3.1 Product overview
Weidmüller PV Next String Combiner Boxes are standard-
ised string combiners that are used to safely and easily
connect photovoltaic string cables to inverters in private or
commercial PV systems.
The product family includes multiple power ratings. The
variants with string protection include gPV fuse links to pro-
tect against impermissibly high return currents.
Depending on the design of the PV system, up to 6 electri-
cally isolated maximum power point trackers (MPPT) can
be connected.
Per MPPT, each PV Next String Combiner Box contains
a replaceable type 1/11 o r type II DC surge protection. The
boxes are optionally equipped with a switch-disconnector.
The connections to string cables and inverters are made
either with PV connectors
sure or via a direct connection
The type designation of your product can be found on the
type plate inside the enclosure.
