HomeKit Three-Phase (Smart Meter) GoodWe HK3000

The HomeKit HK3000 is a three-phase smart meter with three 120 A current transformers (CT) that records real-time household consumption and energy flows between the grid and inverter. It sends data to the cloud every ~60 seconds via a Wi-Fi/LAN module and, when used with compatible GoodWe inverters, enables export power control to comply with regulations and maximize self-consumption.

Main Features

• Triple CT design for simultaneous measurement on grid and inverter.
• 24/7 monitoring with cloud storage and visualization.
• Export limitation when integrated with GoodWe inverters.
• Integrated communication: Wi-Fi/LAN; data updates every ~60 s.
• Non-invasive installation: clamp-on CTs for L1/L2/L3, no conductor cutting required.
• Compatible with the GoodWe ecosystem for load reading and net metering.

Electrical and Environmental Specifications

• System: three-phase 3×230/400 V; 50/60 Hz.
• Included CTs: 3 × 120 A (typical output 40 mA).
• Measurement range: from ~0.5 A up to 120 A per phase.
• Sending frequency: ~60 s to the cloud platform.
• Operating temperature: −25 °C to +60 °C.

Dimensions and Weight

• Device dimensions: 67 × 72 × 85 mm.
• Weight: ~0.50 kg.

Recommended Applications

• Three-phase residential self-consumption requiring 24/7 visibility.
• Export limitation/management to meet grid requirements.
• Load optimization, phantom load detection, and energy savings.

Installation and Best Practices

• Install CTs on L1, L2, and L3 (not on neutral), ensuring correct current direction.
• Place the device in a ventilated electrical panel with maintenance access.
• Check network signal and register the device in the GoodWe app/platform.
• If using export limitation, complete pairing with the inverter.

With the HK3000, you get reliable, connected three-phase measurement that provides accurate data to save, comply with regulations, and optimize self-consumption in residential installations with GoodWe inverters.
