Characteristics of “transformerless dual-stage conversion" inverters
Advantages and limitations of "dual-stage" transformerless architecture
Advantages:
Input voltage range extremely wide
Very flat efficiency curves, with performance rather insensitive to operating conditions and input
voltage/output current. The inverter always operates at the optimal voltage level to maximize efficiency
allowed by the stabilizing action of the DC/DC input converters.
It is possible to create multiple independent input
channels with different installation characteristics
(orientation, tild or diferent panels) without compromising
the energy output of the system.
Better yield with multiple MPPT
Note:
Though the cost per kWp of these inverters is theoretically higher than that of single-stage systems, the
higher energy output achieved makes it possible to recover any increased costs in a few years!
