Solar photoelectric helps activate lands PrimeVOLT inverters become the driving force of carbon reduction

Heat waves are striking globally, and it is imperative to curb the speed of global warning with the use of renewable energy; how to implement the applications of renewable energy and Net Zero carbon reduction have become important issues that governments and enterprises around the world are now focusing on. Taiwan is on the Tropic of Cancer and has sufficient sunshine all year long, which makes it very suitable for solar photoelectricity development; however, it also often faces the challenge of difficult land acquisition. As a matter of fact, many lands in coastal areas of Taiwan are often abandoned due to subsidence or severe salt damages, which caused them to be geologically unfavorable for farming. The construction of solar farms not only can bring a ray of life to the revitalization of barren lands, neither will it affect the development of normal agriculture; the considerable carbon reduction effects that it can bring due to the renewable energy are also extremely meaningful nowadays when global warming is intensifying.

The Sen Ju Green Energy Solar Farm located at Fangyuan Township, Changhua County is a ground-based solar farm built on such barren lands. The capacity of the devices of this farm is 2MW, and they all use PrimeVOLT’s 60kW three phase on-grid PV inverters. The owner stated that Changhua County has sufficient sunlight, and according to the data from Taipower, the average daily power generation per 1 kW of solar power is as high as 3. 55KWH, which is the highest average power generation among all counties and cities in Taiwan. It is estimated that its investment payback period will be the shortest in all counties and cities in Taiwan; it is extremely economical. More importantly, the annual power generation of the farm is as high as 2. 6 million KWH. According to the statistics of Taipower, the average power usage per household for 2021 was 352KWH, which means that this farm can provide electricity for over 600 households for a year; it can even reduce carbon emission by approximately 1300 tons per year, which is the annual carbon intake of over 3 Daan Forest Park. Because of the construction of the solar energy system on the barren lands that are unfavorable for farming, its actual carbon reduction contribution to the global environment cannot be underestimated.

 

*Sen Ju Green Energy – Changhua Fangyuan solar farm fully adopts PrimeVOLT’s 60kW smart on-grid PV inverters

This farm is close to the Changhua Wanggong coastal area, where there are strong sea breeze and severe salt damages; the owner specifically chose PrimeVOLT 60kW string solar PV inverters that comply with IP66 waterproof and dust-proof standards and passed IEC 60068-2-52: 2017 severity 5 international salt spray tests. Its salt-proof design can adapt to the special geographical environment of high salt damage in the coastal areas, and fully exert the maximum performances of the inverters. In addition, PrimeVOLT 60kW three phase on-grid PV inverters are equipped with four sets of MPPT that can be flexibly configured according to the different terrains and orientations of the farm, converting the power generation of the solar module more efficiently. The PF 0. 9 real power output with no derating can improve the overall power generation revenue, and the AFCI arc detection function can detect arc anomalies in real-time, reducing the risk of fire for the farm.

That’s worth mentioning is that PrimeVOLT inverters are string type with the features of flexible configuration and easy construction/maintenance. The difficulty for its operation and maintenance is much lower than the more centralized inverters. Whenever there are malfunctions, it is easier to identify the failure point of string inverters; this improves the efficiency for operation/maintenance and saves the cost for maintenance manpower significantly. In addition, the entire series of PrimeVOLT inverter products all have built-in DC junction box functions, there is no need to purchase additional DC junction boxes; it can reduce the construction cost for the farm directly, and shorten the investment payback period of the solar farm, in which the AC/DC surge protector can provide comprehensive protection for the farm to improve the safety of the farm.

PrimeVOLT inverters have won the “Taiwan Excellent PV” award repeatedly from the Ministry of Economic Affairs with their outstanding and high-performance product qualities; higher power and energy-storage models will continually be launched in the future based on market trends and needs. PrimeVOLT will work hand in hand with its various large farm customers across Taiwan to implement energy transition and achieve the government’s goal of Net Zero carbon emission by 2050.

30% Growth in Inverter Shipments Catapults PrimeVOLT into 2nd Place

(Taipei) The results for PV inverter shipments in the first half of 2021 have now been released. Competition is heated up this year with PrimeVOLT, a major inverter marker, snapping at the heels of Delta, another Taiwanese company. Chinese and other imported inverter brands were left in the dust, catapulting PrimeVOLT into 2nd place in a fiercely competitive market.

Reference site – Eon-solar Energy Co., Ltd.

PrimeVOLT is a local PV inverter manufacturer and the company has set a goal of 30% growth each year. Despite the COVID-19 pandemic, customer delays and other variables this year, PrimeVOLT still managed to far exceed its goal of a 30% growth in shipment volumes in the first half of the year. While COVID-19, part shortages and rising part prices are set to bring new risks and challenges in the second half of the year, PrimeVOLT is still optimistic that its total shipments for the year will surpass its annual target.

A battle for supremacy is now taking place between string inverters and central inverters in the inverter market. Jimmy Chuang, General Manager of PrimeVOLT, states that while string inverters suffered from higher initial construction costs, central inverters have one fatal weakness: Any failure results in large-scale outages. Repairs are also difficult and may take anywhere from several weeks to two months to complete.

The development of solar power in Taiwan is now moving from roof-mounted systems to ground-based systems. Initially, some ground-based projects used the centralized model, but there has been a gradual shift to string inverters in line with international practice. PrimeVOLT is continuing to communicate with customers about the need to also look at material requirements, construction costs, future failure rates and operation & maintenance in addition to maximizing the power output of their system.

More and more projects are now turning away from central inverters to optimize overall generating performance and return on investment. Large, medium and small projects are now increasingly dominated by the string type. The full range of string inverter products offered by PrimeVOLT helped the company consolidate its position in the small and medium-sized market, making it the undisputed No. 1 in the rooftop market. Significant inroads have also been made in the large project market, giving PrimeVOLT a clear edge.

In the past, large projects may be enough to move a company several places up the market rankings, and vice versa. The increasing number of ground-based projects means that individual projects will have an even greater impact in the future. PrimeVOLT has been cultivating customers of all types over the years. Having accumulated up to 500 customers over the last decade, it does not rely on a single project site to keep up its numbers. The decision by many large ground-based projects to make PrimeVOLT their preferred supplier in recent years is of tremendous significance as well. (Yung-Chuan, Weng)

Equipped with String Detection and Easy to Maintain, PrimeVOLT Debuts its All New 75kW Inverters

The Bureau of Energy, MOEA plans to increase PV installation power production to 20GW production by 2025, signaling the importance of solar energy when it comes to energy generation transition. In alignment with the government’s green energy policy, PrimeVOLT, a local inverter manufacturer in Taiwan, introduced a series of inverter product lines applicable to different installation environments ranging from rooftop models, large-scale ground usage models, in addition to models adept for use in harsh salt flats. These products are not only equipped with their unique advantages but also offer localized real-time operation and maintenance services.

PV inverters are divided into two main categories: string inverters and central inverters. PrimeVOLT is a top manufacturer specializing in the production of string inverters, with its own 3~75 kW inverter series featuring excellent performance in terms of corrosion resistance and the ability to operate in harsh environments such as places of high humidity. Aside from being implemented in the Penghu archipelago for over 5 years; PrimeVOLT’s inverters have also been applied in several large-scale salt flats in the central and southern Taiwan, as well as numerous reservoir projects, proving time after time that PrimeVOLT inverters deliver exceptional performance.

For the medium to large scale solar energy sites, PrimeVOLT introduced upgraded 60kW and 75kW Three Phase On-Grid PV Inverters in early 2020. The new inverter sets have inherited the one-piece aluminum die-casting case of previous models, passed IEC salt-fog tests, and solved corrosion & water penetration issues for its welded parts (which was a common problem among conventional inverters). Furthermore, the new inverter sets achieve an IP66 dust & water rating, ensuring optimal heat dissipation and operation in high temperature humidity environments, salt flats, or water body project sites.

Features included in the new inverter sets that are worth mentioning include the string detection and monitoring, Wi-Fi connectivity, non-reliance on DC junction box. The new string inverters can directly connect to the machine and feature a built-in DC switch, a DC FUSE, and a lightning protector that can effectively help EPC manufacturers reduce the system construction costs.

The addition of string detection and monitoring can boost solar power plant maintenance and inspection. The advantage of string converters lies in enhanced modular designs, allowing for compact and light weight products. Each solar array row corresponds to one converter, minimizing impact caused by differences in a series connection and shade, etc. After string detection and monitoring functions have been installed, it assists maintenance personnel in system detection and problem determination if the module is affected by partial shade such as dirt, leaves or abnormal power generation issues occur. This reduces maintenance costs, improves efficiency, as well as the precision of power generation predictions and estimations.

The output voltage of PrimeVOLT 60kW three phase on-grid PV inverters is 380V, which can meet the voltage requirements of rooftop types and factory buildings. The 75kW three phase on-grid PV inverters meet the needs of the high-voltage power systems in parallel of medium and large-scale cases with an output voltage of 480V. PrimeVOLT General Manager Ching-Ming Chuang pointed out that 480V voltage complies with American standards, and the products are not only easily replaceable, but also offer high compatibility. For high-voltage power systems in parallel sites, it will help improve the overall efficiency of the project and reduce maintenance risks and costs.

Regarding the replacement 5-year converters, Ching-Ming Chuang commented on the numerous issues that appeared in the past two years, such as a major client hoping to replace special specification units, or a certain vendor being terminating its services in Taiwan leaving clients with no clear solutions.  To better meet the needs of the consumers in Taiwan, PrimeVOLT strives to deliver product designs with features that are easy to replace offer downward compatibility.

 

rimeVOLT is one of the few Taiwanese manufacturers in the market with design, research and development capabilities. It has localized real-time services to meet customer needs and can provide professional consultancy services to work alongside clients in finding the right solution. Ching-Ming Chuang explained that the solar power projects require a service life of up to 20 years, during which PrimeVOLT will assist its clients in assessing the convenience and cost of maintenance.
