The connection of the PV to low voltages should be protected. Surge protectors are designed to protect against the overvoltages caused by lighting or from external AC sources. A diesel generator or the national grid may also cause voltage disturbances that will damage the electronics of the inverter.
Technology: High energy varistor with thermal fuse.
The surge is also essential for domestic consumer units and should be installed before the main RCD breaker. According to the 18th Edition of Wiring Regulation, a surge protection device should be fitted where the overvoltage may cause a failure.
