I was on site yesterday. Redid the wiring. Swopped the inverters interms of who is boss and also checked the connections of the cards to inverters. In other words all possible hardware issues except replacing the cards. And the heat issue with the fans thats an really good idea cause it does get.hot there... Very hot so i hope its sorted now but lets see

Coulomb thank you very much. Much appreciated. I wont be at site to spray it. But when i can is that site is near Phalaborwa in Limpopo which is very hot... So temp can have an influence although i also doubt as lately its happened around 5am. When it gets to the stage where it constantly happens in other words not even an reset works. Cause then my client needs to by pass thr system where the inverters have an opertunity to cool down. So I think its is part of the problem but not the source of the problem

Hi All. I want some advice. I have a system with 2x 5kw Axpert inverters paralled. System has been going good for about 1yr no issues. Now it cuts out on error 72 which is current sharing issue. Problem is it is not consistent. And can trip now continuously. Other times it can work a week no problems other times just a trip and restart. What can be wrong? Some say parallel card, others say load sharing cables, others say synchronisation issues. Cable work is fine. And what makes this hard that it is inconsistent but yet often that it is an fault
