Morningstar's Relay Driver is a logic module which provides high level system control functions such as high/low voltage alarms, load control and generator start. The product controls four independent relay driver outputs by reading digital data inputs from Morningstar's TriStar controller or by reading battery voltage when used in systems with other controllers.

When connected to a Morningstar TriStar controller the relay driver module can control relays based on battery voltage, charge / load current, battery temperature, TriStar heat sink temperature, PWM duty cycle, PV load voltage and any other TriStar alarms and faults. When used in systems with other controllers the Morningstar relay module can control relays based on battery voltage, relay driver temperature and input voltages from other sources.
