Project Overview
Harrington Grove is known for its high-quality residential standards, and our client’s home was no exception. Already equipped with a solar array, the homeowner wanted to move to the next level: total energy self-sufficiency. Their primary concern was finding a local partner with a proven track record for workmanship and reliable after-sales support to handle a high-capacity battery integration.
What the client needed
- Energy Independence: To store daytime solar production for use during peak evening periods and overnight.
- A Trusted Local Supplier: A provider with verified reviews and specialized experience in high-voltage 3-phase systems.
- Significant Cost Reduction: A system sized appropriately to target a “near-zero” electricity bill.
Our objectives
- Seamless 3-Phase Integration: Ensure the new battery and inverter worked harmoniously with the existing home infrastructure.
- Maximize Storage Capacity: Provide enough capacity (20kWh) to cover high-load appliances and ducted air conditioning common in the area.
- Future-Proof Performance: Utilize the latest LFP (Lithium Iron Phosphate) chemistry for maximum safety and longevity.
Provided Solutions
We installed the Sungrow SBH 20kWh Battery Storage System paired with a 5kW Sungrow 3-Phase Hybrid Inverter. The SBH series was selected for its modular, stackable design, which allows for a clean, space-efficient installation. As a 3-phase property, this specific Sungrow combination ensures that backup power and solar consumption are balanced across the entire home, rather than just a single circuit.
Final Outcome
The result is a highly efficient “self-charging” home. With 20kWh of storage, the client now captures enough energy during the day to power the house through the entire night. By eliminating the need to purchase power during peak utility windows, the homeowner has significantly increased their ROI and is on track to achieve $0 electricity bills for the majority of the year. The client expressed high satisfaction with the tidy installation and the peace of mind that comes with a premium 10-year warranty.
