Frequently Asked Questions

Common questions from mining operators and industrial companies before working with VoltVision.

Does installation require a shutdown?+

No. Our V-CUBE hardware is a plug-and-play IoT gateway that connects to your existing metering devices without requiring equipment replacement or scheduled downtime. Most sites are live within days.

What does Zero CAPEX mean?+

VoltVision is delivered as a licensed service with no upfront capital expenditure. No hardware purchase, no infrastructure investment, no large setup cost — you pay an accorded operational fee and we handle everything else.

What meters and equipment do you connect to?+

Our technology is hardware-agnostic. V-CUBE connects to any metering device — digital or analogue — across your HV and MV network, regardless of manufacturer or age. We have experience with Siemens, ABB, Schneider, GE and many others.

Is our data secure?+

Yes. V-CUBE uses a one-way data link between your industrial network and the cloud, eliminating any risk of a cyber breach back into your operational systems. Tested to IEC 61850 standard and CISPR 22 compliant.

How quickly will we see results?+

Most clients identify actionable insights within the first weeks of going live. One Tier 1 mining client achieved ROI within one month and identified over $1M in billing errors in the first year.

Do you work outside Africa?+

Yes. While we predominantly operate across Africa — which represents the first stage of our global development — VoltVision's solutions are deployed worldwide. We are headquartered in Harwell, Oxford (UK) and operate a global power analytics centre in Johannesburg, South Africa.
