In recent times, we have seen an increase in our customers interest micro pv inverter . Micro-inverter is similar because they are the AC power generated by the solar module can be used in the home, and fed into the public grid solar generated direct current of conventional inverters.
Many people believe that micro-inverter is new, cutting-edge technology, they are not, micro-inverter technology can be traced back to the 1980s. Micro-inverter manufacturers have agreed to go into business, and then they went out of business after several years of big companies or the buyout. Micro-inverter commitment, because a single inverter for each solar cell module, the system as a whole will have a better performance.
However, the micro-inverter is connected to the back of the rather conventional inverter modules each solar module, also known as string inverters, is installed on the ground, usually in the home and garage is different from that of a micro-inverter the conventional inverter drive for about 30 single solar cell module conversion efficiency. Therefore, the use of micro-inverter, 30 micro-inverters will be installed at the solar array roof of a typical family.
Micro-inverter supporters believe conditions degrade the performance of the system, such as a solar cell module coloration differences, between pollution and electrical characteristics are reduced or minimized, since the solar cell module is only such conditions will be affected and all other The module will operate their best to increase the overall efficiency of energy production.
There is no basis on micro-inverter, data compiled dozens of actual real-world systems, offer than the traditional string inverters calculate the increase in energy harvest. However, in rare cases, micro-inverter is in a string inverters a better choice, as in the roof space of the house there are a number of different directions and an inverter MPPT tracker will not work or when the system is materially shadows. Otherwise, it is the author's micro-inverter, so as to avoid comments.
In dozens of system we have installed and micro-inverter in the customer's requirements, have had inverter failure. This makes sense, why we do not want to use this technology for all customers. Think about it, micro-inverter is an electronic device, which are mounted on the back of a solar module temperature exceeds 150 degrees.
Now, when a micro-inverter fails, it is not an easy fix, technical staff to get on the roof, tearing down the entire array to the inverter array fails, install a new micro-inverter, and re-install the system. It sounds like a good idea? It is disturbing to see that some of our competitors have to offer micro-inverter standard.
In about two years, they will spend most of their time doing service call failed system. This may lead to the demise of their business, then we will have to serve these isolated systems. I do not care, but definitely not good for the local industry as a whole. If you're a homeowner looking to the sun has not been micro-inverter.
