I have had 2 Multiplus II working in spit phase 180 for almost 10 months. Recently I bondocked for a couple of days then when I got to a rv park and hooked up the Multiplus's wouldnt connect to shore power but still work fine on inverter and my solar is still recharging batteries. I have a cerbo and overrule by remote is switched on but dont see any reason the cerbo would not allow the multis to pass thru. I can see my incoming power of 124 both legs at the multiplus and on the cerbo. but no connection i checked all the settings in the multis with the dongle and have changed several settings to no avail. I want to ask if anyone has a suggestion and if the i could of changed the communication mode in the cerbo by accident? would that cause my problem Thanks
