If you have a central solar system. From this I mean an off grid solar system with large solar inverters such as an Outback 4040, 4080 or similar systems. For these type of systems you will require a DNA “Line Filter”. A line filter can carry a full load of the required current for example, 100 amps of full load. All other filters on the market today are what are referred to as Parallel or Parasitic type filters. These type of filters do not carry a full load of current and work by sitting on the wires and diverts the DE to Neutral or Ground.
