Technology

Active Cooling

Active cooling technology relies on one or more fans, which not only avoid hot spots, but also regulate the air circulation inside the inverter, thus keeping the temperature of the power electronics low. This has a positive effect on the service life of the devices, optimises yields and reduces costs. At Fronius, active cooling is supplied as standard in all devices.

Dynamic Peak Manager

The Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behaviour when searching for the optimal operating point. Its special feature is that the Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global Maximum Power Point (GMPP), even in partial shade.
