Our opinion

The buying view.

EDITORIAL OPINION - BASED ON THE CITED RESEARCH

“Compare the installed total with the matching Zen sensor and a Type 2 lead. Confirm what your car can draw before paying for a 22 kW circuit.”

Observed hardware price: $999 before professional installation.
Installation planning range: About $800–$1,500 for straightforward work; commonly $1,500–$3,000+ with longer runs, upgrades or strata complexity.

Cons and watch-outs

What to verify.

A separate Zen sensor kit is required for the documented solar and household load controls.
Confirm firmware and provider compatibility for a third-party OCPP endpoint.

Ask the installer to identify the exact model, protection, CTs/meters, cable route, commissioned current and energy-platform compatibility in writing.
