Systems and methods for use with renewable energy resources that provide power to an energy power grid or to one or more motor loads. A control system along with an energy storage/combiner block and a DC/AC inverter is used to condition DC power received from renewable energy sources. The control system receives current and voltage outputs from the inverter along with values indicating current and voltage outputs directly from the renewable energy sources. These are then used to estimate and control motor speed when the system is in the off-grid mode. In addition, the control system uses these inputs to provide the gate pulses that are used to control the three phase AC output power from the inverter.
