Per organizers (Luma)

Engineers, developers, and hardware builders work with real renewable equipment — solar inverters, EV chargers, battery storage, energy meters — on integrations communities need now, with open hardware/software and AI-assisted design workflows. Teams form on the day; challenge details live on the community Zulip channel linked from Luma.

Challenge themes

Programmable Microgrid — plug, play, and own your power
Revive stranded EV chargers — open source + SunSpec standards
Flexible interconnection modeling — microgrid design for constrained grids using EASI
Cooperative cloud — remote microgrid management at scale
Flux AI dev kit — from prototype to production hardware (meshEMS / mInverter PCB workflows)
Bring your own open energy challenge

ISV Tech Comm may run a village metering / northbound MQTT thread inside these challenges — see Meter Interoperability — but the published themes span domestic DER, EVSE, mesh EMS, and grid interconnection, not only energy access.

MeshEMS v2.0 hardware

2026 builds use the NESL 865B board — successor to the 2025 EMS Dev Kit v1. Details, BOM, and firmware: MeshEMS board hub. (ISV’s Power Africa workshop in Nairobi is a separate Sep 2026 program.)
