Terms and Conditions

Shipping Policy

Teragy Solar provides shipping services to customers within the United States and Canada. The Customer must use a specific street address for shipping. The USPS does not allow batteries to ship to Post Office boxes.


Teragy Solar cannot ship items by air, as delivering lithium phosphate batteries by air is too dangerous. Orders needing freight can be shipped by boat as necessary. All shipping charges involving freight are estimates to the best of our abilities. If needed, a Teragy Solar representative will call you to collect the remaining balance in the event freight charges surpass the estimated cost. The specifics will vary by order.


Teragy Solar reserves the right to decline any order by freight. Orders that are too large or small may not be eligible for freight service. The Customer will receive full details on whether Teragy Solar can ship the product and what transportation measures will work.

Shipping Cost

Occasionally, Teragy Solar offers free shipping on all products to customers in the continental United States and Canada. On orders outside of our free shipping specials, freight charges are commonly estimated upon checkout. In the event your freight shipping surpasses your estimated shipping cost, a Teragy Solar representative will call you to collect the remaining shipping balance. 

While free shipping is available to customers in Canada, it will cost extra to order an item that is out of stock in Canada but is available in the United States. Shipping and customs fees may apply, plus duty and GST may be imposed based on the value of the order. Additional shipping charges may apply for orders going to Alaska or Hawaii. Import taxes will vary by country. Customers should consult with their local judiciary office for help finding specific tax rules in the area.

Delivery Measures and Times

Most orders are processed using UPS Ground for domestic shipping. Customers will receive a tracking number when the order ships. It takes about five to eight days for orders to ship after order placement. An additional one to three days will be necessary for packing and shipping the battery from the warehouse.

For orders or shipments to Alaska and Hawaii, Teragy Solar will use FedEx, DHL, or USPS. The option depends on the product the Customer orders and where it will go. Teragy Solar will provide further details on additional charges for shipments to Alaska, Hawaii, or other countries as necessary. Expedited or overnight shipping is not available for any purchases due to federal shipping rules surrounding the transport of batteries.

Order Status

Payment Methods

Teragy Solar accepts all major credit card payments, including payments from Visa, MasterCard, Discover, and American Express.
