Photovoltaic (PV) Combiner Box

​

Introduction

The use of PV Combiner Box is essential equipment for all photovoltaic systems. It is considered the interface between the solar inverter and solar panels. In a photovoltaic system, the modules are arranged in strings and arrays depending on the type of inverter used, the total power and the technical characteristics of the modules. Clovis offers a complete range of all-in-one PV combiner boxes hosting string protection devices, disconnect switches and surge protective devices (SPDs).
