In operation, the PV SMART boxes score with their maintenance-free operation, even under extreme temperature fluctuations. “Significantly decreased operating costs and consistently high performance lead to improved profitability of the PV systems,” emphasises Weidmüller Product Manager Juan Francisco Martínez. “The intelligent functions of the PV SMART combiner boxes equip EPC and O&M companies for future market trends.” Detailed requirements of customers were also taken into consideration during development. An example of this is the user-friendly removal of fuses.
The combiner boxes are developed and manufactured in accordance with IEC 61439-2 and are available for 1,000 V and 1,500 V applications. Weidmüller’s stringent laboratory tests ensure that the boxes have a long service life under all operating conditions. Monitoring each individual PV string provides additional assurance for ongoing operation.
