Performance and Integration
The HomeWizard Plug-In battery seamlessly integrates with the home's existing energy system, responding quickly to changes in demand. During testing, it efficiently managed power fluctuations, providing a stable energy supply. Its ability to both draw from and return power to the grid is a key advantage. The software is intuitive and user-friendly, offering a clear overview of battery performance and energy usage patterns.
The battery's performance is impressive, consistently delivering on its promises. In my experience, the integration with the P1 meter is excellent, ensuring smooth operation and accurate data collection. The system's quick response to demand changes means consistent and reliable power.
One minor issue was encountered: a bootloop occurred in colder temperatures (around 10 degrees Celsius or lower). However, a recent software update seems to have resolved this problem entirely, greatly improving the battery's reliability and usability in various climates.
Data Analysis and Usage Patterns
Detailed graphs illustrate daily power consumption, solar generation, and battery usage. These visuals provide a comprehensive understanding of how the battery interacts with the home's energy system. A significant amount of energy was returned to the grid (8.3 kWh on one day), showcasing the battery's efficiency in optimizing energy usage.
The graphs clearly show the correlation between solar generation, energy consumption, and battery charging/discharging cycles. The battery efficiently stores excess solar energy and then uses it to reduce grid dependency during peak demand periods. The visualization highlights the battery's intelligent power management, ensuring optimal efficiency.
Daily data reveals the battery's effectiveness in peak shaving and grid support. The battery successfully buffers against power surges, maintaining a stable energy supply within the home. Detailed analysis also reveals the battery's roundtrip efficiency and its overall impact on reducing reliance on the electricity grid.
Capacity and Expansion
The 2.7 kWh battery capacity proved insufficient for evening/nighttime usage. The data suggests that adding one or two more batteries would significantly improve the system's ability to meet the home's energy demands. This would nearly eliminate the need to draw power from the grid during off-peak hours.
Based on the data, upgrading to a larger battery capacity is recommended for improved performance. The current capacity is sufficient for peak shaving but falls short of providing full energy independence overnight. Adding additional batteries would enhance the system's overall capabilities.
The reviewer's intention is to expand the setup to include three batteries in total, likely to be distributed across different phases for improved energy distribution. While not strictly necessary, it improves power management and balances the load across the system
Feature Request and Conclusion
A key feature request is the addition of delayed charging. Currently, the battery charges immediately when surplus solar energy is available, which could be less efficient depending on electricity pricing. Delayed charging could optimize energy usage and maximize returns under a dynamic electricity pricing plan.
The delayed charging feature would allow for smarter energy management. By delaying the charging process until off-peak hours, the user could potentially reduce electricity costs and increase their overall energy savings. This improvement would greatly enhance the battery's ability to adapt to dynamic electricity tariffs.
Overall, the HomeWizard Plug-In Battery is a highly efficient and well-integrated system. Despite the initial cold-weather issue (now resolved), the battery's performance and ease of use are impressive. Expansion for increased capacity is recommended for homes with higher energy demands. The addition of delayed charging would further enhance its functionality.
