Who it's not for
- No solar: no federal discount [SB-S003, C].
- Renters, unless the owner agrees [SB-S003, C].
Will it pay for itself?
- Yearly saving ≈ kWh the battery covers each evening × 365 × (your peak rate − your feed-in rate) (E).
- Payback years = what you pay after discounts ÷ yearly saving (E).
- Check the warranty: most batteries we cover promise 70% of usable storage at 10 years, or a throughput cap, whichever comes first [SB-S053, SB-S055, SB-S057, SB-S059, C]. If payback is past 10 years, think twice (E).
See a worked example with a real published tariff on our Sigenergy price page (example only, use your own bill).
A seller must give you payback, sizing and warranty details before you sign [SB-S082, C].
Choosing an installer
- Solar Accreditation Australia battery accreditation. Check it [SB-S063, SB-S064, C].
- The exact system name on the CEC approved list, written on your quote [SB-S026, SB-S069, C].
- The install date and certificate count, in writing [SB-S004, C].
