Key Advantages
Smart Charge & Discharge Scheduling
Set charging and discharging times around local peak and off-peak electricity periods. This helps households use lower-cost energy more effectively and reduce reliance on the grid during expensive peak hours.
Compliance for Market Access and Transport
CE, RoHS, UKCA, G99 and MSDS documentation support key requirements across product compliance, grid connection and transportation—helping distributors and installers enter target markets with greater confidence.
Modular, Stackable Design
Start with the capacity you need and expand as energy demand grows. The stackable battery modules enable flexible system configuration from 5.12 to 30.72 kWh.
Multi-Layer Battery Safety
Thermally stable LiFePO₄ battery chemistry, intelligent BMS protection and a built-in fire detection and early-warning module provide multiple layers of protection for reliable residential operation.
10-Year Battery Warranty
A 10-year battery warranty provides long-term product assurance and greater confidence for homeowners, installers and distribution partners.
Is Terra B the Right System for Your Project?
Time-of-Use Energy Savings
Charge the battery during off-peak hours and use stored energy when electricity rates are higher, helping reduce household energy costs.
Solar Energy Storage
Store excess solar energy generated during the day and use it to power the home in the evening or at night.
Extended Backup Power
Provide longer-lasting backup power for essential household loads during grid outages or extended off-grid periods.
Flexible Future Expansion
Start with the capacity you need today and add battery modules later as household energy demand grows.
Space-Saving All-in-One Design
The integrated battery and inverter design requires less installation space, simplifies system setup and reduces installation complexity.
Homes and Small Businesses
Suitable for residential properties and small commercial premises such as guesthouses, cafés and flower shops.
How Terra B Works
Energy Management in Action
Daytime Solar Storage → Use later instead of exporting to grid
Nighttime Off-Peak Charging → Lower electricity costs
Peak Hour Deployment → Reduce bills and reliance on fossil fuel electricity
Backup During Outages → Essential circuits remain powered
Save Money. Save Energy. Stay in Control.
A modular, smart, and safe home battery system that helps households reduce electricity costs, integrate solar energy, and provide reliable backup power when needed.
UK Compliance & Installation Notes
For UK residential applications, Terra B system design, modular battery configuration, installation location, wiring, backup configuration, grid connection, export limitation or non-export operation must be assessed and implemented by qualified professionals in accordance with applicable UK electrical regulations, ENA Engineering Recommendations such as G98/G99 where applicable, DNO requirements, GeePower’s official installation guidance, and the requirements of compatible inverter and protection equipment.
The final system capacity, backup availability, automatic switching, critical-load support and energy-cost optimisation depend on the selected configuration, site conditions, approved connection method, compatible equipment and qualified installation.
