Color LCD System Monitoring

The OCE-ESS-500W-D adds a color LCD digital display for direct system monitoring without requiring an external mobile application.

The current product information describes display functions including battery state of charge, battery voltage, charging and discharging information, output power, operating status and alarm information.

The display interface gives operators a clearer view of current system condition than basic multi-level battery indicators.

500W Pure Sine Wave AC Output

The integrated inverter provides 500W of continuous pure sine wave AC output for compatible low-to-medium power loads.

Typical compatible loads can include laptops, routers, communications equipment, LED lighting, televisions, chargers and other equipment whose combined continuous demand remains within the 500W system rating.

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

Dual Schuko AC Output Sockets

Two Schuko AC sockets provide grounded AC connections for compatible European electrical equipment.

The system's 500W output rating applies to the combined AC load rather than 500W per socket.

Buyers should confirm the required socket and electrical configuration for the destination market before ordering.

36W Multi-Protocol USB-C Output

The display version adds a USB-C output with up to 36W of published charging power.

The current specification lists PD3.1, PPS and QC3.0 multi-protocol support for compatible USB-C devices.

Actual charging power depends on the connected device, cable and supported charging protocol.

Dual 12V DC Output Ports

Two round DC output ports provide additional direct-current connections for compatible 12V equipment.

Direct DC output can be useful for appropriately rated lighting, communication equipment, routers, monitoring devices and other low-power DC loads.

The electrical rating of the connected device should be checked against the supplied DC output specification before use.

1004.8Wh LFP Battery

The OCE-ESS-500W-D provides 1004.8Wh of nominal stored energy using LFP battery chemistry.

The published battery configuration is 3.2V and 314Ah. This configuration provides approximately 1kWh of nominal battery energy for portable backup and off-grid applications.

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

500W AC Charging

Maximum published AC charging power is 500W.

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

Charging time should therefore be evaluated under the actual operating conditions rather than treated as a fixed value.

300W MPPT Solar Charging

The integrated MPPT controller supports up to 300W of photovoltaic charging power.

The published solar input range is 10-55VDC with a maximum input current of 10A.

Solar module Voc, Vmp, Isc and Imp should be checked before connection to ensure the selected photovoltaic source remains within the system voltage, current and power limits.

Up to 20ms Backup Transfer

The OCE-ESS-500W-D has a published backup transfer time of up to 20ms.

This allows rapid transition to battery-backed inverter power 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.

88% Maximum Inverter Efficiency

Maximum inverter conversion efficiency is specified at 88%.

Actual conversion efficiency varies with battery condition, connected load, operating temperature and system operating mode.

Compact 11kg Portable Design

The OCE-ESS-500W-D measures 210 × 156 × 376mm and weighs approximately 11kg.

Its compact format supports transport between homes, offices, vehicles, temporary workplaces, outdoor locations and other applications where a permanently installed storage system is not required.

Published packaging dimensions are 262 × 212 × 432mm with a gross weight of approximately 12kg.

Low-Noise Operation

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

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

Integrated Protection Functions

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

The LCD interface can provide system-status and alarm information to assist the operator in identifying abnormal operating conditions.

-10°C to +50°C Operating Temperature

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

Available charging and discharging performance can vary with battery temperature and other operating conditions.

Typical Applications

Essential Home Backup Loads

Compatible routers, lighting, laptops, communication devices and other low-power equipment can be supplied during temporary power interruptions when total AC demand remains within the 500W system rating.

Camping and Caravan Power

The compact enclosure, photovoltaic charging input, Schuko sockets, USB-C connection and DC outputs provide multiple connection options for compatible camping and caravan equipment.

Mobile Office and Remote Work

The system can support compatible laptops, network equipment, displays, chargers and communications devices where portable stored energy is required.

Small Retail and Event Applications

Point-of-sale equipment, small displays, lighting and communications hardware can be considered when combined continuous demand remains within the rated system output.

Field Service and Portable Equipment

The combination of AC, USB-C and DC outputs can support compatible test equipment, battery chargers, communications devices and other low-power equipment used at temporary or remote work locations.

How to Select a Compatible Solar Panel

The photovoltaic source should remain within the 10-55VDC input range, 10A maximum current and 300W maximum solar charging power.

Check the solar module Voc, Vmp, Isc and Imp before connection rather than selecting a panel only according to its rated wattage.

Voltage and current must remain within the published input limits under the expected operating conditions.

How to Estimate Backup Runtime

Backup runtime depends on the actual energy consumption of the connected equipment and the usable energy available from the battery.

The system provides 1004.8Wh of nominal battery energy, but nominal capacity should not be interpreted as 1004.8Wh of guaranteed AC output because inverter conversion losses and battery operating limits must also be considered.

Use the actual wattage and required operating time of each load to calculate the required energy in watt-hours.
