SeCtIOn 2 | Features of the SCC-1208l
Battery Low Voltage Disconnect
Another facility is provided where the load connected to the Load Terminals will be
disconnected to prevent deep discharge of the battery. Deep discharge of the battery is
more likely when the load is being powered during night time through the Night Light
Function. If the battery voltage drops to less than 11.5 V continuously for 5 min the load
will be switched off at the end of 5 min. The load will be automatically re-connected if
the battery voltage rises to 12.4 V for 5 min. If the battery voltage drops to 9 V, the load
will be disconnected immediately (there will be no time delay).
SeCtIOn 3 | Installation & Operation
!
cAUtion
1. the unit has internal protection circuits that are activated only when a
battery is connected to the unit. Hence, please ensure the following to
protect the unit against damage:
• Always connect the battery first and then the solar panel / array
• Do not disconnect the battery when the solar panel / array is
connected. If the battery is required to be removed for servicing /
replacement, remove the solar panel / array first and then
the battery
2. A battery is an unlimited source of current and can drive thousands
of Amperes of current into a short circuit across its terminals. if there
is a short circuit along the path of the battery connecting wires from
the battery to the controller, the section of wires from the battery to
the point of short circuit will melt and burn and may cause injury/ fire.
Hence, always install a current limiting type of fuse e.g. class t fuse or
equivalent as close to the battery Positive terminal as possible
3. Doubly check the polarity of the connections with the help of a multi-
meter. ensure that Positive is connected to Positive and negative to
negative. Avoid connecting in reverse polarity. the unit has internal,
self resetting protection against reverse polarity on the battery side
