How to protect an SMA inverter from overvoltage?
If you wish to protect an SMA inverter against impacting overvoltages, an SPD type II is sufficient. If lightning partial currents are expected, an SPD type I with connected SPD type II should be used. For inverters with one MPP tracker, the strings are combined before the inverter and connected to the SPD(s) at the point of interconnection.
Can overvoltages be neutralized with a protective circuit?
This article explains how overvoltages can be neutralized with a protective circuit. Overvoltages can be caused, for example, by the rapid switching off of a high load in a power distribution system. Surge protection is recommended to protect other loads that are connected to the same power supply.
Why is the protection level at the inverter increased?
In addition, the protection level at the inverter is increased if the overvoltage occurs at one of the other strings. When excessive voltage is applied, voltage falls via the cable inductance. If the arrangement is not ideal, the protection level at the inverter is increased (see Fig. 6).
What is overvoltage protection?
Overvoltage protection serves to prevent damage to electrical and electronic devices as a result of excessive voltages. Overvoltage protection devices (surge protection devices, or SPD for short) generate equipotential bonding between the connected conductors when excessive voltage is applied.
