Project Background

Located in Halle, Germany, this detached house was owned by the Schmidt family, who have long been committed to energy sustainability and wanted to reduce their reliance on the traditional power grid. With rising electricity prices in Germany (reaching up to €0.45/kWh during peak hours) and government incentives for self-consumption of renewable energy, they decided to install a solar photovoltaic (PV) system on their roof and configure a Dawnice residential energy storage system to achieve greater energy self-sufficiency and economic efficiency.

Project Description

The system features a modular design, installed in the home storage area, saving space and simplifying maintenance. The energy storage system uses lithium iron phosphate (LFP) cells, ideally chosen for their high safety and long cycle life. It is equipped with an intelligent battery management system that supports automatic charging during off-peak hours or peak PV generation, and automatic discharging during peak hours or at night, optimizing household electricity costs.

User Feedback

"After installing the Dawnice energy storage system, our electricity bills have significantly decreased, especially in winter, when the system effectively ensures heating and lighting in our home. During the recent power outage due to regional grid maintenance, our family was one of the few unaffected households in the neighborhood, and our children's studies and daily life were completely undisturbed. This system not only brings economic benefits but also provides us with peace of mind." — Mr. Schmidt, homeowner

Project Outcomes

Economic Benefits: Monthly household electricity bills reduced by approximately 60%

Energy Efficiency: Solar energy self-consumption rate increased to 85%, significantly reducing reliance on the grid.

Power Supply Reliability: Seamless switching ensures continuous power supply to critical loads, improving the stability of household electricity usage.

Environmental Contribution: Reduces carbon emissions by approximately 1.5 tons annually, helping families achieve a greener lifestyle.
