Willmall photovoltaic connectors join and extend solar DC cabling with positive locking, keeping array connections electrically sound in outdoor service.
They connect the DC cables of a solar array, joining modules, extension leads, and inverter inputs with a locked, sealed interface.
The lock keeps the two halves engaged under pull and thermal cycling, preventing loose connections that could heat or fail.
The connector is rated for the DC system voltage and the string current, matched to the array and inverter.
The cable is prepared and the housing pressed together, typically without specialised crimping tools on standard versions.
It is used in string cables, module extensions, and inverter-side DC wiring exposed to outdoor conditions.
