Maximizing Solar System Efficiency with Lower Investment

* 6,000+ cycles until 70% degradation.

More Safety, More Reliability

Industry-leading PowerOcean LFP Battery

EcoFlow PowerOcean DC Fit is built around the advanced Power Ocean LFP battery, a parallel-connected high-voltage battery system compatible with most available solar inverters. Users can start with a single battery and expand their system at any time. With proven LFP battery chemistry and a range of active and passive safety features, EcoFlow offers unparalleled battery reliability and performance.

Key Features:

  • 5kWh per pack, expandable up to 15 kWh.
  • 6,000+ cycles.
  • IP65 weather resistance.
  • LFP Battery technology.

Enhanced Safety and Reliability

Through parallel connection, mutual interference between batteries is avoided. The failure of one battery does not affect other units. New batteries are fully compatible with already installed batteries.

Integrated BMS in each pack with cloud computing for intelligent monitoring and risk prevention, and to improve battery performance.

Fire protection module in each individual battery unit for detecting battery temperature and activating immediately if the battery temperature exceeds 170°C.

The automatic heating module activates automatically in cold weather, ensuring the battery functions optimally even at temperatures below -20°C.
