photovoltaic application guide

Solar Photovoltaic (PV) systems have evolved into a mature, sustainable and adaptive

technology. The growth in installations and demand for PV systems necessitate effective

electrical protection. PV systems, as with all electrical power systems, must have

appropriate overcurrent and overvoltage protection.

Eaton has worked closely with solar system manufacturers, and through coordinated

research and development, has produced revolutionary photovoltaic fuse links which

work in combination with solar array combiner systems to offer a complete protection

for PV applications.

Eaton has more than 100 years of proven

technical innovation to help make your

operation more productive while protecting

your equipment.

EATON Bussmann series photovoltaic application guide 5

Introduction

The global transition from fossil fuels to renewable sources is well under way. Photovoltaic

(PV) have proven to offer an environmentally sustainable solution to our ever increasing

energy demands while also being cost competitive. This has led to the increase of

installed capacity of PV systems from 574 GW in 2019 growing to 1064 GW expected

by 2023. This rapid growth size and output capacity of these installations has challenged

system designers, manufacturers and standards organisations due to the specific demands

associated with PV installation in terms of current, voltage, and ambient temperature.

These requirements have also been considered in the development of international

protection standards for PV installations, which Eaton, the leading name in electrical

protection, has used to develop PV specific protection devices.

Unlike typical grid connected AC systems, the available shortcircuit current within PV systems is limited and the

overcurrent protective devices need to operate effectively on

low levels of fault current. For this reason Eaton has

conducted extensive research and development of fuse links

that are specifically designed and tested to safely protect PV

systems with high DC voltages and low fault

currents.

The International Electrotechnical Commissions (IEC) recognise

the protection of PV systems is different to standard

electrical installations. This is reflected in IEC 60269-6 which

defines specific characteristics that a fuse link is required to meet

for protecting PV systems, utilisation class gPV. Eaton’s Bussmann

series string and branch PV fuse links have been specifically

designed to meet this standard. However, Eaton’s Bussmann

series PV fuse links exceed the requirements of IEC 60269-6 as

they operate at 1.35 x In (1.35 times the nominal current). They

also meet the requirements of UL 2579 and are thus suitable for

protecting PV modules in reverse current situations.

Whilst the standard does not recognise a specific symbol, the

combination of the symbols for fuse link and strings are often

used to indicate a fuse link is suitable for protecting strings in PV

systems, see Figure 1.

Photovoltaic module construction

Figure 2

Photovoltaic module output

The voltage output of a PV module is defined by the number of cells in series that form the

module.

The current output of a PV module is dependent on the area of a cell.

The most widely used solar modules are made with 4’’, 5’’ and 6’’ poly-crystalline silicon cells.

This type of module using 6’’ cells, can achieve approximately 8 Amps maximum power point

(MPP) current per module with a typical voltage output of around 30 Volts.

With thin film technology typical output is 2.5 Amps and 40 Volts.

The maximum power point current of the modules vary between manufacturers of equal solar cell

dimensions. When selecting the appropriate fuse links, the specified Short Circuit Current (Isc) and

reverse current characteristics specified by the manufacturers should be used.

The specifications provided by the module manufacturer should be consulted to confirm the output

currents and voltages of the modules under the range of conditions expected for the proposed

installation. These conditions are influenced by the ambient temperature, the incident angle of

sunlight and the amount of solar energy reaching the module. These are usually mentioned as

coefficients on the manufacturer’s specifications.

Manufacturers also suggest the maximum series fuse rating or a reverse current rating. Both of

these are based on modules surviving 1.35 time this rating for two hours.

• A photovoltaic (PV) cell is usually between 4” and 6” square.

• A number of individual cells are combined in a module (often called a panel).

• A number of PV modules in series is referred to as a string.

• A number of strings in parallel is referred to as an array.

EATON Bussmann series photovoltaic application guide 7

Overview of string protection

Depending on the desired capacity of the Photovoltaic (PV) system, there may be

several PV strings connected in parallel to achieve higher currents and subsequently

more power.

PV systems that have three or more strings connected in parallel need to have each string protected.

Systems that have less than three strings will not generate enough current to damage the modules

in the event of a fault. Therefore they do not present a safety hazard, provided the conductor is sized

correctly, based on local codes and installations requirements.

Where three or more strings are connected in parallel, a fuse link in each string will protect the

cables and modules from overcurrent faults and help minimise any safety hazards. It will also isolate

the faulted string so that the rest of the PV system can continue to generate electricity.

It should be remembered that PV modules current output changes with the module temperature as

well as the amount of sun they are exposed to. The exposure is dependant on irradiance level, incline

as well as shading effect from trees, buildings or clouds. In operation, fuse links, as thermal devices,

are influenced by ambient temperature. The current capability of Eaton’s Bussmann series PV string

fuse links should be derated according to the curves below.

How to select fuse links for string protection

Whilst a full study of all the parameters is recommended, the following factors should be used: 1.56 for current and 1.2 for voltage when

selecting the fuse link. These cover most variations due to installation. The same method should be adopted for crystalline and thin film

modules.

If your PV installation is subject to extremes of high altitude, high irradiance, or low temperature, please consult Eaton’s Field Application

Engineers: bulehighspeedtechnical@eaton.com.

manufacturers as the maximum series fuse rating)

If Np  3 and the cable is rated at 1.56 x Isc

For PV installations with three or less parallel strings and string cables adequately sized, fusing might be needed if local installation

regulations or codes require them.

However Eaton recommends fuse links protection in all PV systems as unpredicted fault currents may occur in the event of inverter

failure where batteries are connected to the strings.

If Np > 3

The fuse link’s rating should be selected as follows:

• Voltage rating 1.20 x Voc x Ns

• Current rating  1.56 x Isc

• Check the current carrying capability of the selected fuse after derating at the ambient temperature of the fuse still satisfies the

above criteria

• Current rating I

• Current rating I

• Altitude derating

Cable protection

Fuse links are required to protect cables and PV modules to prevent fires and ensure the fuse could open a fault circuit safely during an

overcurrent fault.

For Np 3, a fuse might not be required as stated above, but cable should be rated at 1.56 x Isc or higher.

For Np 3, a fuse is needed to protect both the PV modules and the cables. The cable should be rated big enough to carry the load

current. If cable rating is too small, there is a risk of nuisance tripping. Also it is important to ensure the fuse link current rating < string

cable rating for fuse to protect the cables.

reduces. For above 2000 metre sea level, every 100 metre increase will have 0.5% de-rate on the fuse current. Please consult Eaton’s

String protection — worked example

Once it has been determined that the maximum short-circuit current exceeds the cable’s continuous current rating, the

recommendations for selecting the correct PV string fuse link are as follows:

The selected fuse link needs to be rated at 10 A and 1000 V d.c.

Eaton’s Bussmann series catalogue is PV-10A10F

The selected fuse link has current carrying capability of 9.3 A at 45o

C ambient temperature, which is greater than the minimum fuse current rating (8.38 A). Therefore the fuse link selected will protect the cables and the modules against reverse

current faults.

10 EATON Bussmann series photovoltaic application guide

Overview of array protection

Depending on the desired capacity of the Photovoltaic (PV) system, there may be

several PV strings connected in parallel to achieve higher currents and subsequently

more power.

A fuse link on each array will protect the cables from fault current and help minimise any safety

hazards. It will also isolate the faulted array so that the rest of the PV system can continue to

generate electricity.

A fuse link positioned in the cable that carries the combined output of a number of strings should be

protected by array fuse links. If a number of arrays are subsequently combined then a further fuse

link should be incorporated.

It should be remembered that the characteristics of PV modules vary with module temperature as

well as irradiance level. In operation fuse links are influenced by ambient temperature.

In accordance with the National Electrical Code (NEC) fuses are selected using 1.56 x Isc. .

As fuse manufacturer, Eaton’s recommends

the array fuse selection method below in order to satisify both IEC and NEC requirements.

The fuse link’s ratings should be selected as follows:

• Voltage rating  1.20 x Voc x Ns

Description

Eaton’s Bussmann series 10 x 85 mm fuse holders are suitable for

use with 10 x 85 mm and 14 x 85 mm cylindrical gPV fuse links.

The unique design offers high degree of safety. There is no

possibility of any accidental contact with live parts during replacement of the fuse links. When the fuse carrier is extracted, a spring

loaded cover moves out covering the live parts hence protecting

against accidental damage.
