Highly-developed converter/inverters ensure operating cycles of modern solar energy plants free from interferences. For this, a powerful cooling system is used which also meets the increasing performance outputs. Environmental effects such as dust and soiling or temperatures above 40 °C can reduce the cooling output of conventional air-cooled inverters. Heat discharge becomes more difficult and results in unnecessary temperature increases within the inverter and thus decreases efficiency dramatically. VENSYS water cooling systems allow for a constant and low-maintenance operation of the inverter and ensure a high energy output, a long lifetime cycle and are safe to operate.
