Frequently Asked Questions

A smart current transformer for energy monitoring that uses LoRa or RS485 communication to transmit real-time power consumption data to compatible Deye inverters. It supports zero-export control, smart load management, and accurate home energy monitoring without running long communication cables through your home.

It depends on your connection mode. For LoRa wireless mode, you need the SUN-SMART-TX01 Smart Transmitter connected to your inverter. For RS485 wired mode, the CT connects directly to the inverter via cable — no additional equipment needed.

Up to 200 meters via LoRa communication in open space. The signal is capable of penetrating multiple walls, making it suitable for installations where the meter box is far from the inverter.

Both single phase (L1/N) and three phase (L1/L2/L3/N) configurations. For three-phase systems, multiple CT clamps measure each phase independently for precise energy monitoring.

The Wireless CT enables three key functions: zero-export control (prevents feeding energy back to the grid), energy monitoring (tracks household consumption in real-time), and smart load management (optimizes when devices run based on solar availability).

Yes. Certified to AS/NZS 61010.1 safety standards for the Australian market. The device meets all local regulatory requirements, including RCM compliance, for measurement equipment used in residential solar installations.

The CT provides high-precision current sensing with real-time data transmission at 1-second intervals. This fast refresh rate ensures accurate zero-export control and responsive load management.

Yes. LoRa technology provides strong wall penetration for reliable indoor-to-outdoor communication. The signal is suitable for typical residential and light commercial building layouts where the meter box is not next to the inverter.

Compatible with Deye hybrid inverters that support LoRa or RS485 communication. Final compatibility depends on the inverter model, system design, and local product availability in your market.

Non-invasive clamp-on installation — simply clamp the CT around the main power cable at your meter box. No wire cutting required. The entire installation typically takes under 10 minutes and does not require a qualified electrician.

5/5

No more running cables through the house. The wireless connection to the inverter is stable, even through walls, and the setup was quick and clean.

Verified customer Residential solar user
5/5

Works reliably from the meter box to the inverter. A neat solution when wired RS485 installation would be difficult.

Verified customer Home energy user
5/5

Useful for zero-export setup. The response is fast, the readings are clear, and wireless communication made the installation much easier.
