FRONIUS Primo 4.6-1 Light Grid-Tied Inverter

The FRONIUS Primo 4.6-1 light 4.6kW is a single-phase grid-tied inverter without a transformer. "Light" models of the Primo grid-tied inverters do not include a WLAN communication module for viewing inverter data via the internet. Models without the "Light" designation have this module built-in. All Primo models incorporate two MPPTs and have IP65 protection, but the "Light" variants lack WLAN communications for remote management and monitoring. It is ideal for meeting the needs of any home. Primo models feature a standard interface to the internet via WLAN or Ethernet and easy integration with components from other manufacturers. They include datamanager and free connection to the solarweb portal. It has a Meter interface that allows dynamic power management and consumption visualization.

The FRONIUS Primo 4.6-1 light 4.6kW inverter allows us to connect to the electrical grid without batteries, making these installations economical and highly profitable in the long term due to their low cost resulting from a simple installation and few electronic components that increase system costs.

For a grid-tied installation to function correctly, we need a group of solar panels previously calculated to meet each case's needs and a grid-tied inverter that allows us to transform the energy from the solar panels into alternating current for use. Fronius inverters have a zero grid injection system, meaning that if the solar installation is producing more energy than the house or industrial building consumes, the zero injection system allows us to reduce the inverter's power at will only in case of an energy surplus. In summary, the functionality of zero injection systems is to reduce the inverter's power when the produced energy exceeds the consumed energy.
