Solar Inverters for grid connection and have been developed in order to minimize cost, better performance and extreme simplicity of construction, operation and maintenance. Applications: residential installations, industrial installations, big photovoltaic plants, isolated installations, etc. Multi-megawatt solutions customized to each project and string boxes to maximize the solar PV systems.
Gozuk photovoltaic inverters developed from its experienced designing and manufacturing industrial, robust, reliable, secure and high efficiency power electronics systems. The PV Inverter turns the DC mains coming from a solar PV field into a stabilized AC voltage power output. The central inverter works in grid connected mode, injecting the produced power.

When you hear about the suitability of a particular inverter technology for a particular project, it comes from the perspective of this hard-earned experience. To the best of my knowledge, no peer reviewed paper has demonstrated a performance advantage for micro inverters in commercial applications -- let alone an LCOE advantage (taking into account the considerable difference in price points for string or central inverters compared to micro inverters). Perhaps you can show me otherwise?
I have seen recent work presented by NREL which demonstrates the performance advantage of the micro-inverter architecture for shaded conditions. This analysis appears to be well done and we appreciate the rigorous approach. Again, though, I wonder if the performance advantage (3.7% in the case of light shading) can overcome the price premium for the microinverter system.
So we tend to think that other factors are at work in the inverter market. The perceived ease of use of micro inverters shouldn't be discounted, for example. In the fast-growing North American market there are many new entrants so this factor is important. We are excited to be launching our SB 240 micro inverter system this year and look forward to serving the needs of these new entrants to the market and those companies who have built their businesses around the characteristics of microinverter technology. We have a few tricks up our sleeves and are optimistic about our chances to compete in this segment. After all, our track record is pretty good.
However our firm opinion is that over time even these new entrants might seek ways to improve returns and move towards more established technologies with proven gains in LCOE or ROI.
BTW, this might also explain your comment about "integrators turning to micro inverters for large-scale projects." I wonder if you can point to (for example) any of the Top 15 commercial systems integrators who are using microinverter technology for large-scale projects? If one supposes that these large, sophisticated integrators might be using global best practices, then it might be important to note that these companies rely on central inverters or decentralized string inverter architectures to deliver leading returns to PV investors.
