2.1 About this Manual – Target Audience

This manual is intended to be used by qualified service and installation personnel for the purposes of product
installation. This manual contains instructions for the installation and start up sequence of the Eguana Commercial AC
Battery energy storage system. This product is permanently wired to the electrical service, and must be installed by a
licensed electrician only.

This system requires an externally supplied energy management system to operate and manage the battery system.
The energy management system must be qualified and approved for use by Eguana Technologies to be compliant with
the manufacturer warranty. Consult the manufacturer for a list of approved energy management systems prior to
installation of this product.

2.2 Glossary

2.3 Initial Inspection of Material List

In addition to the battery system, the following additional components are supplied with your Eguana Commercial AC
Battery™ Energy Storage system. Each component should be inspected visually for any damage that may have been
caused by shipment. If damage is present, please contact your local distributor.

 Cabinet canopy
 Hardware kit
 Installation and Startup Guide
 Antenna (optional)

2.4 Installation materials not included

The following materials should be readily available to install the system:

 CAT 5e communication cable of appropriate length and gauge (non-integrated EMS)
 RJ-45 connectors (EMS communication)
 Mounting hardware for pad mounting of cabinet – up to ½” hardware supported.

2.5 Special Tools

In addition to standard tools required for cabinet mounting, the following tools should be readily available to
interconnect the battery and PCS cabinets.

 RJ-45 crimp tool (EMS to PCS communication cable).

Before installing the system, read all instructions and warnings in this manual.

CAUTION! All electrical and civil installation work should be performed in accordance with local building and
electrical codes.

3.1 Installation Planning

CAUTION! The cabinet weighs approximately 1500 lbs. Handle with care. All six lift points must be used to lift
the cabinet into its fixed position, and equal tension at all six lift points is required to prevent damage to the
interconnected cabinets. Ensure equipment and lift straps used are rated to safely install the system.

CAUTION! Avoid installation in direct sunlight. Battery performance is dependent upon operating ambient
temperature. Radiant heat absorbed in direct sunlight will greatly reduce the performance of the batteries and will

prematurely cause degradation of the display indicator panel on the front of the cabinet. The HVAC option will be
required where direct sunlight installation is the only option. Refer to Section 12 for more details.

3.2 Cabinet Plinth Pad-mount Dimensions

The following diagram illustrates the pad-mount footprint dimensions for the cabinet plinth, with relative position of the
field wiring ports near the front-right corner of the cabinet plinth. Anchoring of the cabinet is supported by four
mounting holes rated up to ½” (13 mm) anchor bolts.

CAUTION! Concrete pad or floor must be level to ensure proper weight distribution of rack-mount components
within the cabinet. All civil work should be performed in accordance with local building codes.

3.3 Cabinet lift method

The following diagram illustrates the lift points. The two cabinets are interconnected at the base plinth and the top
center lift hardware. Note that the product is shipped without the canopy installed, such that it is ready for direct lift off
of the shipping pallet.

CAUTION! The cabinet weighs approximately 1500 lbs. Handle with care. All six lift points must be used to lift
the cabinet into its fixed position, and equal tension at all six lift points is required to prevent damage to the
interconnected cabinets. Ensure equipment and lift straps used are rated to safely install the system.

The following block diagram is representative of an AC coupled solar plus storage system with backup power operation
(480V model only).

Important: The above diagram is a single line representation of a utility interactive battery system with AC coupled
PV to a critical load panel, based on the electrical ratings of the Eguana AC battery. Please consult your National and
local electrical codes for full compliance in an actual installation.

1 – PV Inverter should not exceed rating of base load plus battery inverter rating for optimal self-consumption and/or
where PV export to grid is not permitted.
2 – Sub-panel is grounded directly from the main panel.
3 – Refer to EMS/gateway specs for communication cabling requirements.
4 – An Automatic Transfer Relay (ATS) or Mechanical interlock is recommended in case of system service. This will
power critical loads directly from the grid.
