Page 10: Installation Steps
 This battery pack weighs about 61kg. To prevent personal injury, it is recommended to use proper lifting equipment during installation.  If the user notices any deformation of the battery pack shell during installation, they should stop the installation process and contact us immediately. ...
Page 11 1. Structure Installation 1) Install wall mounting bracket The MAPLELEAF POWERWALL series battery is designed to be wall-mounted during installation. The rack should be fixed onto the wall using anchor screws. For information on the weight and dimensions of the MAPLELEAF Lithium Battery, please refer to the product's data sheet. 2) Installation battery pack a) a) Use two people to lift the battery out of the wooden case.
Page 12 2. Cable Connection 1) Connecting the battery The battery terminals are located at the bottom of the front cover. Please ensure that the breaker on the right side of the rack is in the OFF position. Install the positive cable first and then the negative cable.
Page 13 2) Communication Port MAPLELEAF POWERWALL series battery has a self-managed Battery Management System (BMS). The Communication board has three ports which are designed to support Inverter RS 485 and CAN communication, battery parallel communication (see Parallel Connection). When batteries need to communicate in parallel, the user needs to set the battery address through the DIP switch, and the CAN communication port of the last battery needs to connect to the terminal resistor.
Page 14 4) Parallel Connection The following illustration shows how to connect multiple batteries in parallel. Please follow the procedure to parallel POWERWALL series batteries: Prepare communication cable. Each unit comes with 1pcs RJ45 cable (for inter- battery Parallel CAN port). Cables for communicating with the inverter are provided by the customer. If the cable is missing, please make sure the cable you purchase on the market meets the following standards.
Page 15 Confirm the Battery DC breaker is in the “OFF” position. Wire each battery’s Power bus to Inverter. And wire inverter’s cable to PV, Grid and Load. Use the RJ45 cables to connect the batteries’ Parallel CAN port, as illustrated in the chart below. Ensure that the communication port of the last terminal (N) is connected to 120Ω...

Dial Switch Module number Single module Parallel mode(Master) Parallel mode(Slave) Parallel mode(Slave) Parallel mode(Slave) Parallel mode(Slave) Parallel mode(Slave)
Page 17 NOTE!  If used for single battery without parallel, must set Address as 0.  When used for several batteries parallel, please set the master battery number as 1, and the other battery number as 2~14. 7) Touch the Upper computer to set Inverter as the following form. Inverter Setup Support Inverter Protocol Schneider Modbus, 19200bps...
Page 18 As the battery voltage increase by inverter, other battery join in to parallel one by one. After all normal batteries complete parallel, the parallel process end up, and recover normal request from inverter. 3. Wire the battery cables For connecting multiple units: Maintain the recommended distance among battery units’s side or wall- at least 12inches (300mm).
Page 19: Operation
4. System Commission If you only install single POWERWALL series battery, please follow the below steps to start up: a) Check system connection cables for correct polarity. b) Put the battery’s breaker on the “ON” position. c) Put inverter breaker in the “ON” position. d) Push the power button on the front of the unit for 3 seconds to turn on the battery LCD display.
Page 20: Discharging
5.3 Discharging  Do not discharge battery below operating voltage.  Do not discharge battery at rates greater than maximum continuous current.  Do not operate in conditions that will exceed the internal operating temperatures of the battery. 5.4 Parameter set up guide in Charger/Inverter Before commissioning the energy storage system, the appropriate controller and inverter settings must be programmed per the manufacturer’s recommendations.
