🌞🔋Introduction to Optical Storage Systems

A photovoltaic storage system is an integrated energy solution that combines a photovoltaic (PV) power generation system with an energy storage system (usually a battery).Its core purpose is:
To use solar power to generate electricity and store the excess power for use when needed, improving energy efficiency and flexibility of power usage.

I. System components

1. Photovoltaic component (PV)

   • Solar panels: convert sunlight to direct current (DC)

   • Photovoltaic racking, convergence boxes, photovoltaic cables, etc.

2. Energy Storage System Segment (ESS)

   • Batteries (lithium, lithium iron phosphate, etc.)

   • Battery Management System (BMS)

3. Energy Management System (EMS)

   • Real-time monitoring and scheduling of power generation and consumption for intelligent control

4. Inverter (PCS or hybrid inverter)

   • Converts direct current to alternating current (AC) for use in the home, business or on the grid

II. Working modalities

• Grid-connected photovoltaic storage systems

  • Priority is given to self-generation and self-consumption, with excess power stored or sold to the grid

  • Reduces electricity bills by releasing battery energy during peak power usage

• Off-grid optical storage systems

  • Not dependent on the power grid, suitable for remote areas, field base stations, etc.

• Microgrid system (multi-energy integration of light-storage-diesel-network)

  • Interacts with the grid, with energy autonomy and fault back-up

III. Advantages

✅ Increased utilisation of new energy sources

✅ Enabling peak shaving and valley filling to reduce electricity costs

✅ Enhance grid-friendliness and reduce reliance on conventional power sources

✅ Increased reliability of electricity consumption by supplying power in the event of a power failure

IV. Application scenarios

• Residential rooftop (household light storage)

• Industrial and commercial parks (industrial and commercial optical storage)

• Remote communication base stations, border posts, island power stations

• Urban smart microgrids, charging stations for new energy vehicles
