Battery warranty comparison
Compare years, retained capacity, cycle or throughput limits, internet requirements and the exact battery family covered.
COMPARE BATTERY WARRANTIES →Compare solar warranties without reading the fine print first.
A warranty is more than a number of years. Start with the headline cover, then check the one or two conditions that could materially change what that cover means for your home.
Australian manufacturer terms checked 12 October 2026. Exact model and installation date still matter.

Inverter warranty comparison
Compare standard terms, registration requirements, warranty extensions and whether labour, transport or accessories are treated separately.
COMPARE INVERTER WARRANTIES →Why “10 years” does not always mean the same thing
Years + retained capacity
A battery may be covered for ten years but only promise a stated percentage of its original usable energy by the end of that period.
Years + usage limit
Some warranties finish when a cycle or energy-throughput limit is reached, even if the stated number of years has not elapsed.
Standard + extended cover
An inverter may have a shorter standard warranty with extra years available only after registration, monitoring connection or a paid extension.
Hardware is not the whole job
Ask whether the written terms cover labour, freight and site attendance. A free replacement box is not automatically a free replacement job.
Three questions are enough to start
- What exact product and warranty document applies? Model families can have different terms under the same brand.
- What can end or reduce the cover? Look for throughput, cycles, registration, internet connectivity and installation requirements.
- Who pays to make the system work again? Confirm the claim path, labour, freight and the retailer's own obligations.

Use the warranty pages with an actual quote
Once you have model numbers, open the relevant manufacturer profile and current warranty terms together. That is much more useful than assuming one brand is better because its headline number is larger.
