A 20kWh Residential<\/strong> Energy Storage<\/a> Upgrade in Spain<\/h3>\n\n\n\n

We recently received installation photos from a customer in Spain. The customer already owned a Deye inverter and wanted to increase the storage capacity of the existing home solar system. To meet this requirement, LVFU Energy supplied two 10 kWh wall-mounted batteries, creating a total 20kWh residential energy storage system<\/strong>.<\/p>\n\n\n\n

Two 10 kWh Wall-Mounted Batteries<\/a> for Space-Saving Installation<\/h3>\n\n\n\n

The project uses two 10 kWh wall-mounted batteries, which provide a combined storage capacity of 20 kWh. The customer mounted both batteries on the wall alongside the Deye inverter. As a result, the installation creates a compact and organized equipment layout while making efficient use of the available wall space.<\/p>\n\n\n\n

In addition, the wall-mounted design reduces the system\u2019s use of floor space. Therefore, this 20kWh home energy storage system<\/strong> can suit home utility rooms, garages, and other areas with limited installation space.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Integration with the Customer\u2019s Existing Deye Inverter<\/h3>\n\n\n\n

During the project, the installation team connected the two LVFU 10 kWh batteries with the customer\u2019s existing Deye inverter. The customer therefore upgraded the solar energy system without replacing the original inverter or significantly changing the existing layout.<\/p>\n\n\n\n

This approach allows homeowners to add battery storage while continuing to use suitable existing equipment. However, installers should always confirm the exact inverter model, communication protocol, voltage range, power specifications, and battery configuration requirements before starting a new project.<\/p>\n\n\n\n

<\/p>\n\n\n\n

A Flexible 20kWh Residential Energy Storage Configuration<\/h3>\n\n\n\n

The two batteries use a modular configuration that matches the customer\u2019s current home energy storage needs. At the same time, the modular design provides a flexible foundation for future expansion, subject to the inverter specifications and the battery system\u2019s parallel-connection requirements.<\/p>\n\n\n\n

For homeowners who want to improve solar self-consumption or increase their available storage capacity, a 20kWh residential energy storage system<\/strong> can provide a practical upgrade option. The final battery capacity should always reflect the household\u2019s energy consumption, solar generation, backup requirements, and available installation space.<\/p>\n\n\n\n

This Spain 20kWh residential energy storage case highlights the advantages of LVFU wall-mounted batteries in space utilization, system integration, and home solar upgrades. By adding two 10 kWh batteries, the customer increased the system\u2019s storage capacity while keeping the existing Deye inverter.<\/p>\n\n\n\n

If you are looking for a 20kWh residential energy storage solution compatible with a Deye inverter, contact LVFU Energy with your inverter model, system parameters, installation environment, and target battery capacity. Our team can help you evaluate a suitable home energy storage configuration for your project.<\/p>\n\n\n\n
