Solutions for photovoltaic systems

ProtectPlus. The OBO system kit for comprehensive protection of photovoltaic systems.


As the installation engineer of a PV system, you carry the responsibility.
Not a problem with ProtectPlus.

The erection of a photovoltaic system often requires major intervention in the electrical infrastructure of a building. This is reflected in the wide range of standards and regulations to be complied with. The person erecting the system is liable for correct fulfilment for 30 years, and the requirements of the insurance company come on top of that.

Responsibility of the operator
Through the feed-in of the gained energy, almost every PV system is subject to the requirements for commercial use. For the system operator, this creates the obligation to give the system the proper maintenance, checking and repairs. These regular recurring checks of the electrical system components may only be carried out by an electrical technician.


With ProtectPlus, photovoltaic systems can beat storms, snow, rain, cold, sun and heat for decades.

Throughout their lifespan, photovoltaic systems are exposed to huge loads. Wind and weather take their toll on all the components of the system and lightning and surge voltages pose a major risk to the inverter. ProtectPlus can provide comprehensive protection of the entire system against damaging environmental influences.

Protection against direct lightning strikes
The enormous energy of lightning can destroy PV systems in the blink of an eye, risking the economic viability of the entire system. Longterm monitoring − for example by BLiDS (Siemens lightning and information service, http://blids.de) − document a continuous increase in lightning levels and lightning strikes.

Protection against surge voltage
On the alternating current side, the sensitive inverter is threatened by destructive surge voltages from switching operations and network couplings. Lightning strikes generate dangerous surge voltages in a radius of two kilometres. In the worst-case scenario, these voltage peaks are enough to damage the core of the system.

Protection against environmental factors
Photovoltaic systems are suffering increasingly − meteorological observations show an increase in extreme weather conditions. Only a solidly executed installation can beat rain, snow, heat and cold throughout the lifespan of the system.

Protection against mechanical loads
A PV system is exposed to different mechanical loads. Wind continuously batters all the outdoor system components, whereas snow places huge weights on the whole system. In the case of vertical cable routing, heavy loads occur, which must be supported using an appropriate strain relief.

Protection against the spread of fires
Lightning protection for PV systems has various requirements: the spread of fires in the area of fire protection walls must be prevented, both outside and inside the building. In emergency and escape routes, the cable routing may not bring in any fire loads.

Coordinated protection. The ProtectPlus system kit.

A well-thought-out system for the whole electrical infrastructure of a photovoltaic system – that‘s ProtectPlus. Different components provide comprehensive protection, which allows both the erection engineer and the system operator to sleep in peace.

Solutions for field photovoltaic systems

Today, PV systems in the MW range are a key power supply component. This investment should be protected against theft, against risks from lightning and surge voltages and against damage and failures from incorrect cable routing. OBO offers solutions from external lightning protection systems through to proper cable routing with cable support systems.
