Feed-in tariffs are lower
A battery helps you keep more of the solar you already generate instead of sending it back cheaply.
Battery, if it actually makes sense.
Already have solar? Rayamp assesses the current system, your evening usage, likely rebates and GloBird fit before recommending storage.
Existing solar Battery-only pathway for homes that already generate.
VIC only Focused on Melbourne and regional Victoria households.
Assessment first No hard sell if the savings profile is weak.
Why battery now
Why more VIC homeowners are adding storage.
The economics have shifted. Lower feed-in tariffs, higher evening rates and softer battery pricing together make storage worth a fresh look for Victorian homes with solar.
Evening bills still matter
For many VIC homes, the expensive part of the day starts after solar generation drops away.
Battery prices have softened
Storage is more accessible than it was a few years ago, and the payback now stacks up for a lot more households than it used to.
Who battery is for
Rayamp checks the home before it recommends the hardware.
A battery only makes sense when the system, the home and the tariff line up. Rayamp walks through each of these before recommending hardware, so the answer is grounded in how you actually use power.
Existing solar system
Battery-only is for households that already have panels and want to use more of that generation at home.
High evening usage
Cooking, heating, cooling and late-night appliance use are strong signals that storage may help.
Tariff and rebate fit
Rayamp checks Solar Victoria rebate eligibility and GloBird-compatible charging windows before recommending a battery.
Honest savings check
If the payback is weak or the fit is wrong, the recommendation is not yet. No hard sell, no pressure.

FAQ
Common battery questions.
Can I add a battery to my existing solar?
Yes. This page is specifically for homes that already have solar and want to add storage after a compatibility check.
Will a battery work during a blackout?
Many battery setups can support essential backup circuits. Rayamp can confirm the right configuration during assessment.
What size battery do I need?
It depends on your solar output, evening usage and goals. Bill size is a useful starting point, but Rayamp sizes each battery against how your household actually runs, so you are not paying for capacity you will never use.
How long does installation take?
Battery installs are usually completed in about 1-2 days, depending on the existing setup and any switchboard work required.
What warranty comes with the battery?
All Rayamp battery packages include a 10-year manufacturer product warranty on the battery, covered by SolaX or Sigenergy, plus workmanship cover on the installation itself.
What rebates and loans can I access?
Eligible Victorian households can apply the Solar Victoria home battery rebate and interest-free loan. Rayamp confirms eligibility during the assessment and handles the paperwork as part of the install.
