Generac's Smart Power Management System is designed to optimize the performance of a standby generator or PWRcell energy storage system (ESS). The system can consist of up to eight individual Smart Management Modules (SMM). Unlike other load management systems that depend on another control device, the SMM's are self-aware and operate autonomously.

Frequency is the true measure of system performance, and does not need to factor in increased ambient temperatures, elevation changes, or generator fuel type. The SMM monitors the frequency (Hz) of the power being produced by Generac's standby generators or PWRcell ESS. If frequency falls below a certain threshold of a correctly sized system, the SMM will automatically shed the managed loads to allow the system to recover.

The modules can be set to a load priority between 1-8, or be set in a lock-out only mode for loads that do not need to run in an outage. This reduces the minimum size of system required for a more cost-effective solution.

• It is recommended to size the generator or PWRcell ESS with appropriate excess capacity to allow starting of the largest managed loads (i.e. loads with highest starting currents). Each managed load of the SACM and SMM must be assigned a unique priority setting, so no two managed loads attempt to start simultaneously. See owner's manual for more information.
