Three-phase storage system 20kW Verto Plus inverter 20kWh Fronius Reserva Pro lithium battery

The new three-phase inverter Fronius Verto Plus is designed to provide full backup, high performance even in complex conditions, and maximum protection for both the system and data.

Main Features

• Full Backup and heavy load management: provides energy to entire buildings during emergencies and efficiently manages machinery, heat pumps, and industrial systems.
• High flexibility: 3 MPPTs with a wide input voltage range and Dynamic Peak Manager to optimize module performance even under shading.
• Integrated safety: overvoltage protection, Fronius Arc Guard for fire prevention, and data protected according to European standards.

Fronius Reserva Pro is the storage solution for commercial businesses, farms, and large residential complexes that want to manage electricity supply more efficiently and independently.

By integrating with Verto Plus or GEN24 Plus hybrid inverters, it creates an energy system that reduces electricity costs through self-consumption and optimized charge/discharge management.

Together with a backup system, it can supply energy even during voltage fluctuations or blackouts, ensuring operational continuity of machinery, refrigeration units, ventilation systems, or other equipment.

The modular structure of Fronius Reserva Pro allows customized storage solutions, from 12 to 32 kWh per single tower. The system is scalable up to a total of 128 kWh usable capacity by connecting 4 battery towers in parallel.

Thanks to the high-voltage DC coupling technology, energy produced by the photovoltaic system is stored with maximum efficiency, minimizing conversion losses. Additionally, with Fronius Verto Plus, the charge/discharge capacity can reach a maximum power of 28.3 kW – ideal for commercial and agri-solar applications.
