Voltage prioritization of solar loads

摘要

Solar electric energy is optimally used by varying one or more connected loads to achieve a maximum output power voltage. Entire appliances may be switched on or off, or modulated, as in the case for example of a heat pump compressor circuit or electric water heater. Variations of this theme are used to prioritize appliance usage for overall improved convenience and efficiency. Solar electric appliances such as refrigerators, freezers, air dryers and water pumps are described. This and other electric sources may be used to power electric garden tools. Electric distribution tools and methods are described as well as electric garden tillers with features such as semi-control and smooth operation.

主权项

1. A solar electric distribution system, comprising:
one or more solar panels that provide a solar panel supplied voltage having an optimum voltage output, an energy storage unit charger and a variable appliance loader that provides pulsing direct current power to an appliance from the solar panel supplied voltage based on priority level of the appliance, connected in parallel, wherein the variable appliance loader provides pulsing direct current power to the appliance at a lower solar panel supplied voltage when the appliance is higher priority and provides pulsing direct current power to the appliance at a higher solar panel supplied voltage when the appliance is lower priority.
