Differences Between Bluetti AC300 vs EcoFlow Delta Pro
Below is a summary of the specifications:
Battery Capacity and Expandability
The Bluetti AC300 is unique in that it is a modular power station. The main unit does not include a built-in battery; instead, it must be paired with at least one B300 expansion pack, which provides 3,072 Wh. With up to four packs, the system reaches 12,288 Wh, making it highly adaptable depending on user needs and budget.
The EcoFlow Delta Pro offers 3,600 Wh out of the box, which is slightly higher than the Bluetti’s minimum setup. Its expandability, however, is far greater, supporting up to 25,000 Wh when linked with additional batteries and EcoFlow’s Smart Home Panel, enabling whole-home backup capabilities.
Winner: EcoFlow Delta Pro, thanks to larger maximum expandability and higher base capacity.
Power Output and Device Compatibility
The AC300 delivers 3,000 W of continuous AC power with a surge capacity of 6,000 W. This is sufficient for running refrigerators, power tools, and other heavy-duty appliances. It supports both 120V and 240V split-phase setups when paired with two units, making it flexible for home integration.
The Delta Pro provides 3,600 W continuous output and 7,200 W surge, giving it a stronger upper limit. It also supports 240V split-phase operation, making it suitable for large appliances like dryers, water heaters, and even EV charging. With multiple output types, including dual 100 W USB-C ports, it also handles modern electronics effortlessly.
Winner: EcoFlow Delta Pro, due to higher rated and surge output plus versatile port setup.
Charging Speeds and Solar Integration
The Bluetti AC300 shines in solar input. With its 2,400 W dual MPPT capability, it leads the industry in renewable energy efficiency for off-grid setups. This makes it an excellent choice for users heavily reliant on solar energy.
The EcoFlow Delta Pro accepts up to 1,600 W of solar input, which is strong but not as powerful as the Bluetti. However, EcoFlow’s X-Stream charging technology enables the Delta Pro to achieve multi-source recharging, combining AC, solar, and even EV charging stations, resulting in incredibly fast recharge times.
Winner: Bluetti AC300 for raw solar input capacity, though Delta Pro excels in flexible charging options.
Design, Portability, and Build Quality
The Bluetti AC300 weighs only 47.6 lbs for the main unit, but because it requires external batteries, the total system weight quickly adds up. Its modular design makes it easier to carry individual pieces instead of one massive unit.
The EcoFlow Delta Pro is a single integrated system weighing 99 lbs. To aid portability, it includes wheels and a telescoping handle, similar to rolling luggage. While heavier, this all-in-one solution may be more convenient for users who don’t want to manage multiple modules.
Winner: Tie – Bluetti AC300 for modular flexibility, EcoFlow Delta Pro for wheeled portability.
Smart Features and App Integration
Both units come with Wi-Fi and Bluetooth-enabled apps, allowing real-time monitoring, firmware updates, and remote management.
The Bluetti app offers detailed solar tracking and flexible charge/discharge scheduling. The EcoFlow app goes a step further by providing integration with the Smart Home Panel, making it easier to manage home circuits and energy use.
Winner: EcoFlow Delta Pro, thanks to deeper home integration and more advanced ecosystem features.
