Grid-Tie
Off-Grid Solar PV Systems
Off-Grid PV systems
– Stand alone system
– Battery back up
– Low voltage electricity
generation 12, 24, or 48V
– Typically provide DC power to
smaller systems (lights, signs,
etc)
– “I don’t want to run power from
the line side”
Off-Grid Solar PV Systems
Grid-Tied Solar PV Systems
 Grid-Tied (on-grid) PV systems
– System that is connected to a large independent
grid (typically public) and feeds power into that
grid
– The electricity demand is met by the system and
the excess is fed directly to the grid
– Inverter is required to convert DC electricity to AC
– Used in high voltage electricity generation – 6001000V (buildings, residential rooftops, solar farms)

Solar Pass
Through Boxes
Solar Pass Through Box
 Used in residential
applications
 Provides low profile, cost
effective solution
 Transitions solar PV wire
into traditional building wire
 Designed for PV
applications where over
current protection is not
necessary due to the low
power rating of the PV string
 Sometimes referred to as a
“Transition Box”
 Available in 3 and 4 circuit

Solar Nonmetallic Cord
Grips
Solar Cord Grips
 Used in residential
applications
 Multi-hole design allows for
the entry of multiple PV
wires coming into a
combiner or pass through
box
 Provide mechanical strain
relief as well as a liquid tight
seal around the solar panel
wires
 Available in 1” (9 hole) and
1-1/4” (13 hole)
