RESIDENTIAL SYSTEM DESIGN
Optimal inverter sizing for PV installations with The LynxPlanner layout tool
Establishing the correct ratio between PV module power capacity and inverter power capacity is one of the key criteria for optimised PV power plant design. Under-sizing the inverter can lead to frequent “derating” of the PV power plant where, for example, the inverter moves the operating point away from MPP. This results in less PV powerplant yield than is actually possible. On the other hand, over-sizing the inverter leads to unnecessary costs.
The LynxPlanner layout tool
Using our layout tool, the LynxPlanner, it’s simple to design your system. You can draw complex roof areas, and by adding objects with potential shading you can get a more accurate system suggestion designed for real-life situations. Please see link below.
Understanding the core criteria
During ratio selection, the following factors need to be taken into consideration:
• Irradiation
• Module temperature
• Orientation of the PV panel
• Tilt degree of the PV panel
• Geographical location
Multiple individually regulated MPP trackers in the TLX range
Now it’s possible to design systems with different angles, orientation or different numbers of modules per string, using just one inverter. You can realise any system from 1.5 kW to 17 kWp.
