6. Load Qualification: Protection may occur when switching the battery module ON. The protection qualifies the load attached to it to prevent switching ON into a reverse polarity, short circuit, mixed voltage system, or large capacitive load. For trigger and recovery values, refer to Table 3-4, ELEMENT ESS Protection Specifications. - Page 16 ON, allowing you to connect battery modules at different SOC. The maximum input capacitance for a single battery module should not exceed the values in Table 3-1, ELEMENT ESS Electrical Specifications. NOTICE When switching ON battery modules, the inrush current may cause the battery modules to fault as they energize external capacitive loads.
