There are two types of solar charge controllers. volt sprinter capacity power system van kit views 2007 We use a small electric kettle and a 4 gallon electric hot water tank. Unless youre an electrician, all this talk of van electrical systems like batteries, inverters, solar panels, wire, and more may have your head spinning. But, we ended up sending one back after changing the layout of the roof rack. Kristen did not install her solar system herself but if you want to try doing it yourself Im sure you can find some helpful DIY info out there through a google search You can read all about Kristens solar setup here and learn more in the accompanying video as well: https://bearfoottheory.com/sprinter-van-solar-panels-batteries/, Hi Kristen, We chose the Renogy 2000W 12V Pure Sine Wave Inverter for our AC power needs. A couple questions for you: did you do the solar install yourself? We purchased a hydraulic wire crimper, quality terminals, and good-quality adhesive heat shrink tubing. sprinter opener ador croco These are just some of the questions to ask yourself when determining how much power you want, and ultimately, how big of a battery bank youll need: There isnt a one size fits all approach to van life, but together, were going to explore the foundational pieces necessary to determine your priorities to help you plan for your ideal electrical system.

If you want solar panels on your roof, you need a charge controller to control the charge from your solar into your batteries. My question is this.Im looking at some of the reviews of solar power stations, especially ones that can be charged through the 12v van battery while driving (would this be a charging relay?). Some newer devices wont operate well on modified sine inverters either, so its important to research the exact appliances you plan to use and what the manufacturer recommends. What a great Article, very informative, well written. Remember that the longer the wire, the more resistance along the path to and from the battery. Theyre more expensive but will provide a steady flow of energy. Shore power is a viable option if you plan to stay in full-service campgrounds with plug-ins. Why did Mercedes put the trailer wiring box so close to the Sprinters receiver hitch mount? There are several mounting options, but you will probablyeither use a roof rack to mount them, or make use of the roof channels (if your van has them) to slide in little fixings for the edges of the panel. After considering the space we had left on the roof, we purchased two 100 watt solar panels from Renogy. Hey there! Be careful though inverters are very power-hungry. Another major downside of a generator is the noise factor. Making a clean electrical system in a van is not trivial. We provide consultation and wiring schematics complete with materials and sourcing. The first is called PWM or Pulse Width Modulation. To wire up the big power inverter safely to the battery, we ran 1 AWG cable with fuses. But where do you start? We needed to bring power to these componentsand fight the temptation to install the track system and CVG Douglas Fir cladding. We wouldnt recommend the factory auxiliary batteryas the basis for a conversion. Generators can be loud, impacting your ability to enjoy the sounds of nature. There are also different types of batteries. Theyre built to handle consistent vibrations and changing temperatures. Pick fuse values based on the wire amperage capacity, AKA amapacity. AKA, buy extra wire and crimps. Do not underestimate how much time wiring can take. An automatic charging relay is a small device that attaches to the vehicles alternator. Now 15 years later, prioritizing that critical connection with nature continues to improve my life. Were convinced that the lifetime cost and convenience of lithium isa better proposition than using lead-acid batteries. The last thing you want is a fatigue crack from a 120V solid core cable in the wall.

Add shut off switches to mains, auxiliary, and anything that draws power. UPDATE: Dont want to tackle this yourself? Protect your wiring from chafing or use power cord wire, also known as. There are products out there that will maintain temperature, so make sure to look into this if you decide to go the lithium route. We use the van to get out into nature, so we hate camping near people who run their generators. Another 100Ah battery will be purchased when funds allow which will be installed in parallel. Basically, a 100Ah Li-ion battery is the equivalent of two AGMs, and lasts longer. While the solar panels convert sunlight into electricity, that electricity voltage and current isnt suitable for batteries, so thats where the charge controller comes in. Renogys options, albeit good stuff, are a bit limited due to being designed in size to allow for UPS shipping.

In this post we share our electrical diagram for our Sprinter van and a brief explanation on why we chose what we did. It relies on the van being driven regularly so that the small starter battery can be recharged. We went this route for a few reasons: For the 12V DC circuit, we added up the loads from the fridge and the cabin heater to come, and also the LEDs and other components that we might run to give a margin of error.
