Battery energy storage systems have significant advantages when combined with renewable energy systems such as photovoltaics or wind energy, as the peak generation time of these systems may not necessarily be synchronized with user demand time. Therefore, using these devices can store excess electricity and then use or feed it into the grid when needed.

Battery energy storage is one of the most efficient technologies in the power production chain. They can avoid waste and fully utilize the potential of renewable energy and distribution networks. During low demand periods, excess electricity is stored in batteries or sent to the grid, while during peak demand periods, energy storage batteries are discharged and supplied to users, achieving efficient energy utilization.

The energy storage device is installed in a special container connected to the power grid and equipped with advanced safety measures, such as using a battery pack level fire protection system, using perfluorohexane fire extinguishing agent, and each battery pack is designed with an independent fire protection pipeline. The EMS intelligent management system can perform local HMI or remote APP&Web operations on energy storage devices to check their operation and take safety measures when maintenance is required.

Battery energy storage has excellent characteristics,

1) Uninterruptible power supply

RHE energy storage devices can be used as a continuous energy source, but can also be used as backup energy to ensure uninterrupted household energy supply.

2) Optimize electricity usage

By taking advantage of the time difference in electricity prices, peak shaving and valley filling can be achieved, energy costs can be reduced, economic benefits can be obtained, and quantity demand can be monitored and regulated.

3) Reduce energy costs

Solar energy is a clean energy source with zero cost, which can convert solar energy into electricity and reduce energy costs.

Energy storage systems meet the needs of end-users by storing electricity from the renewable energy plants they are connected to, and excess electricity can be uploaded to the grid connected city power grid. The battery energy storage system has a certain function as a grid regulator.

The designed service life is usually based on a charge and discharge life of over 6000 cycles, with approximately 10 years of use per day; The battery pack can be replaced by simply unplugging the cable connector and reinstalling up to 10 bolts. The replaced battery pack can be recycled at a discounted price.

When not in use, you can directly turn off the device or let the solar energy keep charging the battery. After the battery is fully charged, the charging will automatically stop.

No installation required, the power output panel is equipped with quick sockets, wiring copper bars, etc., plug and play, convenient and fast.

No need for regular maintenance. After the first debugging, only the dust on the power board needs to be cleaned every month. The battery is maintenance free, the inverter is maintenance free, and the system needs to be charged and discharged once a month to activate the memory.

PowerLink’s EnerWEB can be used for remote control on the APP or WEB end.

PowerLink energy storage products can be divided into two categories: hybrid systems and microgrid systems, which can be selected according to application scenarios.

There are three major series of mobile hybrid products, with different specifications, control logic, functional scope, and application scenarios. It is necessary to determine our application requirements and then match the functions of each series of products according to these major requirements.

The mobile microgrid series products have 3 major series and 14 application scenarios, including 10 for low voltage systems and 4 for medium to high voltage systems. They can operate in parallel and off grid environments, and have obvious advantages in peak shaving and frequency regulation, peak valley arbitrage, green power de oiling, and uninterruptible power supply applications. Based on the application scenarios, the major product categories are selected and matched with specific model specifications.

We can provide you with investment return analysis reports, operational cost analysis reports, as well as a complete turnkey solution for mobile photovoltaic power generation, balanced hybrid and microgrid stability and investment balance diesel generator selection and supply. We also offer installation guidance, debugging, training, and product lifecycle management services.

They can work together and have significant effects in peak shaving and frequency regulation, peak valley arbitrage, and energy cascade utilization. Coupled with photovoltaic power generation, the cost is further reduced.

Nonlinear data indicates that the load may experience sudden increases or decreases. For energy storage batteries, the outstanding advantage is to stabilize the frequency and voltage quality of the power grid, making the voltage and frequency output of the power grid more stable.

The discharge rate of the unit changes with the load, and how many KW the load is, how many KW the discharge will be. However, the maximum discharge power cannot exceed the rated power of the unit.

About 2%

Yes, our EMS control system has a battery peaking mode.

PES only has three-phase output, RHE12S and RHE24S in the RHE series have single-phase output, while other products have three-phase output. Three phase and single-phase cannot be output simultaneously

Solar photovoltaic panels can be connected in series with a voltage range of 250V-900V. They can be connected to our photovoltaic inverters or multiple interfaces of hybrid and microgrid products through MC4 connectors. The voltage range of the photovoltaic array needs to match the voltage range received by each hybrid and microgrid product. Powerlink has also launched a mobile photovoltaic power generation product specifically designed for mobile hybrid and microgrids, which is plug and play and can be freely combined according to power requirements.
