About PWRcell Inverters
The PWRcell inverter connects to PV Link™ optimizers
and PWRcell batteries to form the PWRcell system for
grid-interactive solar-plus-storage.
Upon the loss of grid power, PWRcell inverters
disconnect from the grid and provide AC power to
support protected loads when configured to do so.
All PWRcell products use the REbus™ 380 VDC
nanogrid to connect to each other. The REbus nanogrid
automates the flow of power to enable plug-and-play
setup and operation of PWRcell equipment. For more
information about REbus, visit www.generac.com.
In Figure 2-3 PWRcell inverter (E) is directly connected
to PV Link optimizers (B) and PWRcell battery (C) on DC
(REbus) lines (D). To the right of the inverter are AC
lines: 120/240 VAC for grid and home loads (G), and
protected loads (H) support.
