System Overview

The Stackable Battery System is designed to simplify installation, improve scalability, and reduce cabling complexity. A base unit contains the primary BMS interface, while additional battery modules stack vertically to expand storage capacity. Communication and power connections are integrated into the stacking system for streamlined assembly.

• Integrated base with BMS and communication hub
• Stacking rails and locking clamps for secure alignment
• Support for multiple stacked battery modules
• Compatible with GivEnergy Hybrid and AC Coupled inverters (Gen 3 range)

Safety Information

• Install on a level, load-bearing floor capable of supporting stacked modules.
• Only lift modules using appropriate technique or assistance — modules are heavy.
• Ensure the installation location is dry, well-ventilated, and not exposed to direct sunlight or frost.
• Do not stack modules on uneven or unstable surfaces.
• Isolate DC and AC power before installing or adding modules.

Components

• Base Unit — houses the main BMS, connection ports, and support frame.
• Stackable Battery Modules — 5.12 kWh or 9.5 kWh Gen 3-compatible units.
• Side Panels / Covers — used to enclose multi-module stacks.
• Stacking Rails and Alignment Pins — ensure safe, precise stacking.
• DC Cable Set — connects the base unit to the inverter.

Installation Requirements

• Indoor installation only.
• Floor mounting only — wall mounting is not supported for this system.
• Minimum clearance must be maintained around the assembly for cooling and access.
• The floor must be flat to prevent tilt or battery misalignment.
• Avoid installing near corrosive substances, vibrations, or direct heat sources.

Stacking Procedure

1. Ensure the base unit is positioned on a flat, stable surface.
2. Align the first battery module with the base unit using the built-in pins.
3. Lower the module until it locks securely into place.
4. Repeat for each additional module, ensuring each level is fully seated.
5. Install side panels or protective covers as required once the final height is reached.

The design eliminates the need for additional wiring between modules — electrical and communication pathways connect automatically when stacked.

Electrical Connections

• DC cables connect from the base unit directly to the inverter.
• CAN communication cabling is integrated internally — no daisy-chaining required.
• Ensure correct polarity before energising the system.
• Installers must verify torque settings on DC terminals.

LED Indicators

LEDs on the base module and/or battery modules provide system status:

• Green: Normal operation
• Blue: Charging
• Yellow: Idle or limited activity
• Red: Fault detected — check inverter or portal

Commissioning Procedure

1. Verify all modules are fully locked into place.
2. Ensure all cables are properly routed and strain-relieved.
3. Turn on the battery isolator.
4. Power on the inverter.
5. Confirm battery stack detection in the GivEnergy portal or app.
6. Verify no alarms or abnormal LED signals are present.

Maintenance

• Keep dust and debris away from ventilation areas.
• Inspect mechanical locking points annually.
• Check for firmware updates via the inverter periodically.
• Ensure the floor remains level and vibration-free.
• Do not store objects on top of the battery stack.

When to Contact Support

• Unexpected LED behaviour (red or alternating colours)
• Modules not detected or showing incorrect capacity
• Heat, swelling, or unusual noises from any module
• Repeated communication faults in the inverter portal

If issues persist, contact your installer or GivEnergy Support with your system serial number, firmware versions, and photos of the battery stack.
