Fitted between the solar modules and the inverter, the generator combiner boxes bring together the electricity that has been generated. Weidmüller has developed many standard configurations of generator combiner boxes based upon recurring customer requirements. These provide an optimal connection system, and also protection and monitoring systems. The product range includes solutions for use in roof-mounted systems and large solar farms. Depending on the version, the boxes can contain terminal blocks, surge protection, fuses and load circuit breakers and even systems that permanently monitor the performance of the strings.
