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. The PrimeVOLT team will also assist customers in communicating with electrical technicians and Taipower over technical matters, in addition to offering flexible designs and production performance. These services are rarely offered by other agent vendors.

“As for the outlook of the future,” Ching-Ming Chuang states, “the overall device capacity of Taiwan’s market has shown a downward trend this year due to policy uncertainties. However, PrimeVOLT will continue to grow at an annual rate of more than 20%.

From face-to-face sales, to product tests and participation in the Energy Taiwan convention, PrimeVOLT has gained prestige and is well received by the industry. To embrace future business opportunities born from Taiwan’s goal of achieving 14GW ground type PV installation by  2025, PrimeVOLT is prepared to make use of the anti-moisture and anti-salt fog protection features of its products to not only meet local needs but also to provide real-time technical support to safeguard the energy transition and ensure power generation quality.

Taiwanese Manufacture and Service
PrimeVOLT Launches Multiple PV Inverters

News coverage: Energy Trend

In order to achieve an accumulated capacity goal of 20GW by 2025, Taiwan’s government is actively promoting photovoltaic installation to further development. PrimeVOLT, a subsidiary company of Asian Power Devices Incorporated, has been an avid supporter of such cause. PrimeVOLT took advantage of its local service network as well as qualified products that are entirely made and designed in Taiwan. At the 2019 Energy Taiwan trade show, multiple portfolios of brand new PV inverters were launched, providing all new solutions to solve existing challenges. The show booth was seen having an unprecedented turnout of visitors.

Debut of Lightweight and High Efficiency PV Inverters

Active in the development of the solar energy industry for years, in Energy Taiwan 2019, PrimeVOLT introduced numerous PV inverters to the market, including the four single-phase 3kW, 3.6kW, 5kW, and HV-5kW. Aside from a significant improvement in efficiency, they now pack 20% less bulk and weight compared with previous products.

Meanwhile, PrimeVOLT also launched three-phase PV inverter with larger capacity. Since the launch of 40kW PV inverter in 2018, 60kW and 75kW three-phase flagship products have been introduced to the market. These PV inverters come with four MPPTs and are capable of maximizing power generation in each one of the PV array, resulting in an overall increase of efficiency in power generation.

PrimeVOLT’s new 60kW and 75kW Three-Phase Flagship PV Inverters

Whether single-phase or three-phase PV inverters, PrimeVOLT’s products were all designed with uni-body aluminum die-casting housing which, in contrast with conventional PV inverters with welded modular steel housing that is susceptible to erosion and waterproof damage, is of one-piece seamless design. PrimeVOLT PV inverters not only have sturdy housing but alsoIP65 certification. The fact that all PrimeVOLT’s products were certified by IEC salt-spraying tests which means that they are able to maintain the optimal operating efficiency even in adverse conditions like hot, humid environments, beaches, or areas adjacent to a water body.

In compliance with Taiwan governmental policies, all PrimeVOLT PV inverters have certified by VPC (Voluntary Product Certification) from the Bureau of Standards, Metrology, and Inspection for the voluntary certification of the products. Additionally, PrimeVOLT has further enlarged PV inverter output capacity to make up for power losses when static VAR compensators are at work.

Normally, in trying to maintain stability of grid, all power generators must simultaneously supply both static and dynamic reactive power. The purpose of supplying static reactive power is to stabilize and maintain voltage during reactive power compensation so that the power system remains operational. However, reactive power compensation reduces power generation and incomes. PrimeVOLT General Manager, Chuang, Ching-Ming states: “To this end, PrimeVOLT has improved the designs of all products so that aside from meeting the requirement for reactive power control, sufficient power generation is achieved. In the case of the 40kW PV inverter, a total power output of 44.5 kVA can be achieved, even during the time of reactive power compensation. Such is guarantee that the actual power output can still be kept as maximum 40kW.”

The advantage of being a local company means the speediest and most complete service that’s available to customers.

For the future, PrimeVOLT will continue to bring new products to the market in alignment with future trends. There is a high likelihood of developing PV inverter with even larger capacity and a strategic positioning of the company in the large-scale, land-based solar power plant market. PrimeVOLT also plans to diversify sales by targeting the demand of PV inverter for various renewable energy sources and developing pertinent solutions.

With its cost-effective and reliable Taiwanese-made products, PrimeVOLT will offer locally oriented service to fulfil the needs of its customers.

The professional approach and customized service have garnered widespread praise in the industry.”

The Taiwan’s government is actively promoting solar energy development. According to the Ministry of Economic Affairs’ Green Energy Plan, the accumulated solar power capacity would be scheduled to reach 20GW by 2025. Idle watersides like beaches will be prime grounds for large-scale solar power plant development. Industrial power gobblers will be required to harvest a certain percentage of their power use from renewable energy sources. Power stations employing rooftop panels will also be in demand. In face of enormous market potential, PrimeVOLT’s entire PV inverter series offer excellent protection against humidity and salt-spraying. Being a 100% locally oriented company also allows PrimeVOLT to better serve the needs of local customers and provide immediate technical support to ensure great power output and reliability.

Recently, the Industrial Technology Research Institute of Taiwan (ITRI) hosted an energy forum to discuss applications of “Water-based solar power generation and the incorporation of solar power in fishery industry”, analyzing the latest core technology of solar power system construction in addition to successful implementations of water-based cases.

Vincent Fan, the Director for PrimeVOLT’s Business Division

PrimeVOLT was invited to share its success and experience in planning and installing inverters in the water-based projects. Vincent Fan, the Director of PrimeVOLT’s Business Division stated: “Both water-based and land-based implementations must take into account environmental conditions and assess the overall efficiency and return on investment over 20 years. The welded parts of inverters installed in the water-based cases are usually subject to corrosion, resulting in water seepage, which causes system malfunctions. For salt-water applications, salt resistance and anti-corrosion capabilities shall be taken into consideration for the inverter’s body case and its connectors.”

100% designed and manufactured in Taiwan, PrimeVOLT has for many years, devoted to the research and development of the PV inverter. The PrimeVOLT inverter features a unique aluminum die-casting case, a one-piece body and water-proof design, thereby preventing corrosion or water penetration from occurring in welded parts after long-term usage. Complemented by water-proof surface conditioning, anti-salt and anti-corrosion baking-varnish coating, the PV inverter series can maintain an IP 65 water-proof and dust-proof level and has passed IEC salt-fog tests (IEC 60068-2-52 Severity 5).

Interview with PrimeVOLT:Service and Localization Essential on the PV Market


Taiwan’s PV market has shown a lot of promising growth in recent years. In 2017, its total PV power output hit a record high 1.69 billion Kw/hour, while its total PV installation capacity exceeded 1 GW by the end of the year. This year, a growing number of vendors will begin to shift their focus towards long term operational efficiency and performance as the market becomes more mature. With the overall difference in PV technologies becoming less noticeable, more and more vendors will begin to direct their attention towards after-sales services and localization.

A manufacturer from Taiwan whose business emphasizes both service and localization is PrimeVOLT, a business group of Asian Power Devices (APD). At Energy Taiwan 2018, PrimeVOLT displayed its 40 kW three -phase grid-connection PV inverter which boasts 100% Taiwan design, localized production, and high cost-performance ratio. The product also features multiple certifications, high-efficiency after-sales services, and technological support, which impressed many visitors.

Creating a Solution for Ground-Mounted Projects via Design

Following the completion of its two-year PV power plan which focuses on rooftop solar panels, the Taiwanese government will start pushing for ground-mounted PV power plants to materialize its “nuclear-free homeland” vision by 2025. PrimeVOLT’s 40 kW three-phase grid-connection PV inverter is a new model for application in ground-mounted PV power systems, boasting excellent stability and performance, which is similar to its predecessor 30 kW three-phase grid-connection PV inverter.

Thanks to its special design, PrimeVolt’s PV inverter can be installed on tidal lands or salt flats, which are often sites for local PV power ground-mounted stations. The inverter features a unique aluminum die-casting case, a one-piece body, and water-proof design, preventing corrosion or water penetration, which are common in welded parts after long usage. With the usage of a water-proof membrane and anti-salt and -corrosion baking-varnish coating, the PV inverter can still maintain an IP 65 water- and dust-proof level after long years of usage and has passed the IEC salt-fog tests.

Services not limited to own products

PV power plant development can be very complicated, involving not only design, panel, and frame of the system, but also power allocation from the state-run Taiwan Power Company. These can all affect power output and reliability in the long run. In addition to the provision of the PV inverter, PrimeVolt can assist customers in the planning and design of their own PV power plants.

“Taking advantage of localization to meet customer demands which cannot be satisfied by others” is what has enabled PrimeVOLT to become a leading PV inverter supplier in Taiwan, points out PrimeVOLT general manager Zhuang Chin-min, who stresses the long term importance of services on the PV power device market

After-sales services critical for long-term performance

With the gradual maturity of the PV power market, warranty, timely after-sales services, and sufficient technological support have become key factors for customers in selecting suppliers, due to the inevitability of the malfunction or breaking down of PV inverters which are exposed to the environment for a long period. This is another edge of PrimeVOLT, thanks to its localization.

Due to its local advantage, PrimeVOLT offers on-site repair services guaranteed for completion within 48 hours, which often drops to 24 hours in the case of PV inverters. “In many cases, we found that the problem lies in parts other than the PV inverter,” notes Fan Ming-chung, the Director for PrimeVOLT’s business division. The situation has prompted PrimeVOLT to expand the coverage of their services to parts other than the PV inverter.

During Energy Taiwan 2018, it is evident that PrimeVOLT has established a trustworthy reputation on the local market because of the reliability and high cost-price ratio of its product, and its real-time local services. With four items having passed VPC (voluntary product certification) in early July, PrimeVOLT is expected to pass the certification for the entire series of models by the end of 2018. In the future, PrimeVOLT will put forth grid-connection PV inverters with even larger capacities, which will also be coupled with quality services.
