A combiner is a device used in solar energy systems to combine the output of several smaller solar panels into a single larger panel. Combiners are typically used to connect multiple photovoltaic (PV) modules in series, parallel, or both. Combining PV modules in this way allows systems to produce more power while taking up less space, making them a popular choice for residential and commercial solar installations.
The key components of a combiner typically include durable housing to protect the electrical connections, as well as fuses or circuit breakers to provide additional safety and prevent damage in case of overload or short circuit. Combiner boxes are also designed with heat sinks that help dissipate excess heat, preventing the electrical components from overheating.
