The Open Smart Meter solves a problem that affects most solar developers in the industry. This inexpensive and open source Smart Meter meets IEC and key elements of the local regulations in Nigeria.
In order to offer Energy as a Service, where the solar solution provider maintains ownership of the solar equipment and charges customers per for exactly what they consume, it was important for First Electric to have an inexpensive and OEM agnostic GSM prepaid smart energy meter that could be deployed one unit at a time.
Particularly in urban areas that already have a level of grid connectivity, being able to deploy solar solutions to an individual customer or a cluster of customers without having to worry about minimum viable order quantity brings much needed flexibility that will certainly help other Energy Providers, both in Nigeria and around the world.
This document summarizes the manufacturing guide to enable a skilled person (with software engineering knowledge) to manufacture the smart energy meter.
