January 1, 20251 yr Dear readers, My Voltronic inverter equipment decided to stop working after 7 years. The charger part, without switching on button, still works, but once I switch-on the power button, and try to invert the current, starts the alarm with error code 09. Initially, when the equipment abruptly stopped with weak load, I could read the 05 error code before shut down. I disconnected AC out wires and measured the voltage, however, it does not provide any volt while alarm is signing. I opened the inverter and I could not see any burnt part. Can you suggest any other part I should check before buy another equipment? :-/ Thanks so much in advance for your help.

You have had great service out of the inverter 😀 This is one for @BritishRacingGreen or @Coulomb

That's where you usually see the worst carnage. In this case, you should also check the IGBTs on the middle heatsink. Sometimes the damage is fairly subtle, like a crack in the epoxy. Unless you are handy with electronics, fir example you have access to a desoldering station, it's probably time to retire this inverter.
January 2, 20251 yr Author You are always so helpful! I will buy now another equipment, and eventually, with more time I would check everything you have mentioned. Always good to have a spare inverter if I could fix it. Thanks again!
