South Africa has one of the highest lightning strike densities in the world and experiences more than 60 thunderstorm days per year with an average of 10 to 15 strikes per square km. You are four times more likely to be killed by lightning in South Africa than anywhere else in the world.

Statistics show 80% of damages on electrical and electronic equipment are directly or indirectly related to lightning and over-voltage surges, while the majority of damages are caused due to indirect lightning strikes nearby (Source: United Business Solutions)

It is a common misunderstanding that a UPS will provide sufficient Lightning and Surge Protection. Unfortunately, this is not always the case. While some UPS’s do provide a degree of isolation and surge filtering, this is mostly for internal protection and rated well below the voltages experienced from lightning strikes.

Solar Electric Africa provides surge protection solutions for AC Power systems, photovoltaic solar systems and telecommunication systems.

AC Power


Equipment connected to Alternating Current (AC) networks can be subjected to a multitude of undesirable electrical phenomena which will disrupt their operation, cause failures, reduce their lifespan, or even destroy them.

The CITEL ranges of surge protector are designed to meet all the protection needs of Low Voltage installations against lightning and industrial surges. The products comply with IEC, UL and environmental standards. Ranges are classified by product Type and their power supply (AC or DC).

Equipment constituting a PV installation (inverters and PV panels) can be subjected to destructive electrical perturbance: transient overvoltages generated by lightning.

CITEL has designed a complete range of Type 1 and Type 2 surge protectors for PV applications that are compliant with the IEC 61643-31 (or EN 50539-11) test standard.
