Case Study: 10 kW Sigenergy Solar + Battery System for Local Food Bank Volunteers

Project Overview

Level Electrical + Air Conditioning recently completed a high-performance solar and battery installation for a local couple who operate the community food bank. With constant refrigeration loads and a need for reliable, uninterrupted power, the clients wanted a system that would reduce running costs and ensure full backup capability during outages.

We designed and installed a premium Sigenergy solution that provides exceptional efficiency, resilience, and long-term value.

System Specifications

10 kW Sigenergy Single-Phase Hybrid Inverter – delivering high efficiency, smart load management, and seamless integration with the battery system.

Sigenergy 1-Phase Home Gateway – enabling whole-home backup with ultra-fast changeover in the event of a power cut.

1 × 8.0 kWh Sigenergy Battery – providing reliable stored energy to support the home’s essential loads, especially fridges and freezers.

32 × 440 W Suntech N-Type Solar Panels – a powerful 14.08 kW PV array using premium, high-efficiency modules for optimal generation across all seasons.

Clenergy Mounting System – durable and engineered for New Zealand conditions, ensuring long-term stability and safety.

Client Needs

The homeowners operate the town’s food bank from their property and rely heavily on multiple fridges and freezers to store donated goods. Their main goals were:

Reducing electricity costs associated with 24/7 refrigeration loads.

Ensuring full power continuity during outages so food supplies are never compromised.

Investing in a future-proof, intelligent energy system with reliable performance and monitoring.

Outcome & Benefits

1. Significant Energy Savings

The 14 kW solar array now offsets a large portion of the home’s daytime power usage, dramatically lowering the operational costs of running freezers and fridges.

2. Whole-Home Backup

With the Sigenergy Home Gateway and 8.0 kWh battery, the home seamlessly switches to backup mode during a power cut.

Essential appliances—particularly refrigeration—remain fully powered, protecting valuable food bank stock.

3. Smart Energy Management

The Sigenergy platform provides advanced monitoring, AI-optimised energy flow, and real-time insights, allowing the clients to clearly track their savings and usage patterns.

4. Long-Term Reliability

All components—including the N-Type Suntech panels and Clenergy mounting system—were selected for durability and efficiency, ensuring decades of trouble-free operation.

Conclusion

This project demonstrates how modern solar + battery technology can directly support community services. By combining high-efficiency Suntech panels with Sigenergy’s hybrid inverter and storage platform, Level Electrical + Air Conditioning delivered a system that not only reduces operational costs but also safeguards critical food storage in the event of an outage.

A reliable, resilient, and future-proof solution—purpose-built to support the great work this couple does for the local community.
