getting the Tribeca which is less expensive and comes without jets. It does have bubbles.

But overall a great product, first of its kind I believe.

Outdoor Sauna CL4G Cube

We pre ordered this sauna. It’s all put together with the help of a contractor. It took 2 guys 2 full days. We are very pleased with the sauna all together. It’s clearly top of the line. The sauna fits 2. Maybe 3 if you want to squeeze. The sauna fits well in our backyard. It adds a sense of tranquility to our favorite space. Off grid was extremely easy to work with. It was clear they put the customer first!

Love the machine!

I absolutely love the machine. I use it everyday. I was disappointed to see some paint scratches on it when it arrived. However, after some contact with their Customer Service department we were able to sort it out. I highly recommend getting a freeze dryer!

Ideal Power station AC180P

I was in the market for a power station that has enough power and capacity to power my fridge and some essential appliances at my house. I come upon this power station from OffGrid living Solutions and I have been using it since. It has enough power for a longer period of time and has multiple ways to charge (AC/Solar Panels). This station is perfect in size and comes at an affordable price. Thank you OffGrid Living team and Bluetti ....

Such a quality sauna heater

My wife and I love this heater for our sauna. We love the automatic feature of the heater where it turns off once the optimal heat level is reached. Sturdy and durable product, especially for anyone looking to install one on their saunas

Anker Solix F2000 with Solar Panels

This unit is perfect for power outages! We were looking for a unit that can power our essentials during outages like TV, fridge, microwave, lights, and our wifi. This unit can also act as a UPS so nothin shuts off when the power goes down. I like to connect my solar panels to the station when it looks like the outage will be extended. GET THIS STATION! YOU WILL NOT BE DISAPPOINTED!

Anker SOLIX F2000 (PowerHouse 767) Portable Power Station Solar Generator + 100W Solar Panel
Great Solar Generator!

System performs well in powering things and amazing hardware build quality. One issue I have with AC200Max is that I cannot control it remotely via the internet so when it shuts down due to depletion of battery and turns on again after solar hits the panels, I have no way of turning the AC output on remotely. The other thing is that it lacks portable wheels, carrying this thing is a chore. Other than that, this is a pretty good unit and for those who don't need to have the remote control, this could be your solar generator. OLS team was good and respondant on all of my questions. Overall, this solar generator offers excellent power output and capacity to run nearly anytthing you plug into it.

Great product and keeps you cool during trips

Wave 2 is a quiet portable air conditioner, even when you put in on Max mode. I purchase this is for my van for during the hot days during camping. Love that I can carry this to around with ease. I plan to use the heating feature once it gets colder. I'm happy with my purchase and can't wait to see how it functions on the heating side.

Works great!

The AC200 Max and B230 work Great! So much that I added another B230 on the next order. This set up will be used for my farm in the summer and as a emergency back up in my home when it gets cold. Great product! Thx Bluetti and OffGrid Living Solutions

A Game-Changing System

I recently invested in the EcoFlow Delta Pro and I am beyond impressed with its performance.

Setting up the Delta Pro was a breeze. The user-friendly interface and informative display made it easy to monitor power consumption and remaining battery life. Plus, the variety of charging options means I can harness energy from solar panels, car chargers, and regular outlets, making it perfect for both everyday use and outdoor adventures. One of the standout features for me is its portability. Despite its robust power capacity, the Delta Pro is surprisingly lightweight and compact, allowing me to take it on camping trips, picnics, and even to power my work tools at remote job sites.

The customer service I received from EcoFlow was exceptional. They promptly answered my questions and provided helpful insights into maximizing the Delta Pro's capabilities. Overall, I would highly recommend this portable power station.

Great Customer Service Team. The first batch of seeds are already growing. Looking forward to fresh greens. The only negative about this garden is that it was difficult to set up as the manual instructions were unclear
