I have a Pheonix multiplus 24/3000/70 for an off-grid system to supply my house with a generator on auto-start . I have had the same set-up for some years. I now have a problem with the 16A thermal switch popping out after some minutes when the genny fires up due to an additional load e.g. washing machine. Is this simply a case of the switch becoming faulty? I don´t understand the reasons for the switch popping in the first place since neither the overload or temperature warning lights come on.
Thanks for any advice.
