Introduction
The Eveready®Energy Vault is a scalable AC coupled all-in-one battery energy
storage system (BESS). It consists of the primary unit [AS1-3KS-5.1] and an
optional secondary unit [B1-5.1-48], each rated at 5.1 kWh and expandable up to a
maximum system capacity of 20.4 kWh.
EVEREADY®ENERGY VAULT [AS1 AND B1]
The primary unit [AS1-3KS-5.1] can be used either in a stand-alone manner or
combined with a secondary unit [B1-5.1-48], allowing a wide range of energy
storage options. Each primary unit can be associated with up to 3 secondary units,
allowing a maximum battery capacity of 20.4 kWh.

Iron Phosphate (LFP) and is intended to be used as a residential solar storage
system. The primary and secondary units have a unique serial number, which can
be described as follows.
①AS1 represents the product series.
②XK refers to the rated power of the product X kW, such as 3K for 3kW.
③S represents single phase.
④XX refers to the rated capacity of the battery, e.g., 5.1 means 5.1 kWh
①B1 represents the product series.
②XX refers to the rated capacity of the battery, e.g., 5.1 means 5.1 kWh.
③XX refers to the voltage grade of the battery, e.g., 48 means 48 V.

6| Eveready®Energy Vault [AS1 and B1] – Operating Principle
Operating Principle
The Eveready®Energy Vault is designed to function seamlessly with your existing
solar PV system(s) and the utility grid. It utilises excess solar generation to
intelligently charge and discharge the battery and relies on Current Transformers
(CTs) to measure solar generation and grid based consumption. The below image
covers the key elements of the Eveready®Energy Vault system.
It can operate in several modes: Self-consumption, Time-of-use (TOU) and
Back-Up. Each mode is designed to satisfy varying energy requirements and
enable optimal use of renewable energy.
Fig. 2 Eveready® Energy Vault Installation Schematic
On-Grid Load
Back-Up Load

Operating Principle – Eveready®Energy Vault [AS1 and B1] | 7
Under Self-consumption mode, the system supplies captured solar energy
towards house loads rst and stores surplus energy within the battery. Any excess
is then exported to the grid as feed-in. If the solar generation is not enough, the
Eveready®Energy Vault system can then intelligently meet the requirement from a
combined energy draw from both batteries and the grid. When Blackout Protection
is enabled, the Eveready®Energy Vault system shall supply safe and reliable
back-up power towards selected back-up loads.
Time-of-use mode is designed to allow users to benet from energy arbitrage.
Users can set the battery to charge and discharge during specic times of the day
when energy prices are low (or high), thereby enabling maximum energy savings.
Back-Up mode allows users that have opted for Blackout Protection at the time
of installation, to customise their battery energy usage during a blackout event.
The Eveready® Energy Vault AS1 system can reserve a certain percentage of the
battery to counter a blackout event. This energy is then discharged towards a few
emergency back-up circuits, thus avoiding power interruption to essential circuits
during a blackout. In Back-Up mode, the battery system will supply power to the
loads rst and store surplus energy in the battery as emergency standby capacity.
