Hi Gerhard, thanks for the response, I have not removed the transformer,it's disconnected from the circuit though and I have not tested the primary or secondary windings etc, I only tested the live and neutral cable that is connected to the transformer and it tested almost 0 ohms, I will remove it out and see as you are suggesting, I heard it's quite rare for it to be the problem, thanks for the feedback ,🙏

Hi Muratech, unfortunately I did not find any solution yet, however I tested further and noticed when I tested the Toroidal transformer through continuity test that there is no resistance, so when it goes to battery mode i get the error code, im struggling to find a replacement transformer, but if i get a solution I will give you an update.

Hi, I have a Kool Energy 1.5kw 24v inverter working on 2x 12v 100ah gel batteries in series. The inverter was not in use for about 5 months and when it was turned on some of the mosfet transistors popped. I have taken the board in for repairs to a local electronic repairer and he replaced all the transistors(MT06N008A) with a substitute part transistor(FTP08N06A). When I switch the inverter on it runs on the mains(220v), but the moment the mains goes off and it goes into battery mode the inverter displays Error code E02 and switches off shortly after. Error code 02= "Output short circuit" according to the manual. On visual inspecting the board I cannot see other components with clear damage. Is the replacement transistor adequate for a substitution? Battery terminals and connections are all the same as it came from the factory. I will greatly appreciate any input, Regards Helgard
