The INVOLAR Micro-Inverter System Instruction
The INVOLAR Micro-Inverter System
The three key elements of an INVOLAR Micro-Inverter System are:

The INVOLAR Micro-Inverter

The INVOLAR eLog communication gateway

The INVOLAR SDEDAS/SELITE web-based monitoring and analysis

PV module
The INVOLAR Micro-Inverter maximizes energy production from the PV
array. Each INVOLAR MAC500 is connected to two PV modules. (See
Figure 4-1 this figure should be updated with new connection diagram)
This unique configuration means that a Maximum Peak Power Point
Tracker (MPPT) controls each PV module. The INVOLAR MAC500 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.

NOTE
The INVOLAR eLog communication gateway, the INVOLAR LCF(Line
Communication Filter) and the INVOLAR SEDAS/SELITE(Solar Energy
Data Acquisition System) are optional elements, before installing
these elements, read all instruction and cautionary marking in the
related user manual.
