What is a combiner box?
A combiner box is a key DC distribution device used between PV strings and the inverter. Each string consists of solar modules wired in series, and the combiner box gathers multiple strings into a single output while ensuring safety and system efficiency. Current Collection: Consolidates DC output from 6–24 strings into busbars.
How many PV string inputs can a combiner box support?
A standard combiner box supports 6–24 PV string inputs, with typical current per string ranging from 10–20A. Key features include: Reverse current protection is essential when module shading or mismatched strings cause imbalance. 2. Multiple Layers of Electrical Safety Protection These protection layers significantly reduce system downtime.
What is an external DC combiner box?
