Módulo de batería LFP SOLAX 5,1 kWh, apilable, 90 % DoD, >6000 ciclos, IP65, mantas térmicas, supresión de incendios

The SOLAX 5.1 kWh LFP Battery Module is a high-performance, modular energy storage solution designed for residential and commercial solar systems. With a nominal energy capacity of 5.1 kWh and a usable capacity of 4.6 kWh, this lithium iron phosphate (LFP) battery offers exceptional safety and longevity. It features a 90% depth of discharge (DoD) and over 6000 cycles at 25°C, ensuring reliable performance for years. The stackable design allows up to 4 modules per system, providing scalable storage from 5.1 kWh to 20.4 kWh. Integrated heating mats enable operation in temperatures as low as -20°C, while the IP65 rating protects against dust and water ingress. An integrated fire extinguishing agent adds an extra layer of safety. The battery includes an intelligent BMS with CAN/RS485 communication, making it compatible with high-voltage inverter systems.

Advantages

This battery module offers several key benefits: long cycle life (>6000 cycles) reduces replacement costs; high DoD (90%) maximizes usable energy; wide operating temperature range (-20°C to 53°C) ensures functionality in harsh climates; IP65 protection allows outdoor installation; integrated heating mats enable cold-weather charging; and built-in fire suppression enhances safety. The modular, stackable design simplifies expansion, and the integrated BMS optimizes performance and protects against overcharge, overdischarge, overcurrent, and overtemperature.
