How to Choose the Right Solar Battery for Your Home in Bendigo and Central Victoria

With rising electricity prices and growing demand for energy independence, more homeowners across Bendigo and Central Victoria are turning to solar battery storage systems to maximise their solar investment and protect against blackouts.

But with so many options on the market, how do you know which solar battery is right for your home?

In this guide, we’ll walk you through the key factors to consider when choosing the best home battery storage solution, whether you’re looking for backup power, bill savings, or full off-grid capability.

Solar batteries store excess electricity generated by your rooftop solar system during the day, so you can use it at night or when grid power is unavailable. This helps you:

• Use more of your own solar energy (rather than exporting it)
• Reduce your electricity bills
• Protect your home from power outages
• Move towards energy independence

In regional areas like Bendigo, where blackouts and voltage fluctuations are more common, a solar battery backup system offers both peace of mind and financial benefit.

Start by reviewing your average daily electricity consumption (in kWh). This helps determine the ideal solar battery capacity for your home.

• Small homes: 5–10 kWh
• Medium homes: 10–15 kWh
• Large homes or families: 15–20+ kWh

If you already have a solar system, check how much of your generated power is being exported to the grid—this is energy that could be stored and used instead.

Do you want to power just the essentials during a blackout (like your fridge, lights, and WiFi)? Or do you need whole-home backup?

• Partial backup systems are more affordable and common
• Whole-home backup batteries (like the Tesla Powerwall) can keep everything running but require larger capacity and investment

Discuss your backup priorities with your installer so your system is sized correctly.

Most modern batteries use lithium iron phosphate (LiFePO4) chemistry, known for safety, efficiency, and long lifespan.

At Sunergy Solar, we recommend trusted solar battery brands with proven performance in Australian conditions:

• Sungrow SBR Battery – Great value and modular expansion
• BYD Battery-Box – Flexible, scalable storage for future growth
• Tesla Powerwall 3 – Whole-home backup with smart controls
• Franklin Battery – Intelligent power management and backup
• PowerPlus Energy – Australian-made off-grid battery storage ideal for rural and remote homes

• On-grid batteries are best for homes connected to the electricity network and looking to reduce bills or gain blackout protection.
• Off-grid solar systems are ideal for rural properties or anyone wanting total independence. These systems require precise design to match your load profile and solar generation.

Sunergy Solar offers both options, including fully off-grid battery systems with PowerPlus Energy for regional homes across Central Victoria.

Make sure your battery is compatible with your existing solar inverter—or consider upgrading to a hybrid inverter that supports both solar and battery storage. Some batteries (like the Tesla Powerwall) include their own inverter, while others rely on third-party brands like Fronius or Sungrow.

Look for solar batteries with at least a 10-year warranty and a strong local support network. Cheaper batteries may seem appealing upfront but often have shorter lifespans or limited tech support.

At Sunergy Solar, we only install batteries from trusted manufacturers with proven track records and Australian-based support.
