Energy storage systems play a crucial role in smart grids. Main applications include:
• Power regulation: Provide electricity during peak demand and store it during low demand to balance the load.
• Grid stability: Offer fast-response power support for sudden changes in demand.
• Renewable energy integration: Store electricity generated from solar and other renewable sources to improve energy utilization. FSP's LightUp Series inverters combined with battery systems, or the all-in-one mobile storage system EnerX 3000, effectively integrate solar generation and storage for optimized energy management and improved smart grid performance.

In energy storage systems, common units include:
• Power: Measured in watts (W) or kilowatts (kW), indicating the output capacity of the power conversion system.
• Energy: Measured in watt-hours (Wh) or kilowatt-hours (kWh), indicating the total energy stored in the battery.
• Capacity: Measured in ampere-hours (Ah), representing the amount of electric charge the battery can store.
For example, the EnerX 3000 mobile storage product has a rating of 3kW/2.5kWh, meaning it provides up to 3 kW of output and stores 2.5 kWh of energy.

FSP new energy storage system products focus on the development of distributed energy storage systems that are applied on the power load end to provide real-time backup functions, and avoid the impact of power outages caused to the grid by accidents.

The application fields include home use, residential and commercial complex, industrial plants or microgrids, etc. 
For the applications mentioned above, FSP provides 10 kW to 100kW level energy storage system solutions, and takes the solar output voltage range and power feed/self-use requirements into consideration to build the electricity consumption and output power required for backup or emergency power supply.

The requirements of AC power are Single Phase, Split Phase and Three Phase.
The voltage of a single set of battery is 48V/100Ah, and can be expanded up to 10 sets. 
Power supply sequence: PV has highest priority, then city mains, and then battery backup.

FSP's self-developed PCS features industry-leading Grid-Forming (GFM) technology. Unlike traditional GFL PCS, which can only follow the grid frequency: FSP's GFM PCS can independently generate stable voltage and frequency reference sources, supporting black start and independent microgrid operation. Localized advantages: The product is scheduled to obtain VPC certification, fully complying with Taiwan's grid connection regulations. This effectively reduces reliance on overseas suppliers and provides immediate local after-sales support. Modular architecture: This provides system integrators with exceptional flexibility in space utilization when designing outdoor battery cabinets.

FSP's safety protection designs include:

1. Active BMS monitoring to instantly cut off circuits upon detecting anomalies.
2. Air cooling to maintain optimal operating power ranges.
3. Firmware and physical protection: Safe operational limits in firmware, alongside fuse protections on both AC and DC sides.

FSP's PCS offers high communication compatibility, supporting Modbus TCP/RTU and CANbus standard protocols, enabling seamless integration with mainstream Energy Management Systems (EMS). Its core functions include:

• AFC (Automatic Frequency Control): Automatically compensates power based on grid frequency changes, participating in Taipower's ancillary services.
• Integration with system EMS: Through FSP's proprietary platform, it connects with the system EMS for real-time data monitoring and executing high-level dispatch commands.
• High-precision control: Supports reactive power compensation and power quality improvement, assisting users in achieving peak shaving and reducing electricity costs.

FSP is a Power Supply Total Solution Provider. We offer:

• Integrated Design: Modular power products supporting system integrators with BMS and EMS integrations for rapid All-in-One ESS deployment, reducing installation time.
• Micro-customization & White Labeling: JDM support and localized functional ODM for global clients.
• Field Validation: FSP's Demo Site provides real-world ESS operational data and scenarios, supported by a dedicated technical team.
