The meter
DIY solar
actually needs.

ClaroWatt Pro is a DIN rail AC power meter purpose-built for US split-phase residential grid-tie solar — the product the OEM kit should have shipped with.

OEM limiter meters
fail US installs by design.

Every grid-tie inverter with a limiter port ships with a meter that was never built for the US residential electrical system.

Single-Phase Blind

OEM meters read only one leg of US split-phase 120/240V power. Half your load is invisible — net export math is wrong from day one, causing inverter over-export or unnecessary throttling.

Bare-Wire Installation

Requires cutting live AC conductors to install. Not installer-friendly, not safe for DIY, and not code-compliant in most US jurisdictions.

Zero Configuration

Fixed firmware. No protocol selection, no response tuning, no inverter count setting. One size fits nobody in a real residential installation.

Proprietary Lock-In

Single-protocol output only — no Modbus RTU. Can't integrate with Home Assistant, ESPHome, or any third-party monitoring platform.


ClaroWatt Pro.
What the kit
should have shipped with.

Production-ready hardware on a validated analog front end. JLCPCB SMT assembled. Gerbers on file.

True Split-Phase Measurement

Dual CT inputs, 100A/50mA secondary. Reads both 120V legs simultaneously for accurate 240V net export on every install.

DIN Rail Form Factor

72×72mm standard panel housing. Snaps into any enclosure. CTs clamp over existing conductors — no wire cutting.

Dual Protocol Output

RS-485 proprietary or Modbus RTU — user-selectable at configuration time, no firmware flashing required.

Live Watt Display

0.56" 4-digit 7-segment LED. Net watts offset from zero. Updated every 3 seconds in sync with RS-485 transmit.

USB-C Powered & Programmed

Single connector for power and firmware updates. No proprietary tools, no separate programmer required.

Per-Unit Serial Programming

Configuration locked to customer spec at time of order. Ships ready for the installation it was built for.
