How to select solar power station

As ordinary users of solar power stations, the manufacturers of solar power stations are not the focus of ordinary users. They are more concerned about the quality, price, and service of solar power stations. However, as a wholesaler and seller of solar power stations, it is very important to choose a suitable solar power station manufacturer, as this directly affects the business and interests of the seller. How to choose a suitable maker (or supplier) for solar power stations? It is best to have knowledge of the solar power station manufacturer's information in the following areas.

How to select the shell of solar power station

The shape and color of solar power station

There are a wide variety of styles for solar power stations, including cylindrical, rectangular, and irregular shapes. There are simple designs and complex designs. In terms of color selection, black is the most common, as well as gray white, orange, green, blue, and red. Generally, solar power station manufacturing factory produces several samples in different colors for buyers to choose from. Of course, buyers can also choose their own colors according to their own needs, such as military green and navy blue for solar power stations used in the military.

Materials for solar power stations

In most cases, the solar power stations we see are made of ABS plastic through injection molding machines. ABS plastic is divided into many fire resistance grades, and the ABS material commonly used to make the shell of solar power stations is ordinary plastic with a fire resistance grade of HB. ABS fireproof materials are classified into HB, V2, V1, V0, 5VB, and 5VA levels based on their flame retardant properties, with HB level being the primary and 5VA level being the highest. These grades are classified according to the UL-94 flame retardant plastic standard. To produce flame-retardant ABS materials, flame retardants need to be added to ABS plastic to achieve flame retardant effects. Therefore, the higher the flame retardant level of ABS material, the higher its cost. Flame retardant ABS materials are widely used in various fields, including automobiles, construction, household

appliances, and office supplies. With the advancement of technology and the improvement of quality of life, people's demand for fire-resistant and flame-retardant materials is constantly increasing. Therefore, some solar power station brand merchants with high quality requirements will use different levels of ABS fire-resistant plastic according to their needs. Of course, in addition to using ABS material, some solar power station shells also use aluminum alloy shells or sheet metal casings. Compared with ABS material, aluminum alloy shells are lighter but more expensive; Sheet metal shells are stronger than ABS plastic shells, but more bulky. Generally, large household energy storage systems and inverters will choose aluminum alloy shells or sheet metal shells.

How to select the function of solar power station

Basic functions of solar power station

The main function of a solar power station is to provide emergency electricity. For example, during outdoor travel, self driving trips, or power outages, electronic devices such as mobile phones, digital cameras, and drones that we carry with us need to be charged. They can even be used for outdoor water boiling, cooking, lighting, cooling fans, mini refrigerators, etc. Solar power stations are different from the power banks we have purchased before. Although they are both designed to meet the emergency power needs of users, solar power stations have more functions and larger battery capacity than power banks. In addition, power banks generally only provide weak voltage (generally within 3.2V) DC current power supply through USB and Type-C methods, while solar power stations not only have the functions of power banks, but also have DC output and AC output. The output voltage includes both 220V and 110V output voltages.

the lithium battery, it requires the lithium battery test report, MSDS report (Material Safety Date Sheet Report), UN38.3 Test Report, and By Sea Identification and Classification Report for Transport of Goods (or Identification and Classification Report for Air Transport of Goods); If the energy storage battery of the solar power station is lead-acid battery, it requires the lead-acid battery test report, MSDS report (Material Safety Date Sheet Report), and By Sea Identification and Classification Report for Transport of Goods for the lead-acid battery, but not for Air Transport of Goods because lead-acid batteries are prohibited from being transported by air.

Upgrade functions of solar power station

In addition to providing backup power, solar power stations also have many upgraded functions. For example, many solar power stations on the market have added many new technologies to the power station for the convenience of users, such as providing wireless charging function, fast power supply function for the power station, emergency start function for household cars, external solar panel charging function, etc. Some solar power stations have also added Uninterruptible Power Supply (UPS) function to enable users to continue off grid power consumption. This can provide stable and uninterrupted power supply for outdoor camping or long-term power outages, so users do not have to worry about insufficient stored electricity in the power station.

TUV certification; Electrical appliances sold in North America require UL or CSA certification; Electrical appliances sold in Japan require PSE certification; Electrical appliances sold in Korea require KC certification; Electrical appliances sold in Switzerland require SEV certification; Electrical appliances sold in Australia require SAA certification; Electrical appliances sold in Brazil require BSI certification; Electrical appliances sold in China need to obtain CCC certification... In addition to the certification requirements of different countries mentioned above, many countries and regions have certain environmental requirements for the sale of electrical appliances. For example, many countries require electrical appliances to comply with mandatory environmental standards such as Reach, RoHS, and FCC.

So, in principle, the portable power station needs to obtain the certification described above when transported from one country to another, whether by land, sea, or air.

Many different kinds of solar power stations

How to select the power of solar power station

“If I want to purchase a solar power station for personal use, how many watts of power do I need to choose?” It's best to choose a solar power station with the appropriate power based on the appliances you use. If you only use it for emergency charging, lighting, electric fans and other low-power appliances, then you may only need to purchase a solar power station with a power of less than 300 watts. If you also need to use the solar power station to power medium and large power appliances such as kettles, Coffee-machine and rice cookers, it is best to purchase a solar power station with a power of over 1000 watts. If you were a wholesaler or retail trader of solar power stations, what wattage would you need to choose for the solar power stations? Because wholesalers or retailers purchase solar power stations primarily for distribution and retail purposes, solar power station sellers need to match and sell their products based on market demand, local market consumption levels, their own financial strength,

and other market information. If the main sales area of the seller belongs to wealthy residential streets or high-end commercial centers, it is necessary to purchase more high-power solar power stations. If the seller mainly sells power stations to emergency electricity buyers, choosing low-power solar power stations can meet the needs of users. If the seller is not particularly clear about the usage and needs of the users in their sales area, it is best to match the products at a ratio of 60%: 30%: 10%. Low-power power stations should be purchased at a ratio of 60%, medium-power power stations at a ratio of 30%, and high-power power stations at a ratio of 10%. This way, the product matching will be more ideal. Of course, this is just our past sales experience with solar power stations by our purchasers.

How to select batteries for solar power stations

At present, solar power stations mainly use lead-acid batteries, ternary (Ni, Co, Mn or Ni, Co, AI) lithium batteries, and lithium iron phosphate batteries (Lifepo4). Due to the different characteristics of the three types of batteries, there are also many choices, but currently the most popular solar power station on the market is still made of lithium iron phosphate batteries. Solar power stations made from lead-acid batteries are currently popular in Southeast Asia, Africa, South America, and Eastern Europe due to their low cost; Due to the high activity of its constituent elements, ternary lithium batteries are increasingly being replaced by solar power stations manufactured from lithium iron phosphate batteries（Lifepo4）. Therefore, the selection of what type of battery to use for solar power stations needs to be based on the local market. If it is mainly sold to developed countries, it is best to choose solar power stations made of lithium iron phosphate batteries. If it is sold to

countries with medium consumption levels, different types of solar power stations can be matched according to the local consumer situation. If it is sold to developing countries, it is best to mainly sell solar power stations made of lead-acid batteries.

How to select the battery capacity for solar power station

At present, many manufacturers prefer to produce solar power stations with different capacities using the same appearance, which makes it difficult for buyers to judge the power and battery capacity of the solar power station from its appearance. Moreover, most businesses label their products according to the writing standards of electrical appliances, only indicating the power on the exterior and outer box of solar power stations, and rarely indicating the capacity of the power station. Therefore, it is difficult for buyers to intuitively distinguish the specifications of the product. Even sellers of solar power stations can easily confuse the capacity of the product without learning about the knowledge of battery capacity differentiation. The prices of solar power stations with different battery capacities vary greatly, which makes it easy to ship the wrong goods and cause losses to buyers. Therefore, before purchasing solar power stations, buyers must first consult the

shop owner or salesperson, especially through online stores, and should first understand with customer service personnel, otherwise it is easy to mistake power for batteries. Capacity, As a result, I purchased a power station that did not meet my requirements. How to choose the capacity of a solar power station? The most intuitive way is to distinguish the battery capacity by the content of the specification column on the product manual or outer packaging. Another way is to distinguish the battery capacity by the weight of the solar power station, because the weight of the product will vary greatly depending on the battery capacity.

How to select a manufacturer for solar power stations

As ordinary users of solar power stations, the manufacturers of solar power stations are not the focus of ordinary users. They are more concerned about the quality, price, and service of solar power stations. However, as a wholesaler and retailer trader of solar power stations, it is very important to choose a suitable solar power station manufacturer, as this directly affects the business and interests of the seller. How do you choose a suitable maker (factory) for solar power stations? It is best to have knowledge of the manufacturer's information in the following areas.

how to porduct a solar power station

Qualifications and strengths of the maker

Solar power station manufacturers in China have obtained specialized production and business licenses, and the registered capital of large solar power station production factories is generally not less than RMB 5 million to demonstrate their factory strength; Manufacturers have independent factories, complete production equipment, clean production workshops, mature production lines, and standardized warehouses. They even have trucks specifically designed to deliver goods to customers' homes. Moreover, many manufacturers have obtained ISO9001 quality management system certification and comply with 6S production management standards. The skilled production workers for medium to large solar power stations will exceed 100 or even more. Therefore, choosing a production factory that meets these characteristics will be more reliable.

Certification of the solar power station

certifications for solar power stations

Solar power stations are electrical appliances that also contain batteries, making them hazardous chemicals. Therefore, solar power stations need to obtain MSDS reports and UN38.3 hazardous chemical transportation reports that have been tested by independent certification agencies during transportation. If sea transportation is required, a hazardous chemical sea transportation report must also be obtained. If air transportation is required, a hazardous chemical air transportation report must also be obtained. In addition, as a type of electrical appliance, solar power stations must comply with the requirements of the International Electrotechnical Commission (IEC) and the certification requirements of the selling country for electrical appliances. For example, electrical appliances sold in the European Union need to pass CE certification, electrical appliances sold in China need to pass CCC certification, electrical appliances sold in the United States need to pass

UL certification, electrical appliances sold in Japan need to pass PSE certification, electrical appliances sold in Korea need to pass KC certification, electrical appliances sold in the United Kingdom need to pass TUV certification, electrical appliances sold in Australia need to pass SAA certification, electrical appliances sold in Brazil need to pass BSI certification, electrical appliances sold in Thailand need to pass TISI certification, and there are many more. Of course, it would be even better if solar power station manufacturers have export qualifications.

After-sales service terms of solar power station suppliers

As a responsible manufacturer, we will establish a complete after-sales service system to provide after-sales service for buyers and consumers, provide timely feedback on after-sales consultation information from customers and consumers, and offer specific solutions. Excellent solar power station manufacturers are also confident in the quality of their products produced in their factories, providing three guarantee services for their products (free return and exchange period, after-sales terms, and quality terms), managing the entire after-sales process of their products, providing after-sales support for solar power station buyers, assisting buyers in expanding their markets, and promoting the sales of solar power stations by sellers. In addition, manufacturers with export experience often send many solar power stations to the world, and they are very familiar with global logistics routes. They can even assist us in customs declaration and transportation of goods, greatly saving us time and transportation costs.

Technical strength of solar power station maker

For sellers who are new to the solar power station industry, the most direct way to assess the technical strength of the suppliers we are negotiating cooperation with is to review whether the supplier's product line is complete, whether the product specifications are rich, and whether the design ideas of various solar power stations are consistent. Due to weak technical capabilities, factories do not have the ability to develop a series of products. They often only sell a certain specialty product, and there are also some solar power station intermediaries who piece together different specifications of solar power stations from many companies to form their own product series. However, these series of products will have significant differences in appearance, design concepts, and functions. As long as we are careful, we can easily identify the differences between different power stations. Because products designed by different companies will have significant differences in appearance, functionality, and the product certifications, intellectual property, and patents obtained will also vary.

Production experience of solar generator factories

As a mature production factory, we have been established or engaged in the new energy industry for many years, with many years of production experience accumulation. We have many skilled and stable production workers, and the product categories are also very complete. Only in this way，we can ensure timely delivery of orders and meet the needs of different buyers. Only skilled production workers can produce high-quality solar power station products. Therefore, in order to ensure the stability of product quality, timely delivery, and after-sales guarantee, it is best to choose a mature factory with many years of production experience for cooperation. There are many inexperienced buyers who only pursue affordable product prices, but easily overlook other factors, resulting in unnecessary trouble and losses, such as lack of inspection of the factory's relevant qualifications, products not obtaining all the certifications required for export, products using batteries that do not meet customs requirements, or products with packaging that does not meet export packaging requirements

How much of the solar power station?

The supply price of solar power stations is composed of many factors: 1. The determining factor of product price is cost. Generally, large manufacturers have a larger procurement scale, and due to economies of scale and integration of the industry chain, their procurement costs may be lower than those of small factories. 2. Mature and experienced manufacturers have higher technical and management costs due to their strong technical R&D personnel and management teams. 3. Due to the fact that the production workers of mature manufacturers are skilled technical workers, their production efficiency is higher, resulting in lower production costs. 4. Large solar power station production factories will invest a lot of testing equipment, research and development equipment, and production equipment in order to improve product quality, with a high investment in fixed assets. 5. Large factories invest more funds and factory owners hope to obtain richer profits, so they will also price their

products higher. Taking into account the above factors, the supply price of mature solar power station manufacturers will be about 20% higher. Of course, our purchasing price also requires our procurement personnel to negotiate with suppliers in order to obtain the most affordable price.

Market support provided by the manufacturer

An excellent solar power station generally has these characteristics: the product must be of good quality and affordable; It must have gained widespread recognition from consumers; The sales volume of the product is very high; There will be many distributors selling this product simultaneously in the same market; The quality of the product has been praised by users. So, if it is an excellent solar power station manufacturer, they must find a way to showcase and sell their products on all offline channels and e-commerce platforms. Many sellers will participate in the promotion and sales of the products, so that the products can gain widespread publicity and awareness, thereby achieving the goal of extensive market promotion. Therefore, when we cannot know whether a solar power station product has been widely promoted by the manufacturer, we only need to conduct research on various well-known online sales platforms to know the market promotion strength of this product.
