According to the company, the Fronius String Control 250/30 DCD DF has been specifically developed to meet the requirements of central inverters. With a current carrying capacity of 250 A and maximum input voltage of 1,000 V, the Fronius string monitoring device is particularly suited for the monitoring of photovoltaic systems that use Fronius Agilo inverters. Up to 30 module strings can all be connected together on one DC main line.
If a problem such as shading, module failure or broken or chafed cabling occurs in one or more strings, the relevant monitoring system informs the operator immediately. Loss of yield is thus prevented.
