As a power electronic device, the mainfunction of photovoltaic inverters is to convert the DC generated byphotovoltaic modules into AC. There are thousands of electronic componentsinside, and most of them are heat source devices, so the heat dissipation has asignificant impact on the lifespan of the inverter.

In order to lower the temperature ofcomponents in the inverter faster and ensure a longer service life of thecomponents, it’s sensible to design an integral shell that is in close contactwith the radiator, making the shell an important component of the system's heatdissipation. The improvement of heat dissipation performance and high shelltemperature are normal phenomena in the operation of the inverter.

There will be a sense of warmth when theapparent temperature of the human body is about 36 degrees; a burning sensationaround 45 degrees; burning pain when long term contact at around 50 degrees;burns when long term contact at 60 degrees can cause.

Due to the need for heat dissipation andthe special nature of the working environment (outdoor direct sunlight) of theinverter, safety standards stipulate that the temperature of the inverter shellcannot exceed 70 degrees. When the external environment temperature is 40 degreesin summer, the shell temperature is generally between 55 degrees and 60degrees. Therefore, when people touch the inverter shell, they will feel hot,but it will not cause burns.

MULTIFIT was founded in 2009 and has beendedicated to the new energy industry since then and focusing on providingcustomers with world-class photovoltaic power station solutions. We not only havea technologically advanced and experienced R & D team, but also have a fastresponse and knowledgeable sales team, dedicating to providing customers withprofessional technical support and a smooth and satisfied shopping experience.

Since the establishment, MULTIFIT hasalways been committed to the design, research and development, production, andmanufacturing of inverters, producing a batch of inverters with good heatdissipation effect, strong load capacity, and high conversion efficiency. Sofar, our inverters have been sold well in over 50 countries and regions.

Our inverter has a shell made of aluminumalloy and have an excellent heat dissipation; also has a built-in small fan, whichwill automatically run when the temperature exceeds 30 degrees. These dualprotection help to faster reduce the temperature of internal components of theinverter and maintaining their longer service life. In addition, our inverteralso features intelligent battery management, AVR function, energy-saving mode,communication technology, power frequency transformer technology design, and afast conversion time of less than 10 milliseconds. Therefore, even in harshworking environments and unstable power conditions, it can still operate stablyand efficiently.

In the future, MULTIFIT will continue toinvest in design and development, continuously update our products, adhere tothe goal of Sunshine for you ,Multifit toall, and create more high-quality products!
