Issue Description
PV modules provide no or low voltage outputs. For example, in a sunny day, the open circuit voltage of a single PV module is less than 12 V for a 140 W PV module or less than 24 V for a 190 W PV module.
Solution
Possible Cause:The bypass diode is burnt due to lightning strikes

Measure: Replace the PV modules
