The Generac® Smart Management Module (SMM) is a stand-alone wireless unit. It can control one 240VAC circuit/device up to 50 Amps. It simply watches incoming voltage and frequency. With correct voltage and frequency, the SMM will allow the circuit/device to operate. If voltage and frequency fall to an unacceptable level, the SMM will shut down the connected circuit/device. The SMM is typically used for larger load items connected to the generator. In addition to the Load Shed Module in the transfer switch, the SMM helps protect the generator from an overload condition. With an outdoor-rated enclosure, the SMM allows a lot of flexibility for installation. It can be mounted and installed anywhere between the breaker and the item being powered.
