Solar generator 9 DC 12 L3 u PE Dc i a N DC actuator HERIC inverter i L1 L2 L3 PE N 1 3 Integration in solar system Solar generator configuration The technical data of the selected solar generator must be within the Solar Inverter s specifications see Technical Data Incorrect dimensioning can lead to reductions in the yield and to destruction of the device The Sundim design program from Sunways can be used for this purpose Sunways Sundim can be found on the enclosed CD ROM or on our website at www sunways de Be sure to take the following points into account before planning your system Watch the celestial alignment of the modules In Central Europe a maximum yield is achieved with a module tilt of 30 to the horizontal and direct south orientation of the solar generator field The output of the cells decreases as the module temperature increases Install your solar genera tor with sufficient ventilation from behind Check your solar generator approx every three years for soiling This occurs especially on the lower edge of the modules and forms a veil that cannot be washed off even by heavy rain Reduced yield can be prevented by cleaning with a wet cloth or a brush Avoid shading of individual modules or solar cells in your system This can lead to major reductions in yield 1 Product Descr
