45kWh Residential Battery Storage Installation in Portugal
This residential energy storage project in Portugal uses three 15kWh rack-mounted LiFePO4 battery modules to provide 45kWh of nominal storage capacity. The system is integrated with the home’s solar and electrical equipment to increase solar self-consumption, provide backup energy and improve household power management.
- Location: Portugal
- Nominal Capacity: 45kWh
- Battery Configuration: 3 × 15kWh
- Installation: Dedicated Indoor Utility Room
A 45kWh Battery System for a Solar-Powered Home
The homeowner required more storage capacity than a standard residential battery could provide. The system needed to store surplus solar electricity, support household loads after sunset and maintain backup capacity for selected circuits during power interruptions.
Avepower supplied a modular 45kWh battery bank consisting of three rack-mounted LiFePO4 battery modules. The batteries were installed in a dedicated indoor electrical area together with the inverter, system controller, protection equipment and power distribution components.
The modular arrangement provides substantial residential storage capacity while keeping the equipment accessible for installation, inspection and future servicing.
Integrated with the Home’s Power Conversion and Control Equipment
The installation combines the battery bank with compatible inverter, monitoring, electrical protection and distribution equipment.
The system layout supports coordinated control of:
- Solar PV Generation
- Battery Charging
- Battery Discharging
- Household Loads
- Grid Connection
- Backup Circuits
- System Alarms
Battery and inverter compatibility should be confirmed before installation, including voltage range, current limits, communication protocol and operating parameters.
Battery Monitoring and Protection at Module Level
Each battery module includes an intelligent battery management system that monitors operating conditions and helps keep the complete battery bank within approved limits.
- Cell Voltage Monitoring
- Temperature Monitoring
- Current Monitoring
- SOC Calculation
- Cell Balancing
- Alarm Reporting
- Charge Protection
- Discharge Protection
The BMS can communicate operating information to compatible system equipment, helping the inverter adjust charging and discharging according to battery status.
A Practical High-Capacity Storage Solution for Residential Use
The completed installation provides the homeowner with a structured 45kWh battery platform for solar energy storage and household backup.
By using three independent rack-mounted modules, the system combines high storage capacity with manageable installation and service requirements. The electrical equipment is organized in one dedicated area, giving installers clear access to the batteries, inverter, control system and protection components.
The project demonstrates how a modular commercial-style battery architecture can be adapted to higher-consumption residential applications.
