Connection Instruction
Preparation of the wire
Adopt the wire matching the current
,
plan the length of wire, strip 5mm insulation of one side of the
controller’s terminal and try to decrease the length of the connected wire so that a reduction in
electrical loss.
Battery connection
Pay attention to the pole + , - , do not connect reversely. If connect correctly, the controller will start to
work or it’s necessary to check the wire connection and battery’s situation. Users could connect the
system followed by the order showed in the below figure.
Photovoltaic module connection
Pay attention to the pole + , - ,if sun light is tested, photovoltaic indicator will light on or it’s necessary
to check the connection.
Load connection
Connect the load wire with the controller’s output terminal, the current can’t surpass the controller’s
rated current and pay attention to the + , - pole, for avoiding damage to the device ,do not connect
reversely
Temperature sensor connection
Connect one side of the temperature sensor to controller, the other side to the battery. There must be a
good thermal contact with the battery shell.
