Ted Alva Jr Posted January 20, 2022 Share Posted January 20, 2022 See attached Image. The card with the charger board is the new one. I told Power Jack that the inverter was Special setup with a ASL4 trans. But still sent a generic card. See images. On Q3 has a broken leg on the right side was the causing the diode D12 to explode and blow the MOSFETs making it the first failing. This happened do to inverter is mounted in a vehical and broke from driving vibration. Still works with the new card but doesn't start my welder. It worked fine before as now the welder now power cycles. I have a Ver11.1 board to install and need to update the wiring harness to install charging and true split phase as a bonus but realistically keep the wire schematic the same. Do you think I should Remove the two resistors and install the Capacitor back in its place along with setting dip switches to 5,9,&10 on on the 11.1 or put it on the 10.3c?My only concern if i do that i will have issues with charging? See image 3653 & 3789 are the old card, SEE ADJUST10 & ADJUST11.. Image 3792 is the new or default card. By the way I have two battery banks at 225AH each bank feeding 2/0 cable X2. Also run a plasma cutter time to time on my U-power15K and PJ8K before without a struggle. The plasma tho was 5200 watts on 220. It seems like after the failed they obviously not the same of course but not the cause of the failures. Quote Link to comment Share on other sites More sharing options...

See image 3653 & 3789 are the old card, SEE ADJUST10 & ADJUST11.. Image 3792 is the new or default card FYI that's not a capacitor on the "old" board at "ADJUST10"...it's an SMD resistor installed upside down. A capacitor will not serve much of a function there... The DIP switch's purpose is an adjustable resistance shunt across the current sense transformer (E124-LF-L). The more shunted the output of that transformer, the more power the inverter will produce before declaring an overload condition. And before v11 (where the adjustable resistor shunt is bypassed with a fixed value in charge mode), it would also simultaneously adjust the charge current. 2 Quote Link to comment Share on other sites More sharing options...
