The future of small and medium-sized PV is in micro inverters

The inverters are a key element of photovoltaic technology , because it can convert the direct current generated by the solar cells into alternating current ready to be fed into the grid .

Traditionally, the photovoltaic panels are connected in series through an inverter of large string that converts the direct current (DC ) generated by the photovoltaic panels to alternating current ( AC ) for the connection to the network , namely that at 220 V normally used in homes.

Unlike the central inverters microinverters are attached to each module (some micro inverters are connected to a single module , the other two modules) and operate the power conversion from DC to AC , directly on the solar module and there is no risk of arcing .

The energy produced by each combination of micro- inverter module and then acts as a generator to AC 220V autonomous and independent from the rest of the system.

The micro - inverters have specific advantages over string inverters . They allow you to individually control the output of the panels and offer the tracking function of the maximum power point tracking (MPPT ) for each module , minimizing the efficiency loss in all types of conditions .

It also guarantees a simplicity of design and installation. In case of failure it is possible to identify the module involved and fix it, without having to intervene throughout the system .

In the case of systems with traditional inverters with solar panels connected in series , when any module is in shadow , the ' "domino effect" reduces the performance of the entire solar system. In the case of microinverters if the problems are never limited to a single module in the shade.

The advantages of a system with Micro Inverter:

Greater energy production up to a 20% (1 MPPT every 2 panels ) .

Eliminating domino effect.

Elimination cables D.C. high voltage .

Increased safety due to low voltage into play .

Deleting part of the field in the Civil Code

Reduction of cost of design and installation of

95% yield constant with temperature up to 85 ° C.

Detailed monitoring and continuous for each module.

Supervision available remotely and from your tablet, smartphone.

Even technology microinverter is not immune to criticism , and , for example , an estimated regards the reliability of these devices . The components required to realize a system based on microinverters are indeed many more than are needed using a single inverter and therefore , statistically , also increase the likelihood that one of these faults . To this must be added that the microinverters are more subject to high temperatures , since they are placed in proximity of the panels , in contrast to conventional inverters that can be placed in environments more repaired . Any help on this point , rather than data as a high MTBF , a parameter that is to be interpreted correctly, can be a period of particularly long manufacturer's warranty .

To this must be added that , in case of failure , it is more inconvenient to access microinverters since they are placed in proximity of the panels. Another criticism in this regard stems from the fact that the microinverters , since they are almost always completely sealed in resin for better resistance to atmospheric agents, are not repairable , unlike the conventional inverters .

The Dailye's "Guide to the microinverter " is intended to provide a general overview on the topic.
