This is Low Frequency type 2KW pure sine inverter. The Capacitor replacement has been skipped in video. Watch in another video for capacitor. replacement.
Sir, what are the values of the labeled R1 and R2 in the power board? The white one, I think those are some kind of ceramic resistors? Those were terebly busted in our inverter so we can't read the values.thanks
I was wondering what you repaired on this unit. Im working on an ultimate power brand inverter that is the same form factor. Probably the same pcb manufacture.
I realized that the thick red and black wire is connected separately on the heat sink and each of the heat sink have six mosfets while the other heat sink have twelve mosfts connected on the same heat sink and also I saw two electrolytic capacitors in between the heat sink, kindly explain in detail the circuit connection and reason behind it. Thank you
Hello Sir, nice video ! maybe you can help on the following : My victron Phoenix Inverter 12v 750va just doesn't want to start, no led, no noise... I decided to open it and everything seems to be fine : the 3 30A fuses, the small fuse in the switch circuit, all mosfets and diodes. I basically see no short anywhere. It seems more of on open circuit somewhere as no voltage go to the drive board. Any idea where to look at ? are there any other fuses ? Thank you
Hi. you might need to check the voltage in every section of inverter start from incoming fuses till the driver circuits. There might have regulator circuit which supply for protection section/driver section etc...
@@kHUNROMA OK thanks, the board has a kind of protecting orange paint that hides everthing. Any idea how to deal with this protection without damaging the board ? thanks.
