Hybrid Solar Power with Battery Storage

The Fronius Primo GEN24 Plus allows homeowners to store excess photovoltaic energy in a compatible battery instead of relying exclusively on immediate solar consumption or grid export.

Stored energy can be used when solar production is reduced, helping increase self-consumption and reduce dependence on utility electricity.

The manufacturer identifies the BYD Battery-Box Premium HVM US as a compatible battery family in the supplied datasheet. Battery compatibility must be confirmed for the exact battery configuration, firmware, and system design before installation.

PV Point and Essential Backup Power

The GEN24 Plus provides flexible backup options for homeowners who want greater energy resilience.

PV Point Backup

PV Point provides a dedicated backup connection that can supply compatible devices during a grid outage when sufficient photovoltaic energy is available. This function does not require battery storage, but backup availability depends on solar production and the inverter's operating conditions.

Essential Backup

The GEN24 Plus also supports an essential backup configuration that can supply a designated backup electrical system using available photovoltaic generation or energy stored in a compatible battery.

Essential backup requires additional external grid-isolation and switching equipment. The inverter alone does not provide an automatic whole-home backup installation, and backup capability must be designed around the supported system configuration.

Dynamic Peak Manager Shade Optimization

Fronius Dynamic Peak Manager is an integrated shade management algorithm that helps maximize photovoltaic energy production when modules experience partial shading.

By evaluating the solar array's operating conditions, Dynamic Peak Manager helps the inverter identify favorable operating points and reduce energy losses caused by shade.

This technology can reduce the need for additional module-level optimization equipment when the primary objective is shade management. Separate equipment may still be required for rapid shutdown, module monitoring, or other project-specific functions.

SuperFlex Design for Flexible Solar Arrays

Fronius SuperFlex Design provides flexibility for residential rooftops with different orientations, complex layouts, or varying solar exposure.

Independent maximum power point tracking supports separate optimization of compatible photovoltaic strings, allowing installers to design solar arrays around the property's available roof space.

Active Cooling and Long-Term Reliability

The Fronius GEN24 Plus uses Active Cooling Technology to help regulate internal operating temperatures and protect sensitive electronic components.

Combined with the weather-resistant enclosure and Fronius service-oriented engineering, the inverter is designed for dependable residential solar operation in a variety of installation environments.

Integrated Monitoring and Energy Management

Built-in network connectivity allows the GEN24 Plus to communicate with Fronius Solar.web and supported energy management platforms.

Homeowners and installers can monitor photovoltaic production and compatible system performance through Fronius monitoring tools.

The inverter also supports SunSpec Modbus, Fronius Solar API, and compatible metering equipment for energy monitoring and system integration.
