I came home to turn my inverter on my MPOWER 2400, only to discover it made a continuous beep. On the LCD, it read fault. I opened it up, checked at the mosfet it was OK. I can't seem to rectify the issue...
a friend said that MPOWER and MERCURY modSine wave inv. Always have that issue. More like there is a duration timer that shutdown the inv when it has been used for more than a year.

Dear Doraiswamy,
nice post ,
but you need to mentioned thatb how carefully you disconnect the battery from the invetrer (you must done it).because playing with inverter without removing battery is too riskey.
always mention thes steps because every reader is not master & perfect in electronics field means some are hobbiest

Good article. I am working on an old UPS which has not been working since 2000. I will be asking for assistance from all technicians.

thanks for the post. It was very helpful. However, I am electronic hobbyist myself and I have a 2.4KVA MERCURY -24 volts modified sine wave inverter seating on my desk. the problem is that it does not really charge the batteries. the LCD indicator keeps showing that it is charging but after a while, when you check the batteries, one will discovered it has not been charged. Also the charging bars on the display indicating that the batteries are charging is suppose to simultaneously increase as the batteries are being charged. But in this case, the battery bar never goes beyond a single bar even after an extended period of charging.
thanks
