Background of the Rise of Residential Energy Storage Systems

The world attaches great importance to renewable energy and smart grids. With the promotion of initiatives such as the “Million Solar Roofs Plan” in the United States and the “Energy Transition” in Germany, the government provides high subsidies for the private use of photovoltaic power. As a result, households can achieve self - sufficiency in electricity and store surplus electricity, which is particularly prominent in the residential energy storage market in Germany and Europe. In today's era of rapid development of intelligence and information, the global electricity demand is growing explosively, bringing energy supply, pollution and consumption problems. Photovoltaic power generation is favored around the world. Thanks to policy support and the reduction of power generation costs of photovoltaic energy storage technology, residential photovoltaic power generation and energy storage systems have entered thousands of households. It can not only help households achieve self - sufficiency in electricity and reduce dependence on traditional power grids, but also store electricity for emergencies during peak periods of low power consumption.

Basic Structure and Working Mode of Residential Energy Storage System

Grid - connected Residential Energy Storage System Components: Solar cell array (the core, which converts solar energy into direct current, considering conversion efficiency, etc.), grid - connected inverter (converts direct current into alternating current, is compatible with household electrical equipment, and monitors and manages the operating status of the system), BMS management system (monitors the status of the battery pack and balances charge and discharge), battery pack (stores electrical energy, and its capacity, etc. affect energy storage capacity and service life. Commonly used batteries include lead - acid batteries, lithium - ion batteries, etc.), AC load (household electrical appliances). Working Modes: Mode 1: Photovoltaic provides energy storage and surplus electricity to the grid; Mode 2: Photovoltaic provides energy storage and electricity for some users; Mode 3: Photovoltaic only provides partial energy storage and does not transmit power to the public grid.

Off - grid Residential Energy Storage System Main Components: Solar array, photovoltaic inverter (has more functions in an off - grid system), BMS management system, battery bank, AC load. Working Modes: Mode 1 (sunny days): Photovoltaic provides energy storage and user electricity; Mode 2 (cloudy days): Photovoltaic and energy storage batteries provide users with electricity; Mode 3 (evening and rainy days): The energy storage battery provides users with electricity. Off - grid systems are suitable for areas where the grid is unstable or unavailable, and have higher requirements for battery bank capacity and management systems.

The Role of Battery Management System (BMS) in Residential Energy Storage Systems

The BMS is the “brain” and is of crucial importance. Main Functions: Data collection and monitoring (collect key parameters and current through real - time communication between the BCU and BMU modules), state estimation (calculate the state of charge of the battery and the remaining battery power based on the collected data), user interaction (display the real - time battery status, etc. through user interfaces such as touch screens). System Intelligent Management: Intelligent interaction (the BCU intelligently interacts with other system components through an independent CAN bus), safety control (the BMS implements secondary protection of charge and discharge through relays. When abnormal, the power is cut off to ensure the isolation of strong and weak electricity).

The Core of the Power Solution of the BMS of the Energy Storage System: Isolation Voltage Conversion

The key to the power solution design of the BMS is safe and efficient isolation voltage conversion. When the main control unit is based on a 24VDC system and the power requirement is less than 5W, a suitable power supply product can be used. For example, a power supply product can output 5VDC voltage to power the isolation module and low - dropout linear regulator (LDO). The LDO converts the 5VDC voltage to 3.3V to power the microcontroller (MCU). Multiple isolation modules in the system provide power for the CAN communication module, voltage and insulation detection circuit, and current detection circuit, and isolate the power circuit from the signal circuit and communication module to reduce electromagnetic interference and improve stability. Automotive - grade power supplies are widely used in vehicle BMS systems for vehicle battery management due to their excellent performance and stability.

In short, the residential energy storage system is an important link between the home and new energy. Its structure, working mode, battery management and power solution play a key role in the efficient utilization, stable supply and sustainable development of home energy. With the continuous advancement of technology and the promotion of applications, the residential energy storage system is expected to play a greater value in the future energy field.

Home Solar Electric System

Home Solar Electric System Nerang reduce your reliance on the grid and help you save on electricity bills.

The first step is to assess your home's energy potential. Several mapping services are available to help with this.

The electricity generated by your solar system flows through a power meter and either stays in your house or goes back into the utility grid. Some utilities have varying rates that change as consumption increases.

Solar Panels

Home solar electric systems provide clean, renewable energy to offset electricity costs from the grid. Most electricity comes from fossil fuels, which create pollution that contributes to global warming and a variety of health issues.

To determine if solar is right for your home, first evaluate how much energy you use and how many hours of peak sunlight you receive. You will also want to consider potential efficiency upgrades before making the final decision to go solar.

Solar panels are most effective on homes that can maximize their sun exposure, ideally with a south-facing roof without trees or other obstructions. More complex deployments include motor-driven trackers that orient the panels following the daily and seasonal movement of the sun.

Solar panels don’t work at night or during inclement weather, so you will need to install a battery backup system (or maintain your connection to the power grid). Solar incentives, including tax credits and cash rebates, reduce system costs.

Inverters

The inverter converts the direct current from your solar panels into alternate current (AC) to power appliances in your home. It can also feed energy back into the grid or battery storage system depending on your set up.

It’s essential that your inverter is sized correctly to match the output of your solar panel array. A small inverter won’t be able to handle the power your panels produce, leading to inefficiencies and performance issues. An inverter that’s too large will waste money on idle current while imposing unnecessary loads on your energy system.

Some appliances like washing machines, water pumps and air-conditioners require a high surge during startup. Inverters with poor surge capability will struggle to power these appliances and may fail. An inverter with an internal protection relay can help reduce this risk.

Batteries

Adding solar batteries to your home can make your energy system more resilient in case of grid outages. They can also help you save money on your electricity bill when utility rates are higher at night or during times of high demand.

Batteries store DC electricity from your solar panels, and an inverter-charger converts this to alternating current (AC) that can power appliances. You can add batteries to an existing solar electric system or install them together with your rooftop solar panels in a new installation.

There are a variety of battery technologies, including flooded lead acid and lithium iron phosphate. Flooded lead acid batteries require regular maintenance to check their water levels. Lithium iron phosphate batteries are spill-proof, and they have an average lifespan of 10 years. Some batteries, like LG Chem's PWRcell, have a backup gateway that disconnects the home from the grid. This can be helpful for homes in regions prone to extreme weather conditions.

Electrical Panel

The electrical panel—also called a distribution board, breaker box or electric panel—is the heart of your home's electricity system. It contains rows of switches that control electricity for your home and major appliances like your washer, dryer and refrigerator.

Solar panels convert sunlight into direct current (DC) electricity via the photovoltaic effect. The DC electricity is converted to alternating current (AC) by solar inverters before it is used in your home.

If your home has a grid-tied solar energy system, excess power from your solar panels is pushed back into the grid to earn money through net metering. Your local utility company will send a representative to inspect your solar system and approve the interconnection. This typically takes up to 60 days. Before you choose an installer, request a detailed estimate for the total cost of your solar system—including labor, permit fees, sales taxes and utility fees. Ideally, pay for your solar system upfront to avoid any interest charges.

When the power consumption decreases, the generation power decreases accordingly. It is monitored by current sensors & the ARPC unit. It is necessary so that the excess generated energy does not go into the network and is not counted by the meter as consumed. Domestic electricity meters are one-way and do not know how to subtract. With the introduction of the "green tariff", when it becomes possible to sell surplus electricity to sales companies, then these restrictions will disappear, and it will be possible to earn additional money.

Prerequisites for work

A feature of the work of network inverters is the need for a regular electrical network.

The line of 3-phase inverters consists of devices of different capacities: from 1 to 66 kW. Almost every inverter has 2 independent MPPT trackers built-in with the possibility of uneven power distribution, except the 55 and 66 kW models, which have 3 MPPT trackers.

The presence of the WI-FI module allows you to connect the inverter to the Internet and monitor the system parameters after registration on the manufacturer's website.

Three-phase solar edge inverter is very common in industrial enterprises, office buildings, business centres, country houses, or other facilities where there is electricity consumption in the daytime & there is an external power grid. The use of network inverters can significantly reduce energy costs, and the payback is only from 1 year to 5 years.

Currently, an increasing number of network operators in various countries are setting limits on the return of energy to the urban network from photovoltaic modules. Thanks to the dynamic reduction in power, Solaredge Inverter offers a solution for optimal management of power generation and output. The inverter first supplies electricity to the household consumers in your home & then reduces the output power of the system to the maximum allowable value allowed by the network operator.

Essential knowledge of solar photovoltaic power generation

1. The composition and principle of solar photovoltaic system

The solar photovoltaic system consists of the following three parts: solar cell components; charge and discharge controllers, inverters, test instruments and computer monitoring and other power electronic equipment and batteries or other energy storage and auxiliary power generation equipment.

Solar photovoltaic systems have the following characteristics:

no rotating parts, no noise;

No air pollution, no waste water;

no combustion process, no fuel required;

Simple maintenance and low maintenance cost;

Good operational reliability and stability;

The solar cell as a key component has a long service life, and the life of the crystalline silicon solar cell can reach more than 25 years;

It is easy to scale up power generation as needed.

Photovoltaic systems are widely used, and the basic forms of photovoltaic system applications can be divided into two categories: independent power generation systems and grid-connected power generation systems. The main application areas are mainly in aerospace aircraft, communication systems, microwave relay stations, TV turntables, photovoltaic water pumps and household power supply in areas without electricity and power shortages. With the needs of technological development and sustainable development of the world economy, developed countries have begun to promote urban photovoltaic grid-connected power generation in a planned way, mainly building household rooftop photovoltaic power generation systems and MW-level centralized large-scale grid-connected power generation systems. The application of solar photovoltaic systems has been vigorously promoted in transportation and urban lighting.

The scale and application form of photovoltaic systems are different. For example, the scale of the system is very large, ranging from 0.3-2W solar garden lights to MW-level solar photovoltaic power stations, such as 3.75kWp household roof power generation equipment and Dunhuang 10MW project. Its application forms are also various, and it can be widely used in many fields such as household, transportation, communication, and space applications. Although photovoltaic systems vary in size, their composition and working principles are basically the same. Figure 4-1 is a schematic diagram of a typical photovoltaic system supplying a DC load. It contains several main components in the photovoltaic system:

Photovoltaic module square array: It is composed of solar cell elements (also called photovoltaic cell modules) in series and parallel according to the system requirements. It converts solar energy into electrical energy for output under sunlight irradiation. It is the core component of the solar photovoltaic system.

Storage battery: store the electrical energy generated by the solar cell element, and release the stored electrical energy to meet the energy demand of the load when the light is insufficient or at night, or when the load demand is greater than the power generated by the solar cell element. It is the storage battery of the solar photovoltaic system. capable parts. At present, lead-acid batteries are commonly used in solar photovoltaic systems. For systems with higher requirements, deep-discharge valve-regulated sealed lead-acid batteries, deep-discharge liquid-absorbing lead-acid batteries, etc. are usually used.

Controller: It regulates and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell element and the battery to the load according to the power demand of the load. It is the core control part of the entire system. With the development of the solar photovoltaic industry, the functions of the controller are becoming more and more powerful, and there is a trend to integrate the traditional control part, inverter and monitoring system. For example, the controllers of AES' SPP and SMD series integrate the above three a function.

Inverter: In the solar photovoltaic power supply system, if there is an AC load, an inverter device is used to convert the DC power generated by the solar cell element or the DC power released by the battery into the AC power required by the load.

The basic working principle of the solar photovoltaic power supply system is to charge the battery with the electric energy generated by the solar cell element through the control of the controller under the irradiation of sunlight, or directly supply power to the load when the load demand is met. Then, the battery supplies power to the DC load under the control of the controller. For a photovoltaic system containing an AC load, an inverter needs to be added to convert the DC power into an AC power. The application of photovoltaic systems takes many forms, but the basic principles are similar. For other types of photovoltaic systems, the control mechanism and system components are only different according to actual needs, and different types of photovoltaic systems will be described in detail below.

2. Classification and introduction of photovoltaic systems

Generally, photovoltaic systems are divided into independent systems, grid-connected systems and hybrid systems. According to the application form, application scale and load type of the photovoltaic system, the photovoltaic power supply system can be divided into the following six types: small solar power supply system (Small DC); simple DC system (Simple DC system) DC); large solar power supply system (Large DC); AC, DC power supply system (AC/DC); grid-connected system (Utility Grid Connect); hybrid power supply system (Hybrid); grid-connected hybrid system.

Photovoltaic power generation is an electronic component technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key component of this technology is the solar cell. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell element, and then combined with components such as a power controller to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less restricted by geographical areas, because the sun shines on the earth; the photovoltaic system also has the advantages of safety and reliability, no noise, low pollution, no need to consume fuel and erect transmission lines, and can generate electricity and power locally, and the construction period is short.

Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into . Regardless of whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of three parts: solar panels (components), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical parts. Therefore, photovoltaic power generation equipment Extremely refined, reliable and stable, long life, easy installation and maintenance. In theory, photovoltaic power generation technology can be used in any occasion that requires power, ranging from spacecraft, down to household power, large to megawatt power stations, small to toys, photovoltaic power is everywhere. The most basic components of solar photovoltaic power generation are solar cells (sheets), including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film cells. At present, monocrystalline and polycrystalline batteries are used the most, and amorphous batteries are used in some small systems and auxiliary power sources for calculators.
