Warranty reference
Inverters warranty terms
Every inverter brand in the catalogue, compared on the terms that decide a claim: parts, labour, and what has to stay true.
Checked 16 August 2026
Inverter warranties in this catalogue run from 10 to 12 years on parts. Almost none of them have a registration deadline, and almost none pay for labour. What several of them do have is a condition: GoodWe holds its 10 year term only while the inverter is connected to the SEMS portal, otherwise it is five, and nothing tells you when the connection drops.

Every brand, side by side
Parts terms run from 10 years to 12. Labour is where they separate: most pay nothing, and the exceptions are worth knowing before you quote a service call.

The ones with something to confirm
These brands hang the full term on something staying true. No clock, no notification, and the consequence only shows up at the claim.
SolarEdge
Inverter
SolarEdge's standard 12 year inverter term needs no registration and starts at the earlier of installation or four months from shipment. The only clock is the paid extension: if the customer wants 20 or 25 years, it has to be bought within 24 months of shipment.
Enphase
Inverter · Battery
Enphase IQ8 microinverters carry 25 years, applied from Enlighten activation, so the thing to confirm is that activation happened. In the United States Enphase also pays labour: $200 per truck roll plus $25 per replaced microinverter, and a paid Labor Protection Program extension stretches labour cover to five or ten years from activation..
SMA
Inverter
SMA's US residential inverters carry a 10 year factory warranty. Registering in SMA's Online Service Center is how the warranty record attaches to the unit, and it is the door to paid extensions later, which can be bought any time during the factory term up to 20 years total.
EG4
Inverter · Battery
EG4's current inverters and batteries carry 10 year terms. EG4 asks for registration within the first year of purchase, with proof of purchase from an authorised distributor accepted as the fallback.
GoodWe
Inverter
GoodWe has no registration deadline, but its 10 year term is conditional. The inverter has to be connected to the SEMS portal and uploading generation data, and a hybrid running a Lynx battery needs both serials registered.
Sol-Ark
Inverter
Sol-Ark's 10 year limited warranty runs from initial purchase or receipt by the end user, whichever is later, so the purchase paperwork belongs with the job. Registration guidelines exist, and owner installs carry extra hold harmless conditions, which makes recording who installed the unit part of the warranty record..
