Learn step-by-step how to pair the Zendure Smart Meter 1CT-S with your SolarFlow system for accurate energy monitoring and smarter solar management.
If you’ve recently invested in a Zendure SolarFlow system, you’re already on the path to energy independence. But to truly optimize your solar generation and consumption, you need accurate, real-time data. That’s where the Zendure Smart Meter 1CT-S comes in. This compact device measures the energy flowing through your home’s electrical panel, allowing your SolarFlow system to intelligently manage power based on your actual usage patterns.

In this guide, we’ll walk you through the entire pairing process—from unboxing and physical installation to connecting the meter to the Zendure app and verifying the connection. Whether you’re a first-time user or upgrading an existing setup, these clear steps will ensure your Smart Meter 1CT-S works seamlessly with your SolarFlow system, helping you maximize savings and efficiency.
Why Pair a Smart Meter with Your SolarFlow System?
Pairing a smart meter like the Zendure Smart Meter 1CT-S with your SolarFlow system unlocks advanced features that go beyond basic solar generation. The meter tracks real-time energy consumption and grid import/export, enabling your system to prioritize solar power, charge batteries during off-peak hours, and even sell excess energy back to the grid when it’s most profitable.
Without a smart meter, your SolarFlow system operates on a fixed schedule or manual settings, which often leads to wasted solar energy or unnecessary grid reliance. With the 1CT-S, you get dynamic load management—your system automatically adjusts based on your household’s energy needs. This is especially valuable for users with a Zendure SolarFlow 2400 Pro or a Zendure SolarFlow 1600 AC+, as it ensures you get the most out of your solar investment.
- Real-time energy monitoring: See exactly how much power your home consumes and produces.
- Smart charging: Automatically charge your battery when solar generation exceeds usage.
- Grid optimization: Export surplus energy when feed-in tariffs are highest.
What You’ll Need Before Starting
Before you begin, gather the following items to ensure a smooth setup: your Zendure Smart Meter 1CT-S, a compatible SolarFlow system (such as the SolarFlow 2400 Pro or SolarFlow 1600 AC+), a stable Wi-Fi connection, and the Zendure app installed on your smartphone. Also, ensure that your home’s electrical panel is accessible and that you have basic knowledge of electrical safety—if you’re uncomfortable, consult a licensed electrician.
The Smart Meter 1CT-S is designed for easy installation, but it does require connection to your main electrical panel. For most users, this involves clipping the current transformers (CTs) around the main power lines and connecting the meter’s communication cable to your SolarFlow hub. If you’re using a Hub 1200 or a Hub 2000 + SuperBase V Plug and Play Solar System, the process is similar—just locate the designated port on the hub.
- Zendure Smart Meter 1CT-S
- Compatible SolarFlow system (e.g., SolarFlow 2400 Pro, SolarFlow 1600 AC+)
- Zendure app (latest version)
- Stable Wi-Fi (2.4 GHz recommended)
Step-by-Step Pairing Instructions
First, physically install the Smart Meter 1CT-S. Turn off the main breaker to ensure safety. Open your electrical panel and attach the CT clamps around the main incoming power lines, following the direction arrows. Connect the meter’s wiring to the designated communication port on your SolarFlow hub (e.g., the Hub 1200 or the hub included with the SolarFlow 2400 Pro). Once connected, power everything back on.
Next, open the Zendure app on your smartphone. Navigate to the 'Devices' section and tap 'Add Device.' Select 'Smart Meter' from the list and choose '1CT-S.' The app will prompt you to scan for nearby devices—make sure your phone’s Bluetooth is enabled. Once the meter appears, select it and follow the on-screen instructions to connect it to your Wi-Fi network. Use a 2.4 GHz network for the most stable connection.
After the meter connects, the app will automatically sync it with your SolarFlow system. You may need to enter your home’s grid settings (e.g., feed-in tariff) to enable advanced features. Finally, verify the connection by checking the app’s dashboard—you should see live data for energy consumption, solar production, and grid import/export. If the data doesn’t appear, restart the app or reboot the hub.
- Always turn off the main breaker before handling electrical wiring.
- Ensure the CT clamps are oriented correctly (arrows pointing toward the load).
- Use a 2.4 GHz Wi-Fi network for reliable communication.
Troubleshooting Common Pairing Issues
If you encounter issues during pairing, don’t worry—most problems have simple fixes. If the meter isn’t detected by the app, check that it’s powered and that the communication cable is securely connected to the hub. Also, ensure your phone is within range and that Bluetooth is enabled.
If the meter connects but shows inaccurate readings, double-check the CT clamp orientation. Reversing the clamps will result in negative or inverted values. Additionally, verify that the CT clamps are securely closed around the wires and not loose. If the app still shows no data, try restarting the hub and the meter, then re-scan in the app.
For users with multiple SolarFlow devices, such as a Zendure Battery AB3000L or an 450W Bifacial Solar Panel, ensure that the meter is paired to the correct hub. In the app, you can assign the meter to a specific system under the 'Settings' menu. If problems persist, consult the Zendure support team or refer to the official manual.
- Check CT clamp orientation if readings are inverted.
- Restart the hub and meter if no data appears.
- Assign the meter to the correct hub in the app if you have multiple systems.
Maximizing Your SolarFlow System with the Smart Meter
Once your Smart Meter 1CT-S is successfully paired, you can unlock the full potential of your solar setup. Use the app’s insights to adjust your energy consumption habits—for example, run heavy appliances during peak solar production hours. You can also set up automations, such as charging your battery only when solar generation exceeds a certain threshold.
The smart meter also enables net metering, allowing you to track exactly how much energy you export to the grid. This is especially beneficial if you have a plug-and-play system like the Balcony Easy Solar Bracket or a Zendure 400W Portable Solar Panel—you’ll know precisely when to use power and when to sell it back. By leveraging this data, you can reduce your electricity bills and increase your return on investment.
- Set automations to charge batteries during peak solar hours.
- Track export earnings to optimize feed-in tariffs.
- Use historical data to adjust your energy usage patterns.
Pairing your Zendure Smart Meter 1CT-S with your SolarFlow system is a straightforward process that brings significant benefits. With real-time data and intelligent automation, you’ll not only save money but also contribute to a greener planet. If you haven’t yet upgraded your solar setup, consider exploring the Zendure SolarFlow 2400 Pro to experience the full potential of smart solar energy management.
