JJ, When everything is off (not salesmen switch) I have about 4.5 amp draw. I only have 400ah of lithium and the Victron MultiPlus II, 700 W of solar. I full time and it works fine also running my JC converted Norcold 1200 with a 120 volt compressor.
Stephen do you get 35 Psi of boost with your Banks Power Pack?
