Caution
Lightning surge suppression- Lightning does not actually need
to strike the equipment or building where the PV system is
installed to cause damage. Often, a strike nearby will induce
voltage spikes in the electrical grid that can damage equipment.
Darfon’ s Micro inverters (MIG240UL00) have integral surge
protection, much higher than most traditional inverters. However,
if the surge has sufficient energy, the built- in protection in the
device would exceed, and the device can be damaged.
As the Darfon Limited Warranty does not cover “extraordinary
and unexpected manifestation of the forces of nature,” such as
lightning strikes, therefore it is recommended to install surge
protection as part of any solar installation.
We recommend the following protection devices. These have
