Solar install, Adventurer 89RB

Thought I'd do a thread that shows my solar install. I have 300w of solar wired in parallel with a 1000W pure sine inverter. I went with Renogy 100w mono panels, no better reason than they fit well on my roof. I am somewhat overpaneled for my modest needs but since I usually have some shade on at least one panel I decided to add an extra.

As you all are aware, finding space for things can be an issue with a truck camper. I was also able to find some unused space behind the kitchen drawers to put the wiring, fuses, shunt for my battery monitor etc. My inverter fits below the lower drawer.

I currently have the epSolar charge controller but I plan to replace it with a MorningStar Ts-mppt. Mppt is probably overkill for me but I wanted to buy something that I could move to another rig if the time comes.



The 3 panels installed on the roof. My first screw up... I got too close to the vent so I could not install a vent cover. Instead I installed the expensive but nice Maxxair fan with integrated cover.



The panels all connect to the combiner box. I decided I didn't want to cut off the OEM MC4 connectors from the panels so I made my combiner box to accept MC4 connections. Coming out of the combiner box is 4awg wire that goes into the camper via the fridge vent.



I couldn't see an easy way to run the wire beside or under the fridge so I ran it through the wall and into the compartment under the dinette seat where the water heater lives.



The wiring was then ran across and following the same holes as the water lines into the space below the cabover step. Then the wire was ran under the step over to the cavity under the sink.



This is a pic with the drawers removed, the sink is to the upper right and cabover step to far right.



This is where I found some space to mount shunt, circuit breakers etc. that hole was not there from factory so i cut that out to get access to the empty space. It doesn't seem to have weakened the drawer mounts at all. That piece of wood in the back is built as an L and is attached to the battery box. To the right the wires are coming from a battery disconnect switch.



Wiring from panels comes to the disconnect switch and then on to the charge controller.

I've been quite happy with the system. I still carry my generator with me but with driving and solar charging I never had to start it this season. We aren't big power users our biggest draw is the furnace and running our Keurig to make coffee in the morning and sometimes the toaster.

I know the wiring is messy, It will be cleaned up when I change controllers.

If anyone spots any concerns with my install please let me know.

I'd also like to thank many of the members of the forum especially in the tech section for answering my questions. I was a complete newbie at this when I started so I had a lot to learn... and still do.
  • Looks fine, but what's all the junky white stuff on your roof?
  • Roof is dirty, snow :( I think I am also the worst person every with a Caulk gun... I get it everywhere. I also have some spots I need to clean up where I pulled up some eternabond and the adhesive was left behind.
  • Nice work. I especially like the 4-gauge wire as this will get you every drop of milliamps. It looks like the inverter found a good home too.
    Does that inverter make much noise? Fan?
    Free energy forever!
  • Looks good! Looks like you are going to have some great times ahead, being unplugged. Goop is good, it does not need to look good to work well. One of the items you might consider is Catastrophic Fuses to protect your invertor and battery bank. Also, a little info on your battery bank and photos would be good too.

    Thanks for putting this together and for others to benefit from your project, too.

  • I have a circuit breaker between the controller and batteries, also between the batteries and inverter. i just have the disconnect between panels and controller, by my calculations I don't need fuses/CB there unless I had 4 panels. I have a catastrophic terminal mount fuse on the battery connection itself. I used Blue Sea stuff all around.

    Battery bank is nothing special, just two grp 27 batteries, they are the largest that will fit in my battery box unless I mount them in the truck. At this point these batteries provide us with enough capacity.

    The inverter does have a fan and a remote switch, we pull about 85amps when making coffee so the fan does run then but I think the coffee maker is still louder.
  • Great write up and install, congratulations.

    You are going to really love the advantages of Solar.

    We did a 8 week trip and almost 10,000 miles up to Alaska Prudhoe Bay and did not plug in to shore power. Other cross country trips the same, no shore power. When It was 20 deg and sitting in a CG in Midland Texas 2 years ago we did take advantage of the shore power and our little 1500 watt heater..hahahaaa.
