Zendure Smart Meter 1CT-S

Zendure Smart Meter 1CT-S – Precision Energy Monitoring for Your SolarFlow System

Unlock the full potential of your Zendure SolarFlow energy storage system with the Zendure Smart Meter 1CT-S. Designed specifically for single-phase residential setups, this advanced smart current monitor acts as the "eyes" of your home energy ecosystem, delivering precise, real-time data on your household's energy consumption, solar generation, and grid import/export.

By integrating the 1CT-S with your SolarFlow system, you transform a simple battery into an intelligent, automated energy management hub that maximises your savings and self-consumption.

Key Features & Benefits

📊 Precision Single-Phase Energy Monitoring

Equipped with a high-accuracy current transformer (CT) clamp, the 1CT-S continuously monitors the total power flow of your single-phase household. It provides granular, real-time data to the Zendure App, ensuring your system knows exactly how much energy your home is using at any given second.

🎯 Maximise Self-Consumption & Zero Export Control

Stop wasting your free solar energy! The 1CT-S enables advanced Zero Export functionality. By detecting surplus solar generation, it signals the SolarFlow battery to absorb the excess power before it is exported to the grid. This is crucial for households with strict grid export limits or those looking to maximise the financial return on their solar investment.

🧠 Seamless HEMS 2.0 Integration

The Smart Meter 1CT-S is the missing link for Zendure’s advanced Home Energy Management System (HEMS 2.0). It feeds critical data to the ZENKI™ 2.0 AI Agent, allowing the system to:

- Automatically optimise charge and discharge schedules based on real-time household demand.

- Seamlessly adapt to dynamic time-of-use (TOU) tariffs (e.g., Octopus Agile/Intelligent Go).

- Predict and manage energy flows for connected heat pumps or EV chargers.

🔌 Reliable & Stable Connectivity

Designed for uninterrupted performance, the 1CT-S features a built-in RJ45 Ethernet port for a stable, hardwired connection to your router or directly to the SolarFlow main unit. This ensures zero data lag and reliable communication, even in environments with weak Wi-Fi signals.

🛠️ Compact & Easy to Install

Sleek, lightweight, and designed for standard UK consumer units (distribution boards). The non-invasive CT clamp simply clips around your main incoming live wire, making installation straightforward and safe when performed by a professional.

Ideal For:

✅ Single-Phase Homes – Perfect for standard UK residential properties with a single-phase grid connection.

✅ SolarFlow Owners – Essential accessory to unlock HEMS 2.0, Zero Export, and AI-driven optimisation.

✅ Dynamic Tariff Users – Enables precise load matching to capitalise on cheap off-peak electricity rates.

✅ Grid-Constrained Properties – Prevents unwanted solar export where local DNO (Distribution Network Operator) rules require strict zero-feed-in limits.

⚠️ Important UK Installation Note

While the Zendure Smart Meter is designed for straightforward integration, installing the CT clamp inside your consumer unit (fuse box) involves working with live mains electricity. *This installation must be carried out by a Part P-qualified electrician** to ensure compliance with UK wiring regulations (BS 7671) and to maintain your system’s warranty and safety certifications.*
