Test the battery bank capacity and check terminal voltage balance. If you(12V, 24V, or 48V?) What appliances are you trying to run?
Connect the positive (+) DC cable to the positive terminal of the battery bank.

Keep the unit strictly dry. Do not expose the inverter to rain, high humidity, or condensation.
The battery bank is depleted. Turn off loads and charge the batteries. power jack inverter 5000w manual
Connect the chassis ground terminal to the earth ground. 4. Operating Instructions
Lead-acid batteries vent explosive hydrogen gas; ensure adequate ventilation.
The connected AC appliances exceed 5000W continuously or the surge peak capacity.
Periodically use compressed air to blow dust out of the vents to maintain cooling efficiency. Test the battery bank capacity and check terminal
A: The "Low Voltage Alarm" is triggered by voltage drop under load , not resting voltage. Cables are too thin or too long. Replace with 4/0 AWG copper (not CCA).
Usually indicates Low Voltage . Check your battery charge and cable tightness.
When the inverter detects a fault, it shuts down output and activates a red error light or audible buzzer. Problem / Error Indicator Possible Cause Corrective Action Battery voltage dropped below 10.5V (for 12V systems). Recharge battery bank. Check for loose connections. High Battery Fault DC input voltage exceeds maximum threshold. Check charge controller settings. Lower charging voltage. Overload Protection Active Connected appliances exceed 5000W continuous or peak limit. Unplug non-essential loads. Restart the inverter. Over-Temperature Fault Internal components exceeded safe heat limits. Clear vent blockages. Let unit cool for 15 minutes. No Power / No Display Blown internal fuse or complete lack of DC input. Verify inline fuse. Check battery connections and charge. 8. Preventive Maintenance
