I did not see a power requirement in kWh for a day or a max power requirement in kW.Greetings,
I am in the information gathering stage of assembling a 50 Amp Off The Grid Boondocking Solar System for my new 45 foot Keystone Fuzion 429 Toy Hauler.
I've spent weeks online trying to absorb all of the information I can while trying not to get steered in the wrong direction.
I am aware that this system I desire is going to come with a hefty price tag.
So far, I think I am set on going all Victron components with the exception of solar panels and batteries, in which I'm leaning toward Battleborn.
As far as Victron componentry, a rough draft would be the 50A Multiplus II Inverter, 2-150/100 MPPT's, Cerbo GX, Lynx, Smartshunt, Display, etc., with all the necessary breakers and fuses, correct wire size, 10-200w panels on the roof, and 10 battle born lithium batteries. For voltage, a 24 volt solar to 12 volt battery bank should be sufficient I believe.
Being a jack of all trades and able to install my own system, I have never delved into solar before now;
however, I do understand the principles of AC, DC, Etc.
This has led me to this thread, as I would really appreciate some feedback and assistance on this endeavor. I would need help on routing and schematic diagrams here. I keep seeing these wonderful layout diagrams depicting Victron and related componentry and how it all connects all over the place.
Is there an app or tool out there for configuring solar systems that you guys are using? Boy, that would be helpful.
So what say you...? Anyone out there care to share their expertise on designing a very robust solar system on a big toy hauler?
Thanks in advance.

I don’t think anyone has made any mention of the amount of solar panels needed. Please remember if both 50 amp legs of the panel are active, that can pull 10 kw. Running two ACs and an electric water heater will pull 5 kw. This would be numbers from the battery which does include 15% inverter losses.
Solar panel put out around 180 watts per meter squared. I have 1650 watts on top on my 35’ travel trailer. I also have 900 watts I put out on the ground. With that I get 2100 watts total in March at the equinox. If I put solar panels on every square inch of my roof including over the ACs, I would have 3 kw of panels up there.
If you’re interested, my build is listed in my signature block.
IMO, if you are asking for a single leg of 50 amp input, $15k may be doable, but if you are looking for both legs at 50 amps, I don’t see this being possible.
