Product Introduction

The EKDBT-PV12/1-FBS-1500 is an industrial-grade 1500V DC combiner box engineered for utility-scale and large commercial solar installations. Featuring a rugged metal enclosure (IP65/IK10) and high-current handling capabilities, this unit provides superior protection and reliable string management for high-voltage PV arrays.

This unit's 1500V high-voltage design significantly reduces system costs by enabling longer string lengths and decreasing balance of system requirements compared to traditional 1000V arrays.
