OCEE5K Key Specifications

5.12kWh 51.2V 100Ah Low-Voltage LFP Battery

The OCEE5K combines a nominal voltage of 51.2V with 100Ah capacity to provide 5.12kWh of nominal stored energy in one floor-standing battery unit.

The 51.2V battery platform is intended for compatible 48V-class low-voltage hybrid and off-grid inverter systems.

Actual usable energy depends on the battery operating window, inverter settings, battery state of charge, temperature and final system configuration.

Ultra-Slim 140mm Floor-Standing Design

One of the main design characteristics of the OCEE5K is its 140mm enclosure depth. Overall dimensions are 400 × 140 × 660mm.

The slim vertical format reduces the floor depth required for battery installation and can be useful in utility rooms, equipment rooms and other indoor locations where available floor space is limited.

The battery has a net weight of approximately 44.2kg. Suitable handling methods and installation procedures should be used when positioning the unit.

50A Continuous Charging

The OCEE5K supports a maximum continuous charging current of 50A.

The inverter or battery charger should be configured so that charging voltage and charging current remain within the battery's published limits.

Battery charging performance can also vary with temperature and battery state of charge, so the complete battery and inverter configuration should be reviewed during system design.

100A Continuous Discharge Current

Maximum continuous discharge current is specified at 100A.

The actual continuous AC power available to connected loads depends on battery voltage, inverter efficiency, inverter rating and system operating conditions.

DC cables, terminals, breakers and protection devices should be selected according to the expected battery current and applicable electrical installation requirements.

150A Pulse Discharge for One Second

The battery provides a published maximum pulse discharge current of 150A for one second.

Short-duration current capability can assist compatible systems during temporary surge demand. Actual motor or compressor starting capability also depends on the inverter surge rating, battery state of charge, cabling and connected equipment.

Published 8000-Cycle LFP Battery Life

The current OCEE5K product datasheet specifies Grade-A LFP cells with a published cycle life of 8000 cycles.

Battery service life depends on depth of discharge, charge and discharge rate, temperature, state-of-charge operating window and the conditions used for cycle-life testing.

Where cycle-life assumptions are required for project calculations, the applicable test conditions and end-of-life capacity criterion should be confirmed before final system design.

Built-In Battery Management System

The OCEE5K incorporates a built-in BMS for battery management and protection.

The published protection functions include overcharge protection, over-discharge protection, over-current protection, short-circuit protection and over-temperature protection.

CAN and RS485 Inverter Communication

CAN and RS485 communication interfaces are provided for communication between the battery BMS and compatible energy storage inverters.

Physical CAN or RS485 connectivity alone does not guarantee inverter compatibility. Battery voltage, charge and discharge current limits, communication protocol and inverter firmware must all be considered.

Installers and distributors should provide the exact inverter model before ordering so that battery compatibility can be checked.

IP21 Indoor Energy Storage Battery

The OCEE5K has an IP21 ingress protection rating and is intended primarily for protected indoor installation.

Suitable installation locations may include utility rooms, equipment rooms, protected garages and other indoor areas that meet the product's environmental and electrical installation requirements.

The battery should not be treated as an IP65 outdoor battery. Where outdoor installation is required, an appropriately rated battery or approved protective enclosure should be selected.

Environmental Operating Conditions

The published working-temperature range is -10°C to +50°C, while storage temperature is specified at 0°C to +30°C.

Relative humidity is specified from 0% to 95% non-condensing, and the published maximum operating altitude is 1500m.

Battery charging and discharging capability may be affected by environmental temperature, so site conditions should be considered when selecting the installation location.

Parallel Expansion for Larger Battery Capacity

The current product datasheet specifies that parallel battery expansion is supported.

This allows multiple compatible OCEE5K units to be considered where greater energy storage capacity is required.

The maximum permitted number of parallel batteries is not specified in the current datasheet. Final battery quantity, communication topology, DC protection and inverter limitations should therefore be confirmed before system design.

Optional LCD Display

An LCD display is available as an optional configuration according to the current product specification.

Buyers requiring a local battery display should confirm the required configuration when requesting a quotation.

Typical Solar Energy Storage System Integration

The OCEE5K can be combined with compatible photovoltaic modules, a hybrid or off-grid inverter and electrical loads to create a battery-based solar energy storage system.

Battery quantity and inverter size should be selected according to required storage capacity, backup duration, solar array capacity, peak load and continuous load requirements.

Applications for OCEE5K Floor-Standing LFP Battery

Residential Solar Energy Storage

The 5.12kWh battery can be integrated into compatible residential photovoltaic systems for solar energy storage and increased use of locally generated solar power.

Home Backup Power

When paired with a compatible hybrid or off-grid inverter, stored battery energy can be used to supply selected backup loads according to the inverter configuration and available battery capacity.

Off-Grid Solar Systems

The 51.2V battery platform can be incorporated into professionally designed off-grid photovoltaic systems using compatible solar charging and inverter equipment.

Small Commercial Battery Storage

One or more compatible battery units can be evaluated for small commercial storage projects where system energy capacity, inverter power and battery current requirements are appropriately matched.

Space-Constrained Indoor Installations

The 140mm slim enclosure depth is particularly useful where battery installation depth is restricted, including suitable utility rooms and compact indoor equipment areas.

How to Match OCEE5K with an Inverter

First, verify that the inverter supports a 51.2V nominal low-voltage LFP battery with an operating range compatible with 40.0V to 58.4VDC.

Next, compare the inverter's battery charging and discharging limits with the OCEE5K's 50A maximum continuous charge current and 100A maximum continuous discharge current.

Finally, confirm that the exact inverter model supports the required CAN or RS485 communication protocol.

           Check Inverter Compatibility        

How to Select Battery Capacity

Battery capacity should be selected according to daily energy consumption, required backup duration, inverter power, solar generation and the loads that need to remain powered.

One OCEE5K provides 5.12kWh of nominal energy. Where parallel expansion is approved for the final system configuration, additional battery units can increase the nominal battery-bank capacity.

Usable stored energy should be calculated from the permitted battery operating window and system settings rather than nominal capacity alone.

UN38.3 and MSDS Documentation

The current product datasheet lists UN38.3 and MSDS documentation for the OCEE5K.

Importers and distributors should confirm the documentation required for the selected shipping method, destination country and local battery regulations before shipment.
