Just bought a brand new small class C RV and in the process of upgrading its electrical to add four (4) 320 watts @ 40.3V Voc, a 48 volt 200ah LifePo4 battery bank, Quattro 48/3000/35-50/50 120V Inverter/Charger, SmartSolar Charge Controller MPPT 150/45, etc. The Ford E350 chassis is equipped with dual alternators (240 & 157 amps) and we will be upgrading to dual AGM batteries, Optima Red top starting battery and Yellow top deep cycle to handle the 12,000 Lb. winch and air compressor. I know that the Cyrix-Li-CT can handle charging a 12 volt starting battery and 12 volt LifePo4 batteries safely but how do I step up its output to charge the 48 volt battery bank? Or is there a better option?
Thank you in advance.
