MOSFET और रिले (Relay) की टेस्टिंग कैसे करें? Dead Inverter को स्टेप-बाय-स्टेप ठीक करने का तरीका। अगर आप इलेक्ट्रॉनिक रिपेयरिंग सीखना चाहते हैं या अपनी दुकान चलाते हैं, तो यह वीडियो अंत तक जरूर देखें। Indicator Problem Solution Mains ON (Not Glowing) Inverter working on battery but not charging. Check the input plug, main fuse/MCB of your house, and the glass fuse at the back of the inverter. Overload Too many appliances are running. Turn off high-load devices (fans, extra lights). Reset the power button on the front. Batt. Low Battery is discharged. Wait for the mains power to return so it can charge. If it happens too fast, your battery may be weak. Fuse Blown Input power surge. 2. Common Technical Faults (Repair Guide) If the indicators aren't enough, here are the internal issues usually handled at a service center: Dead Inverter (No Power) Check Battery Connections: Ensure the terminals are tight and free of carbon (white/green powder). Clean with hot water if necessary. Deep Discharge: If the battery voltage drops below 10.5V, the inverter won't turn on. You may need an external charger to "boost" the battery. Inverter Not Charging (But Mains is OK) Blown Charging Fuse: Check the internal fuse on the PCB. Relay Chattering: If you hear a "tick-tick" sound, the internal relay might be faulty or the input voltage is too low/high. No Output in UPS Mode MOSFET Failure: This is the most common hardware failure. If you hear a loud pop or smell burning, one or more MOSFETs on the heat sink have likely shorted. Driver IC Issue: If MOSFETs are replaced but it still doesn't work, the driver circuit (Microcontroller or LM324 op-amp) might be faulty. 3. Maintenance Tips Water Level: Regularly check the distilled water levels in your battery. Cooling Fan: Ensure the fan at the back is spinning. If it gets stuck with dust, the unit will overheat and trip. Main Switch: If the front button is loose or non-responsive, it usually needs a simple micro-switch replacement on the front panel board.
