Embodiments include modular wall systems, smart glass controllers and methods for operating such. In one scenario, a modular wall system is provided which includes a frame with a horizontal stringer. The modular wall system also includes first connectors positioned on the horizontal stringer, and a decorative smart glass pane which includes second connectors configured to attach to the first connectors on the horizontal stringer. The second connectors and the first connectors physically attach the decorative smart glass pane to the modular wall system. A power connector is also included. The power connector is configured to receive a direct current (DC) input voltage from a power source. A power inverter converts the DC input voltage to an alternating current (AC) voltage of less than a threshold maximum number of volts. Furthermore, a smart glass surface is included, which is in communication with an output of the inverter.
