16kWh Low-Voltage Battery for Solar PV Systems

The 16kWh capacity makes this Felicity Solar battery suitable for customers who need more storage than a small 5kWh module, but do not require the larger 23.5kWh FLA48460TG2-EU model.

It is a practical choice for homes, villas, small businesses, workshops and backup-ready PV systems where daily self-consumption and battery storage are important.

For installers, the 51.2V low-voltage platform is also useful because it fits many residential hybrid inverter applications, subject to final inverter compatibility and local installation rules.

LiFePO4 Chemistry with High Cycle Life

The FLA48314-EU uses LiFePO4 battery chemistry, also known as lithium iron phosphate. This chemistry is widely used in solar energy storage because it is stable, long-lasting and suitable for frequent charging and discharging.

The datasheet lists a cycle life of ≥8000 cycles under stated test conditions. This gives the product strong positioning for long-term solar battery storage, especially for self-consumption systems that cycle every day.

For professional buyers, this is one of the key advantages over lower-grade battery technologies.

Smart BMS, Breaker and Fuse Protection

The Felicity Solar FLA48314-EU includes built-in smart BMS, breaker and fuse protection. This matters in professional energy storage installations because the battery system must be monitored and protected during charging, discharging and fault conditions.

The datasheet highlights multiple protection with built-in smart BMS, breaker and fuse. It also shows an external battery fuse design for easy replacement, which is useful for service work and long-term maintenance.

The user manual also includes BMS information, fault code guidance and protection details for voltage, current and temperature conditions.

CAN and RS485 Communication for Hybrid Inverter Integration

The FLA48314-EU supports RS485 and CAN communication. These protocols are commonly used for communication between solar batteries and compatible hybrid inverters.

This is important for installers because battery-inverter communication affects charging behaviour, monitoring, protection and system stability. Before installation, always check the latest Felicity Solar inverter compatibility list and the selected inverter’s communication settings.

The manual also shows communication port details and system connection diagrams for single battery and parallel battery configurations.

Scalable up to 15 Units in Parallel

The official datasheet confirms that the FLA48314-EU supports up to 15 units in parallel, giving a maximum scalable system capacity of 240kWh.

This gives installers and EPCs flexibility. One unit can serve a residential storage project, while multiple units can be used for larger home storage systems, commercial battery projects or more demanding backup applications.

The user manual also shows parallel connection diagrams and DIP switch settings for multi-battery systems.

Remote Monitoring with Built-in WiFi / Bluetooth

The datasheet lists built-in WiFi / Bluetooth for real-time monitoring as a feature of the FLA48314-EU.

For end users, monitoring helps track battery status and energy performance. For installers, it supports easier system checks, after-sales service and customer support.

The manual also includes FSolar App setup steps for network configuration and device management.

Floor-Mounted Battery Pack for Professional Installations

The FLA48314-EU is listed as a floor-mounted battery. The datasheet gives product dimensions of 435 × 880 × 247mm and product weight of 121.5kg.

This should be clearly shown on the product page because installers need to plan handling, placement, clearances and delivery before the product arrives on site.

The user manual also shows wall and floor placement guidance, including installation spacing and safe mounting instructions.
