Solar Array Requirements - Adventure Kings PLUS AKPSR-MPPT 01 User Manual

7. Once the wire is securely in the metal terminal block, tighten the screw firmly
8. Repeat for both the battery positive and negative terminals (with one quick
connect plug) and the solar + and – terminals with the other quick connect plug
9. Confirm the polarity of the Solar input plug is connect
10. Confirm the polarity of the Battery plug is correct
11. When mounting the charge controller use screws or bolts, nuts and washers to
ensure it is secure and cannot move or shake loose
12. Allow for 150mm of free space above and below the heat sink
13. Do not mount the Charge Controller on any surface that will be or could be
affected by high temperatures

5. SOLAR ARRAY REQUIREMENTS

The Adventure Kings Plus MPPT Charge Controller has an in-built charging current/
power-limiting function. During the charging process, when the charging current or
power exceeds the rated charging current or power, the controller will automatically limit
the charging current or power to the rated range.
This function protects the controller and prevents damage to the controller due to the
connection of some over-powered PV modules. The actual operation of PV array is as follows:
If charging current or power of the solar panel(s) is less than or equal to the rated
charging current or power of controller it will carry out the charging as per the actual
current or power available at the time. At this time, the controller can work at the
Maximum Power Point of the solar panel(s).
WARNING
Even if the solar panel power is less than the rated charging power, if the
maximum open-circuit voltage of the solar panel exceeds 60V (at the lowest
environmental temperature), the controller may be damaged.
If charging current or power of PV array is greater than the rated charging current or
power of controller, it will charge at the maximum rated current (20A) or power (260W on
a 12V system).
