Prior to April of 2018, our only boondocking experience in the initial 20 months of taking a trip the nation in our recreational vehicle, was 3 nights at a state park in Rhode Island, and one night at a truck stop car parking whole lot in Laramie Wyoming. The weekend break invested in George Washington State Park near Providence Rhode Island was spent outside, playing in a lake, appreciating the cozy summertime weather, and our only electrical requirements were for the lights.
The furnace attracts a great deal of energy, and running all evening would certainly eliminate any solitary 12v battery in a matter of hours. That wasn't the minute we decided to obtain even more batteries or anything like that, it was just our only experience with outdoor camping off grid for any amount of time with our Cyclone.
Windy Nation appeared to have the marketplace cornered on Amazon recreational vehicle Solar, so I went with them. To get the power out of the batteries, I added 2 standalone electrical outlets directly to the inverter, one in the kitchen for our Instant Pot, and the other in a very easy place to accessibility for billing and whatever else we needed it for.
Despite the fact that the sun never ever sets in Alaska, we definitely fought with the 3 panels on the roof since it was cloudy and over cast a lot of the time. Thankfully we can charge the batteries a couple of different methods: Solar panels, when the sunlight take place to be out Alternator, when the motorhome's engine was running With the on board generator We traveled in the Summertime Home from April 15th to August 25th and in those 4 months I most definitely found out a great deal concerning powering a motor home solar off the grid.
Possibly an added battery (and much better batteries), another panel or 2, and be much more conscious of the dimension and length of electrical wiring I made use of for the numerous connections throughout the system. Overall it was a fantastic affordable option that functioned. The main takeaway from that experience was we did NOT intend to depend on 2 separated electrical outlets; we wanted our RV to work the very same whether it was plugged in or otherwise.
This is a bunny hole like you have actually never seen! There are so several methods to skin this pet cat that my head was rotating. I was looking into panels, inverters, inverter/chargers, charge controllers, batteries, wiring, breakers, battery monitors, etc. There is a riches of information around, however it was done in some international language that spoke in terms of watts, ohms, volts, amps, scale circuitry, crossbreed, help, bluetooth, Wi-Fi, and the list continues! We bought a Kill-a-watt electricity usage display, began gauging our power usage and completed a power Audit.
We have the ability very quickly to make use of a lot of electricity. When believing with the procedure, and what we intended to achieve with the system, I kept reflecting to our solar mission statement from the Summer House, we desired our recreational vehicle to function the same whether it was connected in or not! My please note: I am wonderful with DC electrical systems, but know only sufficient regarding AC systems to be unsafe.
This blog is NOT suggested to be an outright resource for powering your motor home, but more to document our build and trip to being power independent. I mentioned above, our 40' toy hauler fifth wheel came from the factory with a solitary 12 volt battery. We had actually changed it in the previous year, and honestly had not truly used it for much considering that we were always connected in.
With that being stated, our 50 amp Motor home has 2 x 120-volt hotlines going right into the Recreational vehicle's major Air conditioner distribution panel. It feeds 120 volts of Air conditioner to the important circuits of the Recreational vehicle.
Victron Multiplus Inverter/Charger Much of the installs that I was following, all appeared to return to a number of different makers, Magnum and Victron seemed to be leading the method. Several of my buddies were using Victron components with a great deal of success and high appreciation, so I chose their equipment for the core of the system.
We will certainly get to that later! Lucky for me, a friend of ours is a Victron Dealer, and I was able to get a bargain on the meat and potatoes of the system. 2 x Victron 12/3000/120 -50 Multiplus Inverter/Chargers These are real sine wave inverter/chargers, and fill in the existing converter battery charger already in the motor home.
Yet space was a premium up there, and the inverters had certain air gap needs. The Generator has a sheet metal shroud separating it from the remainder of the area, so I opted to reduce that shroud down 6" to obtain the additional area I needed. I cut around the shadow, dropped it down, and put pop rivets to hold it in position.
According to the Victron Handbook, the inverters can be placed flat or vertically, so I chose to place them flat on their sides on the wall. In doing this, I met every one of the needed air gaps. The initial wall was only" fragment board, so to sustain the 70lbs that each of the inverters weigh, I added a piece of" plywood across the rear of the wall surface behind them.
Given that we are talking solar system, of training course we needed solar panels. There are several various alternatives out there for solar panels; in the end I selected to go with Continual Resources for a couple of different factors.
One of my friends has one that was split throughout installation, and it still functioned well! Something I liked concerning the specific panels I went with is that I can get the exact same specifications in a square or rectangular panel. Ultimately, I selected all rectangular shapes, however had I wanted to (or when I desire to) add more panels, I can obtain the different forms and make better use my roof covering room.
We hadn't slanted as soon as, and 1 set of the turning braces set you back greater than the total collection of the Z braces. So I went budget on the placing brackets. A friend of mine that assisted me set up the majority of the system educated me a fantastic method to mount the panels.
We pierced pilot holes, placed dicor in the hole, screwed them down and after that covered the base of the bracket and bordering roof with dicor. The eternabond tape provided it an included layer of water seal, and shielded the rubber from being tore if the metal Z bracket took place to shake or relocate whatsoever.
It's crucial to have a plan in position for the wiring. When you start dealing with reducing and crimping lugs onto the cable televisions, it obtains extremely costly, and you do NOT intend to need to crimp, reduce, and crimp again. That will certainly cost you $5 or more for each time you overlook cord size and waste a cable lug.
Since I was installing 2 inverters and 2 cost controllers, it was very important to keep those 2 systems different. I utilized red and blue wire labels to determine electrical wiring so I would not obtain them confused. I likewise applied the same red and blue sticker labels on the components themselves to assist keep points straight.
Get on your own a great set of cutters and a pole dancer for heavy scale electrical wiring. Hydraulic kinking tool. I was lucky sufficient to have a friend helping me with the majority of the installment that had this kinking device, and when he left, I battled to locate a crimping device to end up the job that really did not entail simply beating the lugs with a hammer.
Invest the $50 on Amazon for the crimper. MC4 adapter crimper/tool package was likewise excellent to have. I got it off Amazon for less than $30, and it made making my connections between the panels a lot easier. Digital Multi Meter. It doesn't have to be super fancy, however the capability to determine resistance/continuity and both a/c and DC voltage is essential.
From Home Depot I obtained a water resistant electrical box concerning 8"x8"x6". I drilled 5 openings into the box: 4 x Tiny openings, one each for wiring coming from the panels with climate evidence fits to keep the elements out 1" hole in the lower leading the cords through the roofing system right into the walls of the RV Inside the box the 10 AWG cables from the panels were spliced onto 6 AWG cables for its journey through the Motor home to the solar fee controllers Victron components all function extremely well together and share info.
Along with every one of this electrical wiring, the Inverters and the Battery display featured voltage sense and temperature feeling wires that had to be connected to the battery financial institution accordingly. Let's start with the solar circuit. I am running 6 x 200 watt panels configured into 2 x 3 panel legs wired in series.
I found it more inexpensive to run 2 separate smaller controllers than 1 bigger controller efficient in dealing with the quantity of power originating from the panels. Furthermore, given that the 2 strings are running independent of each other, if there is color or lack of angle to the sunlight on 1 of the 2 strings, it will certainly not hinder the energy manufacturing of the various other string.
Keep in mind; as soon as the panels remain in sunshine, they are producing electricity, so I made use of the breaker in this setting to give me the ability to isolate them entirely from the rest of the system. From there the electrical wiring runs into the solar charge controllers in the front area near the battery bank.
Once more the point is to not just safeguard, yet to offer me an area to separate the system if demand be. The last leg of wiring in the solar circuit goes from the circuit breakers right into the positive and unfavorable busbars that are straight connected right into the battery financial institution. Let's keep going with the DC (12 volt) system.
A DC system is a lot more comparable to the kind of electrical system discovered in an auto. The motor home's 12 volt system has its own security and control in location, so I did not change it any type of way; I merely powered it from the favorable and negative busbars from the battery financial institution.
This part of the circuit can run exceptionally high quantities of power relying on what you are powering, so this needs significant defense. From the Battery Bank, I ran big 4/o electrical wiring into a 400 amp fuse. This catastrophic failure fuse is meant to shield the wiring in between the inverters and the battery financial institution.
