Adopts standard 19-inch rack-mounted design, which can be freely stacked vertically and expanded in parallel. Up to 63 modules can be paralleled to meet the energy storage needs of different scales, saving installation space and reducing deployment costs. It is suitable for limited-space scenarios such as data centers and machine rooms.
Uses LiFePO4 battery cells with cobalt-free formula, featuring excellent thermal stability and no risk of thermal runaway. Built-in aerosol fire extinguisher and multi-layer protection mechanisms (overcharge, over-discharge, over-current, short-circuit, over-temperature protection) to ensure safe and stable operation in harsh environments.
Used in hospitals, shopping malls, factories and other places, providing emergency power support during grid failures to ensure the normal operation of key equipment.
Q: How many modules can this 48V 200Ah rack-mounted battery be paralleled with?
A: Up to 63 modules can be paralleled, which can flexibly expand the energy storage capacity according to actual needs, and is suitable for energy storage projects of different scales from residential to small commercial.
Q: What is the difference between this battery and traditional lead-acid batteries?
A: Compared with traditional lead-acid batteries, it has obvious advantages: longer cycle life (6000+ times vs. 1000-2000 times), lighter weight, smaller volume, no need for regular watering maintenance, lower self-discharge rate, higher efficiency, and better safety. It can save space and reduce long-term use costs.
Q: What is the charging and discharging temperature range of the battery? Can it be used outdoors?
A: The charging temperature range is 0~55℃, and the discharging temperature range is -20~55℃, which can adapt to most outdoor and indoor environments. The protection level is IP22, which can effectively prevent dust and dripping water, and is suitable for outdoor telecommunication base stations and photovoltaic power stations.
Q: Does the battery need regular maintenance? What are the maintenance points?
A: The battery adopts maintenance-free design, no need for regular watering or other complicated maintenance. The daily maintenance only needs to check the installation tightness of the battery, keep the surface clean and dry, avoid exposure to high temperature, high humidity and corrosive environments, and check the running status through the monitoring system regularly.
Q: What is the warranty policy for this battery?
A: We provide a 10-year warranty service. During the warranty period, if the battery has quality problems (non-human damage), we will provide free repair or replacement services. The warranty period is calculated from the date of delivery, and the specific warranty terms shall be subject to the official warranty agreement.
Q: Can the battery be stacked arbitrarily? Is there a limit to the number of stacked layers?
A: The battery is designed for stackable installation, but it is recommended to stack no more than 4 layers. Excessive stacking will increase the pressure on the bottom battery, which may affect the service life and safety. It is recommended to install according to the official installation guide to ensure stable operation.
