Built where the tariff bites.
Enertia is a South African energy management system, designed for the grid, the tariffs and the load-shedding our sites actually live with.
A controller that would not take the brand’s word for it.
Enertia grew out of hands-on work with solar and battery installations, and out of a peak-shave controller that ran on a real commercial site.
That controller taught us two things. The first is that real equipment does not always behave the way its interface suggests: a limit you set is not always a limit that is enforced, and some systems have only one lever that truly moves demand. The second is that the most expensive mistakes on a South African commercial tariff come from half-hours you did not see coming.
Enertia takes those lessons and generalises them: one core that models each brand’s real levers, plans ahead against forecasts and tariffs, and runs on site. It is being built slowly and carefully, with each stage proven against a simulator and recorded site data before it touches live equipment.
Four rules we build by.
- 01
The site is the source of truth.
Datasheets describe what equipment should do. Telemetry shows what it actually does. Enertia is designed to learn from the telemetry.
- 02
Honest about limits.
When a target cannot be reached with the levers available, the system says so and does not report success it did not achieve.
- 03
Local first.
Control that depends on someone else’s cloud is only as reliable as that cloud. The loop lives on site.
- 04
Earn the right to write.
Shadow mode, a decision log and staged, reversible cutovers. Trust in a controller should come from evidence.
Put a site in the pilot.
We are looking for a small number of South African sites with solar, batteries or both, where tariffs and demand charges carry real money. Pilot sites run Enertia in shadow mode first: it plans and explains, and it controls nothing until you agree to switch it on.
