Hi All

My xantrex 4kW inverter is humming/buzzing!

it has always made a little hum when inverting but this noise has suddenly got much louder under load (2.5 Amps) with detctable vibration when i touched the casing  Huh. the noise subsides to normal when no demand is on the unit.

Anybody any experience of this or any ideas?

Anyone know of a good service engineer for these units?

Many thanks

Sounds like the cooling fan's bearings are going.

Hi Just

The fan normally kicks in when charging and this noise is not the fan.

any other ideas?
