OCE-AIO2004 Key Specifications

Integrated 2kW Inverter and 4kWh Battery

The OCE-AIO2004 combines energy storage, AC inverter output, solar charging and AC charging within a single enclosure, reducing the number of separate major components required in a small energy storage system.

Rated AC output power is 2000W, while the integrated battery provides 4kWh of rated energy.

Actual usable battery energy and backup duration depend on battery operating limits, connected load, inverter losses, operating temperature and system settings.

4000W Surge Power for Short Starting Loads

The integrated inverter provides 4000W surge power for short-duration load demand.

Published battery-mode overload capability is 60 seconds at 102%-110% load, 10 seconds at 110%-130%, 3 seconds at 130%-150% and 0.2 seconds above 150%.

Motor-driven equipment should be evaluated using both continuous operating power and actual starting-current requirements.

Pure Sine Wave AC Output

The OCE-AIO2004 provides pure sine wave AC output with selectable 208V, 220V, 230V or 240V configurations.

Output frequency is specified at 50Hz or 60Hz ±0.1%, with a power factor of 1.

3000W MPPT Solar Input

The integrated MPPT solar charger supports up to 3000W of PV input power and a maximum PV input current of 18A.

This allows the PV array to be sized independently from the 2kW AC output rating while remaining within the published solar input limits.

30-400VDC MPPT Operating Range

The OCE-AIO2004 provides a wide 30-400VDC MPPT operating range with a maximum PV open-circuit voltage of 450VDC.

Solar string design should account for module open-circuit voltage at the lowest expected site temperature so that calculated string Voc remains below the 450VDC maximum input limit.

Maximum PV input current should also remain within the published 18A limit.

100A PV and AC Charging

Maximum PV charging current is specified at 100A and maximum AC charging current is also 100A.

The maximum combined PV and AC charging current is 100A, so the two sources should not be interpreted as providing 200A combined charging.

Actual charging power depends on the integrated battery voltage, state of charge, charging limits and operating conditions.

10ms UPS Transfer for Compatible Backup Loads

The published transfer time is 10ms, allowing rapid transition between available AC input and inverter output during a utility interruption.

Equipment with strict continuity requirements should be checked against the equipment manufacturer's permitted transfer time before it is connected as a critical backup load.

The system should not be treated as a zero-transfer online UPS unless that operating mode is separately confirmed for the required application.

Wide AC Input Range

Rated AC input voltage options include 208V, 220V, 230V and 240V with L + N + PE connection.

The published AC input-voltage range is 90-280VAC in normal mode and 170-280VAC in UPS mode, with 50Hz or 60Hz automatic frequency adaptation.

Hybrid On-Grid and Off-Grid Operating Modes

The current product datasheet lists hybrid on-grid and off-grid operating modes for the OCE-AIO2004.

Grid-connection requirements, export capability and applicable electrical approvals vary by destination market and system configuration and should be confirmed before project installation.

Built-In WiFi and LCD Monitoring

Built-in WiFi supports compatible smart-app monitoring, while the integrated LCD provides local operating information.

RS232, RS485 and CAN communication interfaces are also provided for system communication and compatible equipment integration.

Required communication functions and external equipment compatibility should be confirmed for the final project configuration.

Four-Wheel Floor-Standing Design

The OCE-AIO2004 incorporates four caster wheels to assist with controlled positioning of the 60kg system during installation and servicing.

Product dimensions are 445 × 240 × 592mm, providing an integrated inverter and 4kWh battery within a relatively compact floor-standing enclosure.

The wheels are intended to assist positioning on suitable level surfaces. Electrical connections, PV wiring and any fixed AC connection should be completed according to the installation requirements.

IP21 Indoor Installation

The OCE-AIO2004 has an IP21 ingress protection rating and is intended primarily for protected indoor installation.

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

The unit should not be treated as an IP65 outdoor energy storage system.

Environmental Operating Conditions

The published operating-temperature range is -10°C to +50°C, with relative humidity from 5% to 95% non-condensing.

Storage temperature is specified from -15°C to +60°C.

Maximum operating altitude is 4000m, with derating required above 1000m.

Typical Energy Storage System Applications

Residential Backup Power

The integrated 4kWh battery and 2kW inverter can support selected residential backup circuits when the connected load remains within the system's continuous and surge limits.

Small Office Backup

The system can be evaluated for compatible lighting, networking equipment, computers and other appropriately sized office loads requiring battery backup.

Off-Grid Cabins and Remote Buildings

The integrated MPPT solar charger, battery storage and pure sine wave inverter can be used in professionally designed off-grid systems where load and solar-array requirements match the OCE-AIO2004 specifications.

Mobile Indoor Backup Applications

The wheeled enclosure can assist with positioning the system in suitable protected indoor locations where installation or service access may change.

How to Size the PV Array

The OCE-AIO2004 supports up to 3000W of photovoltaic input power, but PV array design must also satisfy the inverter's voltage and current limits.

Operating PV string voltage should remain within the 30-400VDC MPPT range and maximum open-circuit voltage must remain below 450VDC under the lowest expected site temperature.

Maximum PV input current is 18A. Module Voc, Vmp, Isc and Imp should therefore be checked before selecting series and parallel string configurations.

How to Plan Backup Loads

Continuous connected load should remain within the 2000W rated AC output of the OCE-AIO2004.

Equipment with motors, compressors or other high starting-current loads should also be checked against the 4000W surge rating and published overload limits.

Backup duration should be calculated from actual load energy consumption and usable battery energy rather than a fixed number of operating hours.
