[QUOTE="binky, post: 551623, member: 490"] I would get that fully investigated / update all the boards. At 15 years old, there's a chance the inverter is just at end of life. A new unit will be more efficient than what you currently have anyway, and pay for itself in a few years. Out of interest, if you turn off the other circuits when tripping happens, does it keep working? Generally speaking, a fault with the DC side should show as a fault code in the inverter screen, usually 'riso' which would indicate earth leakage around the panels. I'm not familiar with your unit, so you may not have a screen at all, but there's usually some form of visual fault indication. [/QUOTE]
