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.​​​

Why Terra A-Series?

You don’t need solar to save money

Charge your battery from the grid during off-peak periods and use stored energy at peak times to lower your bills.

Smart energy management

Schedule charging and discharging via the integrated inverter interface. Store energy when electricity is cheap and deploy it when prices are high.

Backup power & reliability

Protect your home from outages and price spikes. The system ensures critical loads stay powered while keeping costs down.

Flexible & scalable

Modular design allows capacity expansion from 5 kWh to 30 kWh as your energy needs grow. Works with or without solar panels.

Safe & sustainable

Thermally stable LiFePO4 battery with built-in fire suppression. Designed for long-term reliability and environmental responsibility.​


Benefits for Homes

  • Save on electricity bills by charging during low-cost off-peak periods.
  • Reduce reliance on grid electricity and maximise use of home-generated solar energy.
  • Reliable backup during outages ensures essential loads stay powered.
  • Safe indoor installation thanks to thermally stable batteries and integrated fire suppression.
  • Scalable solution to grow with your household energy requirements.

Explore the Terra A-Series

Whether you need 5 kWh for a small home or 30 kWh for a large household, Terra A-Series can be configured to meet your energy needs. Its modular, stackable design ensures future expansion without disruption.

​



How It Works

Grid Charging – Automatically charges during off-peak electricity periods.

Load Supply – Powers household loads during peak-demand periods or high tariffs.

Backup Mode – Supplies essential circuits during grid outages.

Optional Solar Integration – Solar energy can supply loads directly or charge the battery.

Energy Scheduling – Configure charge/discharge settings via the inverter LCD for maximum efficiency.


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
