For orientation in the selection of photovoltaic modules, please refer to the power values given in watts (W), sometimes also indicated as Watt Peak (Wp), as well as the voltage values in volts (V). The solar module must not exceed the output power of the inverter (AC power) by more than 30%. In addition, the open circuit voltage (Uoc \/ Voc) of the module must be within the voltage range of the inverter and must not exceed 95 % of the maximum voltage of the inverter. If the solar modules provide a higher current than the inverter puts out, the inverter automatically downregulates the electric current. Automatic regulation does not cause any damage to the device.<\/p>\n

In practical terms, this means that an INV500-90 inverter can be connected to photovoltaic modules with up to 700 watts power and an open circuit voltage of 84 volts. The inverter type INV315-50 can be connected to solar modules with up to 400 watts. Also, with the INV315-50, the maximum input voltage of 50 volts must not be exceeded. This means that PV modules with a maximum open circuit voltage of 44 volts should be used to prevent damage to the inverter.<\/p>\n

As soon as the power delivered by the solar module exceeds the absorption limit of the inverter, it will automatically switch to maximum and leave the additional power settings unchanged. In any case, it is preferable to choose a photovoltaic module exceeding the inverter in maximum power, because solar modules are rarely optimally aligned. On balconies, in particular, they usually yield a reduced power output. The optimal orientation for a solar module is to the south with an inclination of 30\u00b0. Even with optimal orientation, the maximum power values of a PV module are rarely achieved, as factors such as clouds or shading also reduce the power yield.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

There are several ways to connect solar modules and inverters:<\/p>\n

    \n
  1. Series connection
    \nIn this type of connection, two or more PV modules are connected to each other by connecting the negative cable of one module to the positive cable of the next module. The end of the first and the last module are connected to the inverter. Next, the inverter is connected to the AC line, which is in turn connected to the power grid.
    \nPlease note that powers and voltages add up to each other when connected in series. If the open circuit voltage of the modules connected in series is higher than the maximum input voltage, the inverter will take irreversible damage!<\/li>\n
  2. Parallel Connection
    \nThe PV modules can be connected via a y-cable in a minus-to-minus and plus-to-plus pattern. The positive and negative cables of the Y string are connected to the corresponding connective pieces of the inverter.<\/li>\n<\/ol>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

    The flashing code indicates the current operating status of the inverter. The signals provide information about the current feed-in power of the inverter as well as a possible malfunction. The meaning of the individual flashing signals can be found in the operating manual of the respective inverter on page 7.<\/p>\n
