WARNING:
A reversed string is not protected by the inverter and can cause
severe damage to equipment and personnel. A reversed string is
extremely hazardous and will result in a blown fuse when the
irradiation is high. The voltage across the blown fuse will be 2x Voc
and could prevent proper fuse operation resulting in a fire.
