This inverter wires directly
to your generator (wind
turbine, solar panels, etc.),
without other equipment.
After, you plug the grid-tie
inverter directly into a
standard 110vAC or
220vAC wall plug, 50Hz or
60Hz.

Plugging yourself into
parallel with the public
electricity never went so
easy! With this appliance,
when you will produce more
electricity than what you
use, your electric meter will
start spinning backwards.
