Hi, I have just installed the new Orion Xs on my Motorhome. It's a 2015 3.0 Ducato base. I have 3 x 100amp Renogy Smart Lithium batteries as leisure. I am using the default settings, but my Amps are fluctuating between 0 and 25 amps on both the input and output every few seconds. On the graphs they match perfectly, I have isolated the original charging system. Can anyone offer any suggestions?
