My dominican made fancy inverter finally burnt after 4 years of rough usage.
I was surprised to see it blow up in front of my eyes when it worked flawlessly for so many years. Its a domincian made fine inverter which was supposed to be burn-proof no matter what load you connect.
So I come and find total darkness. I notice that lights were on in the street so why the inverter is dead? I simply pressed the reset button and was glad to see inverter come back to life. But I heard some buzzing sound and smelled something burning inside. More buzzing and rattling of transformer. I should have turned off the unit off but I was curious to see what would happen next. Then my wish was answered, a loud flashy boom and everything went dead. So I disconnected the inverter and opened it up to see what was the foul burning smell was all about, and to see what got burnt.
To my surprise, the culprit was not bad engineering design but something that no engineer could provide protection for. Seems like a lizzard was living inside my inverter. It finally made its way to the wires which carried high current and 120 volts. The lizzard made a short circuit and fried instantly. At that point the trip (reset) button popped and saved the inverter but then came my engineering idiocracy. I reseted the unit and turned it on again. The short fried the lizzard some more and the high current draw blew up all my power transistors (ICs). So i guess it would set me back 800-1000 pesos to have my unit repaired and working again.
