Fronius Primo GEN24 6.0 6kW Single-Phase Grid Inverter

About This Product

The Fronius Primo GEN24 6.0 6kW Single-Phase Grid Inverter is a grid-connected string inverter designed for residential solar installations and compatible single-phase electrical systems. Part of the Fronius GEN24 platform, this model converts DC electricity generated by solar panels into usable AC electricity for on-site consumption and grid export where permitted.

The Fronius Primo GEN24 6.0 supports 208V and 240V AC applications, making it suitable for appropriately configured US electrical services. Its transformerless design, integrated system monitoring capabilities, and flexible PV string configuration support professional solar installations. This is the standard grid-connected GEN24 model rather than the GEN24 Plus hybrid version.

Who This Product Suits

The Fronius Primo GEN24 6.0 is suitable for homeowners and solar installers planning a residential grid-tied photovoltaic system using a compatible single-phase electrical service. Its 6kW AC output rating makes it a practical option for residential solar arrays designed around the inverter’s electrical operating limits.

It is particularly useful for installations requiring string-level inverter architecture, flexible panel arrangements, and system performance monitoring. Installers should confirm PV module compatibility, string voltage limits, utility interconnection requirements, and applicable National Electrical Code (NEC) provisions before installation.
