2009.6Wh LFP Battery Capacity

The OCE-ESS-1000W provides approximately 2kWh of nominal LFP battery energy for applications where longer runtime is required but continuous AC demand remains within 1000W.

The current product specification describes two 3.2V, 314Ah LFP cells connected in series, creating a nominal 6.4V battery platform with 2009.6Wh of stored energy.

Actual usable AC energy depends on battery operating limits, inverter conversion losses, state of charge, temperature and the connected load profile.

1000W Pure Sine Wave Output

The integrated inverter provides 1000W continuous pure sine wave AC output.

Compatible applications can include computers, communication equipment, televisions, lighting, battery chargers, office equipment and other devices where total continuous demand remains within the 1000W rating.

Appliances with motors, compressors, heating elements or high startup current should be checked against their actual startup requirements before connection.

Two AC Output Sockets

Two universal AC output sockets allow multiple compatible devices to be connected at the same time.

The 1000W rating applies to the combined continuous output of the system rather than 1000W per socket.

One 5V / 1A USB output is also provided for compatible low-power electronic devices.

1000W AC Charging

Maximum published AC charging power is 1000W.

The current product information lists an AC input range of 90-270VAC and a frequency range of 45-65Hz.

Actual recharge time depends on available AC input power, battery state of charge, charging control, battery temperature and other operating conditions.

500W MPPT Solar Charging

The integrated MPPT solar charger supports up to 500W of photovoltaic charging power.

The published photovoltaic input range is 12-55VDC with a maximum PV input current of 15A.

This provides more solar charging capacity than the OCE-ESS-500W model while retaining a portable low-voltage PV input architecture.

12-55VDC PV Input Range

The connected photovoltaic module or array must operate within the 12-55VDC input range and 15A maximum input-current limit.

Solar module Voc, Vmp, Isc and Imp should be checked before connection instead of selecting panels by wattage alone.

The current product information lists an XT90E-M connection for photovoltaic input.

Up to 20ms Backup Transfer

The OCE-ESS-1000W provides a published backup transfer time of up to 20ms.

This allows rapid transition to battery-backed inverter output for compatible equipment when normal AC input is interrupted.

The system is not a zero-transfer online UPS. Equipment with strict continuity requirements should be checked against the equipment manufacturer's permitted transfer time before use.

90% Maximum Inverter Efficiency

Maximum inverter conversion efficiency is specified at 90%.

Actual efficiency varies with load power, battery state of charge, voltage, temperature and operating mode.

Integrated Battery Protection

Published protection functions include undervoltage protection, overvoltage protection, short-circuit protection and over-temperature protection.

These protection functions monitor electrical and thermal conditions and can limit or stop system operation when applicable protection thresholds are reached.

Compact 19kg Portable Design

Product dimensions are 240 × 225 × 355mm and net weight is approximately 19kg.

The compact enclosure allows the system to be transported between residential, office, vehicle, temporary work and other compatible applications where permanent energy storage installation is not required.

Due to the 19kg weight, appropriate handling methods should be used when the unit is moved frequently.

Low-Noise Operation

Published operating noise is below 40dB measured at a distance of one meter.

Actual noise level can vary with load, charging power, internal temperature and cooling-system operation.

-10°C to +50°C Operating Temperature

The published operating-temperature range is -10°C to +50°C.

Charging and discharging capability can be affected by battery temperature and operating conditions, particularly near temperature limits.

Typical Portable Energy Storage Applications

Essential Residential Backup Loads

The system can provide stored power for compatible lighting, routers, communication equipment, computers, televisions and other selected residential loads during temporary power interruptions.

Small Office and Retail Backup

Compatible networking equipment, laptops, point-of-sale devices, lighting and other appropriately sized business loads can be considered where total continuous power remains within 1000W.

Outdoor and Mobile Power

The portable enclosure and 500W solar charging capability make the unit suitable for compatible camping, vehicle-based, outdoor event and remote-work applications.

Field Service and Temporary Work

Battery chargers, test instruments, communication devices and compatible low-to-medium power tools can be evaluated for temporary or remote work locations.

Rental and Emergency Power Fleets

The approximately 2kWh storage capacity and portable enclosure can be considered for rental and emergency-power fleets that require repeatable low-to-medium power battery operation.

How to Select a Compatible Solar Panel

Solar input is limited to 500W, 12-55VDC and 15A.

Check photovoltaic module Voc, Vmp, Isc and Imp before connecting a panel or array to the OCE-ESS-1000W.

The photovoltaic source should remain within all voltage, current and power limits under the expected operating temperatures.

How to Calculate Backup Runtime

Backup runtime depends on actual connected-load energy consumption and the usable AC energy available from the battery.

The nominal battery capacity is 2009.6Wh, but this value should not be interpreted as 2009.6Wh of guaranteed AC output because inverter conversion losses, battery operating limits and system consumption must also be considered.

For system planning, calculate the watt-hours required by each essential load based on its actual power consumption and expected operating time.

How to Check Appliance Compatibility

Add the continuous power of all devices that may operate simultaneously and keep total demand within the 1000W rated output.

Refrigerators, compressors, power tools, pumps and appliances with heating elements can have operating or startup requirements that exceed their typical average power consumption.

Verify the appliance nameplate and startup characteristics before using the OCE-ESS-1000W with higher-load equipment.
