Beschreibung
Zusammenfassung:	A hybrid solar power supply unit control system comprising a power arbiter unit connectable to a photovoltaic power supply and at least one mains connected variable voltage power supply having a variable voltage control circuit and comprising circuitry to connect the input photovoltaic power supply and variable voltage power supply and combine power from the power supplies for direct current (DC) output, and transition between power supplies based on the available input power from each power supply; and characterised by a power controller configured to measure output current from each power supply and control the variable voltage control circuit to adjust the variable voltage power supply output voltage in accordance with a maximum power point tracking algorithm to cause the photovoltaic power supply to output maximum power for current solar conditions.
