Custom WiFi Bidirectional Energy Meter Smart Solar Net Metering Power Monitor Wholesale OEM ODM Manufacturer Supplier Factory

This all-in-one design smart IOT device applied to AC110V or 220V/230V, 50/60Hz, rated current up to 63A single phase circuits in resident, commercial, and industrial buildings with 2.4G WiFi, is a bi-directional measuring two-way meter to measure both positive active energy consumption on grid and negative active energy from solar, and offers prepayment as an option; to remote control and set protections against over/under voltage, overcurrent, residual current (leakage), high It also offers local manual control without WiFi and voice control via the AI speaker, such as Amazon Alexa, Google Assistant, Yandex Alice, and etc.

Key Features & Capabilities

Four Options for Control

Remote control from anywhere (smartphone app, Tuya Smart, and Smart Life)
Voice control (AI speaker, Alexa, Google Assistant, Alice, etc.)
Timing Control (programmable schedule)
Manual control (by button)

Remote Monitoring

Get real-time voltage, current, and power data on your phone by connecting over WiFi to the Tuya App. This allows you to keep an eye on your home's energy consumption from a distance.

Bidirectional Metering (Core)

Bidirectional measurement of positive and negative active energy use. Ensures accurate revenue from electricity sales by carefully recording power delivered into the grid from PV generation or discharged from storage systems in addition to tracking your electricity use.

Safety Protection

In order to prevent appliance damage, it has overvoltage and undervoltage protection that automatically cuts power during voltage anomalies.

Overcurrent & Prepaid Metering

Overcurrent protection: 1–63A configurable, with 63A as default (alert disable option). The switch also offers prepaid metering as an optional mode.

High Current Capacity

It can easily manage high-power appliances like charging stations, underfloor heating, and central air conditioning without running the danger of overload tripping because to its 63A rated current.

Frequently Asked Questions (FAQ)

What is bidirectional energy metering and why is it important for solar systems?

Bidirectional metering measures both the energy consumed from the grid and the excess solar electricity exported back to the grid. This allows users to accurately calculate feed-in tariff revenues and balance energy generation with consumption.

Can I operate the device manually without an active Wi-Fi connection?

Yes. While 2.4G Wi-Fi enables app-based and voice control, the device also includes physical manual push buttons and an onboard LCD display with backlight for standalone operation.

Which smart home platforms and voice assistants are supported?

The device works natively with the Tuya Smart and Smart Life applications, and connects with AI voice assistants such as Amazon Alexa, Google Assistant, and Yandex Alice.

How does the overcurrent and voltage protection function?

Users can configure overvoltage (AC 230–300V), undervoltage (AC 80–210V), and overcurrent thresholds (1–63A). When abnormal electrical conditions occur, the unit automatically disconnects to protect connected appliances from damage.

How is the smart meter installed?

The meter is designed with a standard 35mm DIN-rail mount, making it compatible with standard distribution boxes and modular electrical panels in residential, commercial, or industrial applications.
