Warranty Terms
Subject to the exclusions and limitations in this Limited Warranty, Lunar warrants that:
Energy Capacity: Your system will have an aggregate energy of 10, 15, 20, 25, or 30 kWh (depending on the number of Lunar Battery Blocks) on its initial installation date, and will retain 70% of its energy capacity as measured at the battery AC output at 12.5 years following the initial installation date, subject to the total energy throughput limits below:
System Aggregate Energy | Total Energy Throughput Limit |
10 kWh | 38 MWh |
15 kWh | 56 MWh |
20 kWh | 75 MWh |
25 kWh | 94 MWh |
30 kWh | 113 MWh |
Hardware Defects (12.5 years): Your Lunar Battery Block, Inverter, Hardware Kit, Bridge, Rogowski Coils, and MSA Controller will each be free from defects in material and workmanship for 12.5 years following the initial installation date.
Hardware Defects (25 years): Your Lunar Maximizer and Maximizer Hub will each be free from defects in material and workmanship for 25 years following the initial installation date.
1. Remedies
If your Covered Product does not comply with the limited warranties above, Lunar will, in its sole discretion: repair your Covered Product (using new or refurbished parts), replace your Covered Product with an equivalent product (new or refurbished), or refund you the pro-rated original market price of the Covered Product less reasonable depreciation based on the time of the warranty claim. If your Covered Product is repaired or replaced, the remainder of the original warranty period will apply once the repaired or replacement product is delivered to you.
2. General Exclusions
This Limited Warranty does not apply to any defect or energy capacity shortfall resulting from: (i) abuse, misuse, or negligence; (ii) force majeure events, including lightning, flood, earthquake, fire, or other events outside Lunar's reasonable control; (iii) storage, installation, commissioning, modification, repair, removal and reinstallation, or opening of the external casing performed by anyone other than Lunar, Lunar Energy Services, LLC, or a Lunar certified installer; (iv) failure to operate or maintain your Covered Product in accordance with the Owner's Manual; (v) failure to install in accordance with the Lunar Installation Manual; (vi) any attempt to modify your Covered Product; or (vii) removal and reinstallation at an address other than the original installation location.
This Limited Warranty also does not cover: (a) normal wear and tear, superficial defects, dents, or marks that do not impact performance; (b) noise or vibration that is not excessive or uncharacteristic and does not impact performance; (c) damage or deterioration after the expiration or voiding of the warranty period; or (d) theft of your Covered Product or any of its components. Any costs related to the removal, installation, or troubleshooting of your electrical systems are not covered under this Limited Warranty.
3. Internet Connectivity Requirement
To provide this Limited Warranty for the full warranty period, Lunar needs to update your Covered Products through remote firmware upgrades. If the Covered Products are not connected to the Internet for a consecutive 30-day period (except during a home ownership transfer or interruptions outside your reasonable control), Lunar may not be able to honor your full warranty. In such cases, Lunar will provide a Limited Warranty for at least 5 years following the initial installation date. To avoid this, please download the Lunar App and create a login so Lunar can attempt to contact you if your internet connection is interrupted for an extended period.
4. Who Can Make a Claim
Limited Warranty claims can be made by or on behalf of the Covered Product owner who first acquired and put the Covered Product into use. A subsequent owner who provides (i) basic information about the previous owner, (ii) the site address, and (iii) proof of home ownership is also entitled to make claims.
5. Claims Process
To make a claim, contact the installer who sold you your Covered Product. Please be ready to provide: (i) proof of the original purchase and any subsequent transfers of ownership; (ii) a description of the alleged defect(s); and (iii) your Covered Product's serial number and original installation date.
After January 1, 2025, if Lunar or its affiliates visit the site to assess your claim, a fee may be charged for the visit. This fee will be reimbursed if the Covered Product is found to not comply with this Limited Warranty.
6. Limitations and Disclaimer
THIS EXPRESS LIMITED WARRANTY IS THE ONLY WARRANTY MADE BY LUNAR IN CONNECTION WITH YOUR COVERED PRODUCT. ANY OTHER WARRANTIES, REMEDIES, AND CONDITIONS, WHETHER ORAL, WRITTEN, STATUTORY, EXPRESS, OR IMPLIED — INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND TITLE — ARE EXPRESSLY DISCLAIMED TO THE FULLEST EXTENT PERMISSIBLE UNDER APPLICABLE LAW.
7. Relationship with Applicable Law
This Limited Warranty gives you specific legal rights, and you may also have other legal rights that vary from state to state. Some states do not allow limitations on how long an implied warranty lasts, so the limitations above may not apply to you. The terms of this Limited Warranty apply to the extent permitted by applicable law.
8. Modifications and Waivers
No person or entity, including a Lunar employee or authorized representative, can modify or waive any part of this Limited Warranty. Lunar may occasionally offer to pay some or all of the cost of certain repairs not covered by this Limited Warranty, either for specific Covered Product models or on a case-by-case basis, without incurring any obligation to make similar payments to other Covered Product owners.
9. Limitation of Liability
LUNAR SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO THIS LIMITED WARRANTY, REGARDLESS OF THE FORM OF ACTION OR WHETHER LUNAR HAS BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. LUNAR'S LIABILITY ARISING OUT OF A CLAIM UNDER THIS LIMITED WARRANTY SHALL NOT EXCEED THE AMOUNT YOU PAID FOR YOUR COVERED PRODUCT.
Some states do not allow or restrict the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you, or may only apply to a limited extent.
10. Limitation on Use
YOUR COVERED PRODUCT IS NOT INTENDED FOR USE 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 TO PERSONS, LOSS OF LIFE, OR CATASTROPHIC PROPERTY DAMAGE. LUNAR DISCLAIMS ANY AND ALL LIABILITY ARISING OUT OF ANY SUCH USE.
11. Governing Law
This Limited Warranty shall be governed by the laws of the state where your Covered Product is installed, except to the extent inconsistent with or pre-empted by federal law. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded.
12. Agreement to Arbitrate
If you have a concern or dispute, please send a written notice describing it and your desired resolution to [email protected]. If not resolved within 60 days, you agree that any dispute arising out of or relating to any aspect of the relationship between you and Lunar will be decided by a single arbitrator administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules — not by a judge or jury. Lunar will pay all AAA fees; arbitration will be held in the city or county of your residence. Learn more at www.adr.org.
The arbitrator may only resolve disputes between you and Lunar individually — not class or representative claims. You may opt out of arbitration within 30 days after signing this Agreement by sending a letter to: Lunar Energy, Inc., Attn: Legal Department, 755 Ravendale Drive, Mountain View, CA 94043, stating your name, product, and intent to opt out. You may also take an individual dispute to small claims court.
