The Generac PWRcell 50A Smart Management Module (SMM) model G0070000 manages power usage and prevents overload. A PWRcell system can be augmented with up to eight individual Smart Management Modules. SMMs do not require additional control devices for operation. SMMs function by monitoring inverter power frequency (Hz). When loads demand more power than the inverter can produce, the PWRcell inverter will change frequency, signaling SMMs to shed loads and allow the inverter to recover. The modules can be set to a load priority between 1 to 8 or be set in a lock-out mode for loads that do not need to run in an outage.
