Project Background

The Schmidt family, located in the suburbs of Munich, Germany, decided to install a home energy storage system to cope with rising electricity prices (reaching €0.48/kWh during peak hours) and increasingly frequent power outages caused by extreme weather. The family already had a rooftop solar system, but only 35% of their electricity was used for their own needs, with a significant amount of surplus electricity fed back to the grid at low prices, indicating a need to improve energy efficiency.

Project Introduction

This project utilizes the Dawnice 15kWh residential energy storage system, equipped with high-performance lithium iron phosphate batteries with a cycle life exceeding 8000 cycles. The system uses an intelligent energy management system to intelligently allocate solar power generation, grid power supply, and household electricity consumption. The entire system is wall-mounted, installed on the garage wall, seamlessly integrating into the home environment.

System Operating Features

Peak-Valley Arbitrage Mode: Charging occurs during off-peak hours (€0.22/kWh) and discharging during peak hours, while also allowing for self-sufficiency in power generation through solar panels.

Emergency Backup Mode: Switches to a backup mode within 0.02 seconds in the event of a grid outage, ensuring continuous power supply to critical equipment.

User Feedback

"After installing the Dawnice energy storage system, our photovoltaic self-consumption rate increased from 35% to 85%, and our monthly electricity bill decreased by approximately 65%. Last week, during a 6-hour power outage due to community grid maintenance, our household appliances were still usable, and our children's studies were completely unaffected. This system not only brought economic benefits but also gave our whole family peace of mind."
