PRECAUTIONS
CAUTION:
If it is a 12V system, the bottom left corner of the LCD display will show '12V', '24V' system will show
24V.
CAUTION:
The first step is to connect the battery. If the connection is made correctly, the controller screen will
light up; otherwise, check whether the connection is correct.
CAUTION:
The second step is to connect the solar panel. If sunlight is present and strong enough (the solar
panel voltage is greater than the battery voltage), the sun icon on the LCD screen is on; otherwise, check whether
the connection is correct. (It's recommended that the operation be performed under the debugging mode).
CAUTION:
The thirds step is to connect the load. Connect the load leads to the controller's load output terminal
and the current shall not exceed the controller's rated current.
CAUTION:
As the controller will generate heat during operation, it's recommended that the controller be
installed in an environment with good ventilation conditions.
CAUTION:
Choose cables with large enough capacity for connection, in case too much loss incurred on the
lines causes the controller to misjudge.
CAUTION:
The controller has a common positive pole inside. if grounding is needed, ground the positive pole.
CAUTION:
It's important to fully charge the battery regularly. At least one full charging every month is
recommended and failure to do so may cause permanent damage to the battery. Only when in-flow energy
outpaces the out-flow energy can the battery be charged fully. Users shall bear this in mind when configuring the
system.
CAUTION:
Check whether the controller's connection terminals is tightened securely; if not, it may suffer
damage when large amounts of current pass through.
