The OUPES Mega 1 Lite 2000W is a portable power station designed for off-grid power needs. To turn the unit on or off, press and hold the main power button for 3 seconds. The device features an EPS (Emergency Power Supply) function enabled by default, which provides power within 20ms during outages, provided the total load is under 2000W. Always ensure the device is placed on a stable, flat surface and kept away from water, heat, and dust.
Product Overview
The front panel includes the LCD screen, cigarette lighter output, main power button, IOT button, AC output sockets, and USB-A/USB-C ports. The rear panel contains the solar/car input port, AC input port, and AC input overload protection button.
Operation
Powering Devices: Connect your devices to the appropriate ports (AC, DC, or USB). Press the corresponding power button to activate the output. Always disconnect loads and turn off the output after use.
Frequency Switching: To change the AC output frequency (50Hz/60Hz):
- Turn off AC and DC output power.
- Simultaneously press and hold the DC output power button (USB side) and the main power button for 3-5 seconds until the frequency sign flashes.
- Press the AC output power button to select 50 or 60.
- Long press the main power button to confirm; "SUC" will flicker to indicate success.
- Long press the main power button to exit setting mode.
Charging Methods
AC Charging: Connect the AC charging cable to the AC input port. If the AC input over-current protector pops out, disconnect connections, ensure input current is below 25A, and press the protector button to resume.
Solar Charging: Connect solar panels to the solar input port. Ensure the open-circuit voltage of the solar panel is below 78V. Adapter cables are required and sold separately.
Cigarette Lighter Charging: Start the vehicle first, then connect the cable to the car's cigarette lighter and the power station's input port.
