1. Real-Time Monitoring & Data Acquisition in PV Systems

Key Functions:

• Sensor Integration: ARMxy collects data from:

  • PV inverters (power output, voltage, current)

  • Irradiance & temperature sensors (panel efficiency tracking)

  • Battery management systems (BMS) (SOC, SOH, temperature)

• Protocol Support:

  • Modbus TCP/RTU (for inverters & meters)

  • IEC 61850 (grid communication)

  • DNP3 & MQTT (SCADA & cloud integration)

• Edge Data Processing:

  • Reduces cloud dependency by preprocessing data locally.

  • Implements MPPT (Maximum Power Point Tracking) algorithms for efficiency optimization.

Technical Advantage:

ARMxy’s low-latency processing ensures rapid response to fluctuations in solar generation, improving energy harvest efficiency by 3-5%.

2. Battery Storage Management & Optimization

Key Applications:

• State-of-Charge (SOC) Estimation:

  • ARMxy runs Kalman filtering or machine learning models to improve SOC accuracy.

  • Prevents overcharging/deep discharging, extending battery lifespan.

• Dynamic Load Balancing:

  • Adjusts charge/discharge cycles based on grid demand and solar generation.

  • Supports peak shaving to reduce electricity costs.

• Thermal Management:

  • Monitors battery temperature and triggers cooling systems if overheating is detected.

3. Grid Integration & Demand Response

Smart Grid Interaction:

• Bidirectional Power Flow Control:

  • ARMxy manages inverter setpoints to feed excess solar power into the grid.

  • Supports V2G (Vehicle-to-Grid) if EVs are integrated.

• Frequency Regulation:

  • Responds to grid frequency dips by injecting stored energy within milliseconds.

• Demand-Side Management:

  • Uses forecasting algorithms to optimize battery dispatch during peak pricing.

Compliance & Safety:

• IEC 61727, IEEE 1547 (grid interconnection standards)

• UL 1973 (battery safety certification)

4. Edge AI for Predictive Maintenance & Fault Detection

AI-Driven Diagnostics:

• Anomaly Detection:

  • Uses LSTM neural networks to predict inverter failures.

  • Detects potential hot spots in PV panels via thermal imaging data.

• Predictive Maintenance:

  • Estimates remaining useful life (RUL) of batteries using degradation models.

  • Reduces downtime by 30% compared to reactive maintenance.

Example: Fault Detection in a Solar Farm

1. Data Input: Current/voltage fluctuations, temperature spikes.

2. AI Model: Identifies potential arc faults or PID (Potential Induced Degradation).

3. Action: Triggers alarms or isolates faulty panels automatically.
