If you're planning an off-grid camping trip, you might be wondering if you can use a generator with your RV. The good news is that it's entirely possible and safe to hook up a generator to your campervan in many cases. Portable generators can be a great addition to your camping setup, providing a safe power supply when you don't have access to full hookups. They can also be used as a backup power source during power outages at home. However, there are a few important considerations and safety precautions to keep in mind before plugging in your generator.

Choosing the right generator for your camper

Camper Size and Type

The size and type of your camper will play a significant role in determining the right generator. Different campers have different electrical demands, so it's important to assess your specific needs. Consider the size of your camper, the number and type of appliances you'll be using, and any other electronic devices you plan to power.

Power Requirements

Understanding your power requirements is crucial. Make a list of all the appliances, electronics, and devices you intend to use simultaneously and calculate their total power consumption. Consider the wattage, voltage, and amp requirements of each item. This will help you determine the generator's capacity needed to meet your demands.

Generator Type

Generators for campers typically come in two types: portable and built-in/stationary. Portable generators are versatile and can be used for various purposes, including camping and home backup power. Built-in generators, on the other hand, are usually pre-installed in larger RVs and are wired directly into the electrical system. They often use the RV's batteries or propane/natural gas as a fuel source.

Fuel Type

Generators can be powered by different fuel sources, each with its own advantages and disadvantages. Solar-powered generators are becoming increasingly popular due to their eco-friendliness and reduced carbon footprint. However, gas, diesel, and propane generators are more affordable, widely available, and can provide continuous power with sufficient fuel.

Noise Level

If you plan to visit national or state parks, noise restrictions are important to consider. Look for generators with lower decibel ratings, typically below 60 dB, to ensure you comply with campground regulations. Quieter generators are also more considerate of your fellow campers.

Safety

Safety should always be a top priority when using a generator. Ensure that your generator is placed on a level, flame-resistant surface, and maintain a safe distance from your camper and other objects. Follow the safety guidelines provided by the manufacturer, and be mindful of carbon monoxide hazards.

Recharge Options

Consider how you will recharge your generator. Some generators require refuelling, while others can be recharged using solar panels, shore power, or car adaptors. Think about the convenience and availability of your chosen recharge option.

Portability

If you opt for a portable generator, weight and compactness are important factors. Lighter and more compact generators are easier to transport and store, but they may come with lower capacity. Balance your power needs with the portability of the generator.

Cost

Finally, consider your budget. Generators can vary significantly in price, depending on their type, capacity, and features. Shop around and compare prices to find the best option that suits your financial plan.

Remember, choosing the right generator for your camper involves careful consideration of your specific needs, power requirements, and budget. Always prioritize safety and follow the manufacturer's instructions for proper use and maintenance.

Safety precautions when connecting a generator to a camper

Connecting a generator to a camper can be a great way to provide power when camping, but it's important to follow safety precautions to ensure a safe and enjoyable experience. Here are some detailed instructions to ensure safety when connecting a generator to a camper:

Generator maintenance and refueling

Generator maintenance is essential to ensure reliability, efficiency, and longevity. Here are some detailed instructions for maintaining and refueling your generator:

Maintenance

• Regular Inspections: Before each trip, conduct a visual inspection of your generator. Check for loose connections, leaks, and any signs of wear or damage. This helps catch minor issues early on.
• Oil and Filter Changes: Change the oil and oil filter every 100 to 150 hours of operation or at least once a year. Fresh oil maintains engine performance and reduces wear, preventing costly damage. Check the oil level before each trip, ensuring the generator is on a flat surface and has cooled down.
• Air Filter Replacement: Replace the air filter every 300 hours or annually. A clean air filter ensures optimal airflow for combustion. Inspect the air filter every 50 hours of operation for dirt, debris, and damage. Replace or clean the filter as needed.
• Fuel System Maintenance: Use fuel stabilizers to prevent fuel degradation, especially if the generator is unused for long periods. Add a stabilizer to the gas tank and run the generator for a few minutes. Also, periodically clean the fuel system using a fuel system cleaner to prevent deposits and blockages. Inspect and replace fuel filters as needed.
• Spark Plug Maintenance: Spark plugs are crucial for engine ignition. Inspect and replace them every 100 hours of operation or if they show signs of wear or carbon buildup. Ensure proper gap and installation by checking with a spark plug gap tool and tightening to the manufacturer's specifications.
• Battery Maintenance: Check the generator's battery regularly. Inspect the battery terminals for corrosion, and clean them if necessary. Monitor battery voltage and charge or replace the battery as needed.
• Cooling System Maintenance: Check the coolant level regularly, topping it up as needed. Inspect the cooling system for leaks and repair them promptly. Clean the cooling fins with compressed air or a soft brush to ensure efficient heat dissipation.
• Professional Service: Have your generator professionally serviced at least every two years or every 500 hours. This ensures that any issues you might have missed are addressed.

Refueling

When refueling your generator, always ensure it is turned off and allowed to cool down for 5-10 minutes before removing the fuel cap and refilling. Use the correct type of fuel as recommended by the manufacturer. Incompatible fuels can cause engine seizure. For dual-fuel generators, consult the owner's manual for switching between fuel types.

Camper electrical system vs. house electrical system

A camper's electrical system is quite different from a house's electrical system. A house is connected to a constant and virtually limitless source of power, whereas a camper's electrical system is not. A camper's electrical system has three main parts: the power source, the charging source, and the loads.

Power Source

The power source for a camper's electrical system is usually a 12-volt DC system, powered by a 12-volt battery or multiple batteries wired together in a parallel circuit. In contrast, a house's electrical system is typically a 110 or 120-volt AC system.

Charging Source

The charging source for a camper's electrical system can be solar panels, the vehicle's alternator, or by plugging into an outlet. Solar panels are a great way to charge the batteries, and the more panels there are, the faster they will charge. The vehicle's alternator can also be used to charge the batteries, but this requires the engine to be running. Plugging into an outlet requires an AC-to-DC charger, and this method can be used as a reliable charging source when the camper is parked in a driveway or at an RV park.

Loads

The loads in a camper's electrical system are all the things that use electricity, such as lights, fan, heater, fridge, and outlets for charging devices. These loads must be 12V appliances as they are powered directly by the 12V batteries in the camper. To use household appliances that require AC power, an inverter is needed to convert the 12V DC power from the batteries to 120V AC power. However, using high-load appliances can drain the batteries very quickly, and certain appliances such as space heaters and hair dryers should be avoided entirely.

Limitations

Unlike a house's electrical system, a camper's electrical system has limitations. The batteries can be drained quickly, especially when using high-load appliances. Additionally, certain appliances that require a lot of power, such as air conditioning, may not be practical for a camper's electrical system as they would require a large number of batteries and solar panels. Therefore, it is important for camper owners to understand the limitations of their electrical system and monitor the charge state of their batteries to avoid issues.
