TL;DR: Most GoodWe inverters carry 5 or 10 years depending on the series, EV chargers get 2 years, and the extended 10-year cover has conditions you have to actively meet. Register the system and connect it to SEMS or you will not get it.
What is the Standard GoodWe Inverter Warranty in 2026?
GoodWe's limited warranty covers the inverter and the accessories that make it work. How long you get depends entirely on the series: the volume models get 5 years, the premium and higher-capacity units get 10 out of the box.
GoodWe Inverter Warranty Periods
Five years covers most on-grid inverters, the NS, XS G3, DNS G4, MS and HT series, and the ES, EH and EM hybrids.
Ten years covers the premium on-grid GT series and the larger hybrids, the ET 15K-30K and ET G2 series.
Accessories differ again. The STS series gets 5 years. WiFi modules, meters and monitoring devices get 2.
One worth knowing: DNS, DNS G3, MS and MS G3 owners get an extra 5 years (60 months) of spare parts warranty, covering the hardware cost of a replacement inverter once the initial 5 years runs out.
Starting Your Inverter Warranty Period
The clock starts on whichever comes first: the day it was installed, or 12 months after the manufacturing date. So an inverter that sat in a warehouse for a year is already burning warranty before it reaches your roof. Ask for the manufacturing date, not just the install date.
If you run a GoodWe hybrid off-grid, keep the battery's State of Charge above the protection value in the manual. Dropping below it repeatedly damages the battery and gives GoodWe grounds to decline a claim.
How Can You Get a 10-Year GoodWe Inverter Warranty?
GoodWe runs promotions that extend many inverters to 10 years. None of them are automatic. You have to register, connect to the Smart Energy Management System (SEMS) portal, and in some cases pair with a GoodWe battery.
General On-Grid and Hybrid Ready Promotion
Many on-grid models and the EH hybrid ready (EHR) series qualify if the inverter was installed, registered and connected to SEMS after 1 January 2021, and manufactured after 1 July 2020.
The extension starts when the standard 5-year warranty ends. It does not stack on top of a separately purchased extended warranty.
ET and EH Series Hybrid Inverter Promotion
For ET 5-10kW and EH series, the 10 years depends on battery pairing. You need a GoodWe Lynx Home F or Lynx Home F PLUS+ battery, the inverter connected to SEMS and actually uploading generation data, and a production date after 1 January 2021.
Then register both serial numbers, inverter and battery, through the GoodWe portal link. Skip that step and the extension does not exist, whatever your installer told you.
What Warranty Do GoodWe EV Chargers Carry?
Shorter than the inverters. Two years, covering the charger and the parts that come with it.
GoodWe EV Charger Warranty Terms
Two years on the GW7K-HCA, GW11K-HCA and GW22K-HCA, and on supplied accessories including the Residual Current Devices. The period starts on the install date or six months after production, whichever comes first.
Making an EV Charger Warranty Claim
Have this ready: your contact details, the model and serial number, software version, install and failure dates, and how often the fault occurs. GoodWe expects the claim within one month of the failure date, so do not sit on it.
Add installation details including weather conditions, photos or video of the fault, information about your grid supply, and any error codes shown on the charger or in the SEMS Portal. GoodWe may send someone out, and you have to provide safe access.
What Is the General Process for a GoodWe Warranty Claim?
Same path for an inverter, a battery or a charger: local first, GoodWe second.
Initial Steps for Any Warranty Claim
Contact the distributor you bought from or the installer who fitted it. They are GoodWe's default service channel, they know your system, and they can usually diagnose it faster than a ticket will. Have the model, serial number and installation date in front of you.
Escalating a Claim to GoodWe Directly
If the installer cannot resolve it, or will not, raise a service ticket with GoodWe directly. Inverter claims go through the Zendesk portal; EV charger claims through the general support portal. GoodWe audits its service channels, so escalation is a real path rather than a formality.
Key Takeaways
- Inverters carry 5 or 10 years depending on the series; check yours rather than assuming.
- EV chargers carry 2 years, including the supplied RCDs.
- The 10-year extension requires registration, a SEMS connection, and for ET and EH hybrids a paired Lynx Home battery. Miss a step and you do not have it.
- The warranty clock can start 12 months after manufacture, so a long-stored inverter arrives with less cover than you think.
- Go to your installer or distributor first, then escalate to GoodWe if that fails.
