Frequently asked questions to the Technical Committee

The Technical Commission under direction of Joris Melkert received the past months a lot of questions and the first designs are judged. It strikes the committee that a lot of questions were about the maximum voltage in the electrical system (rule 7.4 of the technical regulations) and about the positive grounding of the solar cells of The Sun Factory.

In the technical regulations is noted that the maximum allowed voltage is 52 V DC or AC RMS. After several questions of participant on this point the Technical Committee decided in Note 2 to the regulations that the voltage in an open circuit is allowed to be higher. But, as soon as the electrical system is switched on the voltage has to be 52 V or below. In Note 2 the Technical Commission also wrote how teams of Challenge classes can use the positive grounding of the sponsored solar panels.
