(Optional) Connecting the battery cables between multiple stacks About this task This task is only applicable to the scenario in which four to eight batteries are connected to one inverter. On top of the first stack, an inverter is installed; while in the top of other stacks, a battery junction box has been installed on top of the stack.
Page 115 HS3 Series Prerequisite For the battery stack without an inverter, a battery junction box (BC3-TV) has been installed on top of the stack. Procedure Step 1. Prepare and connect the grounding cable to the battery junction box. Figure 5.35. Connecting the grounding cable Step 2.

HS3 Series 5.4. System connection 5.4.1. For Europe The system connection for the grid system without special requirements is as below: Note: The backup PE line and earthing bar must be grounded properly. Otherwise, the backup function may be inactive during blackout.
Page 119: For Australia And New Zealand
HS3 Series 5.4.2. For Australia and New Zealand Notes: For safety, the neutral cable of AC and backup side must be connected together. ⚫ DO NOT connect the PE terminal of the BACKUP side. ⚫ ⚫ The E-BAR and the N-BAR must be short-circuited.
