Payment
You can pay for your order by bank transfer, in HUF or EUR. We will send you a payment request via email, which includes the necessary data for the transfer. If you would like a unique payment method (for example, cash or cash on delivery), select the “Unique payment plan” option and our colleagues will contact you to discuss the details.


Transport
The shipping fee depends on the size and type of the ordered product. For smaller packages, the home delivery fee is 3,790 HUF, for larger products it is 6,490 HUF. For solar panels, batteries and other large products, the delivery is based on an individual price quote, which our staff will always discuss with you after placing the order.

Huawei DTSU666-HW is a three-phase smart meter that measures the consumption and production of the solar system in real time and then transmits the data to the inverter and monitoring system. This gives an accurate picture of how much electricity the building consumes, how much is produced, and how much is fed back into the grid.

The device is compact, DIN-rail mountable, and operates with low power consumption. Its LCD display is easy to read and communication is via RS485 (Modbus-RTU) protocol, ensuring reliable connection with Huawei inverters.

This model is designed for three-phase networks and measures up to 80 A directly, but can also measure higher currents with an external current transformer. It is therefore recommended for buildings or systems where the current per phase remains below 80 A, or where a higher measurement range is required with an external CT.

Main features:

• Real-time measurement of consumption, production and grid regeneration
• High accuracy measurement class (Class 1)
• For three-phase networks (0–80 A direct measurement, external CT for higher currents)
• LCD display for easy data checking
• RS485 communication (Modbus-RTU) with Huawei inverters
• Low power consumption (≤1.5W)
• Compact, DIN-rail mountable design
