NotMario Posted October 19, 2022 Share Posted October 19, 2022 Sometimes simple is best... Is it dirty/dusty? Are you certain about your power draw? (You're not actually overloading it...) Systems tend to gain more load over time... Sounds like yours doesn't have the verbal alarm like mine... when the alarm goes off, you don't get a voice telling you what it's alarming about?

dickson Posted October 19, 2022 Share Posted October 19, 2022 Power jack 12000. Need help Powerjack only have parts for the new AMG 12000 watts inverter . All older Powerjack are very difficult to repair if need replacing the old control board with rev 11.3 control board . Quote Link to comment Share on other sites More sharing options...
Lener Posted February 10 Share Posted February 10 My 12000w PJ often tripping the breaker when switching to charging mode, Regardless which breaker . Wondering if the charging board is bad for pulling too much current like a motor causing an inrush surge .even with the single dedicated 20 amps breaker. Would I need some type of soft start inrush current device, a choke or resistor…….. this PJ machine has been nothing but a challenge. any advice! Thanks.

Word of wisdom: the use of charge / AC input on any PJ inverter is almost guaranteed to result in inverter failure--as any venerable PJ customer will tell you. What you're seeing is the result of very poor firmware in the control board MCU. I'm surprised it doesn't blow up every single time it transits. Replacing boards/parts will not solve the issue. 1 Quote Link to comment Share on other sites More sharing options...

I came home this evening the breaker tripped and was tripped earlier this morning before I left , this has become more frequent now…. Very disappointing Quote Link to comment Share on other sites More sharing options...

"As long as it sells, there's no reason to change it." As far as I know, the firmware in the MCU hasn't changed ever since they switched to the Microchip MCU.
