We offer Deye inverters and batteries from the EU that come with a full official 10-year manufacturer’s warranty. Our competitors mostly import the same Deye inverters from China, but with a limited 5-year warranty.
In this article, we’ll explain why it’s important to choose an inverter with an official 10-year warranty rather than a cheaper option from China.
The risk of inverter failure is highest after year 5
Statistics show:
- in the first 5 years, only ~0.9% of inverters fail;
- over 15 years — more than 34%;
- the peak of failures falls between years 6 and 10.
When the 5-year warranty has already expired, the risk of failure increases many times over. More than one in three inverters fails after the standard 5-year warranty ends.
Plus, in the event of a failure, the system sits idle while diagnostics, replacement, or the purchase of a new inverter takes place. That’s why a 10-year warranty is critically important: it covers the period when the risk of failure is highest.
European legislation and warranty
European legislation requires manufacturers to provide a warranty of at least 10 years for inverters. Therefore, all Deye inverters imported through official European channels have a 10-year warranty period. Inverters brought in from China, even if they are the same Deye brand, have only a limited 5-year warranty. This means that after 5 years the customer has no protection in the event of a failure.
What happens without a warranty
- A failure after 5 years = buying a new inverter at your own expense.
- This is not only direct expenses but also a loss of power generation during downtime.
- On average, the inverter accounts for up to 20–30% of the total cost of the PV system, so a repeat purchase significantly reduces payback.
EU inverters are serviced by a faster local service
Deye inverters supplied through official European channels are serviced at the service center in Lviv.
This allows for fast diagnostics, replacement, or repair without waiting for parts from China or lengthy logistical delays. The service is local, transparent, and controlled.
During warranty repairs, we provide a temporary inverter so your system continues to operate without downtime and energy losses.
