Fronius Primo GEN24 5.0 Plus — is a high-efficiency single-phase hybrid inverter with a capacity of 5 kW, designed to ensure maximum energy independence for private households. The device combines the functions of a grid-tied inverter and an intelligent battery charge controller, allowing you to use solar energy for electricity supply, heating, cooling, and electric vehicle charging even at night. The Plus series model is equipped with a built-in battery connector and supports extended backup power options for any situation.
Technical Decoding of Primo GEN24 5.0 Plus Model
Each characteristic in the FR5-01PRGP designation indicates advanced technological capabilities of the device:
- Primo: Single-phase design (1-NPE 220/230 V), specifically adapted for the private residential sector.
- GEN24 Plus: Hybrid platform with a built-in battery interface and two backup power options (PV Point and Full Backup).
- 5.0: Rated AC output power is 5 000 W (5 kW).
- 2 MPPT: Two independent maximum power point trackers allow efficient management of panel arrays on roofs with complex geometry.
5 Key Technical Advantages of Fronius Primo GEN24 5.0 Plus
1. High Current Throughput (22 A per MPPT1)
The inverter's first MPP tracker supports input current up to 22 A, and the second up to 12 A. This ensures compatibility with modern high-power solar panels. The maximum array short-circuit current is 41.25 A for MPPT1 and 22 A for MPPT2.
2. Flexible Backup System: PV Point and Full Backup
The inverter offers two operating modes during network failures: PV Point (basic power supply to critical loads up to 3 kW directly from the sun even without a battery) and Full Backup (full power supply to the entire house when a battery is available). In Full Backup mode, the device provides a rated power of 5 000 VA.
3. Active Cooling Technology
An integrated active air cooling system protects sensitive electronics from overheating. This extends the inverter's service life and guarantees stable operation even at high ambient temperatures up to +60 °C.
4. Wide Operating Range and Low Startup
The inverter starts operation at a voltage of 80 V (Udc start). The MPP voltage operating range is from 65 to 530 V, allowing the system to generate energy from dawn to dusk.
5. Compatibility with High-Voltage Batteries
The system is optimized to work with BYD Battery-Box Premium HVS/HVM batteries and the proprietary Fronius Reserva system. DC-coupling architecture ensures minimal losses during energy storage and transfer.
