Enecsys announces cost-saving, solar PV Duo

CAMBRIDGE, UK: Enecsys Ltd, a solar photovoltaic (PV) micro-inverter company, has announced the Enecsys Duo micro-inverter.

This 360-Watt addition to the Enecsys micro-inverter family is the world's highest power density micro-inverter with dimensions of 262 x 160 x 35mm. Designated the SMI-D360W-72, it is designed to reduce system costs whilst supporting fully independent power point tracking of two connected photovoltaic modules. 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. Solar PV systems using the Enecsys Duo will have comparable capital costs to those using string inverters but will deliver 5 percent to 20 percent more energy.

The degree of improvement in energy harvest depends on the installation configuration and the operating environment. When adopting the Enecsys micro-inverter solar PV architecture, systems do not suffer from dramatic reductions in output when modules are mismatched or when one PV module, or part of a module, suffers from lower output due to shading caused by trees, chimneys or debris on its surface. These are some of the most significant problems in conventional systems employing string inverters.

The Enecsys Duo micro-inverter has 95 percent peak efficiency and 93 percent Euro efficiency. The Enecsys Duo micro-inverter is based on the same patented technology employed in other Enecsys micro-inverters and maintains full performance from -40 degrees C to +85 degrees C, an important consideration in real-world operating conditions on residential and commercial rooftops.

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.
