Yes, if there is no load on the string there wont be an arc. If there is a normal one string load like 7 amps you should use rubber gloves and pull it apart fast so as not burn the connector.
Hauwei Gave us an RMA for internal fault. We replace MC4 connectors on the home run strings but those panel mount connectors built in to the inverters would be very hard to replace. Power boards block access to the back of those.
Thanks for the awesome video. The DC breaker is tripping. Is it safe to disconnect the PV cable connector from the DC Disconnect box on a Sunny day?

Nice
Bad connector, replace MC4 on input side
