XW MPPT60-150 Shows low light
 
NOTE:  The PV input must be greater then Battery voltage by the following factor

Battery voltage plus a factor of 0.25 V per 12 V. For example, in a 24 V system, if the battery voltage
is 27.0 V and the PV array is producing 27.4 V, the Low Light message appears. The Low Light
message clears when the input voltage rises above the battery voltage plus a factor of 1 V per 12 V.
THIS IS NOT MEANT TO IMPLY THE ARRAY CAN BE CONFIGURED TO THE SAME VOLTAGE AS THE BATTERY. ALWAYS HIGHER.
