Supplier warranty conditions

• Manufacturer's warranty: 10 years (120 months) from purchase.
• Activation requires the inverter serial number, purchase invoice and a certified electrician's confirmation of input-side lightning and overvoltage protection, lightning protection between the panels and inverter, a DC isolator between the panels and inverter, and dedicated panel grounding separated from the building grounding.
• Lightning damage is treated as an insurance claim and is not covered by this warranty.
