How Many MPP Trackers does the Fronius Primo Solar Inverter have?
Each Primo solar inverter has two Maximum Power Point (MPP) trackers that you can track with their Dynamic Peak Manager (DPM).
MPP Trackers work with a wide range of input voltage for DC power and a high voltage system to maximise power extraction under different weather conditions. It also optimises the match between the solar panels and the Primo inverter for maximum power generation.
Fronius has the latest MPP tracking dynamic algorithm called the Dynamic Peak Manager. It adjusts to the solar system’s energy usage behaviour, allowing you to focus on the optimal operating dynamics.
The Dynamic Peak Manager regularly checks the curves of the solar input. Additionally, it helps you find the Global Maximum Power Point of a solar panel in the partial shade and track the average power by monitoring the minimum and maximum input ratio.
Does the Fronius Primo Inverter come with an Internal DC Circuit Breaker?
No, Fronius Primo inverters do not have an internal DC circuit breaker. However, they recommend a type A residual current circuit breaker with a trip current of at least 100 mA for their AC connecting cable if it’s required by local regulations and the power supply company.
A residual current circuit breaker (RCCB) is a safety and current sensing device that automatically measures and disconnects circuits whenever a fault happens or excess solar energy surpasses the sensitivity rate. Type A specifically ensures tripping on residual AC currents and residual pulsating DC currents.
Generally, RCCB provides fire protection and protection against earth fault and leakage current. It also offers protection against voltage fluctuation with its filtering device that monitors transient voltage levels. A possible dual termination for cable and busbar connections can also be done when needed.
Fronius Primo Key Features
Fronius is a leading solar inverter brand with good reason; its inverters possess a wealth of features. These include:
- SnapInverter Technology
Many PV systems globally have utilised the benefits of SnapInverter technology. The futuristic but straightforward standardised mounting system allows for easy installation and servicing. It’s also innovative and completely safe.
The design has a unique feature: the connection point and the power component set section are separate. This means the two are installed separately. This ingenious hinged system enables user-friendly installation and maintenance.
You’ll fit the light connection point and all its cabling first, which the power compartment set will follow.
Before securing the Fronius Primo inverter, you’ll have to place it in an already fixed wall bracket. So if you need to service the inverter, you won’t have to remove the whole model. Instead, you can release the power compartment set. The entire cabling system will be left in place.
The Fronius inverters offer maximum flexible usage as well as integrated functions to help you achieve your top self-consumption rates.
- Integrated Data Communication
Fronius Primo solar inverters include the quality of totally integrated data logging. This targets a communication package that uses various interfaces, including Web Server, WLAN, Ethernet, and Energy Management.
The inverter provides the optimal process overview for the PV system. The technology includes third-party associated connectivity to interfaces like Fronius Solar API, Modbus RTU SunSpec, and Modbus TCP SunSpec.
The open interfaces with each Fronius inverter also allow parallel running with the Solar.web platform.
- Dynamic Peak Manager
The new MPP (Maximum Power Point) algorithm for tracking called Dynamic Peak Manager dynamically modifies its behaviour by searching for the best operating point.
This unique feature automatically inspects the whole characteristic curve regularly. It does this to reach the GMPP (Global Maximum PowerPoint).
- Integrated Superflex Design
The innovative Superflex design for the Fronius inverter offers the utmost flexibility. It combines impressive technical performance features that make your PV installation process painless and straightforward.
The design encompasses two MPP trackers, an elevated system voltage, and a wide voltage range for a DC input.
Each DC input, and thus each MPP tracker, can absorb the total nominal output associated with the Fronius inverter.
Any Fronius inverter with the design will meet the demands of every running PV system plan within one inverter model. This is possible regardless of where the solar inverter is installed, including irregular roof designs, residual module usage, etc.
- Smart Grid-ready Inverter
Fronius Primo inverters are Smart Grid-enabled. They have been equipped to meet the technical requirements of any future grids.
There are several intelligent functions called Advanced Grid Features. These features are integrated into the gadgets and comprise various control functions targeting optimal feed-in associated with reactive and adequate power.
The smart function design enables a stabilised grid operation with no downtime. This is useful when there’s a very high density in the PV setup. It’s also helpful in preventing any feed-in interference or interruptions linked to yield losses if grid parameters go beyond the thresholds.
Therefore, with Fronius inverters, there’s a guaranteed yield.
Still, in the event of any imposed feed-in restrictions or limitations, the Primo inverters offer dynamic control to the feed-in while capably managing self-consumption. Connecting the meter and setting the top feed-in limit is your only real work.
- Zero Feed-in Feature
As grid operation numbers increase globally, there’s a stipulated PV feed-in top limit for power as a pre-condition before connecting your system to the solar grid.
Due to the dynamic reduction in power, Fronius has provided a much-needed solution that allows for top feed-in management.
This is where the Fronius inverter supplies energy to household consumers before adjusting the system’s output to the optimal energy feed-in according to the grid operator’s permit.
The zero feed-in associated with these inverters means you won’t need to feed any PV power to the grid.
You can activate the critical grid operator requirements by simply enabling a specific setting found on the web interface for the Fronius inverter.
- Active Cooling System
Primo inverter cooling is achieved via a fan-forced air system to enable active cooling. Even though active cooling is somewhat complex, it’s known to enhance performance and reliability compared to standard solar systems that utilise passive cooling.
- Easy Monitoring
Primo solar inverters have easy monitoring because it is suitable with WLAN-enabled system monitoring Fronius Datamanager 2.0 as standard. Its system monitoring includes a dedicated web page that displays current data and a wide range of settings. It also connects to Fronius Solar.web using WLAN or LAN.
Additionally, the system sends automatic service messages via SMS or email in the case of a fault.
There is also a Fronius Solar.web app that is available for both Android and iOS. You can monitor and view the current solar generation and estimated savings in the app. You can also chart your detailed operating statistics like the voltage and grid voltage.
Using connected meters, you can also add a Fronius smart meter to control the Primo inverter. The smart meter also lets you monitor energy generation and consumption and can be a perfect addition to completing your monitoring system.

The Fronius brand is already well-established within the extensive solar sphere and produces highly reliable and quality solutions globally.
The solar inverter is still a great product, putting aside the disappointing warranty, high cost, and noise resulting from the cooling system.
But if affordability is among your top priorities, then the Fronius Primo might not be your best choice.
Due to the price tag, the warranty really should be more competitive. The positive side is that you can extend the Fronius warranty if necessary.
In terms of fan noise, installing your solar inverter away from your bedroom or living space is advisable.
Overall, the Fronius Primo inverter is a reliable purchase due to the company’s reputation. Its quality performance and unique system features make it an excellent investment.
Besides acquiring a suitable solar inverter, the most crucial aspect of investing in a solar system is ensuring the installation is accomplished correctly. That’s why you need a reputable company to install your solar panel.
