This document is valid for the ******* from firmware version ******.
This document only contains brief information and may deviate from the real system.
Any Failure to follow this document instruction will make any manufacturer's warranty,
guarantee or liability null and void unless you can prove that the damage was not due to
non-compliance.
SECU-A5.4L battery is used with GoodWe ESA/ES/EM/SBP/BP series products. The battery
is designed for indoor use. But in a ESA system, the battery is protected by the ESA
enclosure, which could be used outdoors.
The system is not suitable for supplying life-sustaining medical devices. Please ensure that no
personal injury would lead due to the power outage of the system.
Alterations to the GoodWe system, e.g., changes or modifications are not allowed unless the
written permission of GoodWe is achieved.

Note:
· The battery is designed for GoodWe ESA, ES, EM, SBP, BP series energy storage system.
Before installation, make sure battery is not damaged and battery breaker is switched OFF. And
whole energy storage system is isolated from both AC and DC power.
· Before installation and cable connection, make sure battery is not damaged and battery breaker
is switched OFF. And whole ESA cabinet is isolated from both AC and DC power.
· Battery packs shall be connected in parallel.
· Each SECU-A5.4L unit has two sets of Power Cable Connector - and ﹢, which functions the
same. Any of the two sets could be used for power connection.
· Please make sure the positive and negative pole on both battery and inverter side not reversed,
otherwise the inverter or battery could be damaged.
· The unused battery connectors must be sealed with connector cover.
· When replacing or expanding the battery system, it is prohibited to connect the battery to the
systerm , please contact the after-sales service for processing.
· Please refer to the inverter user manual for specific connectors on each inverter. We just take
SBP and ESA series inverter as example to introduce the connection in this manual.

When SECU-A5.4L is used with ES, EM, SBP and BP series inverters，the power cable needs to
be prepared by the user, the recommended conductor cross-sectional area is 25mm2.
· Before installation and cable connection, make sure the whole ESA cabinet is isolated from both
AC and DC power.
· The cables between the battery and the inverter are connected in the same way. Please refer to
the "Cable connection of SECU-A5.4L with ES, EM, SBP and BP inverters".

5.2 Powering on the battery system
Note: Please follow the instruction to turn on/off battery in case of any damage on battery modules.
In battery enclosure, battery cable and communication cable is preset
inside. Connect directly these cables on battery to the right position:
Note:
1. The two COM ports on battery are of the same function.
2. Battery packs shall be connected in parallel.
3. The cables between the battery and the inverter are connected in
the same way. Please refer to the "Cable connection of
SECU-A5.4L with ES, EM, SBP and BP inverters".

5.1 Calibrating the DIP switch
• The DIP switches shall be configured differently between single piece battery and 2 battery
paralleling system.
• We just take SBP series inverter systerm as an example, the calibration method of the DIP
switch for ESA series inverter systerm is the same.

8. Safety Instructions
The system has been designed and tested under international safety requirements. However, to
prevent personal injury and property damage and ensure long-term operation of the system, do
read this section carefully and observe all safety information at all times.
Battery Module Leakage
If the battery modules leak electrolyte, please avoid contact the leaking liquid or gas. If one is
exposed to the leaked substance, do these actions:
Inhalation: Evacuate the contaminated area, and seek for medical help immediately.
Eye contact: Rinse your eyes with clean water for at least 15 minutes and seek for medical help
immediately.
Skin contact: Wash the affected area thoroughly with soap and clean water, and seek for medical
help immediately.
Ingestion: Induce vomiting, and seek for medical help immediately.
Firefighting Measures
• In case of a fire, please make sure that a carbon dioxide extinguisher or Novac1230 or FM-200 is
nearby. Water cannot be used to extinguish the fire. (ABC is not effective for this battery firefight-
ing)
• Full protective clothing and self-contained breathing apparatus are required for the firefighters to
extinguish the fire.
Warning: Under >150℃environment, there is possibility that battery could explode
Handling and Storage Guide
• The battery modules and its components shall be protected from damage when it is in transporting
and handling
• Please take the weight of the battery module system into account during transportation and battery
module shall be lifted carefully
• Do not impact, pull, drag or step on the battery modules, either insert unrelated objects into any
part of the battery modules
• The battery module shall be kept away from a fire, water, strong oxidizers or solvents
• The battery modules cannot be stored in high temperature (> 60℃) or stored directly under the
sun, or in any high humidity environment.
• Do not use the battery modules if it is defective, or appears cracked, broken.
• Do not attempt to open, disassemble, repair, tamper with, or modify the battery modules without
official permission from GoodWe.
Warning: battery module damage may lead to electrolyte explosive air leakage, please
contact technical support immediately.

Warning of Electric Shock
It is danger to get electric shock when live components or DC cables are touched.
Disconnect the battery from voltage source before working on the device. Make sure of no any
manual operation under load. And do not touch non-insulated parts or cables. And wear suitable
protective equipment for all work on the system.
Warning: If battery is wetted, make sure it is not touched by hand, and contact technical
support
Surge Protection
Over voltages can be further conducted into the building or other connected devices in the same
network via network cables or other cables if there is no surge protection.
Ensure that the system is integrated into the existing surge protection.
