The FRONIUS Symo 12.5-3-M light 12.5kW Grid Connection Inverter is a three-phase grid connection inverter. The S variants incorporate an MPPT or maximum power point trackers, while the M have 2 MPPT. It is ideal for small power self-consumption installations.
Characteristics of the Grid Connection Inverter FRONIUS Symo 12.5-3-M light 12.5kW
The FRONIUS Symo 12.5-3-M light 12.5kW Grid-Connection Inverter is a three-phase, transformer-free grid-connected inverter.
Grid connection inverters that have the “Light” designation are those that do not have the WLAN communication module installed to be able to view the inverter data over the Internet, those inverters that do not have the “Light” designation do. Incorporated.
Those grid connection inverters with the designation “S” incorporate only one MPP, while Symo grid connection inverters that incorporate the designation “M” incorporate 2 MPP.
Applications and features of the FRONIUS Symo 12.5-3-M light 12.5kW Grid Connection Inverter:
The FRONIUS Symo 12.5-3-M light 12.5kW Grid Connection Inverter is a three-phase grid connection inverter. The S variants incorporate an MPPT or maximum power point trackers, while the M have 2 MPPT. It is ideal for small power self-consumption installations.
Thanks to its flexible design, the Symo model is perfect for installations on irregular surfaces and for roofs with different orientations.
The S and M models have a standard internet interface via Wlan or Ethernet and easy integration with components from other manufacturers, including datamanager and free connection to the solarweb portal. The light models lack communication interfaces, but they are prepared in case they wanted to be added in the future.
It has a Meter interface that allows dynamic power management and consumption display.
The FRONIUS Symo 12.5-3-M light 12.5kW Grid Connection Inverter is an inverter that allows us to interconnect with the electrical grid without the need for batteries, which is why this type of installation is economical and very profitable in the long term, given its low cost from a simple installation and few electronic devices that make the system more expensive.
For a grid connection installation to work correctly, we will need a group of solar panels, previously calculated to suit the needs of each case, and a grid connection inverter, which will allow us to transform energy from the solar panels to be able to make use of it
Fronius inverters have a zero grid injection system, this means that in the event that the solar installation is producing more energy than the home or industrial building is consuming, the zero injection system will allow us to reduce at will the power of the inverter only in the event that there is an energy surplus.
In short, the functionality of zero injection systems is to reduce the power of the inverter when the energy produced is greater than the energy consumed, thus preventing it from being discharged into the general electrical network.
