Powering Your Camper: Off-Grid Solutions For Camping Trips

If you're looking to power your camper without a plugin, there are a few options available to you. One option is to use a portable power station, which can be easily recharged by driving, using a solar panel, or plugging into a wall outlet. Another option is to install solar panels on your camper, which can provide a steady supply of power. Additionally, you can use a generator to create power, either through a portable generator or an onboard generator for larger motorhomes. If you're looking for free electrical hookups, some publicly managed RV parks, casinos, fairgrounds, and sporting arenas may offer complimentary electricity. However, it's important to note that these options may not always be reliable and you may need to do some research ahead of time.

Charging with the vehicle's battery

Using a 12V Inverter

Plug a 12V inverter into the cigarette lighter of your vehicle and charge your devices while it is running. Inverters such as the Bestek 500 W Power Inverter have several ports to charge both 110V AC devices (like a laptop) and USB-powered devices (like a phone).

Using an Inverter Connected to the Vehicle Battery

Connect an inverter directly to your vehicle battery with cables. This method is useful when you need a lot of power in a pinch. However, you will usually need to keep your engine running so your battery doesn't die. An example of an inverter that can be used for this purpose is the Yinleader Car Power Inverter 1000W/2000W(Peak).

Using a Continuous-Duty Solenoid

Install a continuous-duty solenoid in your vehicle to draw the extra power your alternator creates when you drive to charge a house battery. A solenoid will automatically charge your house batteries while you drive. You can install one yourself if you're handy, or get an RV or mechanic to help you out.

Charging with a generator

Charging an RV battery with a generator is a straightforward process, but it's important to take safety precautions and understand the limitations of this method. Here are the steps you need to follow:

Step 1: Safety Precautions

Before you begin, ensure that you're following all safety precautions for handling a 12-volt battery and portable generator. Make sure both units are in safe, working order and inspect them for any damage. When charging your battery, do so in a well-ventilated area, and wear goggles and gloves to prevent injuries. It's also best to charge your battery when the temperature is moderate to ensure optimal power retention. Always refer to the manufacturer's instructions to ensure a safe charging process.

Step 2: Prepare the Generator

Before starting your generator, check the oil, fuel levels, and air filter. If you're using a Honda generator, turn the eco-throttle switch off, turn the fuel valve on, pull the choke to the closed position, and turn the key to the "On" position. Finally, push the choke knob back in. Allow the generator to warm up for a few minutes before connecting any power cords or appliances.

Step 3: Connect the RV Power Cord

Plug the RV power cord into the generator's built-in 30 amp/120-volt AC plug, just as you would at a campsite power post. If your RV's power cord doesn't fit, you may need a 30-amp twist-to-30-amp RV adapter.

Step 4: Monitor the Charging Process

Once everything is connected, your generator will start recharging your RV batteries and powering any electrical appliances in your vehicle. The time it takes to fully charge your RV battery depends on various factors, including battery capacity, generator output, the number of appliances in use, and the number of batteries being charged. Typically, if your RV battery is depleted to 20-30% power, it can take up to 8-10 hours to fully charge. If your battery is almost full, it might only take a few hours to reach full capacity.

Step 5: Troubleshooting

If your generator doesn't charge your RV battery, there are a few things to check. Ensure that the battery disconnect is not disconnected, the converter circuit breaker is on, fuses are intact, and the main breakers on the generator are not tripped. Additionally, check the water level and overall condition of the battery. If you're unsure about troubleshooting, consult a certified RV professional.

Charging with solar panels

Solar panels are a great way to power your camper without having to plug in. The sun is a free and abundant source of energy that can be harnessed to power your RV and charge your electrical devices. There are a few different options for charging with solar panels, each with its own advantages and disadvantages.

Portable Solar Panel Kits

Portable solar panel kits are typically sized between 50 and 200 watts and can meet basic electrical needs. These kits are all-in-one solutions that do not require any special installation or knowledge. They are easy to set up and can be used to charge your RV batteries and power devices such as lights, fans, propane appliance electronics, and phone chargers. However, they may not be powerful enough to run larger appliances such as TVs or computers.

RV Solar Battery Tenders

RV solar battery tenders are designed to keep your batteries charged and healthy even when you're away from your RV. These systems do not provide enough power to run appliances but can help to prevent your battery from draining when not in use. This is especially useful if your RV is stored outside and you want to prevent the battery from dying.

Large RV Solar Systems

Large RV solar systems are more complex and typically include solar panels, charge controllers, batteries, and inverters installed in the RV. These systems can serve as primary power sources and can even run high-power appliances such as air conditioners or electric cars. However, they require a good understanding of electricity and should not be attempted by novices.

Mounted Panels vs Solar Suitcase

If you only need a small amount of solar power (around 100 watts), a solar suitcase might be a good option. This allows you to position the panel towards the sun as it moves across the sky, providing the most effective charge. However, it needs to be stored, packed, and unpacked periodically. Mounted panels, on the other hand, are a better option if you want a heftier solar setup. Multiple panels can be mounted on the roof of your RV, providing a significant amount of power. However, they need to be properly installed and can make your RV warmer in the summer months.

Tips for Maximizing Your Power

• Always be charging: Take advantage of driving time to power your battery and electronic items by using a solenoid to power your house battery and plugging everything into a power station that's charging.
• Use rechargeable electronics: Many electronic items are now available in USB form, which can help conserve power.
• Use solar lights indoors: Instead of drawing power from your house batteries, use solar lights that you can charge during the day and save power for other appliances at night.

Charging with wind power

If you're looking to harness the wind to power your camper, you're in luck! Wind power is a viable option for generating electricity when you're off the grid. You can use portable wind turbines, also known as windchargers, to generate wind power for caravans, campers, and motorhomes. These turbines are typically mounted on the vehicle's roof, ladder, or a freestanding pole, and they work by capturing the wind's kinetic energy to turn a generator and create power.

The amount of power generated by a wind turbine depends on the wind speed and the size of the turbine. At lower wind speeds, you'll only produce a fraction of the turbine's capacity. For example, a 10-knot (11 mph) wind may only generate about 40 watts of power, which is a small fraction of the power needed to run appliances like a microwave, coffee maker, or toaster. To generate their maximum output, most wind turbines need wind speeds of 20+ mph.

Combining with Other Power Sources

To ensure a steady power supply, it's a good idea to combine wind power with other sources, such as solar panels or a generator. Many campers use wind turbines as a supplement to solar power, as even on cloudy days, solar panels can still produce some energy. Additionally, in strong winds, you may not want to be camping, so having a backup power source is a good idea.

Things to Consider

There are a few drawbacks to using wind power for your camper. Firstly, setting up and taking down the turbine each time you move camp can be inconvenient, especially if you travel frequently. Secondly, wind turbines require unobstructed wind to work effectively, so you'll need to camp in an open area without large items, trees, or hills blocking the wind. Lightning strikes are also a concern, as raising the turbine high up increases the risk of a strike, which can damage or destroy the equipment.

Products to Consider

If you're interested in using wind power for your camper, there are a few products on the market that might suit your needs. The Rutland Windcharger systems are designed for caravans, campers, and motorhomes, and they can provide complete energy independence. Another option is the Rutland FM910-4 Furlmatic, a well-tested turbine suitable for static caravans or off-grid homes.
