xMarxon 5.12kWh 51.2V 100Ah LiFePO4 Rack Battery LR51.2-100 AMP
Model: LR51.2-100 AMP | Part number: LFELI-48100-E16 | SKU: 003309
The Marxon LR51.2-100 AMP (SKU: 003309) is a 5.12kWh rack-mounted lithium iron phosphate (LiFePO4) battery for 48V residential solar energy storage. It has a built-in BMS, a front LCD display and RS485, RS232 and CAN communication. Up to 15 units can be connected in parallel to build a larger battery bank.
Rated for more than 6000 cycles at 80% depth of discharge, with a design life of more than 15 years, it suits daily-cycling solar storage where long service life matters as much as capacity.

Product Overview
The rack format keeps installations tidy in a battery cabinet or rack, and the front LCD shows pack voltage, current, temperature and cell voltages without opening the inverter app. The front panel carries the DC breaker, two positive and two negative terminals, the communication ports, dry contacts and the address switch for parallel systems.
The built-in BMS protects against overcharge, over-discharge, overcurrent and temperature faults. Communication with the inverter is over RS485, RS232 or CAN, depending on the inverter make and model; the correct protocol must be selected during commissioning.
Marxon lists compatibility with mainstream inverter brands including PYLON, Sacolar, Growatt, Sofar, Voltronic, LUX, Schneider, Afore, Sinexcel, Sorotec, GoodWe, KSTAR, Srne, Must, Megarevo, Sol-Ark, INVT, Aiswei, TBB, SAKO, Solis, Victron, SMK, BlueSun. This list only indicates compatibility and does not mean the battery has been officially approved by each inverter manufacturer. Confirm compatibility, firmware and BMS protocol before installation.
