GivEnergy 3.4kWh HV Battery Module: The Scalable Energy Storage Solution for High-Demand Systems

The GivEnergy 3.4kWh HV battery module is engineered for flexibility and performance in larger residential and commercial systems. Its stackable form factor and high-voltage compatibility allow it to be built into multi-unit storage banks tailored to your project’s size and power requirements.

Whether you're expanding an existing system or designing a new build, this module delivers reliable lithium iron phosphate (LiFePO₄) performance and long-term cycling efficiency in a clean, compact casing.

Modular Scalability with High-Voltage Efficiency

This battery is designed to be stacked vertically in sets of 2 to 5 modules alongside a Battery Management Unit (BMU), offering total storage from 6.8kWh to 17kWh per stack. The system can be scaled even further using parallel stack configurations.

• Stack 2–5 modules per tower with a BMU
• Up to 6 towers in parallel for larger installations
• Ideal for high-usage homes, commercial units, or EV charging integration

Space-Saving Format, Built for Easy Integration

With its vertical design and slim profile, the 3.4kWh HV module fits into tight plant rooms or garages. It’s easy to handle during installation and comes with integrated connectors for quick setup.

• Each module measures 480 x 443 x 130mm
• Efficient footprint for clean energy storage layouts
• Works seamlessly with GivEnergy’s HV hybrid inverters

Advanced Battery Chemistry for Long-Term Use

The unit uses LiFePO₄ cells for enhanced thermal stability, safety, and cycle life. With a lifespan exceeding 6,000 cycles at 90% depth of discharge, this battery is a long-term investment in energy resilience and reduced bills.

Compatible with GivEnergy HV Systems

This module is designed specifically to work with GivEnergy’s high-voltage inverters and the dedicated HV Battery Management Unit (BMU). It integrates seamlessly into existing GivEnergy setups, supporting smart control, solar pairing, and energy tariff optimisation.

• Pair with 11kW or 20kW GivEnergy HV hybrid inverters
• Smart system monitoring via GivEnergy portal
• BMU enables safe and intelligent balancing across all cells
