Quick-Start Guide for EG4 WallMount All Weather Battery

Quick Start Guide

This document provides essential instructions for the installation and setup of the EG4 WallMount All Weather battery. Always ensure all system components are up to date and follow local electrical codes.

Safety Precautions

Working with high-voltage battery systems carries risks. Follow these critical safety measures:

• High Voltage Warning: Always use a voltmeter to confirm there is no DC or AC voltage present before working on the battery.
• Disconnects: Ensure all external DC disconnect switches, AC breakers, and battery module breakers are in the "off" or "open" position before installation.
• PPE: Installers must use professional insulative equipment (PPE).
• Connections: Do not make or break any connections (PV, battery, grid, communication) while the battery is operating.
• Grounding: Ensure the battery is properly grounded according to NEC (ANSI/NFPA 70) standards.

Installation Requirements

The WallMount battery is heavy and requires careful handling.

• Lifting: Use a lift or team-lift technique. Remove temporary lifting handles before making connections.
• Clearance: Maintain at least 12 inches of clearance on all sides of the unit for airflow.
• Mounting Height: If wall-mounting, ensure a minimum clearance of 28.0625 inches from the ground.
• Environment: Install in a location that prevents flooding. If installing on flat ground, ensure proper drainage.

Mounting the Battery

The battery can be installed standalone, with a conduit box, or integrated with an 18kPV inverter.

• Standalone: Remove the mounting bracket from the battery, secure it to the wall using a level and expansion bolts, hook the battery onto the bracket, and secure it with the 4 side screws.
• Conduit Box: Follow the same mounting procedure, then attach the optional conduit box to the top of the battery using the included hardware.
• 18kPV Integration: Use the provided X-bracket behind the mounting plate. Ensure the inverter's bottom knockouts align with the conduit box.

Wiring and Connections

Refer to the following guidelines for cable sizing and torque:

• 1/0 AWG (53.5 mm²): Max 10 ft. distance, 165 in-lbs (18.6 Nm) torque.
• 2/0 AWG (67.4 mm²): Max 20 ft. distance, 165 in-lbs (18.6 Nm) torque.
• 4/0 AWG (107 mm²): Max 10 ft. distance, 275 in-lbs (31.1 Nm) torque.
• 250 kcmil (127 mm²): Max 20 ft. distance, 275 in-lbs (31.1 Nm) torque.

Important: Ensure proper polarity before making connections. The battery is capable of 200A discharge; ensure the inverter is configured to handle this current.

Parallel Installation

To install multiple batteries in parallel:

1. Ensure all breakers are off and verify zero voltage with a multimeter.
2. Set the DIP switch address on the master battery to 1. Set other batteries to ascending addresses.
3. Reset the BMS via the power button to register the address change.
4. Connect batteries using CAT 5, 5e, or 6 cables via the "Battery-Com" ports.
5. Connect the master battery (ID 1) directly to the inverter BMS port.

BMS Communications

The battery interfaces with compatible inverters via RS485 or CAN bus protocol. To change the inverter protocol:

1. Power off DC breakers and BMS.
2. Set the master battery DIP switch to address 64 (all switches ON).
3. Restart the BMS, hold the "Return" key for 5 seconds to enter the "Protocol Setting" menu.
4. Select the appropriate CAN/RS485 protocol for your inverter.
5. Reset the master DIP switch to address 1 and power cycle the BMS.
