Constructed with a rugged IP54-rated housing, the meter complies with IEC 62053-22 (0.5S class accuracy) and supports bidirectional energy flow, allowing precise measurement of solar production, self-consumption, and grid import/export. The intuitive LCD displays phase-specific data, including voltage, current, active/reactive power, and power factor, while the Wi-Fi module enables seamless integration with PV monitoring platforms and smart home systems.
Bidirectional Energy Measurement: Accurately tracks energy flow in both directions (grid to load and PV to grid/load), essential for net metering applications. Supports real-time calculation of self-consumption ratio and feed-in tariff compensation.
MPPT Compatibility: Works with all major solar inverters to optimize energy harvest by monitoring inverter performance, voltage/current curves, and temperature coefficients. Generates alerts for mismatched strings or underperforming panels.
Three-phase Precision: Monitors each phase independently, detecting unbalanced loads, harmonic distortions, and power factor issues that could reduce system efficiency. Provides detailed reports for PV system diagnostics and maintenance.
Smart Connectivity: Connects to 2.4GHz Wi-Fi networks for remote access via the SolarGuard app, which offers live data dashboards, historical trend analysis, and OTA (Over-The-Air) firmware updates. Integrates with 第三方 platforms like SolarEdge and SMA via Modbus RTU/ASCII protocols.
Flexible Installation: Features a DIN-rail mountable design and supports both direct connection (up to 100A) and CT-based installation (for loads >100A), adapting to small residential arrays and large commercial PV plants alike.
Residential Solar Systems: Installed in homes with rooftop PV panels to monitor energy generation, track savings from net metering, and optimize self-consumption by scheduling high-energy tasks during peak solar production.
Commercial Solar Farms: Used in large-scale PV installations to monitor performance across multiple inverters and phases, ensuring maximum energy yield and compliance with grid regulations. Generates detailed reports for carbon credit calculations.
Hybrid Energy Systems: Integrates with battery storage and diesel generators in off-grid setups, balancing energy supply between PV, batteries, and backup sources while preventing overloading during low-light conditions.
Utility Grid Monitoring: Deployed by power companies to verify net metering data, detect grid faults, and optimize distribution in areas with high PV penetration, improving overall grid stability.
Q: What is the difference between this meter and a standard three-phase meter?
A: This meter is optimized for PV systems, supporting bidirectional flow, MPPT tracking, and solar-specific metrics like self-consumption rate. Standard meters lack these PV-specific features.
Q: Do I need a separate CT for each phase?
A: Yes, for loads exceeding 100A, three current transformers (one per phase) are required. The meter includes terminals for CT connections, simplifying installation in high-current setups.
Q: Can this meter be used without a solar system?
A: Yes, it functions as a standard three-phase smart meter for energy consumption monitoring, though the PV-specific features like MPPT tracking will remain unused.
Q: How does the meter handle daylight saving time changes?
A: The built-in real-time clock auto-syncs with network time protocols (NTP) via Wi-Fi, ensuring accurate timestamping for energy reports without manual adjustments.
Q: What is the warranty for this meter?
A: It comes with a 5-year manufacturer warranty, covering defects in materials and workmanship. Annual calibration is recommended for maintaining 0.5S class accuracy.
