Fronius Primo GEN24 5kW/6kW/8kW/10kW Single Phase Solar Inverter

The Fronius Primo GEN24 is a premium single-phase inverter range designed for residential solar systems, available in 5kW, 6kW, 8kW and 10kW power classes. Combining flexible PV design, integrated basic backup power, intelligent energy management and extensive connectivity, the GEN24 provides a strong foundation for modern home energy systems. Two independent MPPTs allow flexible array design across different roof orientations, while Fronius Dynamic Peak Manager helps optimise solar yield under partial shading. Integrated Active Cooling protects internal components from excessive heat and supports consistent performance and long service life. The IP66 enclosure enables indoor or outdoor installation, and open communication interfaces make integration with Fronius and compatible third-party components straightforward. SUITABLE APPLICATIONS The Fronius Primo GEN24 range is well suited to: Residential single-phase solar systems Homes with multiple roof orientations Rooftops affected by partial shading New and upgraded residential PV installations Homes requiring basic backup power High solar self-consumption applications Smart-home and energy management systems EV charging and solar-powered hot water applications Homes planning for future battery storage upgrades KEY FEATURES Single-phase 220/230V grid connection 2 independent MPPTs Up to 15kWp PV generator capacity Dynamic Peak Manager for shaded conditions Integrated PV Point basic backup up to 3kW 65–600V DC input voltage range Fronius Active Cooling technology IP66 indoor/outdoor protection WLAN, Ethernet and RS485 connectivity Open interfaces for flexible system integration Integrated datalogger and web server Remote monitoring and maintenance via Fronius Solar.web MODEL COMPARISON Specification Primo GEN24 5.0 Primo GEN24 6.0 Primo GEN24 8.0 Primo GEN24 10.0 Rated AC Output Power 5,000W 6,000W 8,000W 10,000W Max.

Maximum supported PV generator capacity scales with inverter size: Primo GEN24 5.0 – up to 7.5kWp Primo GEN24 6.0 – up to 9kWp Primo GEN24 8.0 – up to 12kWp Primo GEN24 10.0 – up to 15kWp All four models operate across a 65–600V DC input range and begin feeding power from an 80V input voltage. Dynamic Peak Manager Fronius Dynamic Peak Manager is designed to improve energy yield where PV modules experience partial shading. Rather than relying solely on a conventional maximum power point, the system searches for the optimum operating point of the array, helping the inverter make better use of available solar generation under changing conditions. INTEGRATED PV POINT BACKUP PV Point provides an integrated basic backup power option without requiring a battery as part of the standard GEN24 installation. During a grid outage, PV Point can supply a dedicated backup circuit with up to 3,000VA when sufficient solar power is available. This provides a practical way to maintain selected essential loads during daylight hours without installing a complete household backup system. FUTURE-READY BATTERY UPGRADE The standard Primo GEN24 is primarily a PV inverter and does not include battery connectivity as standard. For homeowners who want to add energy storage later, Fronius UP.storage provides an upgrade path that can enable battery connection and Full Backup functionality on eligible GEN24 systems. This allows the solar system to be installed first while retaining greater flexibility for future energy-storage requirements. Alternatively, the Fronius Primo GEN24 Plus is supplied as the hybrid version with battery connectivity already enabled. Availability of UP.storage and compatible configurations can vary by market. ACTIVE COOLING FOR LONG-TERM PERFORMANCE Fronius Active Cooling uses controlled air circulation to help protect electronic components against excessive temperatures. By actively managing internal temperature, the cooling system supports performance under demanding conditions while reducing thermal stress on components, contributing to inverter durability and service life. The Primo GEN24 operates across an ambient temperature range of -40°C to +60°C. OPEN SYSTEM INTEGRATION Open interfaces give installers and homeowners greater flexibility when building or expanding a solar energy system. The GEN24 can integrate with compatible Fronius products as well as supported third-party components, helping accommodate applications such as energy management, metering, heating control and other smart-energy functions. SMART MONITORING & CONNECTIVITY Integrated communication and monitoring capabilities include: WLAN 2 × Ethernet LAN 2 × RS485 Fronius Solar.web Modbus TCP SunSpec Modbus RTU SunSpec Fronius Solar API (JSON) Integrated datalogger Integrated web server 6 digital inputs 6 digital inputs/outputs Integrated emergency shut-off (WSD) These interfaces support detailed system monitoring while providing flexibility for energy management and compatible third-party integration. SAFE & DURABLE DESIGN The Primo GEN24 features an IP66 enclosure suitable for indoor and outdoor installation. Integrated protection features include: DC isolation measurement Integrated DC disconnector Reverse polarity protection Overload management Integrated emergency shut-off Transformerless inverter architecture The operating range extends from -40°C to +60°C, with permissible relative humidity from 0–100% and installation altitude up to 4,000 metres.
