IEMTR-2CH-CT100

Two circuits metered from one DIN-mounted unit, each through its own 100 A clamp. Bidirectional, so generation and consumption both read correctly, and reporting over Wi-Fi to the platform without a gateway in between.

What it is

Two circuits, one unit, no gateway in between

A compact DIN-mounted meter that clamps onto two circuits and reports straight to the platform over Wi-Fi. Useful where a solar feed and a load need watching on the same board.

  1. Meters two single-phase circuits from one shared voltage reference
  2. Clamps on, so the circuit does not have to be broken to install it
  3. Reads bidirectionally, so export and import are both signed correctly
  4. Reports over 2.4 GHz Wi-Fi with no gateway needed in between
  5. Takes firmware updates remotely once it is on the platform

One two-channel meter with a clamp on the solar inverter's output and another on the consumer unit, reporting both over Wi-Fi through an IESG-R250. It is bidirectional, so export shows as a negative on the generation channel without any configuration.
Scenario 01 · solar and load

See self-consumption, not just generation

Clamp one channel on the inverter output and the other on the incomer. The difference between them is what the building used from its own roof, and that is the number an installer's customer actually asks for.

Scenario 02 · two circuits, one point

Meter two feeds without two meters

Two sub-circuits leaving the same board, a workshop and an office say, can share a unit. Both channels reference the same voltage, so it suits split loads on one phase rather than two separate supplies.

for billing use IEMTR-EM165-W instead
Scenario 03 · short install window

Fit on a live circuit

The clamps open, so the meter goes on without isolating anything during a short visit. It is the one to choose when a fiscal-grade reading is not required and the time on site is tight.

Branding and finish

Your logo and product name on the housing and the packaging, and your details on the setup portal an installer sees.

Software and firmware

Custom firmware for whatever the two channels have to mean on your site, and a dashboard on your domain rather than a generic portal.

Documentation and support

Installation and clamp-orientation guides in your name — the two things that get fitted backwards on site if nobody writes them down.
