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. This

capability is referred to as islanding.

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).
