Storage solution BPT-S 5 Hybrid
Bosch Power Tec’s fully integrated energy management systems are designed to increase own consumption of locally generated PV power. The BPT-S 5 Hybrid is a combination of a transformerless 5 kW inverter, a lithium-ion battery with a capacity from 4.4 kWh up to 13.2 kWh and a management system with a colour touch screen display.

Integrated energy management system
The BPT-S 5 Hybrid is a combination of a transformerless 5 kW inverter, a lithium-ion battery with a capacity from 4.4 kWh up to 13.2 kWh and a management system with a colour touch screen display. According to the requirements the energy produced by the PV plant is consumed directly, stored in the battery or fed into the public grid. Only if neither the PV plant nor the battery are able to supply sufficient energy, mains power is used.
Optimisation of own-consumption
With the help of the save option of the BPT-S 5 Hybrid, the use of PV electricity can be time-delayed. This makes it possible to use the battery electricity generated in the day at night. The internal consumption of PV electricity in a 4-person household can therefore – compared to a PV system without a storage system – be increased from approx. 30 % to approx. 70 %. Thanks to the high charge performance of 5 kW even daytime peak loads are covered. During the summer months it is thus possible to achieve 100 % independence from the public electricity grid.
Intelligent system management
The system is equipped with a comprehensive monitoring system. The large touch screen display shows all of a household’s electricity consumption data and the status and output data of the PV system and battery – clearly and in real time. The system has an intelligent system management function that controls and monitors energy flows and checks all components are working. The battery management system ensures that the lithium-ion batteries are charged and discharged in the optimum manner and thus last for a long time. Furthermore, the system can be monitored with e.Web and the e.UserApp regardless of location and without further accessories
