We also have an air compressor for inflating bike and van tires. You are choosing wiring based on a function of voltage and amperage, which is vastly different in 120V and 12V systems. If AGM batteries are properly used and well taken care of, they should last a long time. We chose Lithium Ion Batteries from Renogy because of the great customer service, decent price with discounts and long life of Lithium Ion Phosphate. Well talk more about this option later on. Heres a recap of our demo-day, cleaning, and preparing the van to build. In the future, I would consider lithium as a way to save space and weight, but Id need to take extra precautions with temperature control since we use our van on ski trips. Opting for a solar power system is a more eco-friendly option, but it does have a heftier initial investment. The reason we chose a 250A fuse was that our batteries can normally supply 200A of 12v current, so you want a fuse that allows for the max electric current but will break if it goes much further. We added up all of the load requirementsand carefully planned out what components we might actually have powered up at any given timeto calculate an amperage draw. SE Portland OR, For van related inquiries visit They are significantly less expensive than lithium batteries, especially since lithium batteries are newer on the market. We purchased a hydraulic wire crimper, quality terminals, and good-quality adhesive heat shrink tubing. sprinter wiring dodge The factory auxiliary battery is not good enough for a van you want to camp in.
Its also a really inefficient way to charge a lead-acid battery, because the battery cant take all the power that the generator provides. One caveat is youve got to keep gas stored for the generator, so thats something to consider when planning your build. battery inverter cabinet power hookup sprinter watt van 1500 charger solar electrical shore conversion finished instagram trailer The other type of solar charge controller is called MPPT or Maximum Power Point Tracking.
I would have added more switches to the location of the appliance, as pulling fuses to turn off stuff is a real PITA. We chose the Renogy 2000W 12V Pure Sine Wave Inverter for our AC power needs. Luckily, solar controllers are designed to take the varying voltage and currentand turn it into a steady output.

If it gets down to 12, youll need to charge your batteries as soon as possible as anything lower will start to degrade the battery. power sprinter volt capacity system A charge controller also protects your batteries from overcharging, improving their longevity. To prevent any further damage, we flipped the main switch so no more power could be drawn by the charge controller or 12v fuse box. Li-ion batteries are less than 1/4 the weight per usable Ah. Shore power is a viable option if you plan to stay in full-service campgrounds with plug-ins. The generator and fuel tanks are heavy and take up a fair amount of room, so youll need to have a dedicated space for these. A Li-ion battery can be completely discharged well over 1500 times vs 500 times for an AGM unit. I found myself plugging in more or using the vans alternator to top off my batteries and for that reason, I decided to size everything up in my second van. Because of this, its important to understand the basic layout of a wiring diagram. Another major downside of a generator is the noise factor. We added a system monitor to keep track of the battery and solar system status at all times. Before we start building, we have to prepare the van and address any interior rust issues. We had to determine the loads the system would need to support. Effective and safe. We first looked at Gel or AGM deep cycle batteries that do not need to be vented to the outside. This switch is a very important safety measure to be able to turn off all the power coming from your batteries and going to your components. thanks Khalden, Hi, Hi Paige, sorry for the delay in getting back to you! sprinter opener ador croco towbar socket sprinter towing inst volt sprinter capacity power system van kit views 2007 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,
