6) Always connect the battery first, in order to allow the controller recognize the system voltage.
7) The battery fuse should be installed as close to battery as possible.
8) The distance between the battery fuse to battery group is within 150mm
9) Positive grounding controller, any positive connection of solar load or battery can be earth
grounded as required.
10) AII terminals are in tight status after leaving factory, in order to well connected, please loose all
terminals at first.
11) The sequence of connection please do not free change, otherwise cause system voltage
recognition fault.
12) The length of cable between battery and controller as shorter as possible. Suggest 30cm to
100cm.
13) lf short circuit happened on the terminals of controller, it will be result in fire or explode. Please
be careful. (We strongly suggest to connecting a fuse at the battery side 1.5 time of rated
current of controller)
14) If the battery reverse connection, the output of controller also same with battery polarity, please
do not connect any load with controller at that time, or the load and controller will be destroyed.
15) The voltage of solar panel is very high under sunshine, high voltage can cause injury or destroy
controller, make sure PV
max
under required safety MPP range.
16) Avoiding injury from load voltage, please close to the output of controller with button at first,
then connected the load on the controller. The controller do not offer reverse connection
protection for load, so please take care, reverse connection for load will be destroy bulb.
6 OPERATION STEPS
Main interface
1) The controller will have Is initialization interface after electrified, then go into main interface.
