Products - String Box 1000V
The FIMER string boxes, SBC series, are intelligent control boxes (SMART) which allow the measurement of the current of each input PV string from the solar generator and allow the creation of the parallel output of all the strings of PV modules connected to them.
These high-performance devices implement the current measurement using Hall effect transducers and ensure an accurate localization of the malfunction of the PV field minimizing the production downtime and facilitating the timely and targeted intervention of Service. Each string box is equipped with protections against overvoltage implemented by SPD varistors, the switch in input is implemented by the fuse holders and in output by a switch; these devices allow to isolate the single sub-field PV or the individual strings from the solar generator, allowing operators to work safely. Through these advanced technology products you can also manage the complete control and monitoring of the PV field. The monitoring of the unbalance of currents (miss-matching) is built and available within the control logic of our inverters. Thanks to the string box FIMER, SBC series, is possible to control the solar installation, using the INTEGRATED Modbus RTU protocol, and in this way it’s compatible with the most diffused communication systems on the market. Flexibility is first and foremost.
