26.6kWh Battery + 8kW Solis Inverter Home Battery System Solution

Yes, now is a great time to invest in solar energy in Australia. With generous federal subsidies like the Small-scale Renewable Energy Scheme (SRES) and the new Cheaper Home Batteries Program offering up to 30% off battery systems, households can significantly reduce upfront costs

Yes, solar energy storage systems can be fully customized to suit your household’s energy needs. Whether you require more than 50kWh for EV charging or less for basic backup, modular battery systems like Alpha allows flexible scaling. Under Australia’s Cheaper Home Batteries Program, eligible households can receive up to 30% off battery costs, making both large and small systems more affordable. With rising electricity prices and generous rebates, tailoring your solar-plus-storage setup ensures optimal savings and energy independence—especially for off-grid or high-consumption homes.

The primary consideration is your available solar power generation capacity. If your array is small, a 10kW inverter can help you make the most of idle periods or upcoming solar sharing periods. Larger arrays typically also require a 10kW inverter to avoid power generation limitations.

The reason why a 5kW inverter included in our $4999 Alpha ESS package is still suitable for many homes is that when solar output is strong, there is usually enough power generated throughout the day to keep the batteries fully charged without needing a larger inverter.

The main advantages of three-phase inverters are higher power output, more stable voltage, and higher efficiency, making them suitable for high-power applications; while single-phase inverters are cheaper and simpler in structure, making them suitable for homes and small systems.

If your home has three-phase electricity, it’s best to choose a three-phase inverter. When your appliances need power, the inverter will distribute the power evenly across the three phases. If you choose a single-phase inverter, the battery will only discharge from one phase, while your appliances require three-phase power, resulting in lower efficiency.

Maintaining a solar system in Australia is simple and cost-effective. For typical households, regular cleaning of solar panels every 6–12 months helps maximize efficiency, especially in dusty or coastal areas. It’s also important to check for shading from trees and inspect wiring for wear. Battery systems like Alpha requires minimal upkeep but benefit from annual health checks. Most inverters and monitoring apps alert users to faults automatically. With generous warranties and sunny conditions, Australian families enjoy reliable solar performance with very little maintenance.

Yes, our batteries are designed with safety as a top priority and meet Australia’s strict installation standards, including AS/NZS 5139 for battery storage. Systems like Alpha includes built-in Battery Management Systems (BMS) that monitor temperature, voltage, and charge levels to prevent overheating or overcharging.

In Australia, certified installers ensure proper placement, ventilation, and fire safety compliance. Most households opt for wall-mounted or outdoor-rated units with IP65 protection, making them safe even in coastal or high-heat environments. With professional installation and regular system checks, solar batteries are a reliable and secure energy solution.
