General Information

Operational Modes Overview

Generac PWRcell offers several operational modes for
various installation configurations,
applications. Connected REbus devices work together to
manage the distribution of power based on the selected
operational mode.

Never sell power to grid
Grid Tie
In Grid Tie mode, the Generac PWRcell Inverter
functions as a conventional grid-tied inverter system. The
system powers local loads and when generation exceeds
load demand, excess power is exported to the utility for
net metering and other credits.
NOTE: Grid Tie is intended for use with systems that do
not include a Generac PWRcell Battery. For systems
where a Generac PWRcell Battery will be connected at a
later date, operate in Grid Tie mode until the battery is
installed.

Clean Backup

NOTE: Grid power is not used to charge batteries in this
mode.
See Figure 2-6. In Clean Backup mode, the Generac
PWRcell Inverter prioritizes keeping the Generac
PWRcell Battery charged and ready for a grid interruption
using solar power only. If the battery is not fully charged,
the inverter uses all available solar power to charge the
battery.
See Figure 2-7. When the battery is fully charged, solar
power will flow to local loads and the grid.
