Fronius Primo GEN24 Grid-Tied Inverter with PV Point Backup

The Fronius Primo GEN24 is a high-performance, single-phase grid-tied solar inverter designed for residential photovoltaic systems. Combining intelligent shade management, integrated backup functionality, advanced system monitoring, and active cooling, the GEN24 delivers efficient solar energy conversion with flexibility for future energy storage upgrades.

Unlike conventional grid-tied string inverters, the Primo GEN24 includes Fronius PV Point, which can supply a designated backup circuit directly from available solar production during a utility outage, without requiring a battery. Its battery-ready architecture also allows eligible systems to be upgraded to GEN24 Plus functionality through Fronius UP.storage.

Key Features and Benefits

• PV Point Backup Power: Provides a dedicated solar-powered backup output during grid outages when sufficient sunlight is available, without requiring battery storage.
• Dynamic Peak Manager: Integrated shade management optimizes string performance and helps reduce energy losses caused by partial shading.
• SuperFlex Design: Flexible PV string configuration accommodates different roof orientations and array layouts.
• Independent MPPT Inputs: Supports efficient operation of solar arrays with different orientations or operating conditions.
• Active Cooling Technology: Fan-assisted cooling helps regulate internal temperatures, protecting sensitive power electronics.
• Battery-Ready Architecture: Supports future activation of compatible battery functionality through the optional Fronius UP.storage software upgrade.
• Integrated Arc Fault Protection: Fronius Arc Guard provides built-in arc fault detection and interruption.
• Built-In System Monitoring: Integrated WiFi, Ethernet, data logging, and Fronius Solar.web connectivity provide access to system performance information.
• Outdoor-Rated Enclosure: Weather-resistant construction supports approved indoor and outdoor installations.
• Smart Grid Compatibility: Supports advanced grid interconnection and energy management functions.

PV Point Backup Power Without a Battery

The Fronius Primo GEN24 offers a practical advantage over traditional grid-tied solar inverters: its integrated PV Point backup feature.

When utility power is interrupted, PV Point can supply electricity from the connected solar array to a designated backup output, provided sufficient solar production is available. This allows compatible loads to operate during daylight hours without requiring a battery storage system.

PV Point is intended for a dedicated backup circuit rather than automatic whole-home backup. Available power varies with sunlight, and the output does not provide continuous power after solar production stops.

Upgrade to Hybrid Battery Storage with Fronius UP.storage

The Primo GEN24 is designed with future energy storage expansion in mind. Through the optional Fronius UP.storage software upgrade, an eligible GEN24 inverter can be converted to GEN24 Plus functionality, enabling connection to approved high-voltage battery storage systems.

Once upgraded and configured with compatible equipment, the inverter can support battery charging, stored-energy use, and expanded backup capabilities.

Full Backup functionality requires a compatible battery, external grid-isolation equipment, and an approved system configuration. The UP.storage upgrade and additional equipment are not included with the standard GEN24 inverter.

Intelligent Shade Management with Dynamic Peak Manager

Fronius Dynamic Peak Manager is an integrated shade management algorithm that helps optimize solar production when modules experience partial shading.

Rather than relying entirely on external module-level optimizers, Dynamic Peak Manager continually evaluates operating conditions to identify the optimal power point for connected PV strings.

Combined with Fronius SuperFlex Design, the inverter accommodates a variety of residential roof layouts, including installations with different module orientations.

Integrated Monitoring and Energy Management

The Primo GEN24 includes built-in connectivity for Fronius Solar.web monitoring, allowing homeowners and installers to review solar production and system performance.

Ethernet and wireless networking support convenient connectivity, while Modbus communications enable integration with compatible monitoring and energy management equipment.

The inverter also supports Fronius Smart Meter integration for additional visibility into energy consumption and grid interaction.
