I am looking to add a 120vac Inverter to an existing 12vdc off grid radio power supply. My concern is that most inverters introduce interference to the broadcast signal.
>From what I understand, if the GEC is connected at the battery bank (-) the interference is less. Then the GEC needs to be sized for the battery cable size. For example if I use a 2000w inverter that would be a 250adc breaker, 4/0 battery cables and a #2 copper GEC. But then what about the GFDI for the roof top PV. The radio tower can not be with out a reference to ground. The tower / building is used as a dwelling / office for three seasons and for search and rescue communication year round. Not enough solar access for a ground / pole mount array
