Connect the individual components to the symbols provided, they are
solar panel, battery and loads in order. Only install the regulator near the
battery on a suitable surface. This surface should be solid, stable, even,
dry and nonflammable. The battery cable should be as short as possible
(1-2m) and have a suitable cable diameter size to minimize loss, e.g. use
2.5mm

at 20A.
Observe the following connection sequence during commissioning
：
1) Mount the controller to a vertical surface. Allow space above and
below the controller for air flow. Note: the mounted ambient
temperature should not be over the working temperature of controller
（
-10
℃
~60
℃）
；
2.Connect the po of battery to the fuse
，
and then connect the battery
to the controller. The current of fuse should be chosen 3-4 times of rated
current. Note the plus and minus.
3. Connect the photovoltaic module to the charge regulator
-
plus and
minus
4. Connect the consumer to the charge regulator
–
plus and minus
Please observe that the automatic adjustment to 12V/24V
systems does not function properly, if this sequence order is not
followed. An improper sequence order can damage the battery!
5.The parameters can be set depending on
the user’s need.
6.The negative battery is grounded or ground connected as the above.
