A genset includes a generator configured to generate a power signal having a first voltage. A controller is configured to monitor and control at least one operational parameter of the generator. A buss potential isolation module is configured to receive the power signal having the first voltage from the generator, reduce the first voltage to output a second voltage, and communicate the power signal having the second voltage to the controller. The second voltage is suitable for communicating to the controller which can include electronic circuitry configured to meet an NEC Class 2 circuit requirement. The first voltage can be at least 120 volts, and the second voltage can be less than 24 volts.
