IMPORTANT: The battery can charge/discharge up to 200A before the BMS shuts off. Ensure the inverter handles this current and wires are sized accordingly. Refer to NEC approved ampacity charts or consult an installer/electrician.

6.1 Multiple Battery Parallel Install

To parallel multiple WallMount All Weather batteries, an optional paralleling kit is required.

Ensure all circuit breakers are off. Use a multimeter to check for voltage at all disconnects and lines. Proceed only when no voltage is confirmed.
Set the DIP switch address on the master battery to address 1. Set other batteries to ascending, differing addresses. (See image of DIP switch).
Reset the battery BMS via the power button to register address changes.
Connect batteries using CAT 5, 5e, or 6 cables via the "Battery-Com" ports for communication. (See example diagram).
The battery set to address 1 connects directly to the inverter BMS communication port via CAT 5, 5e, or CAT 6 cable.
Install battery paralleling cables between batteries using the optional kit, ensuring connectors are seated properly.

Ensure all circuit breakers are off. Check for voltage at all disconnects and lines with a multimeter. Proceed when no voltage is confirmed.
Connect the included 2/0 AWG (70mm²) cables with outdoor-rated connectors to the battery's positive and negative terminals. Connectors will "click" when seated properly.

Note: If using the optional conduit box, secure conduit fittings with counter nuts after step 2.

If applicable, route battery power cables through the conduit box to the inverter without making connections.

DANGER! No connections should be made until proper polarity of cables has been confirmed!

Ensure proper cable polarity.
Install the 2 positive battery cables to the inverter's positive terminals, following proper torque values.
Install the 2 negative battery cables to the inverter's negative terminals, following proper torque values.

7. BMS Communications

EG4 batteries interface with compatible inverters by designating a "Master" battery (DIP switch ID No. 1).

The battery connects directly to the inverter via an RS485 or 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 guide on the BMS Tools setup process.
