How to Obtain Warranty Service
1 To obtain warranty service for a Product, the Owner must comply with the Return Merchandise Authorization (RMA) Procedure. Unless Mango Power 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 Mango Power has provided an RMA (Return Merchandise Authorization) number to the owner as part of the RMA Procedure, Mango Power 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.

2 If an Owner returns a Product to Mango Power (1) without an RMA from Mango Power or (2) without all parts included in the original package, Mango Power 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.

3 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, Mango Power will bear the cost of shipping the repaired or replacement Product to the Owner at the Original Location. Any Product returned to Mango Power that Mango Power 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
1 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.

2 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.

3 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).

4 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.
Return Merchandise Authorization Procedure
To obtain repair or replacement services, store credit, or refund (as applicable) under the Limited Warranty, the customer must comply with the following policy and procedure:

• Owners may contact the installer of record to evaluate and troubleshoot the problem while the Mango Power product is in the field. If the Owner has no installer associated with your Products, Owners may contact Mango Power at https://www.mangopower.com/pages/contact-us to find a service firm in your area.

• Alternatively, the installer can contact a Mango Power Customer Service representative to evaluate and troubleshoot the problem while the Mango Power product is in the field as many issues can be solved. Mango Power Customer Support can be reached at https://www.mangopower.com/pages/contact-us.

• If in-field troubleshooting does not solve the problem, the Owner may return the defective product to Mango Power with a Return Merchandise Authorization (RMA) number, which the Owner must request from Mango Power. The RMA request must include the following information:
1. Proof-of-purchase of the defective product in the form of (1) the dated purchase receipt from the original purchase of the product at the point of sale to the end-user or (2) the dated dealer invoice or purchase receipt showing the original equipment manufacturer (OEM) status, or (3) the dated invoice or purchase receipt showing the product exchanged under warranty;
2. Model of the defective product;
3. SN number of the defective product;
4. Detailed description of the defect;
5. Shipping address for return of the repaired or replacement product (as applicable).
• Upon issuance of the RMA, Mango Power will ship the replacement unit to the address where the Mango Power Product is installed. In certain circumstances, Mango Power may require the defective Product to be returned before shipment of replacement products.

•When the replacement unit arrives, Owner must return the defective product in the original shipping box or other packaging that is equally protective of the product. Mango Power will email the Owner requesting information for shipping vendor pick-up, and Mango Power will email the Owner a shipping label. After that, Owner should call the shipping vendor to apply for pick-up service.

•If the defective product or part is not received by Mango Power within 60 days of issuance of the RMA, Mango Power will invoice the Owner, and the Owner will pay the then-current list price for such new product or part.

• If in-field troubleshooting of the Mango Power product is not able to be accomplished, and the unit is determined upon receipt and testing by Mango Power personnel as being fully operational (no trouble found), the Owner will incur a $200 handling fee.

•The returned defective product must not have been disassembled or modified without the prior written authorization of Mango Power.
Limited Warranty Limitations and Exclusions.

2. 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.

3. 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. By installing the Product and connecting it to the internet, the Owner consent to Mango Power updating the Product through these remote upgrades from time to time without further notice to the Owner. If the Product is not connected to the internet for more than 45 consecutive days or has yet to be registered with Mango Power, important remote firmware upgrades may not be possible.

4. 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.

5. 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.

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

7. 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.

8. 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.
