How Solar Inverters Efficiently Manage High-Temperature
One of the most significant ways heat affects solar inverters is through efficiency reduction. Inverters follow a temperature derating curve, meaning their efficiency decreases as
When temperatures rise, the efficiency of a solar inverter decreases. Semiconductor materials in the inverter's circuitry experience increased resistance as they heat up, leading to more energy being lost as heat rather than converted into electricity.
Read on while I explain how heat saps your inverter's efficiency—and your wallet. Anything electrical doesn't cope well with heat. Solar inverters detect when they're getting too hot and throttle back, converting less solar DC into AC electricity, which is a shame when you need that energy to run the air conditioning.
As the current flows, the heat builds up and is usually removed from the device using heat sinks, fans, or a combination thereof. Solar inverters convert DC to AC using a transformer and other components to deliver the final usable current to the load-connected appliances and devices.
Significant heat can still be generated in the inverter during this process, even in cold weather. Electronic devices have far greater operating efficiency at lower temperatures than higher ones, so manufacturers look to reduce and eliminate heat buildup.
