RV solar design input needed
Planning to do a major renovation on our 1996 Tiffin Allegro Bus. We currently have only two house batteries and no inverter in our system. Planning to start with six 110W solar panels with room for more. I'll be using flexible solar panels due to weight concerns. The bus has a max weight of 26000 and I don't want to add too much extra. Glass to flexible weight difference is substantial. So with the possibility of additional solar, I am starting with the Victron 150/85 rather than building for just the 660W of solar power. Thinking of breaking up the 6 panels into two groups, with each run in series which will bring the 3 to 54V and 6.11A and then combining those two sets of three into a parallel connection to bring power up to 108V and 12.22A to charge 6 100Ah house batteries. (Hoping for lithium, but may start with lead acid due to cost)
Shore power and generator will be on an automatic generator start triggered off of the battery monitor. Haven't decided on what to use with that setup so suggestions would be appreciated. Power from Onan 7500 generator and shore power will be brought into the Victron MultiPlus 12v/3000W Inverter/Charger. Benefit of the Victron is that it can combine power from house batteries and AC power to service the bus.
I just was hoping to get thoughts and ideas. Not really sure about fuse sizes so that is a critical part of system that need review. I'm not an electrician and have been reading the details on the Victron website and seem to be getting more, rather than less confused. Hoping to hear from some who have accomplished a solar upgrade with addition of inverter/charger into their system. Thanks for any help you can provide.
