Kostal Piko BA – The energy storage system for numerous applications

Intelligent and powerful
The Kostal Piko BA energy storage system combines the best inverter technology with an intelligent energy management and a high-quality as well as powerful battery system. Optimum coordination of all components and their high quality bring about a system which achieves best efficiencies and ensures many years of efficient utilization.
Innovative inverter technology
With a module power between 4 and 11ákWp, the Piko BA provides charge regulator and inverter in one housing. Controlled by an intelligent energy management system, the Piko BA achieves a maximum efficiency of 96.5á%. While feed-in is effected on a demand-oriented basis, the integrated CAN interface enables the connection to the battery management system of the external storage – thus the system is optimally equipped for novel storage technologies. The overall Piko BA package is rounded off by the integrated communications and monitoring package, as well as the two independent MPP trackers.
Energy storage at a high level
The Piko battery is the optimum energy storage for the direct consumption of photovoltaic energy. High energy yield, long life, small space requirement, as well as a modular design for simple installation – all that results in a complete storage solution from one source. Moreover, operating costs are saved thanks to the system's maintenance-free battery technology. Optimum storage and management of the generated energy is ensured together with the integrated battery management system.
Advantages in brief
  • High-quality individual components, optimally adjusted to each other
  • Three-phase storage system
  • High efficiency due to the energy management of the Piko BA inverter and charge regulator
  • Energy storage with an integrated battery management system for high energy yields
  • Home consumption recording with the Piko BA sensor
