Please notice the cable supplied is around 300cm. Do not pull cable too hard avoid
loose contact loose.
4.4.6 PV array connection
A diode was requested to be added between PV array and SP charge controller
preventing current from battery damage the PV array at night.
The Voc (open circuit voltage) of PV array must never exceed 150Voc. The PV array
Isc must not exceed the nominal current of SP at any time (60A or 80A). Please also
consider the local temperature condition which might result in the increase of PV
array Voc/Isc. Refer to chapter 4.1
Whenever a PV array is exposed to light, a shock hazard exists at the output of wires
or terminals. To reduce the risk, cover the array with a dark material before making
the connection.
Choose the right cable size (refer to 4.3) and follow polarity guide marked on the panel
Adding diode between PV array and MPPT preventing reverse current at night to PV.
An over current protection devices DC fuse or circuit breaker needs to be installed on
positive cable, of which rated for 100% of the nominal rating.
