Powering California’s Clean Energy Goals with Scalable, Smart Grid Solutions

We supported a U.S.-based provider of solar-powered energy solutions as they prepared to enter the California market, a state with some of the most advanced renewable energy standards in the world.
To participate in California’s programs, the client’s devices had to comply with the IEEE 2030.5 protocol. The challenge was to enable secure, real-time communication between thousands of solar inverters and the grid aggregator without sacrificing performance or cost-efficiency.

Our engineering team delivered:

• Refactored embedded software to ensure protocol compliance and scalability
• A custom middleware mapper for IEEE 2030.5 communication
• A working Proof of Concept on real inverter hardware
• A cloud-native, event-driven architecture on AWS
• TLS 1.3 for secure transmission and MQTT for lightweight messaging
• A modernized installer app UI with simplified workflows
• Infrastructure monitoring and cost optimization features

The result:
The PoC is now undergoing compliance validation. With this future-proof, scalable solution, the client is ready to launch in California, and we’re proud to be part of their journey.
