Did any of you have this before is the 1st time that happens to me ,just wish to know the value of those resistors. Schneider context 4048 :294581785_5825680427459877_7304336167396046167_n (1).jpg R19 and R31294062387_5825680380793215_5318753643423631271_n.jpgSchneidr context 4048
 
YES, resistors toast for a reason.

Guessing, it looks like they are dealing with L1/L2, in some way.

Do you know what the inverter was doing at the this time?

Was the genset running?

If grid-connected, were there grid problems, possibly during this time?

The inverter is offgrid and was running basic home tv,refrigerator,fans etc..
 
I found a doc that is 1 year + 1 year if you register the system in the first 6 mo.

I expect that there are folks on here that might be able to snap a pic of un-failed resistors, and I expect that Schneider will tell you what they are or at least sell you a replacement board.
 
Can you please provide the straight shot pictures of the top side and the bottom side of the board?
It may have something to do with the Optoisolator MOC3021 Triac output section.
 
You may want to check your warranty for sure if you registered. I would figure out why those messed up though as to prevent the same thing from happening again if it was human error .
 
Jot down all the relevant information and any board numbers you can find then write down R19 and R31 then contact them. Tech support should be able to tell you what value they are and maybe give an insight as to why it blew in the first place. You can also find out if it is under warranty.
