EcoFlow Delta Pro is basically a 3.6Wh power station, but you can take its capacity to a huge 25kWh for emergency power to run an entire household for around 13 days. Well, for expanding its storage capacity, the brand offers you multiple options, which include the Smart Extra batteries and the EcoFlow gas generator.

When it comes to the inverter, a single Delta Pro packs up a 3600W powerful unit under the hood.

But by pairing two Delta Pros together, you can double the inverter power to a massive 7200W @ 240V. The brand offers a Smart Home panel and a Double Voltage Hub to let you enjoy the 7200W high power respectively in home circuits and off-grid applications.

By the way, its lighter variant Delta Max is a 2016Wh scalable power station with a 2400W inverter and it has got a 3400W X-Boost power. This is an option for budget-conscious users to get a highly modular power station.



Meanwhile, Bluetti EP500 and its Pro variant integrate a massive 5100Wh battery pack. You can expand it to double capacity by pairing two units of each model using the brand’s special accessory board.

That said, you can hit the 10kWh mark with two units of either EP500 or EP500 Pro.

In the process, you also get the inverter power doubled. Thus, the 2000W EP500 can deliver 4000W at 240V and the 3000W Pro variant can deliver 6000W at 240V.

Winner: EcoFlow Delta Pro

Once paired together, the EcoFlow power beast has more output and inverter power.

But to achieve the 10kWh mark, you need to connect two extra batteries to the original. By the way, taken as a unit, Delta Pro falls short in storage capacity to EP500, but it still has a bigger inverter under the hood. 

Meanwhile, two units of Bluetti EP500 or EP500 Pros can make it up to 10.2kWh.   

Expandability Features

As you see, both the EcoFlow and Bluetti are high-powered expandable power stations. They feature different ways of expanding their storage capacities and inverter power.
