Hi Drake,
I think you can put a power diode in parallel to the gt inverter that can
conduct that inductive current if you need to. However, I think BoB is
correct, there should just be induction of the wiring itself for most
grid-tied inverter. The relay engineer recommended this diode for a DC
Since grid-tie inverters sell back with a power factor of 1, the load
~should~ be entirely resistive and
not inductive or capacitive so a appropriately rated relay contacts
~should~ be fine.
Except maybe if the inverter is designed to supply VARs like the last
Solar-Pro magazine talks about.
Hello Wrenches,
Do the relays that break the current from the direct grid tie
inverters, in AC coupled systems, need to be motor rated or can they
simply be rated for the amperage of the inverter output? How
inductive is the current between the two inverter systems? Will the
current tend to j
