In every photovoltaic (PV) system, stable power generation relies on more than panels and inverters. Hidden behind the scenes is a critical piece of equipment: the PV combiner box. Though easy to overlook, this device plays a decisive role in current collection, circuit safety, surge protection, and intelligent monitoring.
What is a Solar Combiner Box? A Solar Combiner Box is an essential electrical device used in photovoltaic (PV) power generation systems. Its primary function is to combine the output currents of multiple solar panel strings (PV strings) into a single output, which is then sent to the inverter for DC to AC conversion.
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.
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.
