The design aims to reduce system costs while supporting a fully independent power point tracking of two connected modules as the company states. The DC power generated by the two modules is converted into a single, grid-compliant AC output in the Enecsys Duo. System layout and planning is simplified and installation time and costs are reduced because only half the number of micro inverters is needed for each system according to Enecsys.
Solar PV systems using the Enecsys Duo will apparently have comparable capital costs to those using string inverters but will deliver five to 20 percent more energy. The degree of improvement in energy harvest depends on the installation configuration and the operating environment.
The Enecsys Duo micro inverter is based on the same patented technology employed in other Enecsys micro inverters and maintains full performance from minus 40 to 85 degrees Celcius, an important consideration in real-world operating conditions on residential and commercial rooftops as Enecsys says. Solar modules connected to the Enecsys Duo do not need to be matched or be located on the same plane. They can be oriented in different directions to maximize usable roof space without impacting overall system performance.
