I am working on my third solar install as we just purchased our new 5th wheel. We had 3-100 Ah Battle Borne lithium batteries in our previous rig and will be adding 4 more in the next week or so for a total of 700 Ah. I have on order the Victron battery monitor which I will be installing at the same time I install our batteries. I am leaning towards a Victron MPPT charge controller and somewhere between 900 & 1100 watts of solar using high voltage panels, just have not decided on which ones yet. For an inverter, I was considering the Magnum Energy Hybrid 3000 watt pure sine wave inverter, but I am now leaning towards the Victron MultiPlus 3000 watt pure sine wave inverter, simply because the Victron allows for customized charging settings, so I can match the settings Battle Born indicates. This will be beneficial when plugged in to shore power.
