Important safety information
- It is better to install the controller in the room. If install the
controller outside, please keep the environment dry, avoid direct
- The controller will be hot in process of working, please keep the
environment ventilation, away from the flammable.
- The open circuit voltage of solar panel is too high, (especially
24V system), please take care.
- The battery has acidic electrolysis, please put on goggles during
installation. If you accidentally exposed to the electrolysis,
please rinse with water.
- The battery has huge power, prohibit any conductor short circuit
the positive and negative pole of battery. Suggest to adding a fuse
between battery and controller. (slow motion type, the action
current of the fuse should be 1.5 times rated current of
1) The controller should be installed well-ventilated place,
avoid direct sunlight,high temperature and do not
Install in location where water can enter the controller.
2) Please select correct screw to fix the controller on the
wall or other platform. Screw M4 or M5,Screw cap
diameter less than 10mm.
3) Please reserve enough space between the wall and
controller,to allow for cooling and cable connection.
