About Length of equipotential line of photovoltaic panel
According to DIN EN 62305, the lightning protection system must be erected at a separation distance (s) from the parts of the photovoltaic system. Usually, a separation distance (s) (= safety distance) of 0.5 m to 1 m is sufficient.
According to DIN EN 62305, the lightning protection system must be erected at a separation distance (s) from the parts of the photovoltaic system. Usually, a separation distance (s) (= safety distance) of 0.5 m to 1 m is sufficient.
The PV panels are installed a sufficient distance from the lightning protection system in the protection zone. The photovoltaic system is optimally protected in the event of a lightning strike. The photovoltaic system is integrated into the equipotential bonding.
3. Per the local electrical regulations, determine the length and cross-section of the AC conductor between the end of the IQ Cable and the electrical panel. It is recommended that the voltage drop across these conductors not exceed 1% and that the overall voltage drop in the PV circuit from the point of connection to the most.
(A) Connection of equipotential bonding cable as alternative lightning protection Lightning protection and equipotential bonding • We recommend connecting the rails per module block with a round aluminium wire (≥ 16 mm²). • The connection with lightning protection terminal and aluminium.
Equipotential bonding involves equalising reciprocal voltage, while earthing is intended to dissipate current to earth. The equipotential bonding circuit must be connected to a suitable earthing connection point (as close as possible to the point of entry into the building) that is directly connected to the equipotential bonding

5 FAQs about [Length of equipotential line of photovoltaic panel]
What is isolated LPs & equipotential bonding?
An isolated LPS is achieved when the calculated separation distance between the LPS and the PV system is maintained. Equipotential bonding to electrical earthing system by means of 16mm2 copper conductors. EGI Categories A1 and A2 are exempt from installing any external lightning protection systems.
What is equipotential bonding?
Equipotential bonding to electrical earthing system by means of 16mm2 copper conductors. The bonding of the PV panels is carried out at the internal earth bar only. No Bonding to the LPS is carried out for isolated LPS. An isolated LPS is achieved when the calculated separation distance between the LPS and the PV system is maintained.
How many volts can a PV system run?
PV systems have high dc system voltages up to 1500 volts. Their maximum power point operates at only a few percentiles below the system’s short circuit current. To determine the proper SPD module for the PV system and its installation, you must know: the nominal discharge current.
Should a module frame be included in the equipotential bonding?
ssary, each module frame must be included in the equipotential bonding!Equipotential bonding should ideally be installed in such a way that modules can be removed from the layout in the oten-tial bonding losing its function.Equipotential bonding & earthingIf points are conductively interconnected to v
What happens when a transient overvoltage occurs?
When a transient overvoltage occurs, any inductive voltage drop in the connecting cables can weaken the SPD’s protective effect. This is less likely to happen if the cables are routed to be as short as possible.
