Zendure 3CT-S three-phase smart meter for SolarFlow batteries
Measure your consumption in real time across all 3 phases and let Zen+ OS control your SolarFlow battery to the nearest watt, for solar self-consumption without waste.
Three-phase measurement · Watt-level adjustment · Zero waste
3 three-phase CT clamps
Up to 120 A per channel
1 W adjustment accuracy
2.4 GHz Wi-Fi + Bluetooth
Compatible with SolarFlow & Hyper
Consumption < 3 W
3-CT three-phase measurement
3 independent current clamps, up to 120 A per channel, to read each phase separately.
Watt-level adjustment
Your battery delivers exactly what you consume, in 1 W increments — without unnecessary injection.
Zen+ OS, even offline
Local meter → battery communication: control remains responsive without an Internet connection.
Scheduling and timer
Schedule charging and discharging according to your timetable or your contract's off-peak hours.
Real-time monitoring in the app
Live consumption and usage history from the Zendure app, wherever you are.
Overload protection

Accuracy
Your battery follows your consumption in real time
The 3 CT clamps measure the current on each phase of your home, up to 120 A per channel. Zen+ OS sends this measurement to your SolarFlow, which adjusts its output power in 1 W increments. You use your own stored energy instead of injecting it into the grid for free.

Installation
Four steps at the electrical panel
Switch off the main circuit breaker, clip the clamps onto the conductors upstream of the panel while observing the indicated direction, then mount the compact housing (91 x 36,5 x 64 mm), powered by 100-240 VAC. Pairing is then completed from the Zendure app. In single-phase installations, the 3 clamps must be bridged on the same phase: we recommend using a qualified electrician.

Compatibility
The brain of your Zendure ecosystem
The 3CT-S (ZDSMCT model) integrates with the Zen+ OS ecosystem, including SolarFlow 2400 AC and Hyper 2000. The SolarFlow Mix range also recognises it via RS485 or Wi-Fi. Check exact compatibility with your model before purchase.

Reliability
Control continues, even without the Internet
Most connected systems rely on the cloud. With Zen+ OS, the meter communicates directly with the battery locally. If your connection goes down, regulation remains active; the app is used for monitoring and scheduling.

Your questions answered
« I have a single-phase installation — is this meter suitable for me? »
Yes. In a single-phase installation, the 3 clamps must be bridged on the same phase for reliable measurement. This is the key installation point: ideally have it handled by an electrician, or call our team on 04 26 91 10 72.
« Is it compatible with my Zendure battery? »
The 3CT-S works with the Zen+ OS ecosystem, including SolarFlow 2400 AC and Hyper 2000. The SolarFlow Mix range recognises it via RS485 or Wi-Fi. If you are unsure about your model, contact us before ordering.
« What if my Internet router goes down? »
Battery control continues. Zen+ OS provides direct local communication between the meter and the battery. Only remote monitoring and settings via the app will wait until the connection is restored.
« What is the difference compared with the Zendure 1CT meter? »
The 1CT measures a single phase with one clamp. The 3CT-S measures all 3 phases separately, up to 120 A per channel. It is recommended for three-phase homes, or for more precise measurement in single-phase installations.
