Highjoule Invites You to the 2025 Autumn Canton Fair

Rated power indicates the maximum instantaneous discharge capability of the system, typically measured in kilowatts (kW) or megawatts (MW).
Energy capacity refers to the total amount of energy that can be stored, usually expressed in kilowatt-hours (kWh) or megawatt-hours (MWh).

Peak-valley arbitrage
Leverage differences in electricity pricing between peak and off-peak hours to charge the system during low-cost periods and discharge during high-cost periods, effectively reducing energy expenses.

Reduce demand charges
Energy storage can flatten load peaks and smooth power demand curves, helping businesses reduce costly demand-based electricity charges.

Dynamic capacity expansion
When the existing transformer capacity is insufficient during certain peak periods, energy storage systems can supplement power without requiring transformer upgrades, saving on infrastructure investment.

Demand response participation
Energy storage enables participation in grid demand response events, providing backup during peak grid demand and generating compensation, without impacting business operations.

General info: electricity type, base tariff, time-of-use electricity pricing, and production schedules during power outages.

These details help design charge/discharge strategies, determine tariff-based vs. demand-based models, assess storage usage times, and align with production cycles.

Load data: annual power consumption patterns, average and peak loads, transformer capacity.

This helps estimate the optimal system capacity, align with transformer limits, and develop charge/discharge logic and economic models.

Engineering documentation: power distribution diagrams, plant layout, substation schematics, cable routes, and available installation space.

These are crucial for determining system placement, transformer connection points, and access plan design.

The sum of energy storage charging power and the enterprise’s peak load must be below 80% of the transformer's rated capacity to prevent overloads.

Daytime peak load should exceed the maximum discharge power to ensure cost-effective discharge scheduling.

Monthly or annual power use alone is insufficient—detailed daily load profiles are essential to calculate system sizing accurately.

If an enterprise has a single transformer, then total load data typically reflects the transformer's actual load, and a preliminary system size can be estimated. However, if multiple transformers are involved, the aggregate data may not reflect individual transformer loads. In such cases, separate load data for each transformer is required to accurately determine system sizing.

Yes. Industrial and commercial PV-storage integration projects often use AC-coupled configurations. With Highjoule’s intelligent EMS, real-time monitoring of integrated storage cabinets and PV inverters allows for optimized energy use under "load-first" strategies, enhancing PV utilization efficiency.

Home energy storage systems store solar-generated electricity during the day for use at night or during peak pricing periods. This reduces reliance on grid power and lowers electricity costs, especially in regions with time-of-use pricing.

The service life of most home energy storage systems ranges from 10 to 15 years. Lifespan depends on battery type, usage patterns, and maintenance. Highjoule products include long-term warranties to ensure system reliability over time.

Highjoule's base station storage solutions adopt a redundant power design that enables rapid switching to backup supply during outages or fluctuations. Intelligent monitoring and automated control systems maintain 24/7 uptime, ensuring consistent communication operations.

Highjoule energy storage solutions are modular and flexible, allowing seamless integration with various base station configurations. The scalable design simplifies installation and accommodates future expansion needs while minimizing disruptions to existing infrastructure.
