25 foot (7.62 m) long cable with SAE connectors on both ends. Standard 2-pin hermaphroditic DC conductor common in solar. Often used to connect solar systems to batteries.
SAE connectors are used by ASP Solar Generator systems to connect from the Combiner Box to the Charge Controller, and from the Charge Controller to the output panel sockets (SAE cables and 12V Lighter DC or optional Amphenol Bayonet socket). This extension cord can be used between components or to connect from the SAE socket to a battery pack.
