ESS-GRID Solar Battery Cabinet Backup System

ESS-GRID Scalable Battery Storage is built for hybrid energy systems and microgrids with modular design and flexible scalability as its core advantages. The following are its core functions and details:
1. Core functions
Highly scalable architecture
Modular design supports parallel expansion of multiple cabinets. In the case of the ESS-GRID HV Pack, a single cabinet can be flexibly scaled from 39 kWh to 1,866.24 kWh by connecting 16 modules in parallel. The DC side is equipped with dual DC ports as standard, which supports the expansion of 4/6/8 hours of backup power scheme, and the reserved interface on the AC side can realize the parallel connection of 2 units to meet the energy storage needs of different scales.
Smart energy management
Integrate the cloud-edge collaborative EMS system to support real-time monitoring, remote scheduling, and policy optimization. For example, AI algorithms can be used to predict load fluctuations and dynamically adjust charging and discharging strategies to maximize peak-to-valley arbitrage returns. The local control screen can visualize the status of each module in 3D, support one-click switching of on-grid/off-grid mode, and the response time is as low as 150ms.
All-scenario compatibility
Compatible with photovoltaic, diesel generators and grid multi-energy inputs, support on-grid, off-grid and mixed-mode operation. For example, the ESS-GRID C230 can be connected to 150-500kW photovoltaic or diesel power generation power, and output 380-400V three-phase AC power, which is suitable for farms, hotels, data centers, and other scenarios.
Full lifecycle security
Three-level fire protection: PACK-grade fireproof cotton, group-level perfluorohexanone spray, dual-chamber nitrogen inerting system, combined with the physical isolation design of the battery and the electrical unit, to curb thermal runaway from the source.
Intelligent early warning mechanism: The AI cell health management system monitors voltage and temperature in real time, warns of abnormal status, and supports second-level fault location and remote firmware upgrade in the cloud.
High protection level: IP54 protection design (IP55 for some models), stable operation in extreme environments from -20°C to 55°C, suitable for desert, high humidity and other harsh working conditions.
Second, technical characteristics
Long life and high efficiency
Using 314Ah lithium iron phosphate cells, it has a cycle life of more than 6,000 cycles (90% DOD) and a system efficiency of ≥90%. The liquid-cooled temperature control technology controls the temperature difference of the battery cell within ±1.5°C, delays the aging of the battery, and supports reliable operation for more than 10 years.
Plug and play deployment
The integrated cabinet integrates batteries, PCS, EMS, fire protection and temperature control systems, and only needs to be connected to the mains and photovoltaic power after unpacking. The size of a single cabinet is 2438×1820×2400mm, and the weight is 4.7 tons, which supports standard container transportation and fast lifting.
Flexible power interfaces
It supports 400V/690V dual voltage level grid-connected and is compatible with mainstream inverter brands. For example, the ESS-GRID C230 can be matched with 130kW inverters from ABB, Huawei, and other manufacturers, with an output current of 280A, to meet the requirements of high-power loads.  3. Typical Application Scenarios Peak-to-Valley Electricity Price Arbitrage Charging during trough hours and discharging during peak hours, combined with EMS's time-of-use electricity price strategy, can reduce electricity costs by 30%-50%. For example, an industrial park saved more than one million yuan in electricity bills annually by connecting four ESS-GRID 200kWh systems in parallel. Microgrid support provides stable power for remote areas or islands, such as off-grid operation in combination with wind power. The ESS-GRID C230's island mode can independently support a 300kW load with a black start time of < 1 second. Grid Ancillary Services Participate in demand response (DR) and frequency modulation services, such as ±10% of the rated power output in 20ms when the grid frequency fluctuates, improving grid stability. Enterprises with high energy consumption can reduce costs Enterprises such as steel and mining can use the ESS-GRID system to smooth out load fluctuations and reduce electricity demand. For example, a data center uses four ESS-GRID 416kWh systems to reduce peak demand by 25%.

The ESS-GRID Commercial Energy Cabinet is a fully integrated energy storage solution engineered for modern commercial and industrial demands. Available in 100kWh, 200kWh, and 215kWh configurations—with scalability up to 2MWh—it supports grid-tied, off-grid, and hybrid applications across diverse environments like farms, schools, warehouses, and solar parks. Designed with an air-cooled system, IP54 protection, and built-in fire suppression, the ESS-GRID Commercial Energy Cabinet ensures safety, performance, and reliability even in harsh conditions. With smart integration options for PV modules, transformers, and communication interfaces, this cabinet delivers intelligent energy management for your business.

Note: The above models are typical configurations, and can also be used for micro-grid and other scenarios with optional photovoltaic charging modules, switching modules, industrial frequency transformers and other components, integrated optical storage, and integrated system cabinets.
