Technical FAQs 4

Can solar inverters be cooled?

Solar inverters can be cooled in one of two ways: by using a passive cooling system or through active cooling. Passive or natural cooling means that the inverter’s cooling fin dissipates heat without the need for a fan. This lack of air circulation leads to hotspots of warm air, which reduce the lifespan of the solar inverter.

How does solar inverter cooling work?

In order to keep the heat low, the inverter will stop generating power or reduce the amount of power it generates by “derating” as it passes programmed temperature milestones. Solar inverters can be cooled in one of two ways: by using a passive cooling system or through active cooling.

What is passive cooling in a solar inverter?

Passive or natural cooling means that the inverter’s cooling fin dissipates heat without the need for a fan. This lack of air circulation leads to hotspots of warm air, which reduce the lifespan of the solar inverter. The second alternative to passive cooling is to utilise active cooling.

What is a solar inverter cooling fan?

Solar inverter cooling fans are found throughout the inverter in specific places to maintain effective component cooling. In general, the bigger the solar inverter system, the more (and bigger) cooling fans you’ll find. Solar inverter cooling fans are mechanical by nature and subject to wear and tear.
