FAQ
What is this movable lithium battery pack used for?
It is designed for solar energy storage, off-grid power supply, RV systems, commercial facilities, industrial equipment and emergency power applications, working together with a compatible inverter.
What capacity options are available?
Two options: 17.7kWh (MB 512346, 346Ah) and 26kWh (MB 512519, 519Ah), covering different backup time and load requirements.
What type of battery cell does this product use?
LiFePO4 lithium iron phosphate cells, known for high safety, long cycle life, stable performance and good thermal stability.
What is the rated voltage of this lithium battery pack?
51.2V (16S configuration), suitable for compatible inverter-based power and energy storage systems.
Does the battery pack include BMS protection?
Yes. A built-in BMS provides protection against overcharge, over-discharge, overcurrent and abnormal operating conditions.
What communication interfaces are supported?
RS485, RS232 and CAN, for integration with compatible inverters and energy management systems.
How many cycles can the battery support?
Up to 6000 cycles under 75% DOD at 25°C.
What is the rated output power?
The rated output power is 10,000W, suitable for high-capacity backup power and energy storage scenarios.
Which unit should I choose, 17.7kWh or 26kWh?
Choose by daily energy consumption and required backup time: MB 512346 (17.7kWh) fits lighter loads, MB 512519 (26kWh) extends runtime for heavier or longer-backup applications. Send your load profile and ShanPu confirms the sizing.
