Solis to Launch its 255K Solar Inverter on 22 July 2020
The new inverter can reduce LCOE by more than 3.5%.
2020 is the year when the photovoltaic industry moves from subsidy to parity, and also the year of great technological change. Since the beginning of the year, at least seven companies have released new PV modules, with power moving from 500W to 600W+.
The renewable industry in India is witnessing aggressive bidding, so the current trend and requirement for higher capacity PV modules and advanced technology string inverters to maximize plant generation and achieve a faster return on investments (ROI) is likely to increase at pace.
The new trend of technology adaptation tends to be either in the PV module or solar inverter segment, which helps PV projects achieve better results. They have many other advantages in terms of ease of design, project installation, and ease of operation and maintenance, which is also an added advantage with string inverter technologies.
The advancement of PV module technology further promotes the transformation of system design and inverter technology and realizes the reduction of LCOE (levelized cost of electricity). To promote the reduction of LCOE, PV power plant designs present three obvious new trends:
- Trend 1: High DC/AC ratio becoming the mainstream
- Trend 2: The adaptation of bi-facial modules usage exceeds 50% globally
- Trend 3: High watt peak power PV modules are widely used
It is exciting to see that new technologies promote the cost reduction and efficiency increase of the photovoltaic industry, but at the same time, there are numerous other challenges that project developers or IPP companies need to deal with. Taking into consideration all these requirements and understanding the market demand, Ginlong Technologies has designed and developed a new inverter for PV power plants: Solis-255K-EHV (“Solis 255K”) Ultra-High-Power Inverter.
Solis 255K will be launched in India on July 22, 2020, between 2:30-4:15 pm.
Leading PV experts- Shri Pranav Mehta, Chairman of National Solar Energy Federation of India, will share his insights on the challenges and opportunities of the Indian solar market and how ISA is supporting the global solar industry and the forecast for 2021. Mr. Parag Sharma, CEO of O2 Power Private Limited, will also be joining our new product launch as guest speaker.

1. 53 MPPTs design per MW supports 200% DC/AC ratio
A high DC/AC ratio can further improve the power curve to optimize a PV plant’s comprehensive income. Some inverters cannot achieve a high DC/AC ratio due to the limitation of inputs. Solis 255K, with rated power up to 255 kW, 12 MPPTs, and 24 string inputs and 53 MPPTs design per MW, meets the requirements of large-scale power plants and overall efficiency breaks through 99%. For the same 6.3 MW block design, Solis 255K inverter solution can reduce LCOE by more than 3.5%.
2. Supports 25A short-circuit current which allows compatibility with bifacial modules
In addition to the high DC/AC ratio, high-power, bifacial modules can also effectively reduce the LCOE, and are becoming popular and more widely used.
India introduced a solar power plant policy ten years ago, and now after a decade, India’s solar PV industry has grown rapidly with several solar parks and large rooftop projects.
The Government of India has set the target of 100 GW by 2022 and is also promoting the “Make in India” concept, due to which we have seen great increases in local manufacturing facilities for producing finished PV modules in India. A few companies have PV cell production facilities in India, and 70% of PV modules are imported from overseas to achieve the annual targets.
Compared with traditional PV modules, the short circuit current and nominal current of the new large silicon wafer modules can be improved by more than 35%. For bifacial modules, the power gain on the backside mainly comes from the current increase, by nearly 10%, with the highest close to 15Amp.
At present, the DC input capacity of mainstream string inverters in the market is about 12-13A, which can no longer meet the requirements of high-power bifacial modules. Aiming at the trend of high-power bifacial modules, Solis 255K upgrades, and improves the hardware and software. Solis 255K DC input current and short-circuit current of each string can reach up to 15A and 25A, which perfectly adapts to high-power bifacial modules.
3. Adoption of high-power bifacial modules, lower LCOE
Solis 255K is the highest power string inverter available today, which perfectly matches the high-power modules to help the system owner achieve a lower LCOE.
Compared with low-power modules, high-power modules can effectively reduce the cost of DC cables, inverter foundation, land, and labor. For 255kW inverter + high power modules, the cost savings on the AC side lead to a nearly 7% reduction in the LCOE.
4. Expandable Storage Interface
Solis 255K has an expandable storage interface to accommodate peak saving and provide electricity to support the load and reduce the overall power supply cost. Energy storage terminals are integrated, which can support up to 125kW charge and discharge power. This inverter facilitates the expansion of energy storage at a later stage, without changing any existing plant design. It can easily solve the requirement of whether the power plant needs energy storage now or in the future. Solis 255K has been designed to deal with current market demand, and it can easily adapt to become a storage inverter if storage is required in the future. The system can transform into an energy storage plant.
5. One-stop solution for developers
To match with the new trend of market technology changes, Solis 255K, with more professional technical methods adopted, provides a one-stop solution for all developers and IPP companies. Solis 255K has been designed to work with a high DC/AC ratio and with high current carrying capabilities, which are major concerns when using high-power bifacial modules.
Focus on quality and continuous innovation is the core strength of Ginlong Technologies. The design and manufacturing of Solis 255K will lead to a Green Energy Revolution.
