Speaking of energy storage products, you may have large power storage, industrial and commercial energy storage equipment in your mind, but in fact, with the upgrading of technology and user consumption and the refinement of energy utilization around the world, more and more energy storage products present home and portable.

As a small edition of a technology company with 18 years of lithium battery and energy storage research and development and production experience, we will talk about this topic by comparing the series of household energy storage products and portable energy storage products produced by the company and their characteristics.

First, household energy storage products

Household energy storage products refer to energy storage systems used in home user scenarios, usually combined with household photovoltaic systems to provide electrical energy for home users.

The installed scale of such products is usually above 10kWh level, and the single machine scale is much smaller than the generation side/grid side/industrial and commercial energy storage that is usually above the megawatt-hour level.

Saving electricity is an important driving force for users to allocate storage. Household energy storage products generally generate electricity during the day, but the peak of household users' electricity consumption is at night, and the time of power generation and electricity consumption do not match. Configuring energy storage can help users store more electricity during the day for use at night. On the other hand, in the case of different electricity prices at different times of the day and peak and valley prices, the energy storage system can be charged through the grid or self-use photovoltaic panels during the trough period, and discharged for load use during the peak period, so as to avoid electricity consumption from the grid during the peak period and effectively save electricity.

Household energy storage product systems are usually composed of battery packs, battery management systems (BMS), energy storage converters (PCS) and energy management systems (EMS), of which energy storage batteries and converters are the core links with high value.

From the perspective of product form, it is equivalent to the extension of large-capacity portable energy storage. By stacking products and modules to achieve capacity expansion; The positioning is also more flexible, which can meet the emergency needs of several kilowatt-hours of electricity, and can also be extended to the whole house backup power supply. Taking into account outdoor use attributes, such as outdoor activities, outdoor gardens, RV scenes, etc., can be achieved by mobile design with wheels or by moving a battery module.

The home-type photovoltaic energy storage system is composed of photovoltaic and off-grid system, energy storage inverter, battery and load. For villa families, a set of 5kW photovoltaic energy storage system can fully meet the daily energy consumption.

During the day, photovoltaic panels on the roof can provide all the electricity needs of the villa family, while powering new energy vehicles. When these basic applications are met, the remaining power goes into the energy storage battery to prepare for the energy demand at night and cloudy weather, ensuring the efficient operation of the entire home energy storage system.

If there is a sudden power outage, the home energy storage system can maintain the continuity of power supply and the response time is extremely short. The home energy storage system makes solar panel power generation more reliable, avoiding the shortcomings of electricity generation on rainy days, and is undoubtedly the best choice for villa backup power.

Affected by the world energy crisis, home storage systems are becoming more and more common, accepted and loved by everyone, and are pioneers in implementing sustainable development.

Especially in Europe and the United States, this household energy storage products are very popular, in recent years, in China, there are more and more families in response to the national "green energy" call, choose this form of energy storage.
Second, portable energy storage products

1. Application scenario of portable energy storage products
Road trips and outdoor camping have become popular ways to go out. In addition to traditional camping equipment, rice cookers, kettles, coffee makers, projectors, drones, photography equipment, mobile air conditioners, incubators and other small appliances have gradually become the standard equipment for "exquisite camping".

Camping heat drives the surrounding industry to heat up, and portable energy storage products are among the new categories that are erupting in growth.
This kind of products are mainly for outdoor lighting, emergency lighting, mobile stalls, mountain forest operations and other activities, used for mobile phone charging, LED lighting, aerial photography, AC fans, DC fans and other AC and DC equipment power supply, control circuit, inverter circuit and lithium battery integration, easy to carry, easy to use.
2. Advantages of portable energy storage products
Portable energy storage products include: more power; Richer interface; Easy to carry; Support charging multiple digital devices simultaneously; Support a variety of charging methods; Short charging time long battery life and so on.
3. Types of portable energy storage products
Portable energy storage products can be divided into two categories according to the power of a single machine: one is a small, lightweight device with a power of 0.5-3kwh; The other category is equipment with a power of 5kwh to 30kwh, which can mainly replace the previous market of oil-fired generators.

3.6kwh energy storage portable power station
In addition to advance charging, portable energy storage can also be used with solar panels, the output power of a single solar panel is between 60w and 400w, so that when the battery is exhausted, the use of photovoltaic energy storage is charged outdoors to form a small solar power generation system to achieve continuous off-grid power generation and extend the power supply life.

An energy storage power station with a huge capacity of 32kwh
At present, the 3.6kwh household portable energy storage power station and 32kwh industrial energy storage power station have been developed, which are respectively suitable for household and hotel, bank, hospital and other industrial scenarios, and have been fully introduced to the market, and have been sold to many countries in the world.
