Sigenergy Sigen Power Sensor TP-DH (1426000003) – 3-phase energy meter

The Sigenergy Sigen Power Sensor TP-DH is a 3-phase energy meter within the Sigenergy SigenStor ecosystem. This meter measures in real time how much power the home draws from the grid (import) and how much energy is fed back (export), across all three phases.

The measured data is sent on to the Sigen Energy Controller TP series or Sigen Hybrid TP2 inverter. Based on this grid measurement, the system determines when the battery should charge or discharge.

What does the TP-DH energy meter do?

• Measures grid import per phase
• Measures grid export per phase
• Supplies real-time measurement data to the Sigenergy controller
• Enables accurate battery control
• Supports self-consumption and power control

Why is this sensor essential?

In 3-phase installations, phase balance is crucial. The TP-DH ensures the system knows exactly what is happening on each phase, so that:

• surplus PV is correctly directed to the battery
• the battery discharges during grid import
• the system operates stably and efficiently
• any power limits are respected

Compatibility

• Sigen Energy Controller TP series (3-phase)
• Sigen Hybrid TP2 (3-phase)

Please note: this TP-DH version is intended exclusively for 3-phase installations. For 1-phase systems, use the SP-DH variant.

Technical data

Installation tips

• Ensure correct positioning in the grid measurement according to the installation guidelines.
• After commissioning, check that import/export per phase is displayed correctly.
• Incorrect phase connection can lead to faulty battery logic.
• Always test charging and discharging behaviour at handover.
