During the inverter sizing you need to take into account the different configuration limits, which should be considered when sizing the solar power inverter (Data from the inverter and solar panel data sheets). During the sizing, the temperature coefficient is an important factor. 1. Solar panel temperature coefficient of Voc/ Isc:
The design of solar panel strings needs to satisfy two conditions simultaneously: The maximum open-circuit voltage of the series-connected photovoltaic modules should be lower than the inverter''s maximum input voltage. The MPPT voltage of the series-connected photovoltaic modules should fall within the inverter''s MPPT voltage range.
The number of solar PV panels in each string must be at least 4 modules. The PV array must not exceed one string. This step is not required for the inverter MPPT with only one string. The PV generator (PV array) consists of one string, which is connected to the three-phase 5KW inverter.
The KACO single-MPPT string inverter range offers a much easier and more flexible design through the use of DC combiners which is crucial when optimizing your PV module layout. The entire solar industry has been eagerly following, and in some cases frantically playing catch-up with the trend of ever-increasing solar module power ratings.
