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 have integral surge protection; however, if the surge has sufficient
energy, the built-in protection in the device would be exceeded and the device could potentially be
damaged. It is recommended to install surge protection as part of any solar installation. We recommend the
following protection devices, which have been tested to ensure that they do not interfere with power line
communications.
Residential: Vendor: Citel, Part Number DS72RS-120 or DS73RS-120
Application: DS72RS-120 is applied when N-G is bound together, or DS73RS-120
were N-G is unbound.
Commercial: Vendor: Citel, Part Number SP-120
Application: Branch panel protection
See the vendor datasheet for DS70R (includes the DS72RS-120) or SP-120 at

FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, you are encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance may void the
user’s authority to operate the equipment.
