Frequently Asked Questions
What is the Sofar Smart Meter DTSU666?
The Sofar DTSU666 is a 3-phase energy meter (Smart Meter) that directly measures power consumption and feed-in of a PV system up to 80 A per phase. Via the RS485 interface, it delivers these measured values to the inverter, thus forming the basis for self-consumption optimization and zero export.
For which systems is direct measurement up to 80 A suitable?
Direct measurement without external current transformers is suitable for household and smaller commercial systems where the current per phase does not exceed 80 A. For higher connection capacities, a meter with current transformer measurement is used instead.
How is the DTSU666 mounted and connected?
The meter is housed in a compact 4-module (72 mm) enclosure and mounted directly on the DIN rail in the distribution board. The connection is 3-phase at 400 V / 50 Hz, and data transmission to the inverter is via RS485.
Why do I need a Smart Meter in the PV system?
The Smart Meter records how much electricity is fed into the grid and how much is consumed. The inverter needs this data to maximize self-consumption, control excess charging of a storage unit or wallbox, and – where required – limit feed-in power.
Who is Sofar?
Sofar (Sofar Solar) is an international manufacturer of inverters, storage systems, and PV accessories. The product range extends from grid-tied and hybrid inverters to meters and monitoring components for private and commercial solar systems.
