QSO New 2027 Eu Stock 32Kwh 51.2V Mb56 Battery Box Caja Batteriebox 16S V19 Jk-pb2a16s30p 668Ah 628Ah 48V Lifepo4 Diy Kit Case

The QSO MB56 32kWh pack is factory-tested and validated for compatibility with more than 20 leading inverter brands, including Victron Energy, Deye, Growatt, Sol-Ark, EG4, Luxpower, GoodWe, SMA, Schneider, and MPP Solar. The integrated BMS supports dual communication buses: CAN bus for inverter control and RS485 for monitoring. Communication protocols are pre-loaded for the most common brands, ensuring plug-and-play recognition.

The pack features a 200A rated smart BMS with active cell balancing (2A balancing current) combined with passive balancing during float phase, maintaining cell deviation within ±25mV. Protection functions include: over-voltage (per-cell and pack), under-voltage, over-current (discharge and charge), short-circuit protection with automatic recovery, high and low temperature cutoff, and insulation resistance monitoring.

The 16S configuration is the industry standard topology for 48V LiFePO4 systems.Since 16 batteries at 3.2V each equal 51.2V,it precisely matches the nominal DC bus voltage of almost all mainstream hybrid and off-grid inverters.Compared to the 8S (25.6V) or 32S (102.4V) configurations,16S achieves the best balance in terms of cable current-carrying capacity,battery management system (BMS) complexity,and compatibility with existing 48V inverter ecosystems from brands such as Victron, Deye, Growat.

Yes.The 32kWh pack is designed for parallel expansion.Up to 4units can be connected in parallel to form a single 128.6kWh system with unified BMS communication and automatic master-slave configuration.Each unit ships with parallel communication cables and busbar kits,so expansion requires no additional hardware purchase.The parallel connection supports up to 16units in a single inverter's battery bank for future capacity growth,enabe scalable storage from 32kWh up to 514kWh+ for larger projects.

The MB56 628Ah cells feature a nominal rated capacity of 628Ah,but factory teste typically shows actual capacity between 675-685Ah(approximately 34.5-35kWh per pack before BMS limits).The BMS is configured to expose 32.15kWh as the usable capacity with conservative DOD limits (recommend 80%DOD=approximately 25.7kWh usable per cycle for optimal cycle life).This built-in capacity redundancy acts as a buffer that delays degradation:even after thousand of cycle,it's still deliver its rated 32.15kWh.

We(QSO)offer a one-stop solution. After the purchase, our technical team or certified installation partners will provide remote support to ensure a smooth installation and commissioning. The product is designed as modular and ready-to-use, significantly reducing the complexity of installation.

The QSO 32kWh MB56 628AH DIY BOX includes a standard 5-year manufacturer warranty,extendable to 10years with a paid extension. Coverage includes: 1)manufacturing defects in cells,BMS,and cabinet components; 2)capacity degradation where usable capacity falls below 80% of rated within the warranty period; 3)BMS hardware failure. Exclusions:physical damage from mishandling,unauthorized modification, improper installation,and force majeure events.

Yes. The kit is designed for parallel expansion: you can connect two or more assembled packs on the same 51.2V DC bus to double or triple the total capacity, for example two packs give about 64.3kWh and three give about 96.5kWh. The RS485 and CAN buses support multi-pack communication and monitoring. Please follow the parallel configuration guidelines and confirm the number of packs with us so we can advise on cabling, fusing and BMS settings.
