Chapter One Safety Instructions
This manual provides information about the installation, operation, and
maintenance of the Eveready Energy Vault (“Eveready”). It is targeted at qualified
personnel undertaking the Installation of the Battery Energy Storage System (BESS)
and associated equipment. It is recommended to read the entire document as well
as safety information carefully, prior to installing or operating the system. Incorrect
or improper usage can cause damage to the product, property and endanger life of
user or associated third party.
1.1 Safety Information (Symbols)
Danger: Danger to life due to high voltages of battery and electric shock.
• Only qualified personnel equipped with suitable specialist training,
knowledge and experience are permitted to install and debug the BESS.
• Before performing any work on the inverter or battery pack, please disconnect
the BESS from all voltage sources as described in this document.
• The Electrician should always wear the right Personal Protective Equipment
(PPE – Level 1) during installation and operation of the BESS.
• Do not touch any uninsulated DC cables,
• Do not place the BESS near a source of heat or ignition, such as a fire place,
electric or hot water heaters, sparks, or open flames.
• Do not mechanically damage or subject the BESS to any strong forces in the
form of deforming, piercing, or stripping down etc.

6
• Do not open the BESS or modify any of the protective devices such as Circuit
breakers, Isolators, or electrical cabling.
• Do not dispose of BESS in fire as the batteries may explode.
• Only use the BESS in its original state without any unauthorised
modifications and in proper working order.
• Do not attempt to repair the system yourself or with the help of a third-party
electrician, as this may result in injury or void the product warranty.
• Do not connect any undedicated battery pack to the BESS because it will
damage the system.
Warning: This indicates a situation where failure to follow instructions
may be a safety hazard or cause equipment malfunction. Use extreme
caution and follow instructions carefully.
• The battery modules installed in the BESS are protected by multiple
Electrical protection devices and can be operated safely during standard
operation. However, there is a potential for the electrolyte leakage from the
battery pack as well as form toxic gases if damaged mechanically or break
down. Therefore, it is recommended to proceed as follows,
• Do not install the system in extreme low/high temperatures or humidity
exceeding the permitted range.
• Do not expose the BESS to temperatures in excess of 45°C.
• Do not place heavy objects on top of the system or mechanically damage the
batteries (by piercing, puncturing, or deforming it)
• Do not short circuit the battery module or allow them to come in contact with

7
metal.
• Do not continue to use the battery module after a short-circuit event.
• Do not install the battery pack in the vicinity of any equipment
containing flammable gases or liquids.
• If the moisture penetrates the system (e.g. due to casing damage), please do
not operate the system and contact Eveready certified Distributor
immediately for further troubleshooting.
• If you come into contact with the electrolyte, please wash affected area with
water immediately, and consult a doctor immediately.
• Ensure that all relevant local and federal regulations are observed, and
electricians must be responsible for adhering to such regulations.
1.2 Symbols
Symbol Description
Hazardous voltage
Since the system is connected to the power grid, all
relevant operations on the battery must be performed by
qualified personnel.
No open flames
Install the battery away from inflammable and explosive
articles or gases. Keep the BESS away from corrosive
substances.

8
Danger of hot surface
During operation, internal components of
the equipment may release heat. Do not
touch the metal casing of the BESS when
it is running.
Attention
Install the BESS out of reach of children.
Refer to Error Codes
Please refer to the error code within this manual.
This device cannot be treated as household waste
For the correct treatment method,
please refer to Chapter 7
"Battery
Maintenance" within this manual.
CE mark
The equipment complies with low voltage and EMC
requirements.
Recycling & Correct Disposal
Proper disposal of this product will help save natural
resources and prevent damage to the environment.
Please contact your local authorities for further details.

Chapter Two Product Introduction
2.1 Introduction of System
The Eveready Energy vault is a scalable AC coupled all-in-one battery energy
storage system (BESS) and includes the following models - AS1-3KS-5.1, AS1-
3KS-10.2, AS1-3KS-15.3 and AS1-3KS-20.4 models.
The BESS systems is intended to be used for residential solar storage and can work
under several operating modes, viz. Self-consumption mode, Time-of-use (TOU)
mode and Back-up mode (refer to Appendix I), each mode catering to user’s unique
energy requirements, thereby enabling optimal usage of renewable energy.
Under Self-consumption mode, the BESS shall supply captured solar energy
towards house loads first and store the surplus energy within the battery. Any excess
is then exported to the grid as feed-in. If the Solar generation is not enough, the
system can then intelligently meet the requirement from a combination of batteries
and draw from the grid. When Blackout protection is enabled, the batteries can
supply safe and reliable back-up power towards selected back-up loads.
The primary unit [AS1-3KS-5.1] can be used independently to provide a storage
capacity of 5.1 kWh or combined with a secondary unit [B1-5.1-48] to increase the
overall battery storage capacity up to 20.4 kWh. Each primary unit can support a
maximum of 3 Secondary units.

Note: Please refrain from connecting any un-associated equipment to the Primary
unit [AS1-3KS-5.1] including any third-party batteries and/or unauthorized meters.
Please ensure any battery capacity expansion is conducted using the secondary unit
[B1-5.1-48] only.
