Complet Batterie Au Lithium 50kwh Stromspeicher 100Kw 48Kwh 100Kwh All in One 48 50 100 300 Kw Kwh Strom Speicher Solar Systems

The 50KWH Battery Pack features a nominal voltage of 51.2V with a rated energy capacity of approximately 50KWH. It utilizes Grade A LiFePO4 prismatic cells (314Ah each), configured in a 16S3P arrangement (48 cells total). The system supports up to 300A continuous discharge current, operates within -20~60 degrees C, and delivers 6,000-8,000 charge cycles at 80% DOD. The built-in smart BMS provides overcharge, over-discharge, short circuit, and temperature protection with CAN/RS485 Communication.

The QSO 50KWH battery pack uses high-quality LiFePO4 square cells, each with a capacity of 314Ah, sourced from a leading Chinese manufacturer. Each cell is encapsulated in an aluminum shell and has laser-welded terminals, with a nominal voltage of 3.2V. The 16S3P configuration consists of 48 cells, with strict cell matching: the total capacity deviation is within ±1%, and the internal resistance deviation is within ±3 milli-ohms.

50KWH integrated intelligent BMS, equipped with 2A active cell balancing to maintain the voltage consistency of all 48 cells. Protection functions: overcharge cutoff for each cell at 3.65V ± 0.05V, overdischarge cutoff for each cell at 2.5V ± 0.05V, overcurrent protection, short circuit response less than 100 microseconds, temperature protection, cell voltage imbalance protection. Communication: CAN bus, RS485, optional RS232. Compatible with mainstream brands such as, Growatt, Victron, SMA

Yes, QSO 50KWH has been optimized for off-grid solar energy storage. The 51.2V nominal voltage is compatible with most 48V off-grid inverters. A single unit can provide 2-3 days of backup power for a typical household with a daily consumption of 15-20KWH, supporting deep cycling up to 90% DOD. The self-discharge rate is less than 3% per month. Up to 15 units can be connected in parallel, with a total capacity of 750KWH.

The QSO 50KWH supports major inverter brands via CAN/RS485:Growatt, Victron Energy, SMA, Goodwe, Solis, Luxpower, SRNE, Voltronic, Sofar, Sungrow, Schneider Electric, SolaX, Megarevo, MUST, Phocos, INVT, and KEHUA. Closed-loop CAN communication provides optimal performance with accurate SOC and charge profiles. The battery can also operate in open-loop voltage-controlled mode with any 48V inverter. Before purchase, verify: your inverter supports 48V/51.2V nominal.

Up to 15 QSO 50KWH units can be connected in parallel, with a total capacity of 750KWH. The BMS system communicates via the CAN bus in a master-slave architecture, with the master coordinating the SOC balance and charging/discharging behaviors of all groups. Requirements: All units must have the same voltage and configuration; the initial SOC difference before parallel connection should be less than 10%; a suitable DC busbar or combiner box is required, along with appropriate fuses;

It supports 16 parallel connections, offers free scheme design and capacity planning suggestions to help customers assess their own needs (average daily electricity consumption, maximum load power, electricity price policies), and builds your home photovoltaic renewable energy system. Modular design supports parallel expansion + compatibility with mainstream photovoltaic systems + intelligent EMS automatically optimizes power usage strategies,(Self-consumption / Peak-valley arbitrage).
