\"JFYJFY JSI Solar Inverter is a Chinese-manufactured brand so it can be expected that it is way cheaper compared to European inverters on the market.  Several factors may affect an inverter\u2019s performance which may result in failures.<\/p>\n

We have put together a list of fault displays and possible action from JFY JSI Solar Inverter’s user manual<\/a><\/strong> for your convenience.<\/p>\n

If any problems arise, the \u201cAlarm\u201d LED on the front panel will be red and the LCD displays the relevant information. Please note that safety measures should be observed to avoid any risk of injury or you may also seek assistance from a qualified electrician.<\/p>\n

E01 Isolation error<\/td>\nCheck the impedance is between PV (+) & PV (-) and the PV-Inverter is earthed. The impedance must be greater than 2M\u03a9<\/td>\n<\/tr>\n
E02 Leak error<\/td>\nThe leakage current is too high.Unplug the inputs from the PV string and check the peripheral AC system.<\/td>\n<\/tr>\n

Please note that during periods of little or no sunlight, the JFY JSI Solar Inverter may continuously start up and shut down. This is due to the insufficient power generated to operate the control circuits but this is not a trouble.<\/h5>\n

Here are some more fault messages that you may see on the JFY JSI front panel display.<\/h4>\n<\/div>

The full details are available in the JFY JSI solar inverter manual\u2019s troubleshooting section<\/a><\/strong>.<\/p>\n

If following the steps above does not fix the issue and your JFY JSI Solar Inverter is still within the warranty period you can contact the equipment installer or supplier. If your inverter is outside the warranty period we suggest that you contact a professional solar power expert. If you\u2019re on the Gold Coast or Brisbane area <\/strong><\/strong><\/strong>contact Gold Coast Power Solutions here<\/strong> <\/a>and we will be in touch to provide you with further assistance.<\/p>\n
