Champion Lakes Battery Storage Upgrade

We recently delivered a major energy storage upgrade for a homeowner in Champion Lakes. The property already had a functioning solar system, but like many WA households, they were exporting excess power to the grid during the day and still paying high tariffs to buy electricity back each evening.

To solve that, we installed a high-capacity battery storage system designed to capture daytime solar production and make it available for night-time use. The result is significantly lower electricity bills, more control over household energy, and long-term protection from rising power costs.

System Overview

This home battery upgrade includes:

• 5 kW Alpha ESS Hybrid Inverter
• 4 Alpha ESS 5 kWh batteries, totalling 20 kWh of storage
• Blackout protection for full-home backup of essential circuits

The system has been AC-coupled to the client’s existing solar installation. This ensures smooth system integration without replacing hardware that is still performing well.

Why This System Was Chosen

The Alpha ESS Hybrid Inverter delivers smart energy management across both the solar and battery systems. It prioritises solar power for household use first and then charges the batteries with any surplus generation. Only once the battery is full does excess energy export to the grid.

The 20 kWh battery capacity offers substantial stored power, allowing the homeowner to:

• Run the home efficiently after sunset
• Reduce grid-purchased power to a minimum
• Offset peak electricity prices during high-tariff hours
• Improve return on investment from their existing solar array

This is particularly effective in seasons with high air-conditioning usage, common in WA.

Blackout Protection and Energy Security

Through the integrated backup system, essential circuits remain powered during grid outages. The changeover happens quickly and automatically, keeping important household systems operating without disruption.

This protection has become a major priority for many families due to weather-related outages and growing pressure on the grid.

Financial and Lifestyle Benefits

This upgrade supports strong financial outcomes by:

• Maximising the value of solar generation
• Reducing electricity bills throughout the year
• Avoiding bill shocks caused by moving tariff structures
• Providing resilience against future price increases

Beyond savings, it also delivers peace of mind, increased property value and a more sustainable day-to-day lifestyle.

Future-Ready Investment

The installation is modular and scalable, meaning battery capacity can be expanded if household electricity usage increases over time. This flexibility makes Alpha ESS a strong long-term investment as consumer energy needs evolve.
