The GivEnergy All In One 2 Expansion Battery (13.5 kWh) is designed to extend the storage capacity of the All In One 2 system, enabling greater energy independence for medium to large homes. With seamless system integration and intelligent energy management, this expansion battery allows users to store more renewable energy and reduce reliance on the grid.

Built for scalability and long-term performance, the expansion battery supports whole-house energy strategies, flexible tariffs, and future grid services participation.

Scalable Energy Storage for Greater Independence

Adding the 13.5 kWh expansion battery increases total usable storage, allowing households to maximise self-consumption of solar energy and maintain power availability during high-demand periods. The modular design ensures simple system expansion without compromising performance or reliability.

Whole-House Backup Capability

When paired with the All In One 2 Gateway, the system provides whole-house backup power, acting as an uninterruptible power supply (UPS) during grid outages. This enables off-grid operation until grid supply is restored, keeping essential and non-essential loads running seamlessly.

Important:
Whole-house backup functionality requires the GIV-AIO2-GATEWAY2.

Grid Services & Smart Tariff Optimisation

The expansion battery is grid services ready, enabling participation in energy supplier and aggregator programmes that reward users for reducing or shifting electricity usage during peak demand periods.

Through flexible rate tariff optimisation, the battery can:

• Charge during off-peak periods when electricity is cheaper and cleaner

• Discharge during peak times to maximise savings and reduce grid dependency

This intelligent charging strategy supports both cost reduction and grid stability.

System Weights & Component Breakdown

• All In One 2 with batteries: 181.3 kg

• All In One 2 without batteries: 56.5 kg

• Individual battery pack: 31.2 kg (×4)

• MPPT box: 17.8 kg

• Expansion battery unit: 170 kg

These figures assist with installation planning and site preparation.

Installation & Gateway Requirements (Important Update)

Effective from 1 May 2024:

• The GIV-AIO-GATEWAY is only required for home backup functionality

• For installations without backup, the system must use GIV-GM120CT-P

• The CT is required only when installing without a gateway

Please ensure system design reflects the intended functionality prior to installation.

Warranty & Long-Term Assurance

• 15-year manufacturer warranty

This long warranty period reflects the durability, reliability, and lifecycle performance of the GivEnergy All In One 2 platform.

Ideal Applications

• Medium to large residential solar storage systems

• Homes seeking increased self-consumption and energy independence

• Properties using flexible or dynamic electricity tariffs

• Installations planning for future grid services participation
