Frequently Asked Questions - INV300WU12F HQ

What devices can I connect to the INV300WU12F inverter?

You can connect devices with a total power of less than 300 W continuous (350 W for 30 minutes max). This includes computers, TVs, lamps, radios, chargers, etc. Avoid high-power devices like refrigerators or power tools.

How do I connect the inverter to a car battery?

Insert the cigarette lighter plug into the car's cigarette lighter. Ensure the battery is in good condition and the engine is running for prolonged use to avoid complete discharge.

What does the flashing red LCD light mean?

A flashing red light indicates overload or overheating. The inverter has shut down to protect itself. Disconnect some devices or let it cool down before restarting.

Why won't the inverter turn on even though it is plugged in?

First check the fuse in the cigarette lighter plug. If it is blown, replace it with an identical 15 A fuse. Also check the connections and battery voltage.

Can I use the inverter with a 24 V battery?

No, the INV300WU12F model is designed for 12 V input only. There is a 24 V version (INV300WU24F) for 24 V batteries.

How do I charge a device via the USB port?

Simply connect your device's USB cable to the inverter's USB port. The port provides 5 V / 500 mA, ideal for charging smartphones, tablets, or other small devices.

What should I do if the 'low battery' alarm goes off?

The alarm indicates that the battery is reaching a low level (10.5 V). Start the car engine to recharge the battery or reduce the load. If the voltage continues to drop, the inverter will automatically shut down.

Is the inverter waterproof or moisture resistant?

No, it should be installed in a dry, ventilated environment, away from water, oil, and direct heat. Do not expose to rain or moisture.

How do I clean the inverter?

Use a dry cloth to clean the device. Never use solvents, abrasive cleaners, or liquids. Unplug it before cleaning.

Does the inverter produce a pure sine wave?

No, this model outputs a modified sine wave. It is suitable for most simple electronic devices, but may not be suitable for sensitive equipment like pumps or some chargers.

When using for longer periods it is wise to have the engine of the car running, to prevent a fully discharged battery. When the alarm for low battery starts, start the car engine to continue using the inverter and connected appliances.

Make sure that the maximum power demand of the connected apiances does not exceed the output power of this inverter (300W continuously, 350W for max. 30 minutes)

1. 

First switch on inverter after switching on the inverter, switch on appliances

Always make sure to turn on the power of the inverter first, before turning on the power of the connected equipment.

1. 

Max. 35A (12V version) Max. 15A (24V version)

When the inverter and the power indicator do not work, but the power is on, check the fuse in the cigarette plug. If the fuse is spoilt, use similar fuse for replacement.

Troubleshooting

If the inverter doesn't function properly, there can be several possible reasons for it:

1) Poor contact

- Clean contact parts thoroughly

2) Inverter has no power

- Check car fuse, replace damaged fuse

- Check connection of wires

3) Fuse is blown

- The fuse is located in the DC (cigarette) plug. Replace the fuse with a similar fuse of equivalent value

4) AC output shutdown caused by overload

• Make sure the continuous load of the attached appliances does not exceed 100 Watts

5) AC output shutdown caused by overheating

• Under heavy loads for extended periods of time, the inverter will shutdown the output to prevent damage from excess heat. If this happens, please proceed as below:

(A) Switch off the power switch of the inverter

(B) Decrease load of the machine i.e. disconnect some of the appliances or wait until this inverter cools down.

(C) Switch on the power switch of the inverter.

6) Low-battery shutdown

- Recharge your battery and resume operation.

Caution!

Always place the inverter in an environment that is:

1. Well ventilated
2. Not exposed to direct sunlight or heat source
3. Out of reach from children
4. Away from water, moisture, oil or grease
5. Away from any infl ammable substances
