Querobin Posted January 26, 2019 Posted January 26, 2019 The inverter is not working, I tried to supply with dc and it doesn't turn on. I tried to supply with AC and it does turn on. What could be the possible fault? And what would be the solution? Quote
___ Posted January 26, 2019 Posted January 26, 2019 @Jaco de Jongh knows these inverters a bit better. He's not very active here anymore but maybe he'll answer this one Querobin 1 Quote

Please ask for a replacement board that was manufactured after FEB 2018. There is still some of the older boards floating around. Replacing with those will result in a failure in the future again. Good luck. ___, Youda and Querobin 3 Quote

Please see picture and I hope you can help me figure this out. The error is number 10 and 14. Appreciate the hand. Jaco De Jongh 1 Quote
Youda Posted May 27, 2019 Posted May 27, 2019 (edited) "EPO is open" means that the little green socket on the bottom side of the inverter is empty. There should be a green 2 pole plug with no wires in this socket. This plug is basically a jumper. When installed in the office buildings this plug must be removed and instead a Central Stop button for the firefighters goes there. Other error (14) can be ignored, if the inverter is running okay. It works correctly only with FLA batteries. With Lithium, these under-voltage errors are pretty common. To get rid of them one has to lower the low-voltage cut-off value.

Fazil Posted May 28, 2019 Posted May 28, 2019 hi guysh i am commenting on an old post but its Infini Solar 10kw related. 2x in parallel. 1 inverter has Error 60 and the other is OK. I know its got to do with feedback power but struggling to find the cause. Please assist? Quote

Querobin Posted May 30, 2019 Author Posted May 30, 2019 @Jaco de Jongh 3 inverters, infini super 4k to be repair, ordered 3 dc board which we waited for 6 weeks, first inverter was working with the first dc board with supplies of AC, battery and PV, while the 2nd inverter with the 2nd dc board was not successful, the new dc board was destroyed, burnt upon supplying AC from the grid which means (transistor burnt out). 3rd inverter, upon replacing the dc and supplying with AC, there was a spark so we turned off immediately, removed the dc board and tried testing to the first inverter which is working fine and the dc board (3rd) is also working fine. From this actions, could you please help me with your diagnosis if what would be the problem. I really appreciate the help. Thanks, Querobin Quote

I really appreciate the help. The last 2 times my units blew, both the AC and DC boards popped. I guess that is also the case on two of your units. Quote
