MOVING THE EQUIPMENT

1. When moving the equipment by hand, wear protective gloves to prevent injuries.
2. Move the equipment with precaution as it is heavy. When two or more people are needed to assist in moving the equipment, please ensure communication and coordination between personnels to prevent being crushed or sprained.

USING TOOLS

1. Use wooden or fiberglass ladders when you need to perform live working at heights.
2. Before using a ladder, check that it is intact and confirm its load bearing capacity. Do not overload it.
3. Make sure the operator is regulated in the use of installation tools, such as ladders, electric paddles, drills, etc. Make sure the tool power cord is not tangled.
4. When installing, strictly prevent screws, nuts and spacers from falling inside the equipment and ensure that the tools (such as electric drill bit) do not fall into the gap between the installed equipment and the wall to prevent delaying the installation.

DRILLING HOLES

1. Wear goggles and protective gloves when drilling holes.
2. When drilling holes, protect the equipment from shavings or dust. After drilling, clean up any shavings or dust that have accumulated at the installation site in a timely manner, otherwise, it may block the drilled hole.

GROUNDING CONDUCTOR MONITORING

The inverter is equipped with a grounding conductor monitoring device. This grounding conductor monitoring device detects when there is no grounding conductor connected and disconnects the inverter from the utility grid if this is the case. Depending on the installation site and grid configuration, it may be advisable to disable the grounding conductor monitoring. This can be necessary, if there is no neutral conductor present and you intend to install the inverter between two line conductors.

1. Grounding conductor monitoring must be disabled after initial start-up depending on the grid configuration. Safety in accordance with IEC 62109 when the grounding conductor monitoring is deactivated. In order to guarantee safety in accordance with IEC 62109 when the grounding conductor monitoring is deactivated, you have to connect an additional grounding conductor to the inverter.
2. Connect an additional grounding conductor that has an cross-section of at least 10 mm. Ground the PE hole of GRID connector and the equipment enclosure.

Product Introduction

FUNCTION

The EcoFlow PowerOcean Hybrid Inverter enables highly efficient solar energy usage and storage to achieve your home power independence. The 3-phase inverter is integrated with backup module, offering up to 10kW output to power almost every essential appliance in case of any grid outage.

SYSTEM OVERVIEW

A diagram illustrates the system overview, showing PV Modules connecting to the Hybrid Inverter. The inverter interfaces with a Battery (EF BD-5.1-S1), Non-Controllable Loads, and a Backup Load. It also connects to the Utility Grid via a Smart Meter and a Utility Meter for billing. Optional components like a 4G module and Router are shown for connectivity. Connections include DC, AC, Ethernet, and RS485.

NETWORKING APPLICATION

This equipment applies to residential rooftop grid-tied systems. The system consists of PV strings, EF BD-5.1-S1 batteries, hybrid inverter, AC switches, and power distribution units.

SUPPORTED POWER GRID TYPES

The inverter supports the following power grid types: TN-S, TN-C, TN-C-S, and TT.

Diagrams illustrate supported power grid types: TT, TN-C, TN-S, and TN-C-S, showing typical phase (L1, L2, L3), neutral (N), and protective earth (PE/PEN) connections for each.
