Features of 11.6-34.8kWh 51.2V 228Ah All-in-One Energy Storage System
11.6-34.8kWh Capacity Options with a 6.5kW Inverter
All configurations use the same 6.5kW inverter. Additional battery modules can be added when more storage capacity is needed. Distributors and installers can cover projects of different sizes with one inverter model, simplifying stock management and system planning.
| Configuration de la batterie | System Capacity | Inverter Output | Recommended Application |
|---|---|---|---|
| 1 × LFP51228S | 11,6 kWh | 6.5kW | Daily solar energy storage and basic backup |
| 2 × LFP51228S | 23.2kWh | 6.5kW | Higher daily energy use or longer backup time |
| 3 × LFP51228S | 34.8kWh | 6.5kW | Frequent power outages or off-grid projects |
For systems operating close to the inverter’s rated output for extended periods, or powering loads with high starting currents, two or more battery modules are recommended.
11.6kWh-34.8kWh LiFePO4 Battery with Smart BMS
Each LFP51228S battery module is rated at 51.2V 228Ah and includes a smart BMS that continuously monitors cell status and provides protection against overcharge, over-discharge, short circuits, and abnormal temperatures. With a cycle life of more than 6,500 cycles, the battery is built for long-term energy storage.
The recommended charging current is 40A, with a maximum of 100A. The recommended discharge current is 100A, with a maximum of 200A and a peak discharge current of 205A for 5 seconds. For projects involving pumps, motors, or other loads with high starting currents, the required battery configuration should be confirmed based on the load power and starting current.
Dimensions, Installation and Operating Conditions
The 11.6-34.8 kWh all-in-one system supports both stacked and wall-mounted installation, allowing installers to choose the arrangement that best fits the available space. It operates from 0°C to 55°C and has an IP21 protection rating. The system should be installed in a dry, well-ventilated indoor location with sufficient clearance for wiring and future maintenance.
| Configuration de la batterie | System Capacity | Dimensions (W × D × H) | Approx. Weight |
|---|---|---|---|
| 1 × LFP51228S | 11,6 kWh | 483 × 260 × 982mm | 108kg |
| 2 × LFP51228S | 23.2kWh | 483 × 260 × 1472mm | 193kg |
| 3 × LFP51228S | 34.8kWh | 483 × 260 × 1962mm | 278kg |
6500W PV Input with Solar, Grid and Generator Support
The inverter supports up to 6500W of PV input, with an MPPT operating voltage range of 60–450VDC and a maximum PV open-circuit voltage of 500VDC.
During the day, solar power can supply your loads first while excess energy is stored in the battery. At night or when solar generation is insufficient, the battery supplies the remaining power. Grid or generator input can also be used to suit weak-grid and off-grid installations.
10ms Switching and Dual AC Output
The inverter provides 6.5kW rated output and 10kVA surge power. Its switching time of approximately 10ms allows the system to transfer quickly to battery power during a grid outage, reducing the impact of brief interruptions on essential loads.
Dual AC outputs allow essential loads to be connected separately from higher-power equipment such as air conditioners and water heaters. This makes it easier to allocate stored energy based on load priority and extend backup time for essential equipment.
Local Display, Communication and Wi-Fi Monitoring
The battery module has a 4.3-inch touchscreen, while the inverter uses a 3.5-inch LCD. Installers can check operating status, identify system alerts, and complete commissioning directly on site.
RS232, RS485, and CAN communication interfaces are provided, with an external Wi-Fi module available as an option. Through Wi-Fi monitoring, installers and end users can remotely view solar generation, battery status, and energy consumption data.
Certifications and 10-Year Warranty
The 11.6-34.8 kWh all in one series has completed CE, KC, UN38.3, and IEC 62619 certification and testing. Relevant certificates and test documents can be provided to support product approval, project tenders, and customs clearance.
The product comes with a 10-year warranty. Warranty coverage, service procedures, and required technical documents can be confirmed before ordering for different markets and projects.
Applications
The system can be used for:
• Residential solar self-consumption and home backup
• Areas with unstable grids or frequent power outages
• Off-grid homes, farms, and remote sites
• Residential projects requiring longer backup time
• Backup power for shops, clinics, and small offices
