Background

A remote agricultural site in Western Australia required a dependable and sustainable energy solution to power farm operations. The location had no access to the national grid, and diesel generators were expensive and unsustainable. The farm owner sought a high-capacity off-grid solar power station to supply reliable energy for equipment, irrigation, and residential use.

The Challenge
The system needed to:

Operate completely independent of the grid in a rural environment.

Power multiple loads — including pumps, cold storage, lighting, and domestic appliances.

Provide sufficient backup for multiple cloudy or rainy days.

Require low maintenance while ensuring high reliability and longevity.

The Solution
We designed and supplied a 32 kWh Off-Grid Solar Power System, combining efficient solar generation with advanced lithium battery storage.

Solar Array: 18 kW monocrystalline PV panels installed on both roof and ground mounts for optimized sun exposure.

Hybrid Off-Grid Inverter (15 kW): Smart inverter with integrated MPPT control and generator input for emergency backup.

 Battery Storage:48 V 640 Ah LiFePO₄ battery bank (≈ 32 kWh total capacity).Cycle life > 6,000 @ 80% DOD.

Built-in BMS for overcharge, temperature, and short-circuit protection.

Monitoring System: Real-time energy monitoring and remote diagnostics via mobile and web interface.

Results & Benefits

24/7 Energy Security: Fully powers the farm’s irrigation systems, cold storage, and housing facilities.

Eco-Friendly Operation: Reduced diesel consumption by > 90%, eliminating approximately 10 tons of CO₂ annually.

Long-Term Savings: Energy cost reduced by ~ 60%, with an estimated payback period of 5–6 years.

Scalable Design: Additional battery and solar capacity can be added to expand up to 50 kWh as needed.

Customer Feedback

“The off-grid system is the best investment we’ve made for our farm. It’s reliable, quiet, and completely independent. Even during cloudy days, we never lose power.”
