Description

LiFePO4 storage battery in rack format, designed for residential and commercial low voltage photovoltaic systems. With a nominal voltage of 51.2V and a capacity of 100Ah, it stores up to 5.12kWh of energy, improving self-consumption and cutting energy bills.

The product is CEI 0-21 certified and therefore compliant with Italian standards for grid-connected systems. It is ready to use and requires no particular initial configuration: it is supplied with brackets, connection cables and installation manual.

Safety and reliability

The lithium iron phosphate (LFP) chemistry ensures high thermal stability and operational safety, with more than 6,000 cycles of charge/discharge and a 10-year warranty. The integrated BMS manages protection against overvoltage, undervoltage, overcurrent, short circuit and temperature, balancing the cells and maintaining consistent performance over time.

The maximum continuous current is 100A in charge and discharge, with peak power up to 5.12kW. Operation is designed for 0 to 60 °C in charge and -20 to 60 °C in discharge; the battery is maintenance-free.

Installation and expandability

The rack format allows installation in a cabinet or on the wall. Up to 16 units can be connected in parallel per inverter, with no need for an external HV Box: the system therefore remains scalable over time, from a single module up to more than 80kWh. A dedicated rack cabinet is recommended for configurations with three or more batteries.

Before ordering, always check the inverter's compatibility with low voltage batteries and the maximum capacity it supports.
