Many thanks, will do and report back! Thanks again!

Ok, I magaed to get all working now without tripping the ELD. Now when mains goes away the inverter makes a funny ZZZZZ noise and after approx. 10 seconds battery shutsdown by it self. Pylotech`s do thatapparently when charge voltage too high. I set bulk charge down to 54V but it still happens. Tried on PYL and on USE settings. Any ideas guys? please help.

Hi All/Coulomb I am experiencing a niggling issue with a Kodak OG5.48. All was running fine after install with Pylontech UP5000 battery. Then last week I addedsome 545 Canadian solar panels in series, 8 to be exact. I then switch output priority to SBU. Soon as it starts up the Inverter trips earthleakage and restarts and give F08 error. If running it from utility and solar it runs fine, if running it from utility and battery it runs fine. It seems when adding solar it start with issues. there is surge protection on the solar and I measured the incoming voltage is 403 Volts. According to manual specs it should be able to run up to 450 Volts. I also set the charging currents down to 20A but issue persists. Please help as now my solar is just sitting there and doing nothing. Firmware U1-47.00, U2-2.83
