Abstract: A device and method for an integrated photovoltaic power module. A module include a photovoltaic cell, a rechargeable battery, an alternating current electrical port, and a microinverter. The microinverter has a first link at a first voltage coupled to the photovoltaic cell, a second link at a second voltage, and a boost converter converting power between the first link and the second link. The module includes a DC-to-AC power converter exchanging electrical power between the second link and the alternating current electrical port at an AC voltage. The module has a battery voltage converter with a battery port electrically connected to the rechargeable battery and a first link port connected to the first link and converting between a voltage of the rechargeable battery and a voltage of the first link.

Abstract: A temperature-changing package is disclosed that has a compartment for a composition that will either raise or lower the temperature and a cover to protect the composition from accidental initiation. The package may be used to heat or cool a number of products and may be configured with a plurality of packages in a single unit. The package may also have a plurality of composition compartments as well as a number of product compartments.
