  • Page 5: Introduction

    This product is permanently wired to the home electrical service, and must be installed by a licensed electrician only. This product is a power distribution peripheral intended to be operated with the ESS. Refer to the DURACELL POWER CENTER 5KW Installation & Startup Manual for installation of the ESS.

  • Page 6: Special Tools & Hardware

    The DURACELL HUB is a power distribution center for the ESS, routing all AC power between the main and backup electrical panels. In the event of a grid outage, the DURACELL HUB will be energized by the ESS, which will island off the main electrical panel. As shown below, the PV inverter’s AC output is connected to the backup panel to support solar charging of the battery during a grid outage.

    IMPORTANT! Do not complete this connection until the customer receives permission to operate the system, and the main panel DURACELL HUB breaker is ON. The EMC will be powered when the 12V battery is connected. Failure to comply with this instruction may cause irreversible damage to the battery due to battery drainage without a charge source.

  • Page 16: Operation

    Turn ON the DURACELL HUB breaker in the main panel. Powering up the DURACELL HUB will supply power to the on-board EMC. The red and green lights on the bottom of the EMC will flash for approximately 30 seconds, indicating initialization of the EMC. Following initialization, the lights will remain solid.
