Weidmüller PV Next generator connection box for string inverters with 2 MPPT DC 3I 3O

The PV generator connection box from Weidmüller (MPN: 2890600000) reliably protects your solar system against overvoltage and short circuits.It presents you with the world's first concept based on a standardized circuit board design. This is not only extremely robust, but also helps you save on material costs. Thanks to the integrated PUSH IN technology and the plug-and-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 unwanted high voltages. Installation is easy, as you do not need any special tools or prior crimping.

Your advantages at a glance

Simple – Thanks to the unique circuit board design, additional functions can be integrated quickly and easily. This means that you can easily add a switch or connect a second MPPT directly to the existing circuit board, for example. This flexibility ensures that your PV system is easily expandable and adaptable, so 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.

Compatible with all inverters

The connection box product portfolio has been specially developed to provide comprehensive protection for string inverters with 1-12 MPP trackers. This ensures optimal 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.
