Envoy Installation and Operation

Appendix A — Limited Warranty

Enphase Energy Inc. ("Enphase") has developed a highly reliable Envoy Communications Gateway that is

designed to withstand normal operating conditions when used for its originally intended purpose in

compliance with the Enphase User Manual supplied with the originally shipped system. The Enphase limited

warranty ("

Limited Warranty") covers defects in workmanship and materials of the Envoy Communications

Gateway ("

Defective Product") for a period of one (1) year from the date of original purchase of such Envoy

Communications Gateway at point of sale to the originally-installed end user location (the "

Warranty Period").

During the Warranty Period, the warranty is transferable to a different owner as long as the Envoy

Communications Gateway remains installed at the originally-installed end user location.

During the Warranty Period, Enphase will, at its option, repair or replace the Defective Product free of charge,

provided that Enphase through inspection establishes the existence of a defect that is covered by the

Limited Warranty. Enphase will, at its option, use new and/or reconditioned parts in repairing or replacing the

Defective Product. Enphase reserves the right to use parts or products of original or improved design in the

repair or replacement of Defective Product. If Enphase repairs or replaces a Defective Product, the Limited

Warranty continues on the repaired or replacement product for the remainder of the original Warranty Period

or ninety (90) days from the date of Enphase’s return shipment of the repaired or replacement product,

whichever is later.

The Limited Warranty covers both parts and labor necessary to repair the Defective Product, but does not

include labor costs related to un-installing the Defective Product or re-installing the repaired or replacement

product. The Limited Warranty also covers the costs of shipping repaired or replacement product from

Enphase, via a non-expedited freight carrier selected by Enphase, to locations within the United States

(including Alaska and Hawaii) and Canada, but not to other locations outside the United States or Canada.

The Limited Warranty does not cover, and Enphase will not be responsible for, shipping damage or damage

caused by mishandling by the freight carrier and any such damage is the responsibility of the freight carrier.

To obtain repair or replacement service under this Limited Warranty, the customer must comply with the

following policy and procedure:

• All Defective Product must be returned with a Return Merchandise Authorization Number (RMA)

which customer must request from Enphase. Before requesting the RMA, however, the customer

should contact an Enphase technical support representative to evaluate and troubleshoot the

problem while the Envoy Communications Gateway is in the field, since many problems can be

solved in the field.

• If in-field troubleshooting does not solve the problem, Customer may request the RMA number,

which request must include the following information:

• Proof-of-purchase of the Defective Product in the form of (1) the dated purchase receipt

from the original purchase of the product at point of sale to the end user, or (2) the dated

dealer invoice or purchase receipt showing original equipment manufacturer (OEM) status,

or (3) the dated invoice or purchase receipt showing the product exchanged under warranty

• Model number of the Defective Product.

• Serial number of the Defective Product.

• Detailed description of the defect.

• All Defective Product authorized for return must be returned in the original shipping container or

other packaging that is equally protective of the product.
