The network inverter included in the solar panel system converts the direct voltage supplied by the solar panels into normal 230V alternating voltage. Traditionally, inverters have needed a high DC voltage to operate, which is why a large number of panels have had to be installed.

With the development of inverter technology, high voltage is no longer needed, but even a single solar panel can be connected to the property's electrical network. This type of inverter is called a microinverter and is panel-specific. The inverters are connected to each other and the desired number of solar panels can be chained together in the system.

A solar panel system implemented with microinverters is simple and easy to implement. You can start building a solar panel system with just one panel, and as your appetite grows, you can expand the system as you wish.

The inverter feeds out normal 1-phase 230V plug-in electricity, so a standard electric cable leaves the inverter chain and is connected to the power station. So there is no need to connect special cables for transporting high direct voltage to the roof.

The electricity produced by the solar panels goes directly to the property's own use. Thanks to its small size, the inverter can be installed directly behind the solar panel in the same rack to which the panel is attached. Cabling is simple to implement: the solar panel is connected to the inverter, the inverters are connected to each other, and a standard electric cable is routed down from the roof.

A total of 20 microinverters can be chained in a row. When installing several panels, these are connected to two or more chains. If you want to connect the panels to a 3-phase system, this is done by connecting three panel chains, each to its own phase in the electrical center.

Production measurement and control

The system includes ECU monitoring as a part, which monitors the operation of each panel. The device collects the production data of individual panels, which can be monitored using an internet browser.

Advantages of microinverters

A microinverter has clear advantages compared to the use of individual larger inverters. Because when using microinverters, each panel works independently, failure of one panel, dirtiness or, for example, falling into the shade does not affect the operation of the other panels. When connected traditionally, the shading of one panel could drop the production of the entire row of panels. When using microinverters, high DC voltage cabling is avoided. If the panels are conventionally connected in series, the voltage they generate is several hundreds of volts. This voltage cannot be switched off, e.g. in the event of a fire, but the panel voltage remains high as long as the sun shines. In the case of a microinverter, disconnecting the power supply cable from the power center immediately stops the power supply to the inverters.

The microinverter enables an easy way to produce renewable energy for your own needs with solar panels. The amount of production can also be closely monitored.
