Weidmüller pv Next generator connection box for string inverters with 2 mppt dc 3i 3o

The pv generator junction box from Weidmüller (mpn: 2890600000) 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 2 MPP trackers. 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.

Your benefits at a glance

Simple - Thanks to the unique PCB design, additional functions can be integrated quickly and easily. This means that you can easily add a switch, for example, or connect a second mppt directly to the existing PCB. This flexibility ensures that your pv system is easily expandable and customizable and that you are optimally prepared for future requirements.
Fast - With push IN connection technology, pv Next offers the simplest and safest concept for cabling. Installation is child's play and requires neither crimping nor special tools.
Safe -with the combination of these two features, you benefit from easier quality assurance and avoid the risk of incorrectly tightened screw connections, which can be a major cause of fires.

Fits all inverters

The product portfolio of junction boxes has been specially developed to provide comprehensive protection for string inverters with 1-12 MPP trackers. This ensures optimum coverage for all common inverters on the market.

Plug & Play

Choose the WM4 C solar connector for the ready-to-use housing and significantly reduce your connection time. Alternatively, you can use cable glands and individual cabling.
