111Goodday everybody I have two of these remote control panels that I want to upgrade the firmware. One has version U3 01 03 the other has U3 01 06. What flashing program and what firmware would be good to1use. It is with an array of 3 axpert 5kw invertors in parralel.

Good choice.. I am busy with an invertor for about a week now. I got for free so....😭 I got 4 of the same type.. badly damaged. No.1 is running after a week. Yes 5 days of about 16 hours each. No.2 is not so lucky yet and already at day4.🙈

Mmmmm... maybe not worth it. Try to bury it and if that doesn't work, just trough it away.

I am in pretoria....will that help?

Hi. I have a steca 5kw. Axpert based. I have fixed burned mosfets and igbt, I have also replaced the voltage regulator-12v and all the elwctrolytic caps in the power supply. The invertor starts up without error 09 now.😁 But when the invertor side begins to run , it draws an over current. My power supply connected to the battery terminals limits the current drawn to 2amps. And then the setup trip and restarts. The Q32 igbt keeps on failing. And I have rwplaced it about 12 times in a row now. I can't find any other problems on thw board as for this bliwibg Q32 problem. Does anyone have a idea why this igbt keeps blowing?
