OOh Bugger, It looks like I'm gonna have to get a new genset, Inverter and charger as there around 2 1/2 years old.
Ref the noise output my big deisel gen puts out 82db and that is stupid loud although its only used rarely and when I do i warn people within half mile radius.
Ive always found with stuff from china its ok, just dont rely on it for continues service. If you dont like it, you dont have to spout bollocks and rant about it. Just dont buy it
