60kWh Energy Storage Battery and Solar Panel/Inverter Operating Principles

With the advancement of renewable energy technology, solar energy storage systems are increasingly being adopted in residential, commercial, and industrial applications. The video demonstrates the operating principles of a 60kWh battery, inverter, and solar panel, offering a critical solution for achieving efficient energy utilisation and energy independence. Below, we will provide a detailed analysis of its operating principles and advantages.

1. Photovoltaic Power Generation — Converting Sunlight into Electricity

Solar panels (PV Solar Panels) convert sunlight directly into direct current (DC) when exposed to sunlight. The amount of electricity generated depends on factors such as sunlight intensity, component efficiency, and installation angle. During daylight hours with ample sunlight, the photovoltaic panels continuously generate electricity, providing the entire system with clean, renewable energy.

2. Inverter Conversion — DC to AC

Since household appliances and industrial equipment typically use alternating current (AC), the DC electricity generated by photovoltaic panels must be converted into AC electricity via an inverter. This process not only converts electrical energy but also monitors power generation, load power, and battery status in real-time, ensuring the system operates safely and stably.

3. Energy Storage — 60kWh Battery Stores Excess Electricity

During the day, when photovoltaic power generation exceeds current load demand, excess electricity is stored in a 60kWh energy storage battery. This capacity is sufficient to support household or small-to-medium-sized commercial loads for several hours or even an entire night.

Battery Charging Phase: Efficiently stores DC electricity to minimise waste.

Battery discharge phase: When photovoltaic power generation is insufficient (e.g., at night or on cloudy days), the inverter converts the DC power from the battery into AC power to continue supplying power to the load.

4. Grid connection and revenue — Selling excess electricity to the grid

When the battery is fully charged and there is still excess power generation, this excess energy can be fed back into the public grid via the grid connection system, earning electricity compensation or revenue (depending on local grid connection policies and electricity pricing mechanisms). This not only improves energy utilisation but also generates additional economic returns for users.

5. System operating modes in different scenarios

During daylight hours with ample sunlight, Photovoltaic power generation prioritises supplying loads, with excess energy stored in the battery or sold to the grid.

At night or during cloudy/rainy weather, the battery discharges to meet load power requirements.

During power outages, the energy storage battery serves as a backup power source to ensure the operation of critical loads such as lighting, communication, and medical equipment.

6. System Advantages

Peak Shaving and Valley Filling: Store energy during off-peak hours and discharge during peak hours to effectively reduce electricity costs.

Energy Independence: Reduce reliance on the grid and enhance energy security.

Green and environmentally friendly: Maximises the use of solar energy, reducing fossil fuel consumption and carbon emissions.

Flexible scalability: Energy storage capacity can be expanded according to actual needs, adapting to future growth in electricity demand for households or businesses.

The organic integration of a 60kWh energy storage battery with solar panels and inverters not only achieves efficient utilisation of clean energy but also provides users with a stable power supply and economic benefits. As energy prices fluctuate and environmental policies advance, such systems will become increasingly widespread globally.
