surges in the PV system can cause damages to the PV modules and inverters, care must be taken to ensure that proper lightning protection is provided for the system and entire structure. The inverters should be protected by appropriately rated surge arrestors on the DC side. Structures and module frames must be properly grounded.

How Far Can Solar Panels Be from the Inverter? A Guide to

Ideally, solar panels should be as close to the inverter and charge controller as possible, with recommendations suggesting a distance of 50 feet or less to keep energy losses low. The distance between panels and the inverter can impact system efficiency and output due to factors such as wire length, temperature, and energy loss during transport.

SIZING THE MAXIMUM DC VOLTAGE OF PV SYSTEMS

If this voltage gets exceeded, damage or even worse harm can result. New technologies established a new standard, to build PV systems with voltages up to 1000V (for special purposes in big PV power plants with central inverter topology even 1500V are used). This makes sense by causing lower losses (power / energy, voltage-drop) and gaining
