Greetings to you knowledgeable folk,
I have been given two failed inverters, 24v Dc powered, which have failed in service.
The load was apparently a refrigerator. One inverter had blown fuses on the dc side and four MOSFETS? shorted and a circuit track to the driver transistors burnt off board.
I have not yet opened up the other unit but it was used on the same load.
My query relates to the suitability of non sine wave inverters driving loads such as fridge motors or other such inductive loads.
Can you enlighten me as to any restrictions on the loads attached to these inverters before the owner buys another one and it fails also.
I doubt if they are worthwhile repairing but I am interested to find out the failure mode.
