New Trends and Market Potential of Balcony Energy Storage

As renewable energy becomes more widespread and the demand for home energy storage increases, balcony photovoltaic + storage systems are emerging as a new trend in household energy management. Measuring the generation, consumption, and grid interaction data of these storage systems is essential for optimizing energy efficiency. Ankorey’s metering instruments, known for their high precision, multifunctionality, and intelligence, provide reliable measurement solutions for home balcony storage.

Importance of Balcony Energy Storage and Metering

1. Enhancing Energy Self-sufficiency: Balcony photovoltaic storage systems can convert solar energy into electricity and store it, reducing dependence on the grid. By measuring energy production and consumption in real-time, households can adjust their usage patterns, maximizing self-generated energy and lowering electricity costs.
2. Supporting Time-of-Use Pricing Strategies: Under a time-of-use pricing model, storage systems can charge during off-peak hours when electricity prices are low and discharge during peak hours. Ankorey’s metering instruments support four pricing tiers (peak, flat, and off-peak) and provide 12 months of historical energy statistics, helping users flexibly plan their charging and discharging strategies, potentially saving over 20% on annual electricity costs.
3. Ensuring Electrical Safety: Storage systems involve complex processes such as battery management and charge/discharge control, requiring real-time monitoring of voltage, current, and temperature. The ADW300 from Ankorey features alarms for overvoltage, overcurrent, and excessive temperature, which can promptly trigger protective measures to prevent equipment damage or fire risks.

Design of Household Balcony Energy Storage Metering Solutions

1. System Architecture: Storage devices include balcony photovoltaic panels and lithium battery storage systems. The metering node, ADW300, is placed at the output of the storage system to monitor charge/discharge quantities and grid interaction data. Data is synchronized to a mobile app or cloud platform via 4G/WiFi for remote management.
2. Implementation Key Points:
   • Current Transformer Selection: Choose compatible open-type current transformers (e.g., AKH-0.66 series) based on the current range to ensure sampling accuracy and avoid interference.
   • Rate Configuration: Set peak and off-peak periods according to local electricity pricing policies, allowing the meter to automatically switch billing modes.
   • Safety Protection: Activate alarms for overload, temperature, and residual current, and link with a DO module for automatic power-off protection.

Core Advantages of Ankorey’s ADW300 Metering Instrument

1. High Precision and Multi-Parameter Measurement: The energy meter supports both forward and reverse active/reactive energy measurements, with precision of 0.5S for active energy and Class 2 for reactive energy, ensuring data reliability. It also provides real-time monitoring of voltage, current, power factor, frequency, and supports analysis of 31 harmonics to assess power quality.
2. Flexible Installation and Wireless Communication: The compact design of the instrument allows for DIN rail installation, fitting within the constraints of household distribution boxes. It supports wireless transmission via built-in 4G, WiFi, or LoRa modules, eliminating the need for complex wiring and enabling direct data uploads to the cloud or mobile app for convenient remote monitoring. The non-invasive open-type current transformer can be installed without modifying existing circuits, making it suitable for home deployment.
3. Intelligent Management and Data Analysis: The meter supports two rate tables, four time zones, and 14 daily time slots, storing 12 months of historical data to aid in optimizing usage patterns. Through Ankorey’s energy management cloud platform, users can generate energy reports, analyze efficiency trends, and integrate with smart home devices for automated control.

Conclusion

Household balcony energy storage represents not only a shift in energy consumption but also embodies the concept of a smart lifestyle. Ankorey’s electric instruments facilitate efficient, safe, and economical energy systems through precise metering and intelligent management. As technology continues to evolve, household energy management will become increasingly refined, undoubtedly serving as the “energy steward” in this process.
