FRONIUS Symo 3.7-3-S Light 3.7kW Grid-Tie Inverter

The FRONIUS Symo 3.7-3-S Light 3.7kW is a three-phase grid-tie inverter. The S variants incorporate a MPPT (Maximum Power Point Tracker) or solar tracker, while the M models have 2 MPPTs. It is ideal for small-scale self-consumption installations.

Features

• Flexible design perfect for irregular surfaces and roofs with different orientations.
• Standard internet interface via WLAN or Ethernet.
• Easy integration with components from other manufacturers.
• Includes datamanager and free connection to the solarweb portal.
• Meter interface allows dynamic power management and consumption visualization.

The FRONIUS Symo 3.7-3-S Light 3.7kW is a grid-tie inverter that allows us to connect to the electrical grid without needing batteries. This type of installation is economical and very profitable in the long term due to its low cost, resulting from a simple installation with few electronic devices that increase the system's price.

How Grid-Tie Installations Work

For a grid-tie installation to function correctly, we need a group of solar panels previously calculated to meet each case's needs and a grid-tie inverter. This inverter allows us to transform the direct current (DC) energy from the solar panels into alternating current (AC) so that it can be used.

Fronius inverters have a zero grid injection system, meaning that if the solar installation is producing more energy than being consumed, the inverter will reduce its output power to prevent energy from being poured back into the grid.
