Hi our Multiplus 12/3000 has developed a fault , when trying to power up the Inverter on led flashes irregularily for a few seconds and there is a noise like a light rattling at the top end of the unit and then the overload goes on and nothing else. i have checked the battery voltage in 13.7 and there is no voltage drop on both pos and neg even went straight to the batterries with jump leads . disconnected the RJ45 for the remote also , no difference.
Has anyone seen this before ?
I have spoken to Energy Solutions in the UK and can send it for repair but if i can save al the shipping it would be better.
Regards
Gordon
