The SPECIALTY CONCEPTS CHARGER MODEL 1 (SC1) is a versatile, industrial quality charge
controller for the efficient use of photovoltaic energy and the protection of expensive batteries. It
is available for 12, 24, 36, and 48 volt negative ground systems with models for 30 amps of
charge current (optional 50 amps available) .
The SC1 consists of a series-relay battery charge controller in a wall mount chassis with low
voltage load disconnect, a load circuit breaker, and system status lights. The lights indicate
"CHARGE MODE" and "LOAD DISCONNECTED" conditions. The SC1 is housed in an anodized
aluminum chassis and has a terminal block that accepts up to 10 gauge wire. A terminal adapter
kit is included to increase wire size to #6.
