Step 01
Monitor dimensions and antenna placement
The monitor is 111.3 × 81.2 × 41.4mm and supports DIN-rail mounting. The external antenna belongs outside the metal panel to avoid signal obstruction.

WattPanel-3X
Main CTs or circuit CTs?
- 01
Main CTs and branch channels
WattPanel-3X uses three main CTs for the supply and supports up to 16 individual circuit channels. A main-only bundle does not include those circuit sensors; choose the bundle for the circuits you want to measure.
- 02
WiFi connection
The monitor uses 2.4GHz WiFi (802.11 b/g/n). A 5GHz-only network is not supported.
- 03
Measured electricity, not an automatic bill saving
Consumption and production readings help you review electrical usage. Cost also depends on your tariff; purchasing a monitor does not establish a reduction in usage or bills.
Product role
Consumption and production are separate readings.
Review energy consumed and energy produced over time. Whole-home totals and individual circuit readings answer different questions; a supply total alone does not identify every appliance.
- Main channels
- Readings for the electrical supply
- Branch channels
- Readings for the individual circuits covered by the installed Sub CTs
- History
- Compare recorded consumption and production across time

Use the scene to understand placement and everyday interaction, not as proof of compatibility.
Before you choose
Qualified installation, with the exact service verified.
Not every three-phase connection is supported. Have a qualified electrical professional verify the service arrangement against the manual. Service mains remain live even with the main breaker off; this is not a DIY installation or a billing-meter substitute.
- Have the installer identify the electrical service from the equipment documentation, not from the product name.
- Match the selected Main CT rating and included Sub CTs to the intended measurement channels.
- Request the WattPanel-3X manual for the selected bundle before arranging installation.
Guides and answers
Find the detail you need before ordering.
Does every bundle include 16 circuit sensors?
No. The monitor supports up to 16 circuit channels, but included Sub CTs depend on the chosen bundle. Compare the bundle names and SKU above rather than assuming the maximum channel count is the box contents.
Are these specifications an independent accuracy test?
No. The product specifications describe capabilities. This page does not provide an independent measurement-accuracy report or a verified bill-savings study.
