Weidmüller pv Next generator connection box for string inverters with 1 mppt dc 3i 3o

The pv generator junction box from Weidmüller (mpn: 2890590000) reliably protects your Solaranlage from overvoltages and short circuits. It presents you with the world's first concept based on a standardized circuit board design, which is not only extremely robust, but also helps you save on material costs. Thanks to the integrated push IN technology and the plug & play principle, installation times are significantly reduced and the risk of errors is minimized. It is perfectly designed to work with inverters that have 1 MPP tracker. This means that it not only protects the electronic side of your system, but also ensures that your inverter is protected from undesirably high voltages. Installation is simple as you do not need any special tools or prior crimping.
