Self-consumption
Your battery finally follows your actual consumption
Without a meter, a solar battery delivers a fixed output, whether it is useful or not. The Smart Meter 1CT-S continuously measures what enters your home. Your SolarFlow then adjusts its discharge in real time: the stored energy powers your appliances instead of being sent back to the grid.

Connectivity
Reliable communication, whatever your Wi-Fi connection
Is your electrical panel far from your router? Connect the meter via Ethernet or RS485 for stable wired communication. 2.4 GHz Wi-Fi and Bluetooth are also available for quick commissioning from the app.

Compatibility
The brain of your Zendure ecosystem
The Smart Meter 1CT-S works with Zen+ OS, the energy management system (HEMS) integrated into the SolarFlow 2400 AC+, 2400 Pro and 800 Plus. Control takes place locally, with a fast response time and no dependence on an Internet connection.

Your questions answered
« Is it compatible with my Zendure battery? »
The Smart Meter 1CT-S is designed for systems equipped with Zen+ OS: SolarFlow 2400 AC+, SolarFlow 2400 Pro and SolarFlow 800 Plus. For another model, our team can check compatibility with you on 04 83 58 04 79.
« Can I install it myself? »
The meter is installed on a DIN rail and the clamp clips around the incoming cable without cutting it. The work is carried out in the electrical panel: always switch off the main circuit breaker before starting. If in doubt, have it installed by an electrician — it only takes a few minutes.
« My Wi-Fi signal is weak near the electrical panel. Is that a problem? »
No. The 1CT-S offers a wired Ethernet or RS485 connection, independent of your Wi-Fi quality. Thanks to Zen+ OS, control remains local and continues to work even if the Internet connection is interrupted.
« Can I also measure the production of another solar installation? »
The 1CT-S is supplied with a 120 A clamp, ideal for measuring the grid supply to a home. If you want to monitor several measurement points, the Smart Meter 3CT-S, supplied with 3 clamps, is better suited to your needs.
