Whether or not you reside on the street full-time or part-time, there’ll seemingly come a day when you could preserve battery energy in your camper van. This can be since you’re tenting off-grid on dispersed land for days at a time, or maybe you’re staying in a campground or going to a competition that doesn’t provide electrical hookups to plug into shore energy.
In my first Sprinter van, I realized concerning the significance of conserving my battery energy the arduous means after fully depleting my batteries whereas touring on the Olympic Peninsula. I’ll preface this with the truth that it wasn’t all my fault. My van had some wiring points and my photo voltaic panels weren’t charging the batteries correctly, and I additionally didn’t obtain any kind of coaching from my van builder on the right way to monitor my system.
Both means, I used an excessive amount of energy and my batteries went lifeless. I spotted my drawback when my freezer starter defrosting and melting ice water leaked out of my fridge throughout my van. Not solely did nothing in my van work, however drawing my batteries down so low brought on irreparable harm, and the batteries had to get replaced.
This was a tricky and costly lesson throughout my first few weeks of van life and after that, I always pressured about ensuring I didn’t make the identical mistake once more.
My battery financial institution wasn’t all that massive, and I additionally didn’t have sufficient photo voltaic on the roof to ever be carefree about my energy consumption. Winter was notably difficult with much less solar and the necessity to run my heater. Throughout this time, I needed to be very cautious to not deplete my batteries and realized some useful methods for conserving my energy.
Now that I’ve lithium batteries (the Lithionics system) in my present Sprinter van, I don’t have to fret about operating out of energy anymore. On a 5 week journey, my batteries by no means dropped under 75% capability!
Though it’s not as massive of a priority for me now, I nonetheless keep in mind what it’s wish to be nervous about operating out of battery energy whereas tenting off-grid. I do know that energy consumption is a typical concern for brand new van lifers, so on this submit, you’ll discover some useful ideas I’ve realized through the years for conserving battery energy in your camper van so you may keep off-grid longer.

1-on-1 Van Life Teaching
Able to recover from your evaluation paralysis and put your van life goals into motion? Let’s make it occur collectively. E-book a 1-on-1 van life teaching name now and take step one in direction of a lifetime of journey, freedom, and unforgettable experiences.
1. Observe your battery utilization
Earlier than you may start to preserve battery energy in your camper van, you need to think about the way you’re utilizing your battery at present. Which units or home equipment are you utilizing that draw energy, how usually are you utilizing them, and the way a lot energy do they draw?
Listed below are some frequent van life home equipment that draw energy:
- Airconditioning or followers
- Electrical heaters
- Induction range
- Fridge
- Oven or microwave
- Hairdryers
- Digital units that require charging like laptops, telephones, cameras, and so on.
Monitor how usually you utilize these home equipment and watch your battery meter to get an concept of how a lot battery energy they use. From there, you’ll be capable to rapidly be taught which units are drawing probably the most energy and if there are extra environment friendly switches you may make (as mentioned later on this article).
2. Put money into environment friendly van home equipment
Some home equipment are particularly designed to be power environment friendly and eat much less energy than others. Though energy-efficient home equipment could price extra upfront, they’re value it for the quantity of energy it can save you.
As you browse for home equipment, you may inform if an equipment is energy-efficient if it has the Power Star label, which implies it meets or exceeds U.S. Environmental Safety Company (EPA) power effectivity requirements.
Most home equipment within the U.S. include an Power Information label on them to clarify how a lot power the merchandise consumes in kilowatt-hours (kWh). You may examine home equipment you’re contemplating to see which makes use of the least kWh.
I additionally suggest searching for home equipment which can be outfitted with energy-saving options. For instance, you can look right into a heater or air-con unit with programmable settings to show off after a sure length of time or as soon as a particular set temperature is reached.
In my van, which was transformed by Outdoors Van, we’ve the Webasto Air High EVO 40 Heater, and I like how we will digitally set our desired temperature. As soon as that temperature is reached, the system idles, which helps us save energy.
If there’s one energy-efficient equipment I like to recommend investing in, it’s the fridge to your van. Take a look at the tip under for the way to decide on an energy-efficient fridge.
3. Select your fridge rigorously
If you consider it, your fridge is the one equipment that’s at all times operating 24/7 in your van. You may as nicely get one which’s not going to fully drain your battery.
Though it might be tempting to choose the most important fridge attainable to your van, smaller fridges are likely to eat much less power than bigger ones since there’s much less to maintain cool. You additionally wish to search for a fridge that has high quality insulation and tight door seals so chilly air doesn’t escape as simply.
The compressor of your fridge is essential because it cools the inside. A fridge with a variable-speed or inverter-driven compressor adjusts its velocity in keeping with the cooling wants versus always operating on the similar velocity.
Most energy-efficient fridges solely draw 1-2 amp hours per hour. I’ve the Isotherm Cruise Class fridge which is tremendous common amongst van lifers. It’s 4.6 cubic toes and has a Danfoss compressor with a low energy draw.
I needed to get a second fridge in my van final 12 months to retailer frozen breastmilk. I used the Nationwide Luna, which is some of the energy-efficient chest-style fridges for overlanders. I used to be stunned at how little energy it drew. Different common fridge manufacturers for van life embrace Dometic, Norcold, and Nova Kool.
4. Park within the solar to maximise photo voltaic charging
Initially, I extremely suggest investing in photo voltaic panels for the roof of your van in case you haven’t already. My first Sprinter van didn’t have sufficient photo voltaic, and I rapidly realized that my battery scenario would have been lots much less disturbing if I had invested in higher-wattage panels.
With photo voltaic panels, you should utilize the daylight to your benefit and cost your batteries throughout the day. Though it’s tempting to park within the shade on a scorching day, I like to recommend discovering a spot within the solar so your panels get the utmost quantity of daylight.
Another choice is to put money into moveable photo voltaic panels which you can prop up within the solar whereas your van is parked within the shade. Then you definitely’ll get one of the best of each worlds!
Important Tip
Clear your Photo voltaic Panels
Your photo voltaic panels will get dusty once you’re driving on filth roads, and all that mud will cut back the ability produced by your photo voltaic panels. Be sure you climb up there periodically to wipe them off with a moist rag. Don’t use any chemical cleaners with out checking together with your photo voltaic producer first!
5. Use window coverings to insulate your van
Though it’s possible you’ll not understand it, your van’s insulation not directly impacts how a lot battery energy you utilize to both heat your van up or cool it down. Correct insulation can regulate the temperature of your van to maintain issues feeling comfy inside. In my van, Outdoors Van used 3M Thinsulate – some of the common and efficient supplies for insulation. Wool is one other insulating materials chosen by van builders.
When you’ve got poor insulation, you’ll seemingly must run the warmth or cooling home equipment like air-con, followers, or a heater extra usually. This may drain your battery energy.
Along with the insulation behind your partitions, window shades, covers, and curtains can all assist insulate your van. In my residing space, I exploit insulating window shades manufactured from closed-cell foam to assist forestall warmth from coming into in the summertime and preserve heat air from escaping within the winter.
I even have window coverings to place over the entrance, driver, and passenger home windows. These are handy for blocking out the warmth from the morning solar. I additionally at all times put these up if I’m stepping out for some time to go on a hike or stroll my canine. These assist regulate the temperature and preserve warmth from the cab from coming into the again of the van.
Outdoors Van made my window coverings customized, however there are different corporations that make window shades for varied kinds of vans.
6. Save the AC for the most popular days
When you’ve got a rooftop AC in your van, you’re seemingly tempted to activate the air conditioner in your van on scorching days. I do know I’d be if I had AC!
Nevertheless, rooftop ACs are one of many quickest methods to empty your batteries, so it’s possible you’ll wish to think about if there are different methods you may enhance the airflow. In any other case, it’s possible you’ll be taking a visit to the RV park so you may plug in!
Earlier than you crank the AC, open your home windows and activate the fan to get some good cross-flow. This can be sufficient to scale back the temperature in your van so that you don’t really feel the necessity to use your AC.
In my van, I’ve two Maxxair followers in my Sprinter van: one above the galley and one above the mattress. I normally have one of many followers programmed to drag contemporary air into the van, whereas the opposite van pushes the stale air out. That together with some vented home windows provides a pleasing breeze once we are sleeping at night time.
After all, in case you plan to spend the summer time in Florida or Arizona, a few followers and a few cracked home windows is not going to be enough. So that you’ll wish to be sure you have ample battery capability as described on the finish of this text.
7. Cost your electronics in public areas
Though I normally work from my van, it’s generally enjoyable to take a look at a espresso store in a mountain city or work in a public library for a change of surroundings. If I do know I’m going to be spending time in a public house with electrical retailers, I at all times carry my units and cords to cost my electronics.
You would carry your laptop computer, cellphone, digital camera, and some other electronics which you can simply transport. You may plug every part in and let it cost again as much as 100% when you get some work achieved earlier than heading again to the van.
8. Keep away from Charging Units In a single day
I like to recommend not overcharging your home equipment by leaving them plugged in in a single day. I’m responsible of plugging in my iPhone earlier than I am going to mattress and letting it cost all night time, even as soon as it has gotten again as much as 100%.
When you’ve got an enormous battery financial institution, this received’t be an enormous deal, however in case you’re actually making an attempt to preserve battery energy in your camper van or are operating low on energy, each little bit it can save you is vital.
Holding electronics plugged in in a single day wastes pointless energy. As quickly as your machine is absolutely charged, it’s best to unplug each the machine and the twine from the outlet to avoid wasting probably the most battery attainable.
9. Unplug units when not in use
Even when your electronics are powered off, they nonetheless eat energy in the event that they’re plugged in. Each time you step away out of your van or go to mattress, it’s best to unplug your whole units and chargers so that they don’t unnecessarily drain your battery.
That is very true of power-hogs like Starlink. Don’t go to sleep watching Netflix and overlook to unplug your Starlink earlier than mattress!
One other trick is to make use of an influence strip for your whole electronics. An influence strip lets you plug in a number of home equipment without delay and switch all of them on or off with a change, making it a handy solution to flip every part off suddenly.
10. Flip off your inverter when not in use
The inverter in your camper van powers your home equipment. It attracts energy when it’s turned on, even when nothing is plugged in and it’s not getting used.
Though the inverter itself solely attracts somewhat energy, forgetting to show it off in a single day might lead to you waking as much as a noticeable lack of battery energy. I forgot to kill my inverter earlier than going to mattress as soon as and seen my battery dropped about 5-10%.
Always operating your inverter additionally provides to its put on and tear. By turning it off once you’re not utilizing it, you may doubtlessly improve the lifespan of your inverter and restrict the danger of needing to restore or change it ahead of needed.
11. Cost issues throughout the day and when you’re driving
In case you’re utilizing photo voltaic panels, it’s best to cost your units when the panels produce probably the most energy, which is often throughout the day when the solar is instantly overhead round midday.
By charging your laptops and telephones throughout the peak daylight hours, you may forestall your batteries from draining in a single day when there is no such thing as a photo voltaic out there.
In case your van battery additionally prices off of your alternator, you too can prioritize charging for once you’re on the street. As soon as your battery hits 100% when you’re driving, you may cost the units with out utilizing any further energy and nonetheless be at 100% battery life once you attain your campsite.
I’ve discovered that with my secondary alternator in my Sprinter van, I can add a ~10% cost for each 20 minutes of driving that I do. Which means that with somewhat over 3 hours of driving, I can fully recharge my battery again to 100%.
12. Maximize pure gentle
The overhead lights in your van may draw extra energy than you assume. As an alternative of reaching for the sunshine change, attempt to use as a lot pure gentle from the solar as attainable throughout the day.
It’s also possible to put money into moveable photo voltaic lights that cost throughout the day that you should utilize in your van at nighttime. When Bearfoot Concept contributor Kaylin’s gentle change broke throughout her 2-month journey to the desert, she used these photo voltaic lights to see inside her van at night time.
13. Develop power-savvy habits
In contrast to a house the place you may unintentionally depart a light-weight turned on all day, it’s best to by no means do that in your van. In case you’re leaving the van, flip off the lights and unplug every part earlier than you go.
With a purpose to preserve your camper van’s batteries, you can additionally tackle some new power-free hobbies. Almost definitely a significant motive you’re doing van life is to attach with nature, so as an alternative of spending hours in your digital units, you may deal with getting outdoors and doing the actions you’re keen on.
There are additionally choices for leisure in your van that don’t require energy resembling books, playing cards, cooking, tenting video games, crafts, and so on.
14. Change gadgets that draw energy when possible
A last tip for conserving battery energy in your van is to search for various units that don’t require energy. Listed below are some concepts for easy switches you may make:
Put money into a Excessive-Capability Battery Financial institution
You may have the entire photo voltaic on this planet, however in case you don’t have wherever to retailer it, parking within the solar received’t do you any good. Photo voltaic can also’t energy your stuff at night time or on cloudy days.
That’s why the scale of your battery financial institution is the largest figuring out consider how lengthy you may preserve battery energy in your camper van and keep off-grid longer.
In case you can afford a high-capacity battery, you may retailer extra of your energy for once you want it. I like to recommend upgrading from AGM batteries to lithium batteries (which is what I did for my present Sprinter van conversion).
Though lithium batteries are dearer, I really imagine they’re definitely worth the funding, particularly in case you stay and work in your van full-time.
With AGM batteries, you may solely use about half of the battery earlier than you could cost them; nonetheless, with lithium batteries, you should utilize 90%. This implies you get much more usable energy out of lithium batteries. Learn this text to realize a greater understanding how your photo voltaic and batteries work collectively and the right way to plan your energy system in your van.
