Abstract

A solar system for a motor vehicle, which is provided with a solar generator and a DC/DC converter unit, the solar system being switchable for supplying a power consuming device in the motor vehicle or for recharging of the motor vehicle battery. The DC/DC converter unit is made with two poles on the output side and functionally comprises a first and a second DC/DC converter which are respectively optimized with respect to the supply function of the power consuming device and the recharging function, there being a changeover unit which acquires the voltage at the output of the DC/DC converter unit and switches the output depending on the acquired voltage to either the first DC/DC converter or the second DC/DC converter.

Dependent claims

A solar system for a motor vehicle with a motor vehicle roof and a motor vehicle interior, the solar system comprising:

a solar generator, and
a DC/DC converter unit,
wherein the solar system switchably supplies a power consuming device in the motor vehicle and recharges a motor vehicle battery in the motor vehicle,
wherein the DC/DC converter unit comprises a first and a second DC/DC converter,
the first DC/DC converter being optimized with respect to a supply function of the power consuming device and second DC/DC converter being optimized with respect to a recharging function of the power consuming device, and
wherein a changeover unit is connected to an output of the DC/DC converter unit to acquire a voltage therefrom, and wherein the changeover unit is responsive to the acquired voltage for between the first and the second DC/DC converters.
