arrays can be installed with different positions, facing different directions and with different string lengths; each
array is controlled by an MPPT control circuit.
The high efficiency and extra large heat dissipation system enables operation at maximum power over a
broad range of ambient temperatures. Two independent Digital Signal Processors (DSP) and one central
microprocessor control the inverter; and therefore, two independent computers control the grid connection in
full compliance with safety standards and regulations.
The Inverter operating system (program) communicates with all of the sub-systems within the inverter performing
necessary data processing, calculations to guarantee optimal performance levels of the system and high-
power harvesting in all installation and load conditions, while maintaining full compliance with prevailing safety
directives, laws and regulations.
