Growatt Batteries vs Fox ESS Batteries: Which Solar Battery Is Right for Melbourne Homes?

 As electricity prices rise and battery rebates evolve, Melbourne homeowners are increasingly turning to solar batteries to maximise self-consumption, gain backup power, and future-proof their energy needs. Two of the most popular and trusted battery brands in Australia today are Growatt and Fox ESS.

At Climate Green Melbourne, we install and support both Growatt and Fox ESS battery systems across metropolitan Melbourne and regional Victoria. This guide compares the two brands side by side to help you choose the right solution for your home or business.

Why Install a Solar Battery in Melbourne?

Installing a solar battery allows you to:

  • Store excess solar energy instead of exporting it at low feed-in tariffs

  • Use stored power at night and during peak pricing periods

  • Reduce reliance on the grid

  • Prepare for future Virtual Power Plant (VPP) programs

  • Protect your home from blackouts (with backup-enabled systems)

With federal STCs, Solar Victoria incentives, and upcoming changes from 1 May 2026, choosing the right battery size and brand has never been more important.

FAQs – Growatt vs Fox ESS Solar Batteries

Are Growatt and Fox ESS batteries eligible for rebates in Victoria?

Yes. Both Growatt and Fox ESS batteries are CEC-approved and eligible for STCs and applicable Solar Victoria battery incentives, subject to eligibility criteria.

Which battery is better for a large home?

Fox ESS is generally better for larger homes due to its high-voltage design and greater scalability, especially if your energy usage exceeds 20–30 kWh per day.

Can I add more battery capacity later?

Yes. Both brands offer modular systems, but Fox ESS allows larger expansions and multi-stack configurations, making it more future-proof.

Are these batteries safe?

Absolutely. Both Growatt and Fox ESS use Lithium Iron Phosphate (LiFePO₄) chemistry, which is widely regarded as the safest lithium battery technology.

Do solar batteries work during blackouts?

Only if your system is configured with backup capability. Climate Green can design your system to support essential circuits during outages.

Will battery rebates reduce after 2026?

Yes. From 1 May 2026, battery rebates will taper as system size increases, making early installation more financially attractive—especially for larger batteries.
