Sunshine Coast, QLD

ECG is the proud installer of an 18.45kW solar system and 48kWh Sigenergy battery storage solution on the Sunshine Coast.

When it came time to upgrade this Sunshine Coast home's energy system, the goal was to replace ageing equipment with a modern solution built around the needs of a busy four-bedroom household. ECG removed the original 20-year-old solar panels, existing inverter and solar hot water system, replacing them with a complete solar, battery and energy-efficient hot water upgrade.

The new system features 41 Trina Solar 450W panels paired with a 20.0kW Sigenergy three-phase energy controller and 48kWh of battery storage. To complete the upgrade, we also installed an iStore 18.4kW pool heat pump and an SPT Phantom All-in-One 270L heat pump hot water system, bringing together solar generation, battery storage and more energy-efficient ways to heat the pool and supply hot water.

Together, these technologies give the household greater control over how it generates and uses energy, a great example of how a well-designed home energy solution can go beyond solar, to meet the needs of the whole household.

Why Sigenergy?

We're big believers in making energy work smarter for homeowners, and Sigenergy brings solar conversion, battery storage and intelligent energy management together in one integrated system.

Instead of sending all excess solar power back to the grid, homeowners can store that energy in their battery and use it later, helping them get more out of the solar their system generates. The mySigen app also makes it easier to monitor system performance and energy use, giving homeowners a clearer picture of how their energy is working for them.

For this home, the 48kWh of battery storage is a real standout. With substantial capacity to complement the solar system, the household can store more of its excess solar generation for use when needed, helping reduce reliance on grid electricity.

Sigenergy's flexible system design also supports a range of compatible energy technologies, with options to adapt as household needs change. It's this combination of solar, storage and smart energy management that makes Sigenergy an exciting part of the solutions we deliver at ECG.
