How hybrid battery solar systems work
ESSENTIALS OF HYBRID BATTERY SOLAR SYSTEMS
A hybrid battery solar system combines solar production and storage, ensuring a steady power supply even during outages or low sunlight. Each component plays a key role in making this a highly efficient and reliable clean energy solution.
SOLAR PANELS
Efficient Solar Capture
In a hybrid system, solar panels power both your home and battery, capturing sunlight efficiently and converting it into direct current (DC) electricity. Built for durability and high performance, our panels ensure a steady energy supply for immediate use and storage, meeting both current and future needs with reliable efficiency.
Solar Inverter
Streamlined Energy Flow
The hybrid system’s inverter converts DC power from the panels into alternating current (AC) for home use while managing energy flow to both your home and battery. Our inverters adapt to changing energy needs, ensuring smooth, precise power conversion that supports both self-sufficiency and efficient system performance.
The Grid
Flexibility Meets Savings
Integrating with the grid adds flexibility to your hybrid system. Access power when you need it and export surplus energy back to the grid, earning credits. Our systems are designed for seamless, efficient grid interaction, providing balanced energy management that adapts to your needs.
Why choose a hybrid battery solar system
VERSATILE, SECURE ENERGY FOR YOUR HOME
A hybrid battery system offers grid reliability with solar independence. Ideal for those seeking backup assurance and cost savings, it ensures power even when the grid is unstable—providing both economic and environmental benefits.

Advantages
Uninterrupted power
Automatically powers essential appliances like refrigerators and lights during outages, ensuring critical functions continue.
Maximised energy use
Stores surplus solar energy for nighttime and cloudy days, boosting efficiency and lowering utility costs.
Reduced grid dependence
Significantly lowers reliance on utility power by generating and storing energy, leading to long-term bill savings.
Considerations
Higher initial investment
Adding batteries raises upfront costs but increases energy independence and provides additional savings over time.
Essential loads only
Prioritises power for essential appliances during outages; system capacity should match critical energy needs.

Find out what AFFECTS the cost of your Hybrid Battery system
Energy needs
System size typically scales with consumption levels, directly affecting cost.
Battery capacity
Chosen based on usage patterns, the battery size is a key investment factor.
Components quality
High-grade panels, inverters, and batteries impact cost and long-term reliability.
Install complexity
Cost is influenced by roofing, site specifics, wiring needs, and scaffolding.
Energy goals
Grid independence or substantial energy savings goals necessitate a larger system.
Tech upgrades
Smart tech and EV charging integration increase both efficiency and initial cost.
Custom solutions
Personalised energy systems for unique requirements (e.g. smart homes) alter the financial outlay.
Hybrid battery solar system case study
Cost Savings And Energy Impact
With an investment of $24,307 (including GST), these homeowners installed a 5.28kW hybrid battery solar system featuring 12 LONGi 440W Black Frame panels, a RedBack SH5000 5.0kW Hybrid Inverter, and two PylonTech 3.55 kWh lithium-ion batteries. This setup targeted 80% self-consumption, achieving significant savings.
Their average monthly electricity bill dropped from $242 to $59.92—a 75.24% reduction. Over 25 years, this equates to $77,550.75 in total savings, factoring in rising utility costs and income from selling excess electricity. Environmentally, the system’s impact is equivalent to the CO₂ absorption of 40 trees and powers 528 light bulbs continuously.
