Does anyone think we should have a sub forum for posting troublesome components ? Manufacturers must have product recalls ? and we must have accessories that don't play ball ?

Maybe rather than banning some users for a relatively minor offence or first time offence, there should be an area where they can post but not interact with the rest of the forum whilst they serve their time!!
Guys,
As we know, for switches/cables/isolators etc, you need to multiply your Voc values by 1.15 and Isc values by 1.25 to calculate the relevant max values for suitable protection. However, does this apply to MPPT or Max DC voltage/current input values on inverters? Any thoughts?
Thanks
Andy
