Single-Phase Converter for EcoFlow PowerOcean DC-Fit 5 kW Battery

The PowerOcean DC-Fit is a converter that allows you to add battery storage to an existing solar installation without replacing the inverter. It is installed on the solar panel side and intelligently manages energy to charge and discharge the battery, while maintaining the normal operation of your current inverter.

What it solves

• Upgrade your system with a battery without any AC-side work or inverter replacement.
• Increased self-consumption: store excess solar energy during the day and use it at night or during peak hours.
• Wide compatibility: designed to work with a large variety of inverters on the market.

How it works

The converter connects between the panels and the inverter. When there is surplus solar production, it directs part of that energy to the battery; when needed, it discharges the battery back to the inverter to cover consumption. It features a direct pass-through (bypass) that allows the inverter to continue receiving power from the panels even when the battery is full or the converter is in standby mode.

Key features

• Panel-side charging power: up to 5 kW.
• Direct pass-through: up to 15 kW per panel string to avoid limiting inverter production.
• Operating voltage range on the panel side: approximately 150–800 V.
• Admissible short-circuit current per string: up to around 21 A.
• Protection rating: IP65, suitable for indoor or protected outdoor installation.
• Cooling: natural convection, silent operation.
• Connectivity: Ethernet, Wi-Fi, and Bluetooth for configuration and monitoring via the EcoFlow app and web portal.
• Operating temperature: approx. −20 °C to 50 °C; altitude up to 3,000 m.
• Rail mounting and compact design for easy professional installation.

Batteries and expansion

• Compatible with EcoFlow PowerOcean DC-Fit high-voltage batteries (LFP chemistry), with modular configuration.
• Typical system capacities: around 5.1 / 10.2 / 15.3 kWh, depending on the number of modules installed.
• The system output power can reach up to 5 kW with multiple batteries installed.

Installation advantages

• True retrofit: leverage your existing inverter and structure, reducing costs and installation time.
• Clean integration: usually does not require modifications to AC distribution panels.
• Smart management: charge/discharge modes and real-time monitoring via the app.
