Inverter/Charger Working Principle & Applications
Tips: Daily Maintenance of Power Inverters
1. Check whether the load is within the rated power, the voltage range and current of the power inverter.
2. Maintain your inverters properly and regularly: use wet cloth to wipe out the external dust and dirt of the inverter; tighten the screw of the DC input terminal; use high-pressure air gun to clean up the internal dust and foreign matter.
3. Inverter must be turned off when cleaning and maintenance is carried out.
4. In the process of maintaining inverters, it is best to do the following:
- First, periodically check whether the line part is intact. If there is something abnormal, it is necessary to timely replace.
- Secondly, in the process of using the inverters, it is necessary to stop and check immediately if there is a problem. Only after the problem is solved, can the inverters continue to be used.
- Thirdly, in the process of maintenance, the failure of unknown cause should be recorded in advance, and then ask the manufacturer to deal with it.
- Fourth, when cleaning inverters, it is necessary to use soft cloth for scrubbing, not to use too much friction scrubbing tools.
- Fifth, periodically check whether its heat sink and seal are blocked or not. If so, dust should be disposed of in time.
