4.1 The INVOLAR Micro-Inverter System
The three key elements of an INVOLAR Micro-Inverter System are:
The INVOLAR Micro-Inverter
The INVOLAR ETU communication gateway
The INVOLAR SDEDAS web-based monitoring and analysis
PV module
The INVOLAR Micro-Inverter maximizes energy production from the PV array. Each
INVOLAR Micro-Inverter is individually connected to one PV module in the array. (See
Figure 4-1).
This unique configuration means that a Maximum Peak Power Point Tracker (MPPT)
controls each PV module. The INVOLAR Micro-Inverter ensures top performance for
its associated PV module although individual PV modules in the array may be
affected by shading, soiling, orientation, or PV module aging. This insures that the
maximum power available from each PV module with a consequent up to 25% more
energy production. The distributed nature of the INVOLAR Micro-Inverter System
insures that there is no single point of system failure in the PV system.
