You want to install solar panels for your business. How can you choose the best microinverters?

First, was the decision to use microinverters a well-thought-out process with comparisons to other technologies, or do you just want to use micros for the sake of using them? It matters. But to get to the answer, use the same process as you would when buying anything. Use a reputable product/installer, make sure the design is good, and RTFM.

Microinverters make more economical sense for residential installations compared to large commercial systems. Yet, the string inverters are still the popular option as they are more budget friendly. Most of the time, solar designer will try, as much as possible, to avoid shading effect during initial design. Nothing much can be changed with the roof orientation. So unless somehow, some parts of the solar system are critically oriented to not receive direct sun light, then there is no solid reason to use microinverters compared to string inverters.

Los microinversores nos permiten ahorrar espacio en las instalaciones eléctricas residenciales con respecto a los inversores convencionales. Su operación es práctica y adicionalmente permiten monitorear el rendimiento de uno o un peque?o grupo de paneles solares. Son la solución para proyectos solares fotovoltaicos residenciales de 1 o 2 kWp.

When procuring and installing microinverters for solar business installations, apart from the technical details like type, etc, one should also keep in mind the requirements of the grid. Finally, the solar plant will be connected to the grid for selling the produce. One should study how these inverters interact with the grid during operation and whether they can provide LVRT (Low Voltage Ride Through) Capability. One can also see the future business value of the inverters, like the capability to provide ancillary services to the grid, like reactive power support, synthetic inter, etc.

Lo veo quizás interesante para peque?as instalaciones privadas, pero no para grandes campos, ahí un inversor normal de grupo, a la larga, creo que conviene en cuanto a eficiencia.
