Topology 1-Phase string inverters
Transformerless Technology Minimizing losses and increasing conversion efficiency.
Other adventages of “Dual Stage” topology:
• The inverter always operates in maximal efficiency region
• Extrem wide input voltage range combined with flat efficiency curve
• Array can be split in 2 independent subarrays each with stand-alone maximum power point
tracking.
