PACKING LIST

The items listed below will arrive with the product shipment:
EG4 WallMount All Weather

*The mounting bracket will arrive attached to the back of the battery

LOCATION SELECTION AND INSTALLATION
Requirements for installation location:

• The WallMount is heavy. Use a lift or other equipment to lift and carry the unit.
• The battery can be installed on either flat ground or on the wall. If installing on flat ground, ensure there is proper drainage on the ground surrounding the battery to maintain integrity of the module over time. If installing on the wall, ensure at least a 12 in. gap on each side of the unit for adequate airflow and operations.
• Install the battery in a location that prevents damage from flooding.
• Ensure the battery is mounted upright.
• The battery must be installed with at least 12 in. of clearance on all sides of the unit.

NOTE: The battery will be shipped with temporary lifting handles for removing the battery from its packaging. The battery is very heavy. Use the team-lift technique during installation and remove the temporary lifting handles before making any connections within the system.

PRE-WIRE STEPS AND WIRING

Refer to the table below for wire size and torque recommendations for the battery cables.

IMPORTANT
The battery is capable of charging/discharging up to 200A before the BMS shuts off the pack. Ensure the inverter is configured to handle this high of a current, and size all wires accordingly! Refer to an NEC approved ampacity chart or consult with the installer or a solar electrician for more information.

MULTIPLE BATTERY PARALLEL INSTALL
When paralleling multiple WallMount All Weather batteries, an optional paralleling kit must be purchased through the distributor.

NOTE: When installing multiple batteries or adding a battery to an existing rack, please ensure all batteries are charged to 100% before paralleling together. This step is crucial to optimize battery performance and ensure proper operation.
Follow the steps outlined below to ensure proper installation of multiple batteries in parallel.

1. Ensure all circuit breakers are open (off). Using a multimeter, check for voltage at all available disconnects and lines. Once no voltage is confirmed, proceed to the next step.
2. Set the DIP switch address on the master battery to address 1, and all other batteries in parallel to differing addresses going in ascending order. (See image)
3. Reset the battery BMS via the power button to register the address change.
4. Set up communication between the batteries via the “Battery-Com” ports by using a CAT 5, 5e, or 6 cable. Refer to the image below for an example.
5. The battery set to address 1 will connect directly to the inverter BMS communication port via CAT 5, 5e or CAT 6 cable.
6. Install battery paralleling cables between the batteries included in the optional paralleling kit ensuring the connectors are seated properly.

MULTIMETER TESTING AND WIRING
Follow the steps outlined below to both test the inputs and wire the battery pack to the inverter.

1. Ensure all circuit breakers are open (off). Using a multimeter, check for voltage at all available disconnects and lines. Once no voltage is confirmed, proceed to the next step.

2. Connect the included sets of 2/0 AWG (70mm2) with outdoor rated connectors to the battery’s positive and negative terminals. The connectors will “click” when seated properly.
   NOTE: If installing the battery pack with the optional conduit box, secure the conduit fittings to the enclosure using the counter nuts after step

4. If applicable, route the battery power cables through the conduit box to the inverter without making any connections!
   DANGER!
   No connections should be made until proper polarity of cables has been confirmed!

5. Ensure proper polarity of cables. Once confirmed, proceed to the next step.

6. Install the 2 positive battery cables to the inverter’s positive battery terminals following proper torque values.

7. Install the 2 negative battery cables to the inverter’s negative battery terminals following proper torque values.

BMS COMMUNICATIONS

cable or a standard CAT 5, 5e, or 6 cable for closed loop communications with supported EG4 and non-EG4 inverters using CAN bus protocol. The PC software “BMS TOOLS” provides real-time battery analysis and diagnostics. The battery cannot communicate with the software and a closed loop inverter simultaneously. Scan the QR code for a white sheet walking through the BMS Tools setup process.

CLOSED LOOP COMMUNICATIONS

1. Power off all battery DC breakers and BMS power buttons.
2. The inverter protocol can only be changed with the master battery temporarily set to address 64 (all switches ON). After the DIP switch is changed, restart the BMS using the BMS power button for the settings to take effect. (See image)
3. On the master battery, press and hold the “Return”  key for 5 seconds and release to enter the “Protocol Setting” menu.
4. Select the corresponding CAN protocol (P01-EG4/LUX) for the system if using EG4 inverters,(See table below).
5. Change the master DIP switch address back to address 1 for inverter communications & power cycle the BMS. (See image)

The tables below show compatibility lists depending on the type of communication protocol used for closed-loop communications between battery and inverter.
