Hello, I’m trying to get the Pylontech LV Hub up and running. I connected it according to the instructions at Victron & Pylontech UP2500, US2000(C/D), US3000, US3000C, US5000, US5000B, UF5000, Pelio-L, UP5000, Phantom-S, Force-L1 & L2 [Victron Energy] , but it didn’t work for me. So I first tried …
