Ensure the unit is powered on.
Press the corresponding output button (AC, DC, USB) to activate that bank.
Connect your device cable to the appropriate port.
Monitor the LCD to ensure power is being delivered and battery level is sufficient.

Tip: Start with the highest power draw device first to avoid overloading the inverter.

Charging & Power Management

Supports AC, Solar, and Car charging methods.

AC Charging: Connect the AC charging cable to the unit and a wall outlet. The LCD will show charging status and time to full.
Solar Charging: Connect a compatible solar panel. Ensure direct sunlight for optimal charging. The MPPT controller optimizes input.
Car Charging: Connect the 12V car charging cable to the unit and your vehicle's 12V socket (engine running recommended).
Charging Status: LED indicator flashes during charge, solid green when full.
Battery Saving: Enable auto-shutdown in settings to conserve power when devices are fully charged or not in use.
Parallel Use (Optional): Some models support connecting two units for increased capacity (requires optional cable).

WARNING! Do not charge with AC and solar simultaneously unless specified. Do not exceed max input power.

Safety Features

Overload Protection: Automatically shuts off output if exceeded; reset by turning off and removing devices. Short Circuit Protection: Cuts power in case of a short. Temperature Control: Fans activate during high load; unit will throttle or shut down if overheated. Low Voltage Protection: Automatically shuts down to prevent battery damage when voltage is too low.

Care & Maintenance

Store in a cool, dry place. Clean exterior with a dry, soft cloth. Periodically perform a full charge/discharge cycle (every 3 months) to maintain battery health if storing long-term.

CAUTION! Do not disassemble. Do not expose to water or fire. Keep away from children. If the unit will not be used for more than 3 months, charge to 50-60% before storage.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit will not turn on	Battery depleted	Connect to AC power for charging. Allow 30 minutes before attempting to power on.
No output from AC ports	Overload/Inverter off	Remove all devices, press AC button to turn inverter on. Reconnect devices one by one, staying under 1000W.
Slow or no solar charging	Panel/Sunlight/Connection	Ensure panel is in direct sunlight, connections are secure, and panel voltage is within 11-28V.
LCD display is dim or off	Sleep mode/Brightness	Press any button to wake display. Adjust brightness in settings menu.
Unit beeps continuously	Overload/Overheat	Turn off unit, disconnect all devices, allow to cool in a ventilated area. Restart after 15 minutes.
Battery drains quickly	High load/Parasitic drain	Check connected device power draw. Ensure all output banks are turned off when not in use.

Reset: Turn unit off, disconnect all devices and chargers. Wait 60 seconds, then turn on.
