FAQs 3

What are the protection measures for the overvoltage of the inverter?

The protection measures for the overvoltage of the inverter vary according to the cause of the overvoltage of the inverter. For the overvoltage phenomenon generated during the parking process, if there is no special requirement for the parking time or position, it can be solved by extending the deceleration time of the inverter or free parking.

Can PV inverters transmit EMI signals in a real-world microgrid?

We successfully validate these consequences on 5 off-the-shelf PV inverters, and even in a real-world microgrid, by transmitting EMI signals at a distance of 100-150cm and a total power within 20W.

Are embedded current sensors vulnerable to electromagnetic interference?

We discover that both the embedded current sensors and voltage sensors are vulnerable to electromagnetic interference (EMI) of 1 GHz or higher, despite electromagnetic compatibility (EMC) countermeasures.
