Multi-Tenant Sub-Metering Precision

Global property developers and commercial high-rises necessitate IEC 62053-21 Class 1.0 certified sub-metering switches. With individual breaker-level monitoring, landlords eliminate utility leakage, generate automated audit invoices, and resolve multi-occupant power friction with zero manual meter reads.

PV Solar & Storage Bi-Directional Flow

Microgrid operators require smart switches capable of instant reverse current identification and Net-Metering edge telemetry. Our micro-switches track grid export versus local battery storage charging in real-time, executing localized trip or bypass commands under variable distributed generation constraints.

Grid Peak Lopping & Automated DR

Utility service suppliers integrate smart meter switches within automated Demand Response (OpenADR 2.0b) networks. In the event of grid frequency drift or peak capacity constraints, industrial loads (HVAC, EV chargers) are autonomously shifted or disconnected via millisecond magnetic latching.

Macro Application Framework

Commercial, Industrial & Infrastructure Solutions

Turnkey power distribution topologies deployed across advanced facilities, industrial complexes, and EV infrastructure.

EV Infrastructure & Dynamic Balancing

Fleet operators face strict current thresholds. Our intelligent energy switches continuously measure total building consumption against transformer capacities, dynamically allocating remaining bandwidth to Level-2 and Level-3 DC fast chargers to prevent utility demand penalties.

Telecom Base Stations & Remote Sites

Remote telecommunication infrastructure requires complete off-site autonomous maintenance. Our 4G Cat-1/NB-IoT smart breakers support scheduled power cycling, predictive thermal drift trips, and battery back-up failover routing with real-time MQTT push logs.

Smart Hospitality & Build-to-Rent (BTR)

High-density residential and hospitality projects install Corunsmart smart switch panels and micro-breakers to centralize keycard management, automate vacant unit low-power profiles, and isolate water leakage zones before physical structural damage occurs.

Technical Clarifications

Frequently Asked Questions

Essential procurement, engineering, and manufacturing specifications for prospective commercial partners.

What specific metering precision and energy parameters do your smart switches support?
Our smart sub-metering line utilizes dedicated high-precision energy measurement chipsets achieving IEC 62053-21 Class 1.0 accuracy (±1.0% error or better across active range). Monitored real-time parameters include Active Power (kW), Reactive Power (kVAR), Voltage RMS (V), Current RMS (A), Frequency (Hz), and Total Cumulative Energy (kWh) with bidirectional forward/reverse tracking for PV systems.
Can Corunsmart deliver private label firmware outside the Tuya cloud ecosystem?
Yes. Beyond standard Tuya Smart Life and Tuya-Matter platforms, we specialize in OEM deliveries featuring open-source or custom firmware. We supply smart breakers and modules based on Espressif ESP32, ESP32-C2, and ESP32-C3 platforms pre-configured with Tasmota, MQTT, ESPHome, or custom customer-supplied binaries with secure boot and flash encryption enabled.
What over-current and leakage trip mechanisms are implemented inside the smart breakers?
Corunsmart smart circuit breakers integrate hybrid electromechanical and electronic safety circuits. They provide double-cut physical disconnection of both Live and Neutral (L+N) conductors simultaneously. Residual current devices (RCD) feature adjustable trip thresholds (10mA - 100mA) with rapid magnetic latching operating within 0.04 seconds during short circuits or earth leakage incidents.
What is your production lead time, MOQ, and sample dispatch schedule?
Evaluation samples of standard OEM products ship within 3–5 working days. Customized firmware or laser-engraved prototype samples take approximately 7–10 days. Standard production batch runs have an MOQ of 500 to 1,000 units with an average 25–30 day factory turnover, backed by our monthly capacity of 400,000 finished units.
How does Corunsmart guarantee international regulatory compliance for customs clearance?
Our facility maintains active ISO 9001:2015 and BSCI operational certifications. All product families hold verified CE (LVD/EMC), RoHS, FCC, and UKCA marks. Models targeted for the North American market hold ETL or UL compliance certificates. Full test reports and DoC (Declaration of Conformity) files are provided directly to client compliance teams prior to bulk transit.
