Reliable LiFePO4 Energy Storage for Homes and Businesses

As Europe moves toward a more renewable and flexible energy system, battery energy storage is becoming an increasingly important part of modern solar energy.

Solar PV generates electricity mainly during the day, while household and business energy demand often continues into the evening. Battery storage helps bridge this gap by storing surplus solar energy and making it available when needed.

Wattnova is developing LiFePO4 energy storage solutions for the European market, with capacities from 7kWh to 35kWh for residential and commercial applications.

Why Energy Storage Matters in Europe

The growing adoption of solar PV, electric vehicles, heat pumps and other electrical loads is changing how homes and businesses use energy.

Battery storage allows surplus renewable energy to be stored and used later, helping users:

• -Increase solar self-consumption
• -Store surplus renewable energy
• -Reduce reliance on grid electricity
• -Improve energy independence
• -Provide backup power
• -Better manage changing energy demand

As renewable energy adoption continues to grow, energy storage provides an important link between energy generation and consumption.

Wattnova Energy Storage Range

Wattnova offers four energy storage capacities for different residential and commercial requirements:

Capacity	Typical Application
7kWh	Compact residential storage
10kWh	Residential applications
15kWh	Larger homes and small commercial
35kWh	Commercial and higher-demand applications

The right capacity depends on electricity consumption, solar PV capacity, backup requirements, installation space and future energy needs.

Key Features

LiFePO4 Battery Technology

Wattnova energy storage solutions use Lithiumeisenphosphat (LiFePO4) technology, providing a reliable foundation for long-term stationary energy storage.

Long Cycle Life

Selected systems are designed for up to 8,000 Zyklen, depending on the specific model and operating conditions.

High Usable Capacity

Selected configurations support a high depth of discharge, helping users make effective use of the installed battery capacity.

IP66 Protection

IP66-rated enclosures provide protection against dust and powerful water jets, supporting indoor and suitable outdoor installation environments.

Intelligent Communication

CAN communication enables integration with compatible inverters and energy management systems.

Natural Cooling

Natural convection cooling reduces reliance on additional mechanical cooling components.

Energiespeicher für Privathaushalte

Wattnova batteries can be integrated with solar PV systems to help households make better use of renewable electricity.

A typical system can be configured as:

Solar PV → Hybrid Inverter → Wattnova Battery → Home Loads

Surplus solar energy generated during the day can be stored and used when solar production falls, such as in the evening.

Depending on the system configuration, residential storage can support:

• -Higher solar self-consumption
• -Backup power
• -Greater energy independence
• -More flexible household energy management

Der 7kWh and 10kWh configurations are suitable for many residential applications, while 15kWh provides additional storage for larger homes and higher energy consumption.

---

Commercial Energy Storage

Commercial and agricultural sites often have higher or more variable energy demand than residential properties.

Der 15kWh and 35kWh configurations can be used for selected applications such as:

• -Farms and agricultural facilities
• -Workshops
• -Offices
• -Warehouses
• -Commercial solar PV systems
• -Backup power

By storing surplus solar generation, battery storage can help businesses make better use of on-site renewable energy while adding flexibility to their energy systems.

Designed for European Applications

Energy storage requirements vary between European markets due to differences in electrical systems, installation practices and local regulations.

The final system should therefore be selected according to:

• -Local electrical requirements
• -Inverter compatibility
• -Solar PV capacity
• -Load profile
• -Installation environment
• -Applicable regulations

Wattnova product documentation includes compliance-related references such as:

• -IEC 62619
• -IEC/EN 62040
• -IEC/EN 62477
• -U38.3
• -EU-Batterieverordnung 2023/1542

Certification scope and model coverage should be confirmed for the final product and specific European market before deployment.

Choosing the Right Capacity

There is no single battery size for every project. The appropriate capacity depends on the property’s electricity consumption, solar generation, backup requirements and future energy needs.

As a general guide:

7kWh — Compact residential storage
10kWh — Residential applications
15kWh — Larger homes and small commercial
35kWh — Commercial and higher-demand applications

Professional system design should consider the complete energy profile, including electricity consumption, solar PV capacity, inverter configuration and backup requirements.
