Your benefits at a glance

Easy

The unique PCB design allows quick and easy integration of additional functions. For example, a switch can be integrated or a second MPPT can be connected directly to the first PCB.

Quick

With the PUSH IN connection technology, PV-Next offers the most straightforward and safest connection concept for cabling. The installation can be carried out without crimping and without special tools.

Safe

The intuitive design and PUSH IN connection technology make installation safer and quality assurance easier. The risk of screw connections with incorrect torque is eliminated, which is one of the main risks for fires.

The most innovative concept for string inverters

5 Sizes of the box

Depending on your application PV Next is available for up to 6 MPPTs per box. Fused for up to 2 and for non-fused for up to 3 sizes. A free scalable system.

Fused and non-fused

The fused version is optional for protection of the panels from reverse current. The pcb without additional fuses is slimmer.

Surge protection

All boxes are protecting your panels or inverters from surges. Our standard protection on the pcb are arresters in type 1.

PUSH IN connection on board

The integrated maintenance free PUSH IN technology for the inputs/ outputs significantly reduces working time and error susceptibility.

Plug & Play connection

Choose the WM4 C connection for the ready-to-use box and reduce your operation time significantly. The other option is to choose cable glands and do your individual cabling.

Switch on request

For many solar engineers it is important to have a switch on the box. In other regions it is not necessary. Your choice!

Variable string bundling

With our cable grafting variants, you can decide for yourself whether you want to bundle the strings together or whether you want to remove the same number again. The sealing set that is included covers both possibilities.

Protects all demands

From 2IN, over 2MPPT up to 6MPPT or 6IN-1OUT up to 6IN-6OUT - we can now protect every need with our boxes.
