New Trends and Market Potential of Balcony Energy Storage

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

1. Importance of Balcony Energy Storage and Metering

• Enhancing Energy Self-Sufficiency: Balcony photovoltaic storage systems convert solar energy into electrical energy and store it, reducing reliance on the grid. By monitoring energy generation and consumption in real-time, households can adjust their energy usage periods, maximize the use of self-generated power, and lower electricity costs.
• Supporting Time-of-Use Pricing Strategies: Under a time-of-use pricing model, energy 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 rates (peak, flat, and off-peak) with 12 months of historical energy statistics, helping users flexibly plan their charging and discharging strategies, potentially saving over 20% on annual electricity bills.
• Ensuring Electricity Safety: Energy storage systems involve complex processes such as battery management and charge/discharge control, necessitating real-time monitoring of parameters like voltage, current, and temperature. The Ankorey ADW300 provides alarm functions for over-voltage, over-current, and high temperature, triggering protective measures to prevent equipment damage or fire risks.

2. Design of Household Balcony Energy Storage Metering Solutions

1. System Architecture: Energy storage equipment consists of balcony photovoltaic panels and lithium battery storage systems. The metering node is the ADW300, deployed at the output of the storage system to monitor charge/discharge amounts 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 to DO modules for automatic power cut-off protection.

3. Core Advantages of Ankorey ADW300 Metering Instruments

1. High Precision and Multi-Parameter Measurement: The energy metering supports both forward and reverse active/reactive energy, with accuracy levels of 0.5S for active and Class 2 for reactive energy, ensuring data reliability. It also enables real-time monitoring of voltage, current, power factor, frequency, and supports 31 harmonics analysis to assess power quality.
2. Flexible Installation and Wireless Communication: The compact design allows for rail mounting, fitting into limited space in home distribution boxes. Wireless transmission can be achieved with built-in 4G, WiFi, or LoRa communication modules, eliminating complex wiring and allowing data to be uploaded directly to the cloud or mobile app for convenient remote monitoring. The open-type current transformer design allows for non-invasive installation, suitable for household deployment.
3. Intelligent Management and Data Analysis: Supports two sets of time-based billing, four time zones, and 14 daily time slots, storing 12 months of historical data to optimize energy usage patterns. Through Ankorey’s energy management cloud platform, users can generate electricity reports, analyze energy efficiency trends, and integrate with smart home devices for automated control.

4. Conclusion

Household balcony energy storage is not only a reflection of the energy revolution but also embodies the concept of a smart lifestyle. Ankorey’s electrical instruments provide users with efficient, safe, and economical energy systems through metering and intelligent management. In the future, as technology evolves, household energy management will become increasingly refined, undoubtedly positioning itself as a “energy steward” in this transition.
