Battery Storage FAQs

How do home batteries perform during Wollongong storms?
Home batteries can provide backup power during outages, though the duration depends on your battery size and what appliances you're running. Most systems can keep essentials like lights, fridge and wifi running for several hours to overnight.
What battery size suits typical Illawarra homes?
Most families in the Illawarra use 15-25kWh daily, so popular battery sizes range from 10-20kWh. Starting with one battery and adding more later is often more practical than oversizing initially, especially with modular systems.
How do I know if a home battery is worth it for my home?
If your energy usage is high in the evenings, you're looking for some energy security in case of blackouts, or you're looking to reduce your grid dependence and power bills – a home battery can help. We provide tailored, free on-site assessments to determine if it's the right fit based on your usage, roof space and budget.
How much energy can a battery store?
Storage capacity varies by model, typically ranging from 5 kWh to 13.5 kWh per unit, with options to stack multiple units for larger homes. We'll recommend the best option during your assessment.
Can I add a battery to my existing solar system?
Yes, most existing solar systems can be upgraded with a Tesla Powerwall 3, Enphase, GoodWe, or SolarEdge battery. We can explore your options during your free consultation and in-home assessment.
What happens during a blackout?
With a solar battery and the right inverter setup, your home can continue operating during grid outages, keeping essential appliances running and your family comfortable. Tesla Powerwall 3, Enphase, and SolarEdge all offer seamless backup capabilities.
How long do batteries last?
Modern lithium batteries are designed to last 10-15 years with minimal degradation. All our battery products come with comprehensive warranties – Tesla offers 10 years, Enphase offers 15 years, GoodWe offers 10 years, and SolarEdge offers 10 years.
Are there government rebates for batteries?
QLD residents may be eligible for state-specific battery rebates in addition to federal incentives. We handle all the paperwork to ensure you claim everything you're entitled to.
