2.4 Modularity and scalability of XOLTA BAT-5 and XOLTA BAT-10
XOLTA BAT-5 and XOLTA BAT-10 can be connected in parallel on the AC side to meet higher battery power
and/or energy requirements. The parallel connection also enhances system reliability and availability.
In the parallel operation, the following scenario is possible:
• XOLTA BAT-5 and/or XOLTA BAT-10 systems work as one unit by equally sharing charge/discharge power;
Up to 3 XOLTA BAT-5 or up to 3 XOLTA BAT-10 battery systems can be connected on the AC side (both on
the same grid phase or the different grid phases). The resulting battery power and energy capability are
presented in Table 2.1 (XOLTA BAT-5) and in Table 2.2 ( XOLTA BAT-10).
