Abstract: Ginlong introduced the break-through 4G Solis inverter product line
On April 12, 2018, the “Solis Brand New 4G Inverter”product launch conference went successfully at The Park Hotel Hyderabad in India. The significant technical breakthrough of Solis 4G Inverter based on the new 4th generation of Inverter platform in aspects of performance, security and grid-friendliness was perfectly demonstrated during the event.
The conference has attracted great attention from PV industry insiders. Together with nearly 120+customers and EQ news media groups from solar industry and internet portals such as EQ attended this new product release conference. The industrial insiders and media groups witnessed this major technical breakthrough and showed their interest and anticipation for the technology innovation.
At 9:30 am, the new product launch conference kicked off by Mr. Heng Zhang.
Solis was also honored to have all the attendees from solar industry present at the conference as well.
Solis 4G Inverter Unveiling Ceremony was held during the conference at 10:30 am and 2KW 4G solar inverter unveiled jointly. The media reporters and conference audiences present witnessed this exciting moment with great applause.
During the conference, customers from Mexico, US and Sweden highly praised Solis via videos for their quality products and attentive service ever delivered, and at the same time, expressed their anticipation to Solis new 4G inverters.
Solis R&D team has dedicated over 1000 days and nights to create this brand new 4G inverter with better performance, better safety and better user-friendliness. They made great efforts and brought out this new product with their sincerity, and won this great achievement which is well deserved.
Following a brief introductory , Solis 4g inverter video played , Mr. Heng zhang introduced the new 4G product , In great detail question answer session with audience was held .“The new 4G string inverters have unique advantages compared to those conventional inverters in the market, Mr. Idrish Khan said he then further explained these strengths as following:
The first strength is its performance improvement. 4G represents the 4th generation. The 4G inverter uses brand new 4G inverter technology platform the new product can have a maximum of 2 MPPT tracking; and can be extended to 4 MPPT. Multi-channel MPPT technology is one of the key factors in increasing electricity output. The common single-phase inverters generally can only achieve a maximum of 2 MPPT. The new product uses the latest 5th generation of German Infineon IGBT chip technology, whereas others generally use the 3rd generation product. The 5th generation of IGBT can increase the efficiency by 0.5-0.8% compared with the former generation. The new US TI2806 series DSP chip technology was adopted, and its CPU processing speed and PWM resolution have increased 50% over the generally-adopted 2803 series. The switching frequency of the inverter exceeds 30kHZ, whereas the common inverters are usually at 20kHZ or below, and this in turn, will greatly reduce the inductance loss and at the same time results in lower temperature increase. As all know, with the ambient temperature lower for every 10 degrees, the electronic components’ lifespan can be doubled each time. The noise frequency range that can be captured by human being is below 20 kHz, and the 4G product breakthrough the switching frequency of 30 kHz, and hence brings the users a real pure mute mode. The innovated main circuit board design greatly improves EMC+EMS performances of the inverter as well.
The second strength is its safety improvement. The product applies hardware dead zone technology and achieves double safety guarantee. Customers can choice to use AFCI anti arc device. Previously there was almost no method to automatically prevent the fire in case the PV system caught a fire. With this technical application, Solis 4G inverter can promptly detect the fire on the rooftop. Even if the components and wire terminals produce arc ignition due to poor contact, the inverter can automatically cut off the circuit within the shortest period of time to put off arc ignition. It can escape the fire by 99%.
The third strength is its grid-friendliness improvement. Solis uses a built-in EPM module to realize the intelligent scheduling of the grid. In other words, the grid can realize the intelligent control of the 4G inverter through EPM protocols, and achieve optimal grid dispatch under large scale distributed system grid access conditions. The new active voltage stabilization technology stabilizes the local grid voltage through no-power compensation. At present, the grids in rural areas are generally not in good condition, and the inverter access will cause voltage fluctuation of the grid. The common method used by a conventional inverter is to loosen up its voltage range to passively adapt to this situation. Solis 4G inverter, on the other hand, sends inductive or capacitive reactive power to proactively compensate for it, in this way, it can flat the grid fluctuations and stabilize the local grid voltage. This technology is currently widely adopted in large-scale power plants in rural areas with weak grid condition, and the improvement is very obvious.
Solis is willing to take the responsibility on behalf of the industry, bringing a high-end, independently innovated brand new inverter technology platform. Its behavior has won high praises and good wishes for further developments and achievements from the conference attendees.
