Who We Are

Day Ahead systems protect the grid and the PV systems which connect to it.

DAI use only the highest quality, utility grade components and are designed and built to meet or exceed industry standards.

DAI relays are designed to meet the specific requirements of your utility company for the location where they are installed.

DAI relays protect the PV owner’s equipment from high fault currents on their side of the PCC.
DAI RTUs provide industrial grade, accurate, real time monitoring of the PV system’s performance. DAI communication devices are reliable, durable, and designed to work seamless with your utility.

Principles of Our Work

Design-build the best quality protection for the grid and your PV system:

1. Verify your company’s and your utility’s requirements for each installation.

2. Create turn-key systems that are simple and fast to install.
3. Deliver those systems faster than any other company.
