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.

Power supply system for an electrochemical stack

A DC power output system may achieve variable output power by paring a variable inverter with a rectifier. DC power output system may implement DC power adjustment at the output of the rectifier least in part by varying the power supplied from the variable inverter to the rectifier.

Variable inverter based power control

A method of measuring vapor flux density including directing a light beam through a vapor flux to a pixel array sensor and using the pixel array sensor to measure attenuation of the light beam.

Method of measuring vapor flux density

A flux monitor system includes a light source and a sensor.

Flux monitor

A particle detector for evaporation flux is disclosed. The particle detector includes a light source and at least one reflective surface.
