Do you know what thermal material the micro inverter uses?

This type of thermal interface material is often used in micro-inverters: thermally conductive potting silicone, thermally conductive gasket, thermally conductive gel, to achieve heat conduction and heat dissipation, and at the same time, it is sealed and waterproof, and it is convenient for repair. The following example: Hemai Solar Micro Inverter MI-700 (the inverter body is about 24.5cm long, 171.55mm wide, 27.9mm thick, and the net weight is about 2535g), with 700W output power, waterproof design, and an all-aluminum casing , and the aluminum alloy backplane is used to enhance heat dissipation, and the interior is filled with elastic black heat-conducting potting silicone, which dissipates heat for the heating element and acts as a buffer. On the back of the inverter PCBA module, a white thermal pad is pasted on the position corresponding to the power device, and the shell is used for heat dissipation.

Other micro-inverters generally adopt the glue-filling mode, such as the ENPHASE ENERGY inverter whose model is IQ8X-BAT-US.

The photovoltaic inverter is the heart of the solar photovoltaic power generation system. It converts the direct current generated by the photovoltaic power generation system into the alternating current required for life, and its conversion efficiency directly affects the power generation efficiency of the photovoltaic system. Photovoltaic inverters can be divided into centralized, string, modular and micro inverters according to the technical route and power level. Among them, micro-inverters are mainly used in distributed scenarios such as households and small industrial and commercial applications due to the relatively low power level of a single inverter and high safety factor. It is estimated that the micro-inverse market size will be 86.4 billion yuan in 2025, and the five-year CAGR will be 80%. At that time, the global photovoltaic installed capacity reached 600GW, of which the distributed proportion increased steadily, reaching 48%. It is estimated that the demand for micro-inverters will reach 86.4GW, and the global micro-inverse market space is expected to reach 86.4 billion yuan, and the micro-inverter market will usher in rapid growth.
