Abstract
A system includes a power supply for an electrochemical stack. The system may support operation in at least two modes: a first where power for the electrochemical stack originates from a renewable energy (e.g., an on-site) power source, and a second mode where power for the electrochemical stack is supplied at least in part from a power grid interconnection. A source power converter may adjust its operating voltage to select between prioritizing power from the on-site source and/or drawing power from the electrochemical stack at least in part from the power grid.
