How to Obtain Warranty Service

To obtain warranty service for a Product, the Owner must comply with the Return Merchandise Authorization (RMA) Procedure. Unless HarmoniLiving specifically instructs the Owner otherwise, the Owner must return the allegedly defective Product to Mango Power in the original packaging or equivalent. If the allegedly defective product is not received by Mango Power within 60 days after HarmoniLiving has provided an RMA (Return Merchandise Authorization) number to the owner as part of the RMA Procedure, HarmoniLiving will issue an invoice to the owner. The owner will then be responsible for paying the current list price for a new product or replacement product.

If an Owner returns a Product to HarmoniLiving (1) without an RMA from Mango Power or (2) without all parts included in the original package, HarmoniLiving retains the right to either (i) refuse delivery of such return; or (ii) charge a restocking fee equal to the higher of fifteen (15) percent of the original Owner’s purchase price of the Product or the retail value of the missing parts.

By returning a Product, the Owner hereby acknowledges that ownership of the Product is transferred to Mango Power upon Mango Power’s receipt of the Product. If the claim is justified based on this Limited Warranty, HarmoniLiving will bear the cost of shipping the repaired or replacement Product to the Owner at the Original Location. Any Product returned to HarmoniLiving that HarmoniLiving determines is not covered under this Limited Warranty, or that is returned to Mango Power without a valid RMA, may be rejected and returned at the Owner’s cost (subject to prepayment) or kept for 30 days for pick-up by the Owner, and then disposed of in Mango Power’s sole discretion without further liability or obligation to Owner.

Remedies

During the applicable Warranty Period, if Mango Power confirms the existence of a defect that is covered by the Limited Workmanship Warranty, Mango Power will, at Mango Power’s option, either (1) repair or replace the Product free of charge or (2) refund the Owner the actual purchase price for the Product less reasonable depreciation based on use at the time the Owner notifies Mango Power of the defect. Mango Power will not elect to issue a refund unless (i) Mango Power is unable to provide a replacement and repair is not commercially practicable or cannot be timely made, or (ii) the Owner is willing to accept such a refund. In the event of a defect, to the extent permitted by law, these are the Owner’s sole and exclusive remedies.

During the applicable Warranty Period, if Mango Power establishes the existence of a defect that is covered by the Limited Capacity Retention Warranty, Mango Power will, at Mango Power’s option, either (1) repair or replace the Product free of charge, (2) issue a pro-rated refund for the Product to the Owner in an amount up to its actual value at the time the Owner notifies Mango Power of the defect, or (3) issue store credit for the capacity lost over the Warranty Period, as determined in Mango Power’s sole discretion, towards the Owner’s purchase of a new Mango Power Battery. Mango Power will not elect to issue a refund or a credit unless (i) Mango Power is unable to provide a replacement and repair is not commercially practicable or cannot be timely made, or (ii) the Owner is willing to accept such a refund.

If Mango Power repairs or replaces the Product, (1) Mango Power will, at its option, use new and/or reconditioned parts or products of original or improved design, and (2) the Limited Warranty will continue to apply to the repaired or replacement product for the remainder of the original Limited Warranty Period or ninety (90) days from the date Owner receives the repaired or replacement product, whichever is later, as long as the repaired or replacement product is installed and connected to the internet within 45 consecutive days from the date on which you receive the repaired or replacement product and remains continuously connected to the internet after that (except where such connectivity is interrupted by causes outside of the Owner’s reasonable control).

If Mango Power issues a refund or store credit, as applicable (rather than providing a repaired or replacement Product), such refund or store credit will be processed and paid within two weeks of Mango Power's receipt of the Product.

Limited Warranty Limitations and Exclusions

This Limited Warranty does not include any cost of labor or other costs related to (1) uninstalling the Product; (2) re-installing a repaired or replacement product, or (3) the removal, installation, or troubleshooting of the Owner's electrical systems.

The Limited Warranty does not cover, and Mango Power will not be responsible for, shipping damage or any other damage caused by the mishandling of products by the freight carrier.

In order to provide this Limited Warranty for the entire ten years warranty period, Mango Power requires the ability to update the Product through remote firmware upgrades. Installation of these remote upgrades may interrupt the operation of the Product for a short period.

This Limited Warranty does not apply to, and Mango Power will not be responsible for, any defect in or damage to any products: (1) if the Product is not connected to the internet within 45 consecutive days following the Warranty Start Date and continuously connected to the internet thereafter, unless such lack of connectivity is due to causes outside of the Owner’s reasonable control; (2) that have been misused, neglected, tampered with, altered, or otherwise damaged, either internally or externally; (3) that have been improperly installed, operated, handled or used, including use under conditions for which the product was not designed, use in an unsuitable environment, or use in a manner contrary to the User Manual, Installation Manual, or applicable laws or regulations; (4) that have been subjected to fire, water, generalized corrosion, biological infestations, acts of nature, or input voltage that creates operating conditions beyond the maximum or minimum limits listed in the applicable Product Data Sheet, including high input voltage from generators or lightning strikes; (5) that have been subjected to damage caused by third party components not provided by Mango Power and used with the Products or any damage to the Products caused by service performed by anyone who is not a representative of Mango Power; (6) if the original identification markings (including trademark or serial number) of such products have been defaced, altered, or removed (other than by fading through regular wear and tear); (7) if the Grid Profile (utility approved operating parameters) of the Product has been altered, and such alteration causes the product to malfunction, fail, or fail to optimally perform.

The Limited Warranty does not cover cosmetic, technical, or design defects or shortcomings which do not materially influence or affect energy storage or degrade form, fit, or function of the Products; noise or vibrations that are not excessive or uncharacteristic and do not impact the Product’s Performance; or any defects or parts requiring replacement due to ordinary wear and tear, corrosion, rust or stains, scratches, dents on the casing or paintwork of the Product.

The Limited Warranty does not apply to any third-party products that may be installed with the Products at the Original Location.

To avoid doubt, software programs installed in the Products and the recovery and reinstallation of such software programs and data are not covered under this Limited Warranty. Mango Power does not warrant that the operations of the Product will be uninterrupted or error-free. No Mango Power employee or authorized reseller is authorized to make any modification, extension, or addition to this Limited Warranty. If any term of this Limited Warranty is held to be illegal or unenforceable, the legality or enforceability of the remaining terms shall not be affected or impaired.

Products are not intended as a primary or backup power source for life-support systems, other medical equipment, or any other use where product failure could lead to injury, loss of life, or catastrophic property damage. Mango Power disclaims all liability arising from any such use of your Products. Further, Mango Power reserves the right to refuse to provide support in connection with any such use and disclaims any liability arising out of Mango Power’s provision of, or refusal to provide, support for your Product in such circumstances.
