Product Description

Product Description

COMMERCIAL & INDUSTRIAL ENERGY STORAGE CABINET

Firstly, they adopt LFP (Lithium Iron Phosphate) batteries, ensuring high safety and reliability—critical for long-term industrial operations. The energy capacity ranges from 112.54 kWh to 241 kWh, with high usable energy ratios (e.g., 105.79 kWh usable from 112.54 kWh total), meeting diverse power demand scenarios.

Secondly, the electrical parameters are optimized for industrial grids. Nominal DC voltage spans 358.4V to 832V, with corresponding voltage ranges (313.6V~403.2V up to 728V~949V) to adapt to different grid conditions. Most models feature 100KW rated power and AC 400V rated voltage, compatible with standard industrial power systems.

Thirdly, they are designed as grid-tied systems with MPPT (Maximum Power Point Tracking) functionality (voltage range 200~800V), enabling efficient integration with renewable energy sources like solar panels. Multiple models (e.g., WRES-CI-25-113, WRES-CI-25-215) provide flexible options, allowing users to select based on specific capacity and voltage requirements.

Overall, these products combine safety, flexibility, and grid compatibility, making them suitable for C&I scenarios requiring stable, scalable energy storage solutions.

Functions

Firstly, they enable peak-valley tariff arbitrage. With usable energy ranging from 105.79 to 232 kWh and rated power 50–125 kW, the systems store electricity during off-peak hours (low tariffs) and discharge during peak periods (high tariffs), directly cutting operational energy costs for businesses.

Secondly, they provide reliable backup power. Equipped with safe LFP batteries, the systems maintain stable output (AC400V standard) to power critical equipment (e.g., production machinery, data centers) during grid outages, avoiding downtime losses.

Thirdly, they support renewable energy integration. As grid-tied systems with 200–800V MPPT compatibility, they efficiently store excess solar/ wind power that would otherwise be wasted, boosting self-consumption of clean energy and reducing carbon footprints.

Lastly, they enhance grid adaptability. With wide DC voltage ranges (313.6–949V) and compatibility with industrial power systems, the systems flexibly match different grid conditions, ensuring stable operation even in fluctuating voltage environments.
These functions collectively address C&I users' needs for cost savings, energy security, and sustainability.

Functional Advantages

Firstly, they deliver strong economic value. With usable energy capacities (105.79–232 kWh) and rated powers (50–125 kW) tailored to business scales, the systems enable effective peak-valley tariff arbitrage—storing low-cost off-peak electricity and supplying it during high-tariff peak hours, directly cutting long-term energy expenses for energy-intensive sectors like manufacturing and logistics.

Secondly, they ensure high safety and reliability. Adopting LFP (Lithium Iron Phosphate) batteries, the systems feature excellent thermal stability and long cycle life, minimizing risks of faults or downtime. Stable AC400V output further guarantees uninterrupted power for critical equipment (e.g., production lines, data servers), avoiding costly operational losses from grid outages.

Thirdly, they offer strong adaptability. With wide DC voltage ranges (313.6–949V) and 200–800V MPPT compatibility, the grid-tied systems seamlessly integrate with on-site renewable energy (solar/wind) and adapt to diverse grid conditions. Multiple models (e.g., 112.54kWh, 241kWh capacities) also allow flexible matching to different business energy demands.

Lastly, they support sustainability goals. By storing excess renewable energy and reducing reliance on fossil-fueled grid power, the systems lower carbon emissions, helping businesses meet environmental targets while enhancing brand reputation.

Core Applications

First, they are primarily used for peak-valley tariff arbitrage. With usable energy capacities from 105.79 kWh to 232 kWh and rated powers of 50–125 kW, the systems store electricity during off-peak hours (when tariffs are low) and discharge during peak periods (high tariffs), directly reducing businesses' monthly electricity costs—a critical application for energy-intensive sectors like manufacturing and retail.

Second, they function as backup power sources for critical operations. Equipped with safe LFP batteries and stable AC400V output, the systems ensure uninterrupted power supply to key equipment (e.g., production lines, data servers, refrigeration units) during grid outages, avoiding costly downtime and operational losses for C&I users.

Third, they support renewable energy consumption. Designed as grid-tied systems with 200–800V MPPT compatibility, they store excess electricity generated by on-site solar panels or wind turbines. This prevents energy waste (avoiding "curtailment" of renewable power) and increases self-consumption of clean energy, helping businesses meet carbon reduction targets.

Lastly, they aid in grid stability support. With wide DC voltage adaptability (313.6V–949V), the systems balance fluctuating electrical loads of C&I facilities (e.g., sudden machinery startup), reducing pressure on the public grid and enabling smoother operation—especially for users in regions with unstable grid supply.
