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.
