Aituzero Digital Sub Meters – ANSI Form 2S, 120/240V Single-Phase kWh Submeter for Rentals & RVs

Effortless energy visibility for rentals, RVs, and small facilities

The Aituzero Digital Sub Meter is a compact, plug‑in energy monitor designed for 120/240V single‑phase systems. Its ANSI form 2S compatibility lets you install it quickly in standard socket bases, making upgrades straightforward for RVs, garages, and workshop spaces without specialized tools.

Real‑time insights start with a bright LCD that clearly displays kWh usage, current draw, and voltage. This device is built for sub‑metering, helping you allocate electricity fairly across tenants, workshops, RV pads, or small apartments. Its solid‑state design and EEPROM memory deliver stable readings and data continuity even when power moments occur, supporting sensible billing and ongoing monitoring across diverse loads.

Key advantages at a glance

• Easy installation in standard 2S sockets with labeled terminals; quick snap‑in fit and status LEDs confirm correct wiring.
• Sub-metering tailored for fair billing and precise usage tracking across multiple circuits or tenants.
• Pulse output and Modbus communication enable seamless integration with existing monitoring or automation systems.
• Solar monitoring mode reveals import/export and flow trends, helping evaluate panel performance and balance loads.
• Durable sealed housing and solid‑state electronics designed to withstand varying environments.
• EEPROM memory preserves essential usage data through power cycles for reliable long‑term tracking.

Ideal use cases and real‑world scenarios

• Rental properties: monitor and allocate electricity usage for transparent billing and fair charges.
• RV parks and mobile setups: gain visibility into power consumption across pads and sites.
• Small workshops, garages, and outbuildings: track loads from tools, heaters, and chargers.
• Solar or hybrid systems: observe real‑time import/export to inform system sizing and upgrades.

What you get and how it helps

Clear, actionable data supports better energy planning, cost control, and equipment sizing. While the meter highlights possibilities for optimization, results depend on your specific installation and usage patterns. The device is designed for long‑lasting reliability in residential and light industrial settings, with easy monitoring and minimal disruption during upgrades.
