Patent ID: 8080972

Claim:
A system, comprising: a cylindrically-tapered housing having a base proximate a lower end and a handle proximate an upper end; a battery supported on the base and disposed within the cylindrical housing so that a first air space is defined between an outer surface of the battery and an inner surface of the cylindrical housing; a charge controller disposed within the cylindrically-tapered housing above the battery so that a second air space is defined between an outer surface of the charge controller and the inner surface of the cylindrically-tapered housing; an inverter disposed within the cylindrically-tapered housing above the battery so that a third air space is defined between an outer surface of the inverter and the inner surface of the cylindrically-tapered housing; and a chimney venting system for cooling said system, said chimney venting system configured to draw a supply of ambient air along an airflow path defined at least partially by at least one lower opening near said base, and the first air space proximate the battery, and the second air space proximate the charge controller, and the third air space proximate the inverter, and at least one upper opening near said handle.
