Frequently Asked Questions
What is the Sungrow Smart Meter DTSU666-20?
The DTSU666-20 is a three-phase digital energy meter (Smart Meter) from Sungrow. It measures grid consumption and feed-in indirectly via current transformers and provides this data to the inverter for exact energy management. The set offered here includes the meter and 2 CT sets with a total of 6 current transformers of 100 A each.
Why is a Smart Meter needed in a PV system?
The Smart Meter continuously records how much electricity is drawn from the grid and how much is fed in. Based on these measurements, the inverter can optimize self-consumption, regulate feed-in (e.g., zero export), and switch on consumers as needed.
Why is the measurement indirect via current transformers?
With indirect measurement, the entire current is not passed through the meter, but is tapped via current transformers (CT). This enables the measurement of higher connection currents – here up to 100 A per transformer – with a compact design and easy retrofitting in existing distribution boards.
How is the DTSU666-20 mounted?
The meter, with a width of 4 TE (72 mm), is designed for DIN rail mounting in the distribution board. The six current transformers are clamped over the phase conductors and routed to the meter with the 6.0 m long connection cable – the installation is carried out by a qualified electrician.
