FAQs

Why does Enphase Energy offer a 100% Uptime Guarantee?
Enphase Energy is committed to designing and manufacturing the most reliable inverter system in the industry. We believe that if our product malfunctions, you should not have to pay for lost power. We stand behind this promise by reimbursing you for the value of any lost power.
Does this mean I should expect my micro-inverters to fail?
No. Enphase Micro-inverters have a Mean Time Between Failure (MTBF) rating of 119 years. It is because of our confidence in this low failure rate that we are offering this guarantee.
How do I know if I am eligible for the 100% Uptime Guarantee?
All registered customers with a valid Enlighten website account are eligible.
Why do I need to have a current Enlighten subscription?
This is our way of ensuring that the Enphase Micro-inverter was purchased and installed properly and that the power outage was due to an Enphase inverter failure.
How is the reimbursement calculated?
The reimbursement is calculated as the estimated energy production loss in kWh multiplied by the reimbursement rate of $0.20 per kWh. The energy production loss is estimated by viewing the production of a neighboring module for the total of the outage period. There is a limit of 30 days for the reimbursement period calculation.
Can I apply for reimbursement through my installer or distributor?
No. Please contact Enphase Energy directly to initiate the reimbursement process. Complete the 100% Uptime Guarantee Reimbursement Form and return to Enphase Energy, or call 877.797.4743 between the hours of 8:00 A.M. and 5:00 P.M.
