To Next PageTo Next PageWhat to do if the HQ HQ-INV4000-12 Inverter has no voltage output and the OVER LOAD indicator light is on?
If your HQ Inverter shows no voltage output and the OVER LOAD indicator is lit, the possible causes are a short circuit or wiring error, or a very high power load. Check the AC wiring for a short circuit or improper polarity. You may also need to remove or reduce the load.
Why HQ Inverter has no voltage output and POWER indicator no light?
If your HQ Inverter has no voltage output and the POWER indicator is not lit, several issues could be the cause. First, ensure the inverter is switched on. If it is, check the wiring to the inverter and battery to make sure they are properly connected and providing power. It's also possible that the internal fuse is open or that there's reverse DC polarity. For these last two issues, you should have a qualified electrician check and replace the fuse, while observing correct polarity.
How to stop the low battery alarm on the HQ HQ-INV4000-12 Inverter?
If the low battery alarm on your HQ Inverter is constantly on and the VOLTS indicator is below 10.5 V (or 21 V for 4000 W/24 V inverter), it could be due to poor DC wiring or the battery condition. Ensure you are using the proper cable and making solid connections. Also, consider changing the battery or using a new one.
What causes low voltage output and AMPS indicator in red zone on HQ Inverter?
The cause of low voltage output and the AMPS indicator being in the red zone on your HQ Inverter is overload. To resolve this, reduce the load on the inverter.
What to do if HQ HQ-INV4000-12 has no voltage output and VOLTS indicator in lower red zone?
If your HQ Inverter has no voltage output and the VOLTS indicator is in the lower red zone, it indicates low voltage input. Recharge the battery and check the connections and cable.
What causes OVER TEMP light and no voltage output on HQ Inverter even with normal load?
If your HQ Inverter shows no voltage output and the OVER TEMP indicator is lit, even with a load less than 4000 W/250 amperes (or 125 A for a 4000 W / 24 V inverter), the issue might be thermal shutdown. Ensure that the ventilation openings in the inverter are not blocked and try to reduce the ambient temperature.
Why HQ HQ-INV4000-12 shows OVER TEMP and no voltage output when overloaded?
If your HQ Inverter is showing no voltage output and the OVER TEMP indicator light is on, with a load exceeding 4000 W/250 amperes current input (or 125 A for a 4000 W / 24 V inverter), the inverter likely experienced a thermal shutdown. To fix this, allow the inverter to cool down. If you require continuous operation, reduce the load.
What does it mean if HQ HQ-INV4000-12 Inverter has no voltage output and VOLTS indicator in upper red zone?
If your HQ Inverter has no voltage output and the VOLTS indicator is in the upper red zone, it indicates high voltage input. Ensure that the inverter is connected to a 12 V battery (or 24 V for a 4000 W/24 V inverter) and check the regulation of the charging system.
