Abstract
Various examples are directed to a solar power electrolyzer system comprising a first electrolyzer stack, a second electrolyzer stack, a first converter and a first converter controller. The first electrolyzer stack may be electrically coupled in series with a photovoltaic array. The first converter may be electrically coupled in series with the first electrolyzer stack and electrically coupled in series with the photovoltaic array. The second electrolyzer stack electrically may be coupled at an output of the first converter. The first converter controller may be configured to control a current gain of the first converter.

A solar-powered electrolyzer system comprising:
- a first electrolyzer stack electrically coupled in series with a photovoltaic array;
- a first converter electrically coupled in series with the first electrolyzer stack and electrically coupled in series with the photovoltaic array;
- a first converter controller configured to control a current gain of the first converter;
- and
- a second electrolyzer stack electrically coupled at an output of the first converter.
A method of operating a solar-powered electrolyzer system, the electrolyzer system comprising a first electrolyzer stack electrically coupled in series with a photovoltaic array;
- a first converter electrically coupled in series with the first electrolyzer stack and electrically coupled in series with the photovoltaic array;
- a first converter controller configured to control a current gain of the first converter;
- and a second electrolyzer stack electrically coupled at an output of the first converter, the method, comprising:
- determining, by the first converter controller, that hydrogen production for the electrolyzer system has decreased by more than a hydrogen threshold amount over a first time period;
- determining, by the first converter controller, that a current at the first electrolyzer stack has increased by more than a first current threshold over the first time period;
- and
- increasing, by the first converter controller, the current gain of the first converter.
A solar-powered electrolyzer system comprising:
- a first electrolyzer stack electrically coupled in series with a photovoltaic array;
- a first converter electrically coupled in series with the first electrolyzer stack and electrically coupled in series with the photovoltaic array;
- a second electrolyzer stack electrically coupled at an output of the first converter;
- and
- means for controlling a current gain of the first converter.
