Description
Product Parameters
Product Introduction

EKDBS-PV4/1-FBS-1000 is a heavy-duty 1000V DC combiner box designed for higher current applications with 4 input strings. This professional-grade unit features advanced MCB protection instead of standard DC isolators, making it ideal for large commercial and utility-scale solar installations where higher output currents are required.

 

Applications:

EKDBS-PV4/1-FBS-1000 is specifically designed for larger commercial and utility-scale solar installations where multiple high-current strings need to be combined, such as:

• Large commercial rooftop solar arrays

• Ground-mounted commercial solar fields

• Solar carports and canopies

• Industrial solar power systems

• Small utility-scale solar installations

• Applications requiring higher output currents up to 63A
