In the field of new energy storage, high-voltage energy storage lithium batteriesare becoming a key lever for industrial upgrading. Today, we focus on the ET-51.2V100Ah-HV high-voltage energy storage lithium battery system, delving into its technical parameters, application value, and industry competitiveness to deeply analyze how it leads the development trend of high-voltage energy storage lithium batteries with its reliable, flexible, and intelligent characteristics.
The ET – 51.2V series comes in multiple nominal capacity variants: 200Ah, 280Ah, and 314Ah. Corresponding to these capacities, the nominal energy values are 10.24kWh, 14.34kWh, and 16.08kWh respectively. When considering usable energy (at 90% Depth of Discharge – DOD), they provide 9.22kWh, 12.9kWh, and 14.47kWh. This range of capacities and energy levels makes them suitable for a wide array of applications, from residential energy storage to small – scale commercial use.
The system’s modular architecture is its core advantage for “flexible adaptation”:
Module nominal energy reaches 5.12kWh, with a nominal voltage of 51.2V and a single module capacity of 100Ah.
The number of series modules is optional from 4 to 10 groups, allowing the system nominal voltage to cover 204.8V to 512V, and system energy to scale from 20.48kWh to 51.2kWh (90% DOD usable energy is 18.43kWh to 46.08kWh).
Supports parallel connection of up to 4 groups, enabling a total capacity exceeding 340kWh, perfectly matching diverse needs from commercial & industrial applications to large-scale energy storage power stations.
Cycle Life: Supports ≥ 6000 cycles (at 0.9 discharge depth). Calculated based on one charge-discharge cycle per day, the service life exceeds 16 years, far surpassing the industry average.
Warranty Service: Provides a 5-year free warranty + 5 years of technical support, building a full-cycle reliable experience from product to service.
Equipped with an intelligent Battery Management System (BMS), it can collect core data such as voltage, current, and temperature in real-time, and intelligently regulate charge/discharge power. Simultaneously, it features a WiFi module and display interface, supporting remote monitoring via mobile APP, parameter adjustment, and firmware upgrades, making “unattended” intelligent energy storage a reality.
The high-voltage architecture reduces the number of parallel cells, lowering internal system resistance and thermal losses. The energy conversion efficiency is increased by 8%-12% compared to low-voltage systems. Meanwhile, the modular design shortens project delivery cycles by 30%, significantly reducing the time and economic costs of energy storage projects.
In “integrated wind-PV-storage” projects, the ET-51.2V100Ah-HV can efficiently adapt to the output characteristics of photovoltaic and wind power. Through rapid charging/discharging and intelligent dispatch, it addresses the pain points of “intermittency and instability” in new energy generation, facilitating grid integration and energy structure transformation.
Supports OEM/ODM customization. Parameters like voltage, capacity, appearance, and functional modules can be adjusted according to customer needs. Whether for communication base station backup power, home energy storage, or large-scale power station projects, it can provide “tailor-made” energy storage solutions.
