Introduction
Each AES RACKMOUNT Slimline Enclosure and Quick Stack Rack can be loaded with
up to six AES RACKMOUNT Battery Modules.
In a closed-loop configuration, connect in parallel up to six Slimline
Enclosures or six Quick Stack Racks for an energy storage system with up to 36
Battery Modules. In an open-loop configuration, the number of Slimline
Enclosures or Quick Stack Racks that can be paralleled is limited by only the
busbars, AIC, and the ability to charge.
The following describes how to electrically connect Slimline Enclosures or
Quick Stack Racks in parallel, and how to connect them in a closed-loop
configuration.

WIRING AND COMMUNICATION
Wiring
WARNING
HAZARD OF ELECTRIC SHOCK AND FIRE
- Battery capacity must accept the maximum charge current of the system or curtail the charging to below the operating limit of the installed batteries. Derive this value by adding the charge capacities of all inverter chargers and solar charge controllers in the system.
- Battery peak capacity must support the surge requirements of the load attached to the inverter. Match all inverter peak power values with the sum of all battery peak current values.
- Configuration and installation should only be performed by qualified personnel.
- Size the wires, busbars, and any other connections under the maximum loads and follow codes and regulations under the local Authority Having Jurisdiction.
- Size fuses and disconnects to handle AIC and peak current.
- Review the commissioning checklist in the Slimline Enclosure or Quick Stack Rack manual before electrifying the system.
Failure to follow these instructions may result in death or serious injury.
This manual provides only example configurations and is not a comprehensive guide to the programming and configuration of a specific installation. Each installation may have unique conditions or use cases that require modification or adaptations of values. Installers must be capable of reviewing and adapting to the specifics of an installation and its specific use case, optimising equipment and settings where needed, and following codes under the local authority having jurisdiction.
NOTE
Installation
- Minimum cable lengths. To reduce the voltage drop from impedance, which could lead to reduced performance, select a location that minimizes the length of battery cables.
- Appropriate cable gauge. The cables should be capable of carrying the normally expected current, plus a margin of safety.
- Proper polarity. Confirm the polarity of all cables and terminal connections. Positive (+) is connected to positive (+), and negative (-) is connected to negative (-).
Grounding
WARNING: HAZARD OF ELECTRIC SHOCK
- For grounding specifications, follow codes and regulations under the local authority having jurisdiction.
- Failure to follow these instructions may result in death or serious injury.
Closed-Loop Communication
Closed-loop communication between the AES RACKMOUNT battery modules and
inverter chargers is achieved through the LYNK II communication gateway.
NOTICE
- Only one LYNK II communication gateway is required for the LYNK network.
- One LYNK network can support up to 36 AES RACKMOUNT Battery Modules. The total length of the LYNK network cables must not exceed 36 m (118.11 ft).
- Do not pass communication cables through the same conduit as power cables. For best practice, use shielded communication cables.
EXAMPLE SYSTEM
EXAMPLE SYSTEM: AES RACKMOUNT SLIMLINE ENCLOSURE
CAUTION
EQUIPMENT DAMAGE
- Follow instructions in the relevant manuals when installing, wiring, and commissioning the system.
- Torque all connections as specified in the manual.
- Failure to follow instructions in the manual will void the warranty.
Failure to follow these instructions may result in injury.
Wiring Example: Slimline Enclosures in Parallel
| Item | Description |
|---|---|
| 1 | Select the number of inverters as required by the application. |
| 2 | Positive/Negative wires between the inverter and busbars, and between the |
busbars and the Enclosures. Each Enclosure requires two positive and two
negative wires to carry the 500 A maximum current available on the busbar, and
to utilize the two separate connections for breakers or fuses in the
Enclosure.
Item| Description
---|---
3| Positive and negative busbars. Size busbars to handle the maximum current
of the system.
In this example, the three Slimline Enclosures are rated at 500 A each for a total of 1500 A. To allow for overcurrent, consider using a 2,000 A busbar.
4| Disconnects between power conversion equipment and energy storage. Some regions require disconnects in both the positive and negative cables. Others require the disconnect in the positive cables only. Refer to the applicable code and check with the authority having jurisdiction to confirm local requirements.
Overcurrent protection is recommended inline for all positive conductors.
5| This example (above) has three Slimline Enclosures, each with six Battery Modules, for a system with a total of 18 batteries.
In an open-loop configuration, the number of Slimline Enclosures that can be paralleled is limited by only the busbars, AIC, and the ability to charge. In a closed-loop configuration with a single LYNK II communication gateway, a maximum 36 Battery Modules in six Slimline Enclosures can be paralleled.
6| The minimum spacing between enclosures is 44.45 mm (1.75 in). More space
may be required depending on the wires and grommets in the installation.
NOTICE
Protect all cables from sharp steel edges with cable glands, nipples, or
conduits.
NOTE
• Each Slimline Enclosure has unpopulated positions for two DC breakers. When fully populated with six Battery Modules, two 250 A DC-rated breakers are recommended. When fully populated with six Battery Modules, two appropriately
sized positive power cables would be required, one for each DC breaker mounted in the Slimline Enclosure. Two appropriately sized negative power cables would also be attached to the negative bus bar inside the Slimline Enclosure.
• Each AES RACKMOUNT Battery Module is equipped with a built-in 100 A breaker to protect the power terminal.
