1Introduction
1.1 Features
The RESU®6.4 EX battery pack has the following features:
Photovoltaic system: This battery pack is designed for photovoltaic system
compatibility.
Battery management system (BMS): The battery pack’s built-in BMS moni-
tors its operation and prevents the battery from operating outside design
limitations. See Troubleshooting on page 32.
Expandability: The battery capacity can be increased by adding expansion
battery packs. Up to two expansion battery packs can be added. An ex-
pansion battery pack can be purchased either with the main battery pack
or as a separate unit. See Installing the Expansion Battery Pack on page
22.

Introduction
NOTE
A tag is attached to the gender changer side of the provided communi-
cation cable adapter. The tag is labeled as TYPE-S or TYPE-N.TYPE-S
adapters are used with most inverters, including SMA inverters, whereas
TYPE-N adapters are supposed to be used only with Nedap inverters. If
the wrong cable adapter is identied, contact LG Chem or your distributor.
