Fronius Primo GEN24 3.0 — is a high-tech single-phase grid-connected inverter with a rated power of 3 kW, designed to optimize the operation of small residential solar power plants. The device is part of an innovative GEN24 product line that combines legendary Austrian reliability with modern energy management and backup power supply features. Thanks to its compact architecture and high efficiency, it provides stable power generation for the needs of modern households.
Technical Interpretation of the Primo GEN24 3.0 Model
The inverter marking reflects its key design and functional features:
- Primo: A series of single-phase devices (1-NPE 220/230 V), developed specifically for the private residential sector.
- GEN24: A new generation of Fronius platforms that includes an integrated PV Point basic backup power function.
- 3.0: An indicator of the rated AC output power, which is 3 000 W (3 kW).
- 2 MPPT: The presence of two independent maximum power point trackers allows for efficient management of panel arrays on roofs with complex geometry or different orientations.
5 Key Technical Advantages of Fronius Primo GEN24 3.0
1. Basic Backup Power PV Point
The inverter is equipped with an integrated PV Point function, which provides power to a dedicated socket of up to 3 000 VA in case of main grid failure. This allows critical appliances (refrigerator, lighting, device charging) to remain operational directly from solar energy even without using a battery.
2. High Input Current Capacity (22 A on MPPT1)
The first MPP tracker supports input current of up to 22 A. This ensures full compatibility with modern high-power solar modules that have high operating current ratings and allows minimizing energy losses during periods of maximum sun activity.
3. Active Cooling Technology
The built-in intelligent active air cooling system continuously monitors the temperature regime of components. This not only protects sensitive electronics from overheating, but also guarantees stable full-power operation at ambient temperatures up to +60 °C.
4. Ultra-Low Startup Voltage and Wide MPP Range
The inverter starts generating energy at a voltage of 80 V (Udc start). The MPP operating range is from 65 to 530 V, which allows the system to start operating at dawn and continue generating power until late dusk.
5. Capability to Upgrade to a Hybrid System
Thanks to the Fronius UP.storage software update, the GEN24 grid-connected inverter can be upgraded with a battery connector at any time. This allows you to convert the system to a hybrid system with Full Backup function without replacing the main equipment.
