After a LOM , unit has difficulty reconnecting .I have read on this forum that a firmware update, from 466 onwards ( 456 installed ) overcomes this issue - externally connected neutrals allowed .Only other option , momentarily remove load via a contactor / programable relay, to allow grid reconnection , then return load connection - clumsy but , better than ‘ shut down’
Any comments on both of above would be most appreciated. I have never done a firmware update before , will save present settings . And any known issues with firmware 471.
