[RE-wrenches] Power Factor and Grid Tied PV

[Darryl Thayer]

I recently spoke with an inverter manufacture and I left with the following opinion.  Normally the inverter takes the unity power factor load and leaves the reactive load.  making the power factor worse.  However the power factor could be corrected by the inverter, However this would add cost to the inverter and would not appear to have value to the solar industry.  There are variable reactance devices existing that can correct power factor, is there need for another device?
