• The operating temperature of the battery ranges from –20°C to +50°C. If the battery is installed in a cold environment, the built-in thermal control system starts to heat the battery to achieve better performance. The heating process consumes rechargeable power, which reduces the system’s energy efficiency for a short time in cold weather.

• If the battery is stored in a cold environment (for example, 0°C) before installation, the battery needs some time (< 30 minutes) to heat up before
  it can be charged. You are advised to place the battery in a warm place before installation.

• When the ambient temperature of the battery is higher than +45°C or lower than –10°C, the battery charge and discharge power will be derated.

EQUIPMENT AND PERSONNEL SAFETY REQUIREMENTS
MOVING THE EQUIPMENT

2. When moving the batteries, both hands should hold the handle at the top of the battery firmly, do not put your hands at the bottom of the battery when the batteries are being stacked and installed, otherwise, it may crush your hands.
3. Move the batteries with precaution as the battery modules are heavy. When two or more people are needed to assist in moving the batteries, ensure communication and coordination between personnel to prevent being crushed or sprained.

USING TOOLS

1. Use wooden or fibreglass ladders when you need to perform live work 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 on time, otherwise, it may block the drilled hole.

FUNCTION

This battery system consists of a battery junction box, battery expansion modules and a battery base. It can store and release electric energy based on the requirements of the inverter management system. The input and output ports of the EF BD-5.1-S1 battery are high-voltage direct current (HVDC) ports.

• Battery charge: The junction box connects to the battery terminals (BAT+ and BAT–) of the inverter. Under the control of the inverter, the system charges the batteries and stores excessive PV energy in batteries.
• Battery discharge: When the PV energy is insufficient to supply power to the loads, the system controls the batteries to supply power to the loads. The battery energy is output to the loads through the inverter.

BATTERY CAPACITY DESCRIPTION
The battery supports power and capacity expansion. Up to three junction boxes can be connected in parallel. One junction box supports a maximum of three battery expansion modules.

NETWORKING APPLICATION
EcoFlow PowerOcean LFP Battery is a parallel connected high voltage battery system, compatible with our 3-phase hybrid inverter.

FEATURES

MULTI-SCENARIO AND MULTI-WORKING MODE

• Supports multiple working modes such as grid-tied, power backup scenario, and self-consumption mode.
• Allows users to query the total discharge capacity in the product life cycle in real-time.

INTELLIGENT AND SIMPLE OPERATION
Works with the inverter, supports plug-and-play, and integrates the mobile phone app.

EASY INSTALLATION AND REPLACEMENT

• Standard battery DC terminals are used for system connection.
• A modular design is adopted for batteries, which are stacked and connected without external cables.
• A modular design is adopted for battery junction box, which is designed for easy connection to the inverter.
• Sleek Design saves installation space.

FLEXIBLE SCALABILITY

• The battery system supports power expansion, battery capacity expansion, and hybrid use of old and new batteries.
• The battery system supports the isolation of failed battery modules to ensure that the energy storage system can still operate normally

INTELLIGENT OPERATION AND MAINTENANCE

• The factory defaults meet the requirements of target markets and the battery can be started by pressing only one button and supports black startup.
• The LED indicator shows the status. You can also use the EcoFlow app to perform local and remote operations and manage the battery anytime and anywhere.

SAFE AND EFFICIENT

• The BMS module is embedded within every battery pack, achieving a compact design with no extra power module on top of the batteries.
• Active aerosol fire protection module in every battery pack to secure maximum safety

System Modes

SELF-POWERED MODE

• This mode applies to areas where the electricity price is high or areas where the feed-in tariff subsidy is low or unavailable.
• Excess PV energy is stored in batteries. When PV power is insufficient or no PV power is generated at night, batteries discharge to supply power to the loads, improving the self-consumption rate of the PV system and the self-sufficiency rate of residential energy, and reducing electricity costs.
• In this mode, by default, the charge cutoff capacity is 100% and the discharge cutoff capacity is 5% for EcoFlow EF BD-5.1-S1 LFP batteries.

BATTERY STORAGE AND RECHARGE
BATTERY STORAGE REQUIREMENTS

• Place batteries according to the signs on the packing case during storage. Do not put batteries upside down or sidelong.
• Stack battery packing cases by complying with the stacking requirements on the external package.
• Handle batteries with caution to avoid damage.
• The storage environment requirements are as follows:
• Ambient temperature: -10–55°C; recommended storage temperature: 20–30°C
• Relative humidity: 0% to 100%
• Place batteries in a dry and clean place with good ventilation.
• Place batteries in a place that is away from corrosive organic solvents and gases.
• Keep batteries away from direct sunlight, heat source, fire source and water source.
• The batteries in storage must be disconnected from external devices. The indicators on the battery junction box should be off.
• If the battery is not used for a long period of time, it is recommended to be stored intact in a semi-charged state (60% SOC). The battery is recommended to be discharged to 30% and then recharged to 60% every three months.
• If the power level of the battery is lower than 1% after use, recharge it to 60% before storage. If the battery has been idle for a long time when the power is seriously insufficient, it will cause irreversible damage to the cells and shorten the service life of the battery.
• If the battery has been idle for a long time and the power level is severely low, it will enter a deep sleep protection mode. In such a case, recharge the battery before using it again.
• When solar irradiance declines and the PV string current drops to below 0.5 A, and the battery SOC is excessively low, the system will automatically switch to Grid power.

REPLACING A FUSE
The Battery junction box has a built-in DC 1500 V/20A replaceable fuse. Under normal operating conditions, there is no risk of fuse blowing. When an external short circuit occurs and the battery management system is not protected in time, the fuse will blow immediately to protect the battery. When a short circuit occurs and the battery cannot be charged or discharged, the fuse must be replaced. Replacement procedure is as follows:

NOTICE

• Please use fuses with local certification standards

PROCEDURE

1. Power off the system. For details, see chapter: System Power-Off.
   WARNING

   • After the system is powered off, the remaining electricity and heat still exist in the chassis, which may cause electric shocks or burns. Therefore, you need to wear protective gloves and perform operations 5 minutes after the system is powered off.
   • Only qualified professionals are allowed to replace a fuse.

2. Loosen the screws on the fuse shell.

3. Lift the fuse box opening, remove the fuse, insert a new fuse of the same specification as the old one into the slot, and close the fuse box.

4. Lock the fuse shell with screws.

FUSE SPECIFICATION
