Narrative

Technical Innovation & Quality Heritage

YTL’s Solar PV Meters are the essential measurement heart of modern "Prosumer" energy systems. As more buildings transition to generating their own power, the need for high-precision bi-directional metering becomes paramount. Our specialized PV meters provide separate registers for energy imported from the grid and green energy exported back, facilitating seamless participation in Net-Metering and Feed-in Tariff (FiT) programs. As a leading manufacturer, Zhejiang Yongtailong has integrated 4-quadrant measurement into these devices, ensuring that active and reactive power are tracked with revenue-grade accuracy. With optional wireless connectivity like Wi-Fi or LoRaWAN, these meters allow homeowners and commercial operators to view their solar yield and self-consumption ratios in real-time, driving smarter energy behaviors and maximizing the financial benefits of renewable investments.

Product Application

  • Residential Net-Metering
  • Commercial Solar Farms
  • Hybrid Storage Integration

Residential Net-Metering

Designed for home rooftop solar installations. These meters provide a legal, utility-ready record of the energy you feed back into the grid. This transparency ensures you are accurately credited on your utility bill, helping to shorten the payback period of your solar investment while allowing you to monitor your home's total self-sufficiency through our mobile app.

Commercial Solar Farms

Provides utility-grade measurement for industrial solar arrays. The high-precision 4-quadrant tracking ensures that reactive power generated by inverters is monitored, which is often a requirement for grid stability agreements. The robust RS485 or wireless communication allows for easy integration into a centralized SCADA system for multi-site performance tracking.

Hybrid Storage Integration

Ideal for systems that combine solar panels with battery storage. The meter acts as the primary data source for the hybrid inverter, telling it exactly when to charge the batteries from excess solar and when to discharge them to avoid drawing expensive power from the grid, optimizing your total energy cost automatically.

Product Advantages

Net-Metering Ready

Features dedicated registers for total import, total export, and net energy, fully complying with global utility requirements for grid-tied solar systems.

High Sampling Frequency

Utilizes advanced digital signal processing to capture rapid changes in solar output due to cloud cover, ensuring that every watt of generated green energy is accounted for.

Low Self-Consumption

The meter's internal circuitry is designed for ultra-low power draw, ensuring that the measurement process itself doesn't significantly impact the overall efficiency of your solar system.

Frequently Asked Questions

  • Q: Does this meter show how much money I've saved?

    A: While the meter shows kWh, our paired mobile app can be configured with your local electricity rates to show real-time financial savings and earnings.

  • Q: Is it compatible with my specific inverter brand?

    A: Our meters support standard Modbus protocols used by most major inverter brands, and we also offer SunSpec-compliant models for easy plug-and-play integration.

  • Q: Can I install this meter outdoors near the panels?

    A: The meter has an IP51 or IP54 rating. For outdoor use, it should be installed inside a standard protective meter box to guard against direct UV and heavy rain.

  • Q: Does it measure both active and reactive power?

    A: Yes, it provides full 4-quadrant measurement, which includes active, reactive, and apparent power in both directions—essential for modern grid requirements.

  • Q: Do I need a technician to read the data?

    A: No, the data can be viewed directly on the backlit LCD screen or remotely via your smartphone or computer if you choose a model with Wi-Fi or Cellular connectivity.
