Opportunity
Supporting Local Innovation in Solar Energy
As part of their “local for local” strategy, the client needed a U.S.-based development partner who could work side-by-side with their new Indiana team.
SEP stood out based on proven experience, and the relationship moved quickly from conversations to an active mulit-year engagement designed to deliver certification-ready software.

Solution
Embedded Innovation for U.S. Solar Markets
Bringing solar technology into the U.S. market required more than code updates—it demanded strong collaboration between SEP engineers and the client’s team. Together, they balanced technical milestones with strategic alignment to speed certification and market readiness.
Embedded Software Development
SEP engineers adapted the inverter software to meet U.S. electrical and communication standards. Using C++ and Yocto, they enhanced the product’s internal API to support American grid configurations, a step required for regulatory approval.
Beyond the code, SEP helped shape the product by leading requirements gathering workshops. Engineers participated in focus weeks (3 continuous weeks) together with both US and global teams to set the stage and gather alignment between global and local teams.
