At the Warsaw Solar Energy Expo in Poland, Felicitysolar’s residential LiFePO4 battery FLB48314TG1 was awarded the PTAK Excellence Award in the category of “MAGAZYNOWANIE ENERGII” (Energy Storage).
This recognition highlights the system’s strong performance, safety design, and suitability for the evolving needs of European and North American households seeking reliable solar energy solutions.
Designed specifically for residential applications, the FLB48314TG1 supports homeowners in building stable, flexible, and future-ready solar energy battery storage systems—whether for grid-connected, hybrid, or off-grid scenarios.
Safety Designed for Everyday Residential Use
Safety remains a top priority for residential energy storage, especially for long-term installation in homes. The FLB48314TG1 is engineered with multiple layers of protection to ensure safe and reliable operation over its entire service life.
The battery series features an intelligent built-in BMS, circuit breaker, and fuse, forming a comprehensive protection architecture against common electrical risks. With an IP65 protection rating, the battery series is well suited for outdoor installation and can withstand harsh environmental conditions. In addition, an integrated aerosol fire suppression system further enhances fire safety, offering homeowners greater peace of mind.
Reliable Performance, Even in Cold Climates
To meet the demands of users in colder regions of Europe and North America, this battery is equipped with an optional heating module (FLB48314TG1-H model). This function allows the battery to automatically restore itself to an optimal operating temperature, ensuring stable performance even in low-temperature environments.
Advanced CCS welding technology is applied to reduce internal resistance, improving overall efficiency and system stability. These design choices make the FLB48314TG1 a dependable solar energy battery storage for residential systems paired with a hybrid inverter or an off grid inverter.
Smart Energy Management for Modern Homes
The FLB48314TG1 integrates smart monitoring capabilities through built-in WiFi and Bluetooth, allowing users to remotely access real-time battery data. This intelligent connectivity helps homeowners better understand their energy usage and system status, supporting more efficient energy management within complete solar energy solutions.
Long Service Life and Flexible Expansion
Built for long-term value, the FLB48314TG1 delivers up to 8,000 charge-discharge cycles, making it a solid investment for residential energy storage over many years. The battery also supports flexible capacity expansion, with up to 32 units connected in parallel, reaching a total capacity of 512 kWh. This scalability allows homeowners to expand their solar energy battery storage system as energy needs grow, without replacing existing equipment.
A User-Centered Approach to Residential Energy Storage
The PTAK Excellence Award reflects not only the technical strength of the FLB48314TG1, but also Felicitysolar’s continued focus on user-oriented design. By combining safety, reliability, intelligent control, and scalability, the FLB48314TG1 supports households in building stable and efficient energy systems with hybrid inverters or off grid inverters.
Felicitysolar remains committed to developing residential energy storage products that respond to real user needs, contributing to more accessible, reliable, and sustainable solar energy solutions for homes and communities worldwide.
