The BTS 5K Extension Base is an essential component for expanding the Sofar BTS energy storage system. For configurations involving four battery modules—such as the 20 kW E20 setup—the system should be divided into two separate stacks. Installing all four modules on a single base is not recommended. Instead, the proper arrangement requires two modules on one base with the BDU and two modules on a second base, ensuring safe and compliant installation.
