How to choose the photovoltaic inverter heat sink ?

Industry users are paying attention to the overall performance of the photovoltaic inverter, not just focus on their conversion efficiency, the largest dc voltage, ac output power, protection grade, such as heat dissipation problem of photovoltaic inverter also need us to pay special attention to, choose a high performance inverter heat sink is very necessary, because it will directly affect the inverter heat dissipation performance indicators.

Various components in the photovoltaic inverter have rated operating temperature. If the photovoltaic inverter  heat sink selected by the inverter has poor heat dissipation performance, when the inverter continues to work, the heat generated by the components inside has been collecting in the cavity, and its temperature will become higher and higher. High temperature will reduce the performance and life of components, the machine is prone to failure.

When the inverter works, it generates heat, and the power loss is inevitable. For example, for an inverter of 5kW, the system heat loss is about 75-125w, which affects the power generation. To solve the heat dissipation problem of inverter, it is best to cooperate with heat sink manufacturers to customize the inverter heat sink. After the heat sink manufacturers optimize, the heat dissipation loss can be reduced.
