Safety Precautions

avoided, will result in death or serious injury.
WARNING| Indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury.
CAUTION| Indicates a hazard with a low level of risk which, if not avoided, could result in minor or moderate injury.
NOTICE| Indicates a potentially hazardous situation which, if not avoided, could result in equipment damage, data loss, performance deterioration, or unanticipated results.
NOTICE is used to address practices not related to personal injury.

DANGER

• Do not work with power on during installation or maintenance.
• Personnel who plan to install, maintain, or perform electrical operations on the equipment must receive thorough training, and be familiar with all necessary safety precautions and instructions.
• Personnel who plan to perform special operations should have the necessary local or national qualifications for tasks such as high-voltage operations, working at heights, and so on.
• Wear suitable personal protective equipment (PPE) for all professional or skilled work on the equipment.
• WARNING
  • When the photovoltaic (PV) array is exposed to light, it supplies direct current voltage to the power conversion equipment (PCE).
  • Do not touch the exposed electrical cable with bare hands.

Installation Environment

WARNING

• The installation and use environment must meet relevant international, national, and local standards for lithium batteries, and be in accordance with the local laws and regulations.
• NOTICE
  •  When installing the equipment in a garage, keep it away from the drive way.
  • The mounting structure where the equipment is installed must be fire resistant. Do not install the equipment on flammable building materials.
  • Ensure that the installation surface is solid enough to bear the weight of the equipment.

Installation Space

• WARNING
  • Reserve enough clearance around equipment to ensure sufficient space for installation and heat dissipation.
• NOTICE
  • Reserve enough space on both sides of the equipment to facilitate the locking operation of the screws.

System Installation

• DANGER
  • When drilling screw holes, avoid the water pipes and power cables buried in the wall and under the floor.
• CAUTION
  • When moving heavy equipment, assign enough personnel (two or more).
  • When moving the battery pack, hold the handles on top of it.
• NOTICE
  • Install the provided adjustable feet to level the battery base if needed.

DANGER
Grounding terminals should be fully connected.

Electrical Connection

• DANGER
  • Keep the protective cap of the unused terminal on the converter. Otherwise, the IP rating of the converter will be affected.
• CAUTION
  • Only qualified persons can perform the following operations.
• NOTICE
  • Use cables that meet local regulations and the recommended specifications.

EcoFlow PowerOcean PV Storage Converter

BATTERY SWITCH

• ON: EcoFlow PowerOcean DC Fit stores the excess electricity generated by solar panels, and then supplies it to the home load when solar power is insufficient.
• OFF-BYPASS: EcoFlow PowerOcean DC Fit does not function as a power storage or backup unit. The electricity produced by solar panels goes to a solar inverter through the converter.

Cable Requirements

1. PV input cable
   4 mm² – 6 mm² conductor

2. Inverter connection cable
   4 mm² – 6 mm² conductor

3. Smart meter communication cable
   Twisted-pair cable 2*0.5 mm²

4. Ethernet cable
   Cat 5e or higher shielded network cable

5. PE cable
   4 mm² copper conductor

System  Preview

Connecting to PV System

DANGER

• Power off the solar inverter from all voltage sources (both DC and AC sides) and disconnect it from the grid.
• If the PV string has no DC breaker or isolator to shut off DC input, do not cut all PV cables at once.
• Check if all equipment, components, cables, and terminals are in good condition.
• Do not hold the leads from “PV+” and “PV-” on the solar panels at the same time. The solar panels will generate lethal high voltage when exposed to sunlight.
• All terminals must be connected in the correct polarity to prevent damage to the system or risk of electric shock. Always connect positive (+) to positive (+) and negative (-) to negative (-).
• The DC input voltage and the short-circuit current of each PV string input must not exceed Max Input Voltage and Isc PV (Absolute Maximum).
• The impedance between the positive/negative terminals of the PV strings and earth should be larger than 1MΩ. Do not connect the PV strings to earthing or grounding conductor.

WARNING
Use the solar connectors provided in the package. Do not cross-mating solar connectors of different manufacturers.

NOTICE

• To prevent lightning damage to the converter, add a surge protection switch at the PV junction box (if applicable).
• Avoid connecting any solar panels with a risk of leakage current to the converter.
• Avoid mixing solar panels that have different electrical characteristics to one PV string input. Also, avoid connecting solar panels with different orientations or angles.
• After the solar connectors have snapped into place, always check if the connection is secure.

A Check the BATTERY SWITCH status on the converter.

B De-energize all electrical equipment. All switches connected to the existing solar power system should be OFF status.

C Cut existing solar cables.

D Prepare solar connectors for the PV strings and the inverter.

Do not cross-mate solar connectors of different manufacturers.

E Check the polarities of the connection cables.

NOTICE

• If the multimeter displays a negative value, the polarities of the leads are reversed. Correct them and try again.
• If the multimeter displays a voltage exceeding 1000V, remove some solar panels.

F Connect to the converter.

NOTICE
To remove or remake the solar connectors, use the provided solar connector spanner to remove them.

For an inverter that only supports single PV string input, adjust the connection using the EcoFlow Y-branch Solar Connector

For an inverter that supports multiple PV strings (≥ 2 strings) in one input, avoid paralleling the EcoFlow PowerOcean DC Fit with a PV string to prevent potential damage to solar panels.

Connecting Smart Meter

NOTICE
Use the smart meter provided in the package.

Wiring diagram (three-phase)

NOTICE
For a three-phase house wiring, always adhere to the three-phase wiring diagram when installing the smart meter, irrespective of whether a single- phase inverter is in use.

Wiring diagram (single-phase)

Connecting to the Internet

NOTICE
Use Cat 5e or higher rating shielded network cable.

Method 1 : Via a Wired Network

Both ends of the network cable use the T568B wiring standard (straight-through cable).

Test network cable connection. If the LEDs of the two RJ45 ports light up in sequence, it indicates that the network cable is correctly wired and should be fully operational.

Method 2: Via a Wireless Network
Adjust the Wi-Fi antenna, then refer to System Commissioning section in this guide to connect the device to a wireless network.
