32Kwh 64Kwh Hektary Offgrid 32 Kwh 50 48V Lifepo4 Battery Pack Balkonkraftwerk Speicher/Grid-tied Balcony Energy Storage System

The 32KWH model uses 16 high-quality brand new A-grade MB56 628Ah primatic lithium iron phosphate battery cells.These large-capacity battery cells specifically designed for stationary energy storage.They feature thickened electrode design and support more than 8,000 deep cycles.Each cell undergoes internal resistance testing (≤0.25mΩ),capacity matching (±1% tolerance),and voltage grouping before assembly.support QR code full traceability to the production batch and date.

32KWH battery pack features a nominal voltage of 51.2V and a rated capacity of 628Ah,delivering 32 kilowatt-hours of energy storage.It uses 16 Grade A MB56 prismatic LiFePO4 cells in a 16S1P configuration.Output power range is 30-40KW,making it suitable for whole-house backup,small commercial,and agricultural applications.Actual tested capacity exceeds 640Ah due to our rigorous cell grading process with ±1% tolerance match.The all-in-one design integrates a 300A smart BMS with LCD touch screen.

32KWH battery is rated for 8000+cycle at 80% Depth of Discharge(DOD)under 25°C standard test conditions.After 8000 cycles,the battery retains 70% or more of its original capacity.At 90% DOD with 0.5C charge/discharge rate,testing demonstrates 8000+cycle.For a typical household cycling daily at 80%DOD,this translates to approximately 15-20years of service life.The built-in BMS tracks cumulative cycle count and SOH(State of Health)in real-time,accessible via the LCD touch screen or smartphone app.

The built-in 300A smart BMS supports a comprehensive range of communication protocols:CAN 2.0B (500kbps default, configurable),RS-232, RS-485 (Modbus RTU),WiFi (2.4GHz),and Bluetooth 5.0.This enables seamless integration with major inverter brands including Growatt SPF/SPH series,Sunsynk 5-16kW,Victron MultiPlus-II/Quattro with VE.Can,SMA Sunny Island,Solis hybrid,Luxpower SNA/Tek, Voltronic Axpert MAX/VM,SRNE, MPP Solar,and EASUN. Real-time monitoring of 16 series cell voltages,SOC,SOH.

Up to 16 units of the 32KWH battery can be connected in parallel via the CAN/RS485 communication bus,scaling system capacity from 32KWH to a maximum of 512KWH. The master BMS unit automatically coordinates charge/discharge across all connected packs through an intelligent address protocol.Up to 4 parallel units require no external combiner box.For 8-16 unit installations,we recommend using DC busbars with equal-length cables to prevent circulating currents and ensure balanced load sharing.

The QSO 32KWH battery pack holds the following certifications: CE (EMC Directive 2014/30/EU and LVD Directive 2014/35/EU), RoHS (Directive 2011/65/EU), IEC 62619:2017 (safety requirements for secondary lithium cells and batteries), UN38.3 (transport safety: covering altitude simulation, thermal cycling, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge tests), MSDS (compliant with GHS Revision 8), and EMC EN 61000 series standards.

Primary applications for the QSO 32KWH battery: (1) Whole-house backup power : provides 2-3 days of autonomy for an average 4-bedroom home with 15-25kWh daily consumption, pairing with 10-15kW hybrid inverters. (2) Off-grid living : sufficient for full off-grid households with moderate energy usage, combined with 8-12kW solar arrays. (3) Small commercial/agricultural : powers workshops, small farms, retail stores, telecom towers, and remote monitoring stations requiring reliable 24/7 energy.
