Onboarding by us, data into your app
Customers pair the Zap in the Sourceful app. Once live, telemetry flows through Nova Core into your own consumer app via API. You keep the brand. We own the fiddly bit.
OEM device support out of the box
Sungrow, SolarEdge, Huawei, Deye, Fronius, SMA and more. Modbus, MQTT, OCPP, P1. One gateway for an installer fleet, one API for a utility retail arm.
