String Inverter Specialist Solis Prepares For a Bright Future

Solis has been working in the field of string inverters for 17 years now, a period during which the pure play string inverter firm has used its focus to deliver performance across markets and categories. In market after market, the firm has emerged among the market leaders, building on strong product quality and service. With global solar additions set to cross over 200 GW annually for a decade and more, and the strong use cases for string inverters in more and more situations, Solis finds itself on a strong growth path.

As the core component of any solar PV system, the inverter is one of the main contributing factors of system revenue.

Quality components directly determine inverter life

Reliability and service life of an inverter is closely related to the quality of its components. The use of high quality components directly effects the performance of the inverter. At its main Ningbo facility with 40 GW capacity, Solis maintains strong relationships with world-renowned component suppliers to ensure the stable supply of high-quality componentry and consistent product reliability. The centralised production centre ensures tight control over quality as well as the ability to withstand supply shocks with adequate inventory.

Design and testing are the key to reliability

Investment is made in stress testing equipment which simulates extreme temperatures, humidity, wind, sand, rain, and salt spray encountered by an inverter in outdoor environments. Testing in this way ensures the reliability of the inverter can be evaluated and improved for ongoing product optimization.

Adaptable to extreme temperatures

Variation in temperature will affect the efficient working of an inverter and can be caused by regional differences, day to night, seasonal change, etc. The internal components of the inverter itself will also cause temperature variation which can all effect the long-term safe & efficient operation of the inverter.

Solis product design considers the impact of temperature changes and adopts various measures such as single-board concentration, coating protection, and internal fan cooling to protect the inverter. Solis design engineers  verify the performance of the entire machine through thermal cycling, damp heat, humidity, freezing, powered Thermal Cycling, High temperature & rain tests to identify any defects in the inverter’s internal electronic components.

Excellent outdoor adaptability

Other factors brought about by external field exposure, such as UV, salt spray, humidity, sand and so on can affect inverter efficiency and life. Strong environmental adaptability is crucial to the reliable operation of the inverter. Solis-(100-125) K-5G series inverters have IP66 protection and C5 anti-corrosion, and have excellent outdoor adaptability.

All Solis new products are powered on and run for more than 180 days in an exclusive test area. The status of the inverter is monitored daily via SolisCloud, to observe the main parameters of its power generation and internal temperature.

Comprehensive product quality control

R&D – production – testing – sales – service. This is a complete vertically integrated product supply chain; another unique advantage of Solis. Comprehensive product quality control through the flow and exchange of information at each stage, effectively ensures the reliability of the inverter is guaranteed.

Solis has a world-class design team and a recently  expanded manufacturing facility with automated digitalized product lines. It has the capability to test the reliability of all its products in all environmental scenarios.
