6 Owner’s Manual for Generac PWRcell Inverter
General Information
System Modes Overview
Generac PWRcell offers several system modes for various installation configurations, markets, and applications.
Connected REbus devices work together to manage the distribution of power based on the selected system mode.
Some modes interact with PWRcell batteries to store power and/or balance production and consumption.
See Table 2-1 and Table 2-2 for an overview of available system modes.
Grid Tie
In Grid Tie mode, the 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 PWRcell battery. For systems where a
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 2-5. In Clean Backup mode, the inverter
prioritizes keeping the 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 2-6. When the battery is fully charged, solar
power will flow to local loads and the grid.
