Hebei Mutian Solar Energy Technology Development Co., Ltd. is one of the most reliable manufacturers and suppliers of 30kwh lifepo4 battery in China, also supports customized service. Welcome to buy advanced 30kwh lifepo4 battery in stock from our factory.
Precision Engineering Meets Real‑World Performance
The core of this system is made up of innovative lithium iron phosphate (LiFePO₄) cells that are known for their high level of heat tolerance and durability, with longer life spans than standard lead acid batteries or many types of nickel lithium oxide (LiNiCoMn) batteries. The 30KWH LiFePO4 Battery will provide you with constant voltage throughout the discharge cycle, allowing your inverters and sensitive electronic equipment to always be maintained within their acceptable voltage ranges. This particular battery should give you approximately 8,000 cycles when discharged 80% of its total capacity, which is equivalent to about 20 years of use with daily usage under normal conditions in the residential environment. As a result, the lifespan of the LiFePO₄ battery will reduce your overall cost of ownership by eliminating the need to replace your batteries on a regular basis.
Intelligent Connectivity & User‑Centric Control
Today's energy management has moved beyond just measuring amps per hour as modern energy managers measure additional variables when managing their energy sources. Modern energy managers utilize three types of communication interfaces, RS232, RS485, and CAN Bus, to connect to Hybrid Inverters, Solar Charge Controllers and Building Management Systems for monitoring all of their parameters in real time; for example; state of charge, state of health, cell voltages, temperature and historical logs.
Comprehensive Protection – Safety Without Compromise
Safety is non‑negotiable in energy storage, and this battery leaves nothing to chance. The integrated Battery Management System (BMS) monitors every cell group with millivolt precision, offering automatic protection against:
Over‑voltage – stops charging when any cell exceeds 3.65V (system threshold 58.4V).
Low‑voltage – disconnects load when pack voltage drops to the programmable cut‑off range (44.8V – 46.5V), preserving cell health.
Over‑current – instantaneous current limiting for both charge and discharge paths.
Short‑circuit – hardware‑based fast isolation to prevent catastrophic failure.
Over‑temperature – thermal sensors embedded at multiple points; the BMS reduces current or shuts down if internal temperature strays outside the operating envelope (-20°C to +60°C).
Reverse polarity – robust diode protection against accidental cable misconnection.
The industrial grade steel enclosure is designed for areas with up to 95% humidity (non-condensing), as well as being able to function at an altitude of 4000 meters. The battery's performance will remain consistent, regardless of whether the battery is located indoors (basement/garage), or in weatherproof outdoor enclosures for long periods of time.

Versatile Applications – One Battery, Countless Uses
This 30KWh system is purpose‑built for:
Solar / Wind Energy Storage
Store daytime surplus and discharge during evenings or cloudy periods. Recommended solar array > 6,000 Wp (with average daily insolation > 6 hours) to fully recharge the bank.
Communication Equipment
Telecom towers, microwave relays, and data centres benefit from the battery's stable voltage and rapid response to load changes.
Emergency Power & UPS
Keep servers, security systems, and life‑safety equipment running through grid disturbances. The battery switches from charge to discharge in milliseconds.
Medical Facilities
Power ventilators, monitors, and imaging devices with pure sine‑wave compatibility (when paired with a suitable inverter).
Fire & Security Systems
Uninterrupted power for alarm panels, access control, and surveillance cameras – critical for 24/7 protection.
Off‑grid Residences & Mobile Homes
Eliminate generator noise and fuel dependency; enjoy silent, emission‑free electricity.
Installation, Expansion & Maintenance
The battery comes as a complete, pre‑assembled unit with heavy‑duty terminals and a clear wiring diagram. The compact 680×380×700 mm footprint allows for easy placement against walls or inside standard racks. For higher energy needs, up to 15 units can be paralleled (with proper busbars and master‑slave communication), scaling your storage capacity to over 460 kWh – sufficient for whole‑estate or micro‑grid applications.
Maintenance is limited to visual inspection of terminals/ventilation holes every few months (both visually and physically) as well as updating the firmware using the APP. All cells are self-balanced due to the BMS, so no external active balancing is required, thereby meaning the user has very little need to maintain the battery.
Why Choose This LiFePO₄ Battery?
Exceptional energy density – 30 kWh is compressed into 227 kg – lighter than comparable lead acid battery banks.
