An apparatus and method for controlling a DC-to-AC inverter is disclosed. The DC-to-AC inverter may be configured to convert DC power received from an alternative energy source to AC power for supplying an AC grid or load. The inverter may determine whether the power presently supplied by the alternative energy source is less than a predetermined amount of power and, if so, disable an output converter of the inverter. Additionally, the inverter may predict the voltage of a DC bus of the inverter at a future point in time and, if the predicted DC bus voltage is greater than a predetermined maximum DC bus voltage, enable the output converter to transfer energy from the DC bus to the AC grid to reduce the DC bus voltage.
