Schedule a free 20-minute design consultation with an HOUSEI Expert to review system options. Afterward, you’ll receive a proposal with at least two options to review. Once you review the contract and pay the refundable deposit, our installer will schedule a remote or on-site visit to confirm your final price and timeline. After the installer gets permits and installs the system, the HOUSEI team will host a Walkthrough Call with you to explain the battery’s settings, complete the program enrollment, and ensure that you’re comfortable with your new battery’s operation. The entire process takes approximately 3 months from the date of the deposit to the Walkthrough Call.
