    You're welcome. I ran a remote control panel for the controller the other day. Whoever designed our RV was an idiot. LOL

    Anyway, we're off on a four state adventure in a couple of hours. Sisters OR to visit a good friends ranch, Grand Teton, WY, Sand Point, ID and then spending a week in Kettle Falls, WA at a National Recreation Area. All dry camping.
    Talk with y'all later!

    I will report back in a couple of weeks. So far they are maintaing the battery bank charge at 100 percent. We'll see when we start putting some loads on them. Fridge controller, hot water heater, lights, and a couple of other parasitic drains.

    We do not run a dc/ac inverter.

    Some people will run the cables down the gray water vent tube. Drilling a hole in the top of the tube right under the cap and drilling a hole inside the coach somewhere above the tank water level and pulling the cables out there. Dicor or ProFlex the bejeesus out of the holes and you should be good to go.

    I would recommend an a true MPPT 4 stage type charge controller versus a PWM type(older tech). They are much more efficient in converting the panel amperage to battery charge amperage. 97 percent conversion efficiency. Good luck if you decide to go solar.
    I looked and the gray water vent comes right down the center where the control panel is located. I think this is going to work out perfectly, thanks for the tip.

Lucky and knocking on all wood I can find!!!
    Crikey!! That is a lot of damage. I can't believe the hail put holes right through them.

I can not run the wires down the refrigerator vent since mine is in a slide so I have to figure out another way to get them down inside. Not sure about drilling holes but the Dicor seems pretty good at sealing.

    Cabled them up to a new MPPT 20amp charge controller and interfaced it to the battery bank today.


    Full sunlight right now and the panels are pushing out 20.8vdc at ~12 amps.

    No more long runs of the genset during extended off-grid stays to charge the batteries. Yay

    See! I'm green.

    I am looking forward to hearing how they work out on your two week trip.
    I have a toy hauler that I use for my photography business. I use it about 20 weeks a year.
    Almost all of the facilities where I set up have adequate RV hookups, but on out of state runs, I have layovers where there may be nothing.

    Thanks.

    We're going for an extended dry camp outing in 2 weeks. Looking forward to not hearing the generator running.

    You might want to fab up a protective cover and keep it close by. Family history has shown, moderate Hail can destroy solar panels.
    Just food for thought

    I'm thinking about some sort of waterproof padded cover.

    I installed a Mighty Mule electric gate operator on the front gate that we use daily for vehicle traffic about three years ago. I mounted a lawn tractor battery to power it and a 5 watt solar panel to keep the battery charged. Regardless how many times we cycle the gate, even during cloudy days, the battery is always hot and the gate always swings open.
    The new mono panels are light years ahead of the older poly ones. At first light this morning mine were putting out 14v ! Amazing.

    2 years ago I purchased a smaller 50 watt mono panel that I would tug along when we camped--manually set it up and run cable. I was so impressed with its output I upgraded to larger panels.

    Holy cow! I'm sorry to hear about your neighbors RV.

    I hate hail. In 1998 I had just purchased a new car and decided to park it outside in the open parking lot at work. I usually parked in the covered parking garage. It was right next to the building entryway and I am generally lazy, . 2 hours later we got pummeled by hail.

    My white car now looked like a big golf ball. It even had huge dents on the sides because some of the hail ricocheted off the cars next to me. 2 days old and a total insurance company loss.

    Two weeks ago my neighbor did the Z-Man Solar Panel install to do basically the same thing. Told him it would be great once we get out of the Texas rainy season, kinda joking with him. He said its going out next to my Carport today..... well last night was not good.... he said there's not much left!! He was in the direct path of a Baseball size hail storm that cleaned the roof of his Toy Hauler , all Vents are gone, Plastic AC Shroud is 90% gone, the Wingard Satellite is just beat to crap, the Solar panels are still in their frames but destroyed, water poured thru all the vent openings and 6 of the windows are broken out..... sounds like insurance time...... and its still pouring and not suppost to quit today. Have even lost my Forum Satellite connection... and it doesn't look like the sun is going to shine today! Every lake and empty stock tank is now full or close to it and many overflowing!! Guess we're no longer in a drought..... He's a little afraid to get on the trailer roof...... Luckily before we went to bed I got everything undercover and we have a Steel Panel roof on the house so it sometimes get noisey but that roof sure makes a lot of crushed ice!!! Hail just blows up on impact.....

    A little. We were keeping the RV plugged into a 110vac outlet at home to keep the batteries charged.
    The savings for us in this application is not running the generator as frequently or at all when we're away from the power grid
