New energy meters from YADA Electronics — a Guangdong-based manufacturer (Beijing Stock Exchange: 920556) building smart power sensors and data loggers for distributed solar PV, inverter feedback control and renewable-energy monitoring. This category holds 4 models covering single-phase and three-phase installations up to 250 A via external CT, with CE, UKCA, RCM and MID certifications.
Export Limitation Is The Real Job
On a distributed PV site the meter is rarely there just to count kilowatt-hours. It is the feedback element that tells the inverter how much the site is exporting so that generation can be curtailed to the grid operator’s limit. That makes the communication interface and the update path as important as the accuracy class — a meter that reads perfectly but cannot reach the inverter is useless for this duty.
| Model | Configuration | Communication | Best Suited To |
|---|---|---|---|
| YDS60-2P | Three-phase, 3P4W / 1P2W, Imax 3×250(300) A | RS-485, WiFi, Bluetooth | Solar PV inverter feedback where wiring back to the inverter is impractical. |
| YDS70-C16 | Single-phase with CT input | RS-485 | Distributed rooftop PV, compact modular installations. |
| YDS60-C24 | Three-phase, up to 250 A external CT, 90–500 V | RS-485 Modbus | Commercial PV where CE / UKCA / RCM conformity is required. |
| YDS60-80 | Three-phase, Class 0.5 / 1.0 | RS-485 Modbus RTU | Distributed generation needing MID-grade accounting. |

Typical Applications
- Distributed rooftop PV — the YDS70-C16 is designed specifically for this duty.
- Commercial solar with export limitation — meter feeds the inverter so generation is curtailed to the permitted export.
- Hybrid PV plus storage — site-level import/export accounting.
- Renewable-energy monitoring platforms — Modbus data into cloud or SCADA reporting.
- Markets requiring documented conformity — CE, UKCA and RCM cover EU, UK and Australia / New Zealand.
How To Select A New Energy Meter
- Confirm the grid configuration — 3×230/400 V or 3×400 V, and whether a neutral is present.
- Establish the maximum site current and whether external CTs are needed.
- Decide how the meter reaches the inverter. RS-485 where cabling is possible; WiFi or Bluetooth where it is not.
- Set the accuracy class. Class 1 is adequate for control feedback; Class 0.5 where the reading is billed.
- Check the market conformity list — RCM for Australia and New Zealand, UKCA for the UK, CE for the EU.
Frequently Asked Questions
Which model works when the meter cannot be wired to the inverter?
The YDS60-2P supports RS-485, WiFi and Bluetooth, so the metering point and the inverter do not need a physical data run between them.
Can these meters be used for export limitation?
Yes — that is their primary duty on distributed PV. The meter reads site import/export and passes it to the inverter, which curtails generation to the permitted limit.
What is the difference from a standard AC energy meter?
These are built around the PV and inverter use case: CT inputs sized for rooftop arrays, wireless options for retrofit, and the RCM certification needed in Australia and New Zealand.
Are external CTs included?
CT ratio depends on site current and is confirmed with the quotation. YADA manufactures the matching current transformers in-house.
