Page 20: General Comments Regarding Solar Modules
The temperature coefficients on the solar modules data sheet must be observed. More exact values for dimensioning the solar modules can be provided by suitable calculation programs, like the Fronius Solar.configurator (which can be downloaded from http://www.fronius.com). Note! Before connecting up the solar modules, check that the voltage for the solar mod- ules specified by the manufacturer corresponds to the actual measured voltage. -
Page 21: Do Not Ground The Poles Of The Solar Modules
Note! When designing cable cross-sections, take local regulations into account. Connection conditions: Carefully clean the oxide layer from the bare end of the cable by scraping it, e.g. with a knife IMPORTANT! Do not use brushes, files or emery paper, as the aluminium particles get trapped and can be transferred to other conductors. -
