Spot cross-mated MC4 connectors before they start a fire

Pricing

Aerial IR finds the fever. ConnectorCheck diagnoses the disease. When a thermal scan flags a hot connector — or your tech just doesn’t like the look of a coupling — one phone photo returns an engineering verdict: visibly cross-mated or not, why it matters, what the code says, and what to do about it.

Why “coming soon”? Because we do this in the right order.

The detection model was trained on a controlled six-brand laboratory matrix of correct, cross-mated, unmated, and thermally damaged MC4-style couplings. Paid plans open after field validation at an operating utility-scale plant — when we can publish real precision and recall numbers instead of asking you to trust a demo. That’s how an engineer sells an engineering tool. Leave your email on the analyzer page and you’ll get the field numbers and launch pricing the day they’re out.

Scope: visible cross-mating, unmated couplings, and visible thermal damage on MC4-style connectors, from close-up RGB photos. Some cross-mating presents no visible cue — no photo tool can see it, and we say so. ConnectorCheck is advisory and does not replace a qualified-person inspection under NFPA 70E / NEC.
