Product Overview

[1]: Only for SECU-A5.4L.
Note :
The two COM ports on battery are of the same function.
The two Power Cable Connector + or – on battery are of the same function.

Cable Connection

Power Cable Connection

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 battery 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.

Power cable connection of battery with ES, EM, SBP and BP inverters

When battery 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.

Power cable connection of battery with ESA inverter

• 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 battery with ES, EM, SBP and BP inverters”.
• Open battery enclosure and install batteries and other component by sequence as below:

Communication Cable Connection

Communication cable connection of battery with ES, EM, SBP and BP inverters

When battery is used with ES, EM, SBP and BP series inverters the network cable needs to be prepared by the user.

RJ45 connector

Communication cable connection of battery with ESA inverter

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 battery with ES, EM, SBP and BP inverters”.

Battery Commissioning

Calibrating the DIP switch(SECU-A5.4L)

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

Setting the parameters of battery On PV Master app

To make sure the battery communicates to inverter unit successfully, users have to use PV Master to choose the right battery option on PV Master:

APP Installation And Connection:

Download and install PV Master|
---|---

Select Battery on PV master

Select “SECU-A5.4L” or “SECU A5.4-20”on battery page in PV Master Application

Notes:

1. Select wrong battery will lead to BMS communication failure
2. Select wrong number of batteries the input and output current will be limited and the parameter indicated by the inverter is inconsistent with the actual value of the battery.
3. For the complete commissioning of the whole ESA system, please go to ESA instruction.

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 firefighting)
• 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 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.
