Smart energy control for the off-grid EV charging station - South Africa

As EV adoption accelerates, charging infrastructure is
expanding into locations where grid access is limited
or unavailable.

To address this challenge, Zero Carbon
Charge, in collaboration with Elum Energy, worked
together to deliver modern off grid stations along N3
(Johannesburg – Durban) to coordinate multiple
energy assets to enable reliable, high-performance,
and sustainable EV fast charging.

ePowerControl EV provides the following functions:

• Operates BESS in Prime Mode, using the
  battery as the primary power source.
• Automatically manages generator start/stop
  based on battery SoC and site demand.
• Monitors Modbus-compatible EV charging
  stations in real time.
• Coordinates the operation of the BESS,
  generator, and EV chargers to ensure stable
  power delivery.
• Provides centralised monitoring of energy
  flows, battery performance, generator status,
  and charger operation.
• Optimises PV utilisation while reducing
  generator runtime and operating costs.
