I am trying to come up with a plan for installing an inverter/charger on my 2020 Reflection 303RLS. I have a 270Ah Battle Born GC3 I'd like to put to full use. Hunting around the internet researching adding inverter/chargers for 50Amp RVs I keep coming back to https://www.explorist.life/50a-campe...iring-diagram/ Here they recommend the Magnum MSH3012RV as opposed to the popular Victron Multiplus 3000. My understanding is by placing an inverter/charger in between the 50Amp shore-power and the distribution panel (essentially splicing it in on the existing cable) I will be able to automatically (as a result of the built-in transfer switch) use the entire RV's electrical system on the battery when not on shore-power. This device (as well as the Victron Multiplus) would also provide power-assist from the battery when connected to shore-power sources that are under 50Amp (e.g. 30Amp, 15Amp, etc.).

Then I came across the AM Solar Smart Phase Selector (SPS) and I got confused again: https://amsolar.com/rv-inverter-accessories/50-tsfmb1 Is this for RVs that have two 50Amp cables feeding the panel (one to each side)? Or is this maybe indicating a difference between the Magnum and Victron? Victron has a new Multiplus II (https://www.victronenergy.com/invert...i#pd-nav-image) that supposedly eliminates the need for the SPS and not sure if the Magnum MSH3012RV already supports that.

Thanks in advance,

Jeff
