Fronius Primo 4.6 - 1 Light grid inverter with innovative design gets the maximum performance from rooftop installations.


Product description:
Within the SnapINverter range and with a power range between 3.0 and 8.2 kW, the Fronius Primo single-phase inverter is the perfect equipment to meet the needs of any home. Thanks to its double MPPT and its innovative SuperFlex design, it is capable of getting the most out of rooftop installations. With the SnapInverter mounting system, installation and maintenance are easier than ever. The Fronius Primo inverter can be optionally completed with a Fronius Smart Meter, which is equipment that sends the most complete information to the monitoring system, also ensuring that the inverter does not inject energy into the electrical grid.

The solar inverter or solar converter is an essential element in any photovoltaic solar installation, in addition its power largely defines the dimensioning of the installation, so it is very important to choose the most suitable one for your needs. There are several types of inverters depending on the production and storage capacity of each facility. Its main function is to transform the direct current from the solar panels or solar batteries (12V, 24V or 48V), into alternating current (230V), which will be distributed throughout the home or place where electricity is consumed.
There are several types of solar inverters among which we can highlight:
- Sine wave inverters (can be with or without charger)
- Hybrid sine wave inverters (they already have a built-in regulator) (they can be with or without equalization)
- Modified Wave Inverters (can be with or without charger)
- Self-consumption inverters and grid connection, which can be single-phase or three-phase.

For the correct operation of the solar inverters, we must take into account the VA (Volt Amperes), since they must be 20% above the sum of the watts consumed, taking into account that some devices that we can have in the installation have peaks of very high start-up, so we must choose the solar inverter model with sufficient capacity to absorb these possible consumptions.

With its power ranges from 3.0 to 8.2 kW, the Fronius Primo rounds off the SnapINverter generation perfectly. This transformerless single-phase equipment meets the needs of any home. Its innovative SuperFlex design offers maximum flexibility in system design and together with the SnapINverter mounting system, installation and maintenance are easier than ever. It includes a communications package with WLAN connection, energy management, numerous.
