The Voc of PV array must never exceed 150V for SP150-YYY and 250V for
SP250-YYY ;The PV array Isc must not exceed 70A at any time.
The Voc or Vmpp of solar panel was rated at 25℃ with normal weather
condition. Along with temperature reduced, the Voc/Vmpp of solar array will
increase. Please consult with PV manufacturer for Voc/Vmpp of the lowest
possible environment temperature and making sure it is below 150VDC for
SP150-YYY and 250VDC for SP250-YYY.
 PV array with Isc up to 80A was recommended for SP series to allow for increase of Isc
caused by irradiance enhancement under certain condition.
 Please ensure the PV array used in the system operates within the MPPT operational window.
Following table shows effects of different PV array voltage.
