Fronius Primo 5.0-1 Light 5kW Single-phase Solar Inverter

Product Description

The Fronius Primo 5.0-1 Light 5kW Single-Phase Solar Inverter is designed for homes that require more power without incurring additional communication costs. With two MPPT and a wide DC range, it optimizes rooftops with multiple orientations; its SnapINverter IP65 design simplifies installation and maintenance, and integration via RS-485 allows feed-in and power control from a meter or EMS.

Main Features

• Nominal power: 5 kW single-phase; max. efficiency ≈98% (ηEU ≈97.1%).
• 2 MPPT architecture (2+2 inputs), 150–1000 V DC; typical Umpp 240–800 V.
• Integrated protections: DC isolator, insulation monitoring, and reverse polarity.
• IP65 for indoor/outdoor use, active ventilation, and front access to terminals.
• Light connectivity: RS-485 Modbus RTU (SunSpec) and digital I/O.

Advantages or Benefits

• Higher annual production with flexibility to orient strings in two zones.
• Reduced CAPEX by dispensing with WLAN/Ethernet while maintaining the same power hardware.
• Ready for zero feed-in and dynamic control with Smart Meter.
• Agile and safe O&M thanks to SnapINverter and local registration via EMS.

Purpose or Applications

Single-phase residential self-consumption, homes with medium-high consumption, integration with wallbox and DHW using surplus energy, and projects with centralized monitoring.

Technical Specifications

Compatibilities
