How to Fix Pure Sine Wave Inverter?

Pure sine wave inverter applies in the long term, it is inevitable due to the combined effect of a number of internal and external factors and the emergence of certain failure, thus affecting the normal use of the device. Then, we need to find specialized service personnel to repair the fault detection. Maintenance is also an important part to ensure normal use.

In the following, ATO automation will tell you how to fix it.

• Troubleshoot a faulty power switch. When a power inverter isn't turning on after pushing the power switch, the problem might be with the switch! At first, you have to check if it's okay or not, and the process is simple to do. Unplug the power inverter from its power source, plug in another appliance to it, and turn it on. If it doesn't turn on, you have to get a replacement for the power switch. Call a professional electrician and get a replacement unit for the switch to change it. If you're okay with doing it yourself, you can replace it yourself as well.
• Check the battery connections. If you're using the setup for a long time, and the pure sine wave power inverter isn't working or turning on, the fault might be with the battery. Most of the time, the problem is a loose connection to the battery, which requires you to clean and tighten it up. If the problem isn't with the connector, the battery might have rusted or corroded. Inspect the battery and check for corrosion, if there are any, disconnect and take the battery out and clean it. To clean it, take some baking soda, mixed with hot water, take a stiff toothbrush and scrub the terminal with it after dipping in the mixture. Once the corrosion is removed, clean the connectors and dry them with a paper towel. Reconnect them and try turning the inverter again.
• A discharged or faulty battery. The fault may not be with the sine wave inverter at all in the first place when your power inverter isn't working. The problem might also be with the battery, especially if you're running it for a long time. The battery might have been weakened and discharged quickly, or it might have a fault inside. If your battery is weak, you might have to get it replaced or repaired if possible. If the battery is lead-acid based and running out of acid, you have to get it acid replacement, and that'll be enough.
• Diagnose the sine wave inverter. If the problem isn't in the power switch or the battery, it might be in the inverter itself, and you have to run a diagnosis to resolve that. The best way to do that after getting to know how the system works, get a diagram of the inverter. Once you have the diagram, it's time to check the contact points one by one after opening the housing up. If you find the contact points seem good, move on to the rest of the components. You have to test the voltmeter, followed by the other components.
• Test the power inverter. Once you have the new parts installed to the old faulty parts and shouldered on the places if necessary, now is the testing time. Connect the inverter to your battery and plug it in a controlled and limited power like a low voltage lamp. Now, use a voltmeter to get the reading of the inverter output and see if it works fine. If everything is okay, the machine should work perfectly, and the lamp should light up as well.
