What is the Azzurro collection?

The Azzurro collection brings together grid-tied photovoltaic inverters and hybrid models with storage to cover everything from homes to large commercial plants. It includes single-phase equipment from 3–6 kW with 1–2 MPPT, three-phase from 8–255 kW with 2–12 MPPT, and hybrids in both 48 V (LV) and high voltage (HV) with EPS (backup) function. Its offering combines high efficiency, IP65–IP66 protection, and advanced management via app/portal and standard communications.

Advantages and limitations

• Reference efficiency (≈97–99% depending on model) and wide MPPT window to minimize losses due to mismatch or temperature.
• Robustness: IP65–IP66 enclosures, optimized cooling, and integrated electrical protections (depending on power) for continuous operation.
• True scalability: from 3 kW residential up to 255 kW with 1500 Vdc for medium/large-scale plants.
• Hybrids with EPS: operation with 48 V or HV batteries, parallelization, and intelligent management of critical loads.
• Limitations: the injection/backup power depends on the available connection and the sizing of protections and wiring.

Applications

• Residential: single-phase 3–6 kW and/or 48 V hybrids for self-consumption with batteries.
• Small business: three-phase 8–30 kW with 2–3 MPPT and centralized monitoring.
• Industrial/commercial: 40–100 kW IP66 with multiple MPPT for large rooftops.
• PV plants: 255 kW, 1500 Vdc, and up to 12 MPPT for long strings and optimized BOS.

How to choose

• Topology: pure grid if no battery is required; hybrid if backup/EPS or maximizing self-consumption is desired.
• Phases and power: 1P (3–6 kW) for homes; 3P (≥8 kW) for SMEs and industry.
• MPPT: 1–2 in residential; ≥3 for heterogeneous rooftops or multiple orientations.
• Battery: 48 V for homes and retrofit; HV (≈180–750 V) in three-phase systems with high power and efficiency.
• IP rating: IP65–IP66 for outdoor or demanding environments.

Best practices

• Size strings within the MPPT voltage range and Voc at minimum temperature.
• Balance strings by irradiance/orientation; use more MPPT when there are shadows or mixed orientations.
• Select RCDs and SPD in AC Electrical Protections according to regulations.
• For hybrids, check battery compatibility and voltage (48 V vs HV) and the required EPS power.

Comparisons within the catalog

• Single-phase grid 3–6 kW: maximum simplicity and performance for homes.
• Three-phase grid 8–255 kW: multiple MPPT and IP66 for medium/large rooftops.
• Hybrids 48 V: self-consumption with battery and basic backup (EPS).
• Three-phase HV hybrids: high performance with storage and backup for businesses.

Accessories and related collections

• Single-phase Hybrid Inverters and Three-phase for projects with batteries.
• Single-phase Grid Inverters and Three-phase for feed-in/self-consumption without storage.
• AC Electrical Protections to comply with regulations and protect equipment.

With its combination of efficiency, robustness, and hybrid options, Azzurro enables the design of reliable and scalable systems for both residential and industrial applications, optimizing energy return and service continuity.
