The Grid Inverter Fronius Primo 4.0 – 1 Light is the ideal equipment to meet the needs of any home.
Characteristics of the FRONIUS Primo 4.0-1 light 4kW Network Inverter
The FRONIUS Primo 4.0-1 light 4kW Grid-Connection Inverter is a single-phase, transformer-free grid-connected inverter.
Primo grid connection inverters that have the name “Light” 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 name “Light” do they have incorporated
Applications and features of the FRONIUS Primo 4.0-1 light 4kW Grid Connection Inverter:
The FRONIUS Primo 4.0-1 light 4kW Grid Connection Inverter is a single-phase grid connection inverter. All Primo models incorporate two MPPT and have IP65 protection, but the light variants lack Wlan communications for remote monitoring and management. It is ideal to meet the needs of any home.
Primo models have a standard internet interface via Wlan or Ethernet and easy integration with components from other manufacturers, including data manager and free connection to the solarweb portal.
It has a Meter interface that allows dynamic power management and consumption display.
The FRONIUS Primo 4.0-1 light 4kW 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. Coming from a simple installation and with 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.
