Instructions for use
Powering On/Off: Long press the power button to turn the unit on or off. The LCD screen will light up when powered on.
Activating Functions: With the main power on, lightly press the separate button for each function (AC output, DC output, etc.) to activate it. The corresponding icon will appear on the LCD screen. Press the button again to deactivate the function.
Notices:
- A short press of the main power button turns off the LCD screen but keeps the product running.
- The product enters sleep state and the LCD screen turns off automatically if no operation occurs within 5 minutes. The LCD screen will light up again upon any load change or operation.
- The default standby time is 12 hours. The product will shut down automatically after 12 hours. Standby time can be adjusted via the OUPES APP.
Recharge Methods
AC Charging
Use the included AC charging cable to charge the device. Connect it to an AC wall outlet with a current of at least 16A. The device supports fast charging up to 1800W and can be fully charged in approximately 1.7 hours.
Fast Charging & Slow Charging Switching:
- Ensure the product is turned on and all input/output ports are off.
- Simultaneously press the IOT button and the left DC button for 3-5 seconds. The LCD screen will display 'SET'.
- Lightly press the IOT button to switch between 'L' (slow charging, 900W input) and 'H' (fast charge, 1800W input).
- Press and hold the POWER button for 3-5 seconds to confirm. The LCD screen will display 'SUC' upon successful setting.
- Press and hold the POWER button again for 3-5 seconds to exit the setting menu.
Note: Use only the provided AC charging cable. Ensure the wall outlet provides at least 16A. OUPES is not liable for issues arising from using other cables or improper voltage.
Solar Charging
Connect up to 6 standard solar panels using the Anderson-MC4 cable and MC4-7909 cables. Full charge is estimated in about 2.5 hours with 6 x 240W solar panels.
Notice:
- Solar charging cable (MC4-7909 cable) and solar panels must be purchased separately.
- When using matching solar panels, connect them according to this user manual.
- Before connecting solar panels, confirm the open circuit voltage is within 150V to prevent product damage.
Car Charging
Charge the product using the car charger port (12V/8A). To protect the car battery, charge only after the car engine has started. Ensure a secure connection between the car charger port and the cigarette lighter input cable. OUPES is not responsible for losses due to non-compliance with standard operation.
Power Pack Charging
Connect the power station and the battery pack using the dedicated cable. The LCD display will show charging power when charging begins. The battery pack can also be charged independently via solar or car charging. The battery pack is sold separately.
Notice:
- Ensure both the product and power pack are turned off before connecting.
- After connecting, verify the LCD displays input power before use.
- Do not connect or remove the power pack during charging or discharging. Turn off the power before operating.
- Avoid touching the metal terminals of the power pack connection port with hands or objects. Clean any foreign objects with a dry cloth.
Other Functions
EPS (Emergency Power Supply)
The product supports EPS (emergency power backup). When connected to the power grid via the AC input port and AC charging cable, connected appliances will run on grid power. If the grid power is cut off, the product automatically switches to battery power within 20ms.
Notice: This is a non-professional UPS function and does not support 0ms switching. Do not connect devices requiring high uninterrupted power (e.g., data servers). It is recommended to use only one device at a time, with a combined operating power not exceeding 2200W. Overload protection will activate if limits are exceeded. OUPES is not responsible for data loss or malfunction due to improper use.
Frequency Switching
To switch frequency:
- In the power-on state, turn off AC output.
- Simultaneously press the main power button and the DC button (USB output) to enter the frequency menu.
- Press the AC output button to cycle through frequencies; the selected frequency will flash.
- Long press the main power button to set the frequency. 'SUC' will display upon success.
- Long press the main power button again to exit the menu.
Disconnection Switch
The circuit breaker disconnects the load circuit and fault circuit to prevent accidents and ensure safe operation. It automatically disconnects in case of electrical overload or abnormal operation.
- Turn on the AC IN switch when charging via mains electricity.
- Turn on the AC OUT switch when using AC output; otherwise, there will be no output.
- Turn on both AC IN and AC OUT switches for EPS function (Load takes precedence over charging, with charging+load < 2200W).
FAQ
- What battery does the product use?
It uses high-quality lithium iron phosphate batteries (LiFePO4). - What devices can the product's AC output port power?
With 3600W rated power and 7000W peak power, it can power most household appliances. Confirm the power requirements of your appliances and ensure their total power consumption is below the rated power. - How long can the product charge my devices?
The estimated charging time is shown on the product's LCD screen based on stable power usage. - How can I know if the product is charging?
The remaining charging time will be displayed on the LCD screen. The charging indicator icon will rotate, showing the remaining battery percentage and input power. - How to clean the product?
Gently wipe with a dry, soft, clean cloth or paper towel. - How to store the product?
Store in a dry, ventilated place at room temperature, away from water and heat sources. For long-term storage, discharge and charge every three months (discharge to 0%, fully charge, then discharge to 60%). Products not maintained for over 6 months may void the warranty. Do not store in temperatures above 45°C or below -10°C for extended periods. If the battery is severely low due to long idle periods, it may enter deep sleep mode; recharge before use. For long-term storage, place horizontally. - Can this product be taken on the plane?
No. - Is the actual output capacity consistent with the user manual?
The user manual states the rated capacity. Due to efficiency losses during charging and discharging, the actual output capacity may be lower than the specified capacity.
