    Have you contacted Schneider?

    That's awful dusty for the inside of an inverter. Even if they are left outside they should be inside a reasonable environment with some air filtration. I live on a dust road and my inverters have always lived outside and are not as dusty, though they are in a box with air filtration.

    A layer of dust insulates electrical components not allowing them to cool as expected. If they can't be put in a less dusty environment. Some companies make sealed units. I know Outback for one does...

    Hi vetah,   welcome to the Forum,

    It is a bit difficult to see,   but,   it looks that the device,   circled in red,   has its top blown off,  or incinerated.   It looks like it is/was an IC.

    If the above is generally correct,   this is often caused by massive overvoltage,   or over-current.

    There a number of  things that can cause this type of situation.   Perhaps  Lightning (?).

    Just some guesses,   good luck,   Vic

    Three phase power or 3 XW's ?  I would doubt where you are, that you are close to service? I would doubt even more if there was a source of parts there for someone who was skilled and knew the part numbers. You can click on the link to Schneider solar who sell the XW's you have below. Good Luck!

    Hey Vitah,

    I'm dealing with that problem. That component is a step down DC/DC converter. It's rated for 76v, and steps battery voltage down to five volts. The part number you need is  (MAX5035BUPA+) its a IC REG BUCK 5V 1A 8DI. You might want to check the Mosfet PN (FQP19N20)  and its driver PN(UC3845AD8TR) IC REG CTRLR MULT TOPOLOGY 8SOIC to see if they're OK too.

    Check the inductor (Marked 101, 100uH) right in front of the converter and the Diode ("D19")

    I've got two boards that blew the same components.

    Good Luck!

    that whole board is the control board...or logic board...thats where the memory and firmware are

    usually schneider will not sell you a new control board...I have tried, but they might sell over seas if you are isolated enough

    inverter service center might have one....they are located in Whitehouse Tennessee USA...google them

    Ok I read some the comment, yes thats an ic max5035b that can be replaced with some other component in the circuit as well. Got it done to mine.

    Nitro25 HIii i need help with this board schneider  xantrex conext 7kw inverter 

    i need to know the value of these components regulators ic and some resistors i lost them during transport when i tried to repair it i desolder them and put them in bag and lost them 

    here is the pic of the board and the schematic component number :smile:

    here is the pic's 
    component symbols :
    U38 
    R200, R182
    U39
    R163,R162
    D23
    I think the U38,39 are regulators ic but i dont know there values , i hope you can help me
