Battery and inverter warranties are set by the manufacturer, and they vary by brand and model. Installer workmanship is usually covered separately.
When comparing warranties, look at:
- how long the battery and inverter are covered
- what counts as a fault, and what doesn’t
- whether the installer’s own workmanship guarantee is included
Ask for the exact terms in writing for the system you are considering. Every Solar Heaven installation comes with a standard 5-year workmanship warranty, and we confirm the manufacturer warranty for each brand we fit in your quote.
