Why distributed energy resources testing matters

EV chargers, heat pumps, home batteries and solar systems are becoming part of the grid. To earn that place, they must respond correctly to grid signals, work with other manufacturers’ platforms and stay secure. One faulty response, repeated across thousands of homes, becomes a grid problem. Resillion tests DER products against standards such as OpenADR, OCPP and G99, and checks how whole systems behave together, in our own labs and in PNDC’s real-grid test environment at the University of Strathclyde. You get the evidence you need for certification, grid approval and launch.

The aim: Energy products that connect safely, work together and help keep the grid in balance.

CASE STUDY

Delivering the UK’s first vehicle-to-grid bundle certification with Octopus Energy

Octopus Energy’s Power Pack bundle pairs a BYD Dolphin EV with a Zaptec Pro bidirectional charger and the Kraken platform, so customers can export power back to the grid. To do that, the whole system had to pass the UK’s G99 grid-connection standard, with no existing test pathway for AC vehicle-to-grid. Resillion led the compliance and evidence plan, ran shakedown testing and all 14 mandatory G99 tests at PNDC, and carried out a full cyber security assessment across the bundle.

The result?

Octopus secured full G99 certification and ENA Type Test Register support, creating a first-of-its-kind certified V2G customer offering ready for commercial rollout.
