As PV systems have grown in size, so have the
corresponding voltage requirements. This increase in
system voltage has typically been intended to minimize
power loss associated with long conductor runs. Standard
circuit protection devices are not designed to completely
protect photovoltaic panels. However, the SPF series is
UL Listed to safely interrupt faulted circuits up to this
demanding voltage level.

A key objective for panel designers is safe distribution of

Littelfuse UL508 bus bar system eliminates most wire

frequencies from 0-15,000 Hz. Two CT’s are required for the
entire frequency range, or one CT can be used for only lowor high-frequency detection. An RTD/PTC sensor input
allows over-temperature protection. The EL731 offers
metering capabilities, password-protected alarm and trip

add low-level ground-fault protection to variable-speed
drives, and to dc currents.

TVS (transient Voltage Suppression) Diodes
What Are Voltage Transients?
Integration of Transient Voltage Suppression (TVS) components
within solar system designs help to prevent the damaging effects
of transient events, and assure compliance to safety and
reliability standards.
Voltage transients are unwanted short duration surges of electrical
energy. They may result from the sudden release of previously
stored energy, and can come from internal and external sources.
If the voltage magnitude of the transient is large enough, circuit
component damage or malfunction of the circuit may result.
TVS and Solar Inverter Protection
A PV solar system component particularly vulnerable to transient
voltage effects is the power inverter. Its range of functions and direct
connection to other system components enables vulnerability of
transient voltage transfer. For example:
Transients can occur either repeatedly or as random impulses.
Repeatable transients are frequently caused by the operation of
other system components, such as motors, generators or the
switching of reactive circuit components. Random transients,
are often caused by lightning, electrostatic discharge (ESD),
and other outdoor environment events.

•
Conversely, transients originating from the outside utility power grid
may pass through the main circuit panel and cabling to the inverter.
•
Startup of motorized equipment (such as power tools, tracking
systems, fan motors) enable vulnerabilities produced by repeat
load changes.
•
Electrostatic discharge events generated internal and external
to the system may pass between the inverter and sensitive
electronic control equipment.

TVS Diodes are used to protect
semiconductor components from
high-voltage transients. Their p-n
junctions have a larger cross-sectional
area than those of a normal diode,
allowing them to conduct large
currents to ground without sustaining
damage. Littelfuse supplies TVS
Diodes with peak power ratings
from 400 W to 15 kW, and reverse standoff voltages from 5 V to 512 V.
Lightning-induced transient events may pass through the solar
array and outdoor cabling to the inverter (and other sensitive
electronic equipment in the path).
For these reasons, it is important to build surge withstand ability within
the inverter as well at locations before damaging transients may reach
sensitive equipment.
