The factory package is a joke and poorly executed. You will be better off doing it yourself aftermarket.

It will be next spring/summer before we do anything but I have been thinking about solar. I am pretty sure my original batteries will be spent by that time after another winter of just one 2 week usage so it be a good time to do it.
Are there good write-ups on what you need to be able to run 1 AC unit, along with the big drain appliances, for a unit like a 375RES? Like someone mentioned above I think the design of a system so it can be expanded as needed is critical.
Thanks for any help in sorting this out!Tim & Sue..with pups Iris and Sam

On all my RV's I have preferred to do the installs myself as in my experience the factory and/or dealer installs do a poor job in terms of maximizing efficiency and choice of components are not always the best choice. Not everyone has the electrical background to design and install a solar system, I understand that, in such cases it would be better to go to a quality solar installer.

Running an AC for any extended period of time on a solar/inverter setup is not feasible. I have a $20k system I designed and installed myself very well and I can only run the AC for a handful of hours before I am low batteries unless I have absolutely perfect sun conditions (which happen for about 1-2 hours a year).
You have to think about it in a few ways:
-What am I trying to run, how much power do those require (dictates size of inverter)
-How long do I want those things to be able to run, how low am I ok with my batteries going (dictates how large of a battery bank is needed)
-How much total power do I plan to use in a day, how much do I need to recover using solar (dictates how much solar you need to recover energy used)
A good rule of thumb seems to be to plan on about 75% of the rated panel output for sizing. As an example, I have a 2880w array on my roof, I typically see around 1800-2200w of actual output for a couple hours during peak of the day. I get lower output before and after peak. I would say I was generally recovering 10-13 kWh of energy a day in the summer with my panels flat mounted and no shade. If I had the RV pointing E-W and tilted my panels towards the south I could improve that but I am in a high wind area so the tilting is not an option really.2019 GMC Sierra 3500HD Denali Diesel DRW (Crew Cab | 8 Ft bed | OEM Puck System | Curt Gooseneck Ball for OEM Puck | Timbrens on rear axle)
