Introduction
Photovoltaic systems are composed by photovoltaic panels,
cables, fuses, switches, overvoltage arresters and power inverter.
Photovoltaic panels utilize the power of sunlight to converters
photons to DC current.
Electricity generated by solar panels is then fed into a power
inverter that converts DC current to AC current. gPV fuse has
been developed to protect cable and panel against «reverse»
over current.
MERTRONIC B, C-PV series of over voltage surge protective devices
has been developed to protect against direct and indirect lightning
discharges and is intended to protect photovoltaic systems.
The circuit topology consists of two varistors stages each
protected by a thermal disconnection device.
Over Current Protection
• PV module protection from »DC REVERSE« current on DC side
Array with three or more strings of panels:
PV systems that have three or more strings connected in parallel
need to have each string protected by fuses.
Systems that have less than three strings will not generate enough fault current to damage the conductors/solar panels.
Normally there are two gPV fuses connected on each string (+ and - pole) that protect conductors/solar panels from
damage and eliminate any safety hazards.
Fuses isolate the faulted string. The rest of PV system can continue to generate electricity.
• PV module protection from »AC REVERSE« current caused by defective inverter
If an inverter becomes defective (transformer less …), AC reverse current can feed into DC strings and destroy PV
modules.

MERTRONIC C - PV
MERTRONIC C-PV series of overvoltage surge protective devices has been developed
to protect against indirect discharges and is intended to protect photovoltaic
systems.
The circuit topology consist of two (three) varistors stages each protected by a thermal
disconnection device.

PV Switch Disconnector for Photovoltaic / Switch Disconnectors and Load
The construction of the switch ensures reliable switching up to 58A with 1000V in the category DC 21B.
The construction of the contacts and the material selection guarantee that no oxidation (small switching frequency
develops, and is thus prevented inadmissible heating-up.
The switch disconnector has 2, 4 or 4+2 contacts, by serial / paralel wirring of the contacts the contact rating will be
increased.
The switching speed at the manually operated handle does not have an effect on the switching attitude of the
contacts.

EVE - Modular Devices
Utility grid monitoring relays HRN-54 and HRN-54N serves
to monitor voltage, phase failure and phase sequence
and perform anti-islanding protection together with ETI
multifunction time relays CRM-91H and CRM-93H.
• HRN-54
• HRN-54N
• CRM-91H
• CRM-93H
Application:
Anti-islanding protection for photovoltaic systems.
Build-in switch is used as a main switch in distribution boxes in houses
or as a switch for individual electric circuits. With a build-in switch we can
completely replace the cam switch. Build-in switch can be sealed either
in ON or OFF position.
Available in 1-, 2-, 3- and 4-pole versions.
MERSWITCH - Switch Disconnectors
MERSWITCH Switch diconnectors series LAS and built-in switches series
SV serves as control switches, load break switches and disconnecting
devices in AC distribution/protection cabinets.
• LAS16 up to LAS125 (3,4-pole, from 16 to 125A)

MERTRONIC - Motor Contactors and MERBREAK - MCCBs
MERTRONIC power contactors are used as separation device actuated on antiislanding protection signal between photovoltaic inverter and AC utility grid.
For the same purpose MERBREAK moulded case circuit breakers series EB2
assembled with motor operators enabling remote controlled operations can
be used. EB2R moulded case circuit breakers with integrated residual current
protection provides combined protection against overloads, short-circuits and
residual currents.
• CEM 9 up to CEM300 (AC3 9 up to 300A)
