I use the relay on a Victron Cerbo GX unit to control an Auto-Relay (https://wildebus.com/product/was-inverter-mains-automatic-transfer-switch-systems/).
I too love the French, I used to say I was European but I suppose now I am English if I need a nationality. France is incredibly accommodating to travel weary bikers either on your own or in groups. You could even pull the bike up outside and walk in to the casino at Monte Carlo in your leathers back in the late 80’s early 90’s. Try that in the U.K. lolAs a Scot I love the French.
