UNIV 14.3 kWhFS – PV storage system
The UNIV 14.3kWhFS PV storage system is designed for households and businesses with high energy requirements. It supports efficient self-consumption optimization and delivers reliable power.
With 13.48 kWh of usable energy and a continuous charging and discharging current of up to 200 amps, this storage system is ideal for applications where a lot of energy needs to be supplied or absorbed in a short space of time. The space-saving wall mounting combines high energy density with robust technology in a compact space.
The modern LiFePO₄ cell technology guarantees longevity and thermal safety. The storage system achieves over 8,000 charging cycles at 80% depth of discharge – this corresponds to more than 15 years of stable use.
An integrated battery management system (BMS) monitors each individual cell group and reliably protects against overcharging, deep discharge, overcurrent or overheating. The storage system can be combined with numerous common inverters via standardized interfaces (CAN and RS485).
The system can be expanded to up to 16 units for larger amounts of energy – without the need for costly conversions.
Technology meets application
- PV storage 14 kWh – high usable capacity for larger PV systems
- Compact wall mounting – stable, efficient and space-saving
- 200 A charging and discharging current – also for power-hungry systems
- Scalable – up to 16 memories can be operated in parallel
- Maintenance-free and noiseless – thanks to passive air cooling
- Intelligent BMS – provides reliable protection and increases service life
Typical areas of application
- Single-family homes with high self-consumption
- Apartment buildings with energy management system
- Commercial properties with peak loads (e.g. trade, offices, restaurants)
- PV-supported emergency power systems with backup function
