One of the most impressive features of the EcoFlow DELTA Pro 3 is its expandability. If you want to be fully prepared for severe power outages, you can chain two Delta Pro 3 units together with a 50-amp hub or Smart Home Panel 2 to get an output of 8 kW and a capacity of 24 kW hours. And if you need even more power, you can chain three Delta Pro 3 units together on a Smart Home Panel 2 to get an output of 12 kW and a massive capacity of 36 kW hours. And if that’s still not enough, you can achieve a maximum capacity of 48 kW hours by combining a Delta Pro 3 unit with a dual-fuel Smart Generator 4,000 setup – enough to power your entire house for days.

But the EcoFlow DELTA Pro 3 is not just about power. Its X-Fusion technology allows it to bypass the grid’s output limitations and accommodate high-power appliances with ease. Plus, with its quiet operation at just 30 decibels, you won’t even notice it’s running. This is achieved through its innovative internal air structure, which separates high and low-temperature components and uses dual air duct partitioning for efficient and quiet cooling.

When it comes to charging, the DELTA Pro 3 offers 7 unique ways to recharge, including AC wall charging, dual PV charging, a smart home panel 2, and even EV charging. With the right combination, you can input up to 7,000 watts and charge a single Delta Pro 3 unit from 0 to 80% in just 50 minutes. And with its portability and compact size, you can easily take the Delta Pro 3 with you wherever you go.

One of the standout features of the DELTA Pro 3 is its professional bypass mode, which allows it to act as an amplifier when plugged into a 120-volt grid. This means it can bypass the grid’s output power limitation of 1,800 watts by supplementing grid electricity in parallel with the inverter, achieving a maximum output of up to 4,000 watts. This feature comes in handy when you need to run high-power appliances continuously, such as an air compressor or electric drill.
