Refund policy

Prior to any return, customers must contact us with their original sales order number and obtain a Return Material Authorization (RMA) number.

The assigned RMA number is valid for 60 days from the date issued and the return must be received in that time frame. The customer is responsible for return shipping charges and encouraged to use only reputable carriers capable of providing proof of delivery and insurance for the value of the shipment. Zero Bills  Solar Generators will only provide a prepaid waybill or reimburse the return shipping costs if the return is a result of our error.


Unless otherwise stated, to be eligible for a refund, merchandise must be returned in the original packaging within 60 days from original delivery. The return must be in new and resalable condition with original manuals and all accessories included. If any component of the returned product is missing, Zero Bills  Solar Generators may reject the return or choose to impose additional charges.

From receipt of return, a minimum of three business days is required to inspect the returned item prior to issuing a refund or credit. Shipping charges are non-refundable.


Unless otherwise stated, to be eligible for an exchange or credit, merchandise must be returned in the original packaging with original manuals and all accessories included.

• Wrong Orders: If you receive a different item from what you ordered, Zero Bills  Solar Generators will ship the correct item and provide a prepaid return label to return the incorrect item. 
• Dead On Arrival (DOA): Items that fail within 10 days of receipt and the failure is not a result of customer negligence, Zero Bills  Solar Generators will provide a replacement item, either in advance or once the defective item is returned; a prepaid return label will be provided.

Damage That Occurs During Shipping:

  1. Must be reported to Zero Bills  Solar Generators immediately upon arrival. Damage that occurs after you receive the order is the sole responsibility of the customer.
  2. You must take picture of the the damaged items and the shipping box and any inner shipping material that is inside (such as foam inserts and air cushions, etc.)
  3. We will provide a replacement of the specific item that is damaged. For example, if the charge controller is broken, we will send a replacement charge controller, etc.
  4. Warranty does not apply to systems that are shipped for use overseas after the original purchase. We are not responsible for damage or defects caused by a third party shipper.
