51.2V 314Ah 16kWh Standing LiFePO4 Battery

Product Overview

ANJAROEL 51.2V 314Ah vertical standing lithium iron phosphate battery is a high-capacity energy storage unit specially matched with solar inverters and household off-grid energy storage systems. Built with premium LFP cells supporting up to 5000 charge-discharge cycles, it integrates a full set of multi-protection BMS for unattended long-term operation. Rated at 51.2V, 314Ah and 16076.8Wh energy capacity, it features IP54 dust-proof and splash-proof enclosure, optional LCD display and multiple communication ports including RS485, CAN, Bluetooth and WiFi. Certified to UN38.3 and MSDS standards, it delivers stable power in wide temperature and humidity environments, ideal for residential solar storage, commercial backup power and off-grid power stations.

1. Long Service Life & Large Energy Storage

Adopts high-stability LiFePO4 cells with cycle life up to 5000 times, greatly reducing later replacement and maintenance costs. It carries 314Ah capacity with total energy of 16076.8Wh, meeting all-day power consumption of full-house home appliances and small commercial equipment, supporting long-duration energy storage for solar self-consumption.

2. Strong Charging & Discharging Capacity

Supports maximum 150A continuous charging current and 200A continuous discharge current; instant pulse discharge reaches 250A within 1 second to instantly start high-power loads such as air conditioners and water pumps without voltage drop. The operating voltage window covers 44.0V–57.6V, perfectly compatible with mainstream 51.2V hybrid solar inverters on the market.

3. All-Round Multi-Layer Safety Protection

The built-in intelligent BMS realizes full protection against overcharge, overdischarge, overcurrent, short circuit and overtemperature. The product passes UN38.3 transportation safety certification and has complete MSDS documents, effectively avoiding fire, swelling and other safety hazards during charging, discharging, transportation and storage.

4. IP54 All-Weather Environmental Adaptability

IP54 protection grade blocks dust and splashing rain, suitable for indoor and semi-outdoor installation. Working temperature ranges from -20℃ to +60℃, adapting to cold winter and high-temperature summer. It runs normally under 5%–95% non-condensing humidity and within altitude below 1500m, applicable to most regions worldwide.

5. Intelligent Expandable Monitoring Design

Optional LCD screen displays real-time voltage, current, SOC and temperature data. Multiple communication ports (RS232 / RS485 / CAN / BT / WIFI) are available for linkage with inverters and remote mobile APP monitoring. Vertical standing cabinet structure saves installation space, and M6 thick copper terminals ensure stable large-current connection.

1. Household Solar Energy Storage Systems

Match 51.2V hybrid solar inverters to store surplus photovoltaic power generated during the day for night use, cut electricity bills and realize peak load shifting. IP54 casing and wide temperature performance fit indoor garage and outdoor equipment room installation.

2. Commercial & Office Emergency Backup Power

Provide stable backup power for small shops, offices and monitoring equipment during grid blackouts. Large pulse discharge capacity supports air conditioners, servers and cash registers without sudden power failure.

3. Off-Grid Cabins, Villas & Remote Areas

For rural houses, mountain villas and remote areas without stable municipal power grid, it forms independent off-grid power supply system with solar panels to meet daily lighting, refrigeration and living power demand.

4. Industrial Standby & Energy Storage Projects

Suitable for small industrial energy storage projects, supporting parallel expansion to increase total capacity. Multi-communication protocol design facilitates centralized monitoring and intelligent management of multiple battery units.

1. Place the battery on flat, dry and ventilated ground, reserve enough heat dissipation space around the cabinet, and avoid blocking air vents.

2. Connect positive and negative poles via M6 terminals with matched copper lugs, strictly prevent reverse connection.

3. Use dedicated LiFePO4 solar inverter or charger with float voltage set to 56.0V.

4. Connect communication lines to inverters or monitoring equipment if LCD and wireless monitoring functions are required.

5. For long-term storage, store under 0℃~30℃ environment and recharge every 6 months to maintain battery activity.

6. Do not use the battery beyond the working temperature, humidity and altitude limits to avoid triggering BMS protection.

Q1: Can this battery be used with most solar hybrid inverters? 

A1: Yes, the 44.0V–57.6V operating voltage range matches mainstream 51.2V low-voltage solar inverters on the market, and multi communication ports support signal linkage.

Q2: What’s the maximum instantaneous power it can bear? 

A2: It supports 250A pulse discharge within 1 second, which can instantly start high-power inductive loads such as air conditioners and water pumps.

Q3: Can it be installed outdoors? 

A3: With IP54 dustproof and splashproof rating, it can be placed in semi-outdoor covered areas, but avoid long-term direct exposure to heavy rain and water immersion.

Q4: How long can the battery be stored without charging? 

A4: It can be stored for up to 6 months under 25℃ ambient temperature; supplementary charging is required after 6 months to protect cell performance.
