Anderson Power Products SB® connectors are available in several sizes: 50 amp, 175 amp, and 350 amp, which are the most popular. We stock many colors, such as yellow 12 volt, orange 18 volt, red 24 volt, gray 36 volt, blue 48 volt, green 72 volt, and black 80 volt. Each color will connect only with a connector of the same color and size.
Usually, the 50 amp connectors connect to small-medium array connections (parts of larger systems) and small power and battery connections. The 175 and 350 amp units connect to larger batteries and large arrays. Some inverter connections may use these as well.
