Franklin WH Solar Battery in Toowoomba
Smart Home Energy Storage Installed by Excel Power
Slash your power bills. Stay protected during blackouts. Keep more of your solar energy powering your home — not the grid.
Excel Power is Toowoomba and the Darling Downs’ trusted local specialist for Franklin WH battery installations. Fully accredited, fully insured, and backed by decades of regional solar expertise — we deliver reliable home energy systems built for Queensland conditions.

Why Toowoomba & Darling Downs Homeowners Choose Franklin WH
Electricity prices in Queensland continue to rise, and feed-in tariffs have dropped significantly — meaning homeowners earn very little when exporting excess solar back to the grid. At the same time, hot summers and growing air-conditioning demand push energy costs even higher across the Darling Downs.
With a Franklin WH battery, you can:
- Store more of your own solar energy instead of sending it to the grid
- Avoid costly peak electricity rates
- Power your home with stored solar in the evening and overnight
- Prepare for EV charging, electrification, and future energy independence


Federal Battery Rebate Eligible
The Federal Government’s solar battery rebate is helping more Queensland households take control of their energy bills sooner. By choosing a compliant system like the Franklin WH, you may be able to access financial support to reduce the upfront cost of home battery storage.
What this means for Toowoomba & Darling Downs homeowners:
- A more affordable pathway to battery ownership
- Faster payback and greater long-term bill savings
- Support designed to reward the use of clean, stored solar energy
- A streamlined rebate process — Excel Power guides you every step of the way

FAQs
Does the Franklin WH qualify for the Federal Battery Rebate?
Yes — the Franklin WH meets the eligibility requirements for the Australian Government’s home battery rebate program. Excel Power will help confirm your eligibility and assist with the rebate application to reduce your upfront cost.
Will Franklin WH work with my current solar system?
In most cases, yes. The Franklin WH is designed to work with both new and existing solar systems. Our team will review your inverter setup and grid connection to ensure seamless integration.
Can Franklin WH power my whole home during a blackout?
It depends on your home’s power supply and which circuits you choose to back up.
Single phase homes can keep key essentials running, while three phase homes may allow for more comprehensive backup or even whole-home protection. Excel Power will design the right backup configuration for your needs.
How long can the battery supply backup power?
Backup duration depends on what you’re powering and how much energy is stored at the time of the outage. For typical Toowoomba homes powering essential loads, many customers see several hours — often long enough to ride through short outages.
Can I expand my storage later?
Yes. Franklin WH is modular and allows you to add more batteries as your energy needs grow — whether you buy an EV, expand your home, or simply want greater independence from the grid.
How long does installation take?
Most Franklin WH installations are completed in one day, depending on site conditions and system size. Excel Power handles everything — installation, setup, and safety checks — so you can start storing solar right away.
Can Franklin WH participate in a Virtual Power Plant (VPP)?
Yes. The Franklin WH is VPP-ready, meaning you can earn rewards by supporting the energy grid when demand is high — once connected to an eligible program. Excel Power will let you know when VPP options are available in the Toowoomba region.
