Solar battery upgrades for existing systems
If your energy needs have changed or your current battery no longer suits your home, we can assess your system and recommend safe, practical upgrade options.
Is it time to upgrade your battery?
Battery upgrades aren’t always about faults. Often they’re driven by changes in how a home uses energy.
An upgrade may be worth considering if:
- Your household energy use has increased
- Your existing battery capacity is no longer sufficient
- Your battery is nearing the end of its warranty
- You’re adding an EV charger or expanding your solar system
- You want improved or more flexible backup capability
We’ll help confirm whether upgrading makes sense, or whether your current system is still fit for purpose.
Clear advice, not upselling
Battery upgrades need careful compatibility checks to avoid wasted cost or unreliable performance.
Our approach includes:
- Assessment of your existing battery, inverter, and solar system
- Clear advice on compatibility and realistic upgrade options
- Explanation of what can be reused and what cannot
- Upgrade work completed by our
in-house electricians
If upgrading won’t deliver meaningful benefit, we’ll say so and explain why.
Battery upgrade paths we see most often
Every home uses energy a little differently, so we always start with a proper look at your existing system.
From there, common battery upgrade paths can include:
Increasing total storage capacity
Replacing older battery technology with newer systems
Improving blackout backup configuration
Preparing the system for future electrification
What limits battery upgrades?
Battery upgrades are sometimes constrained by:
- Existing inverter compatibility
- Switchboard capacity
- Manufacturer restrictions on mixed systems
- Available space and compliance requirements
We’ll explain these factors clearly so you understand what’s possible, and what isn’t before any decisions are made.
Thinking about a broader upgrade?
Battery upgrades often make the most sense when you are already planning changes to your solar system or inverter. We can look at the whole setup and suggest what’s worth doing together.
