EcoFlow Power Ocean 5 kWh Battery — Reliable Modular Solution for Energy Independence
EcoFlow Power Ocean 5 kWh — a high-voltage LFP battery from the EcoFlow brand, designed for creating hybrid 3-phase power supply systems in homes, commercial facilities, or microgrids. A single unit has a nominal capacity of 5 kWh and serves as a base unit for scaling the system up to 45 kWh, providing flexibility in design and operation.
Features and Benefits
- High operating voltage — up to 800 V thanks to a built-in DC-DC converter in each module, which allows independent voltage conversion between 48 V and 800 V.
- Modular architecture — the initial unit allows starting a 3-phase system, and connecting units in parallel ensures capacity expansion up to 45 kWh.
- Enhanced safety — each module operates autonomously with an integrated BMS and converter, so a malfunction in one unit does not affect other system elements.
- Automotive-grade BMS with TI chip — ensures precise battery status control and longer operation.
- Cloud BMS support — remote monitoring, analytics, and intelligent risk management via cloud services.
- Active aerosol fire suppression module with thermal sensor — activates when the temperature exceeds 270 °C for increased safety.
- Protection and operation in harsh climatic conditions — automatic heating for operation in freezing temperatures and an IP65-rated enclosure.
- Compact and thoughtful design — a durable matte metal casing approximately 180 mm thick allows the unit to be installed in a basement or garage; a hinged flap on the inverter and control box is provided for neat cable concealment.
