Surge protection for PV systems is an important topic that needs to be considered during installation in order to protect buildings and systems from damage caused by lightning strikes and surges. Our portfolio offers extensive options for protecting buildings from damage in accordance with EN 51643-32. At Intersolar, we will be demonstrating how additional functions, such as emergency shutdown in the event of fire, can be integrated here.
The compact PV combiner box PV Inline with SPD Type I+II is used in
rooftop PV installations. It protects the PV system from overvoltages, including lightning strikes. In the event of an overvoltage, it creates a ground connection. Thanks to its space-saving design, the surge protection device (SPD) is particularly suitable for confined spaces. It can be integrated into cable channels or mounted behind PV modules.
Building insurers and local fire brigades are increasingly demanding that rooftop photovoltaic systems switch off automatically in the event of a fire. This switch-off device must be placed where the string cables enter the building. Automatic switch-off occurs when the fire brigade switches off the building's power supply. When the power supply is restored, the PV Next Fireman Switch automatically reconnects the PV strings.
The monitoring of utility-scale PV systems at string level is crucial for detecting yield losses at an early stage and optimising the system's performance. By analysing individual strings in detail, defects, dirt or shading can be quickly identified and resolved. This maximises the efficiency of both new and existing systems and ensures high profitability in the long term. State-of-the-art monitoring technologies help to ensure reliable operation and minimise maintenance costs.
Our PV retrofit combiner boxes with wireless LoRaWAN communications help O&M personnel to allocate and isolate any field problem in a few minutes. The product features LoRaWAN communication, enabling quick on-site fault diagnosis and providing string-level data without additional cabling or trenching.
PV systems should deliver optimum performance. In order to use as many plant resources as possible for energy generation, regular monitoring of weather parameters is crucial. Our PV Weather Boxes provide reliable information on all important weather parameters. Values such as temperature, irradiance, wind speed and direction, precipitation, relative humidity, and much more can be permanently recorded.
