Getting ready to install 400 watt Renogy solar panels with 40 amp MPPT controller to our 2007 Endeavor. RV is equipped with factory 8kw Onan Generator with 2000 watt Magnum inverter. Do not plan to change any of that. I have reviewed several wiring diagrams and YouTube videos of proper set up but none address how to deal with potential isolation of solar system from batteries while on shore power or while using generator. Do I need to add a cut off switch to the lead from the solar to the batteries to isolate solar system when on shore power or when running gen set. Renogy has not been too helpful with set up of this nature. Plan is to use solar for battery charging when dry camping in National parks or when restrictions to gen set run times are in place. I am sure someone has dealt with this before.

Hey, guys and gals, I'm new to the motorhome life and recently purchased a 2006 Holiday Rambler Vacationer. I took it on it's 1400 mile maiden voyage a couple of weeks ago. everything worked fine. I do not have any house battery function....and I think it's due to a recent power surge. I had my MH hooked up to a 30A circuit at my home w/o my surge protector hooked up. I was gone for a couple of days and during that time there were a number of electrical storms in the area. The 30 A circuit breaker at my box was tripped, and my MH microwave no longer works (fried?). There is a tripped GFCI switch in the Bathroom that has tripped and cannot be reset. There is no function of any house electrics. The house batteries a brand new, all switches are in their appropriate "ON" positions I would imagine there is a major house circuit breaker that has tripped or failed...any suggestions before I take it to the shop? I've reset all the circuit breakers but can't seem to find the problem... What should be checked at this point or should I just ten it to Camping World or other mechanic to fix the problem? Also, what is the general lifespan of Dometic Rooftop AC units? While on my road trip when both AC units were running it would trip the circuit breakers occasionally, both when running the generator or Hooked up to a 30A shore power box.. Any suggestions on these matters would help. I'm new to this RV life, so be gentle.. Thanks, Kevin

I have a 2003 Itasca Sunrise Motor Home and recently the House Electrical stopped working. Nothing is functioning, I can not turn on the generator, I can not check the levels, refrigerator is not working. This happened one other time and a few days later everything started working. I can start the motor home, and the rear view camera is working. Anyone have any ideas why this is happening?
