A DC combiner box safely connects PV strings to the inverter. It provides surge protection, overcurrent protection (optional), and a centralized connection point for solar installations.
This model is designed for single-string systems where fuses are not required by code (NEC 2017/2020 allows fuse-free for 1-2 strings). It reduces cost and maintenance. For multi-string systems, consider our 2/4/8-input models with individual string fuses.
SPD (surge protection device) is highly recommended and required by many local codes (NEC 2020 Section 690.12). It protects your inverter from lightning strikes and voltage surges.
