Output and Power Needs
When you buy a generator for off-grid living, you need to make sure that it has enough power to keep your appliances running without any fluctuations. The best way to do this is to make a list of all the appliances in your cabin or RV and then mention their starting and running wattages. Calculate the total of both to find your power requirements. To help you sort this out, we have given an example below.
|Appliances||Starting Wattage||Running Wattage|
|10000 BTU Air Conditioner||2000||700|
|Laptop and Phone Charger||500||500|
In the example above, 7170 watts are needed to start all the appliances at one time, and 5470 watts are needed to keep them running simultaneously. In this situation, a generator of 6000 watts will be ideal. You don’t need a generator according to the starting wattage but as per the running power needs. You can add the appliances one by one so that they release the extra load. If your needs are less, you can edit the table above and find out the power requirements. Remember, load management is an important aspect of getting more out of your generator.
Inverter vs. Conventional Generator
The next big thing to consider is going for an inverter generator or a conventional generator. If your main concern is to power sensitive appliances like laptop/phone chargers, medical equipment like CPAP machines, then an inverter is best for you. However, if you need more power to run appliances like air conditioners, well pumps, heat pumps, and other heavy appliances, a conventional generator is the best. Inverters provide you with clean power but have a limited output. They are also less noisy and lightweight compared to classical generators and are also expensive. On the other hand, conventional generators are capable of producing more power as compared to inverters, and cheaper than inverters. The inverter vs. generator debate boils down to two things; type of power and amount of power you need.
Type of Fuel
If you are going for an inverter generator for your off-grid adventures, you will be limited to gasoline/propane generators. On the other hand, with a conventional generator, you will have the option of going for single fuel or dual fuel generator. You can choose a gas, propane, or diesel generator for off the grid cabins. If you plan to go off-grid on your RV, it is best to choose the fuel type according to your RV engine. If you have a diesel RV, buying a diesel generator is a great option. However, it is best to have a dual fuel (gas and propane) generator when it comes to off-grid living. The reason is that it is possible that you may not find gasoline easily in remote areas. Gas has a short shelf life (8-10 months) compared to propane (8-10 years). You can easily store propane cylinders in your cabin without any worries. Gas is also highly flammable as compared to propane and can be more hazardous. Please keep in mind that gasoline has a higher energy rating than propane but propane burns cleaner. Diesel, on the other side, has a higher energy rating than gasoline and propane. Its burning is not clean but provides a better runtime.
Gas Tank Size and Runtime
If your power needs are high and you want your generator to run continuously for 6-9 hours, then go for a generator with a large tank size. As the tank size increases, run time also increases. To increase the run time, it is best to keep the load at half of the generator’s total output. Some generators come with efficient engines that conserve fuel and provide you with a better run time.
Look for a generator that offers maximum options on the control panel. The latest model will come with various meter readings, low oil and fuel indications, and an odometer to display the total running hours of the generator.
If you plan to run your generator with an RV, make sure it has all the power outlets to directly connect your appliances. If you are connecting your off-grid cabin with your generator, it must be transfer switch ready. We suggest that you don’t connect the generator directly to your cabin without a transfer switch. It can back feed and cause problems to the appliances and the generator.
When you are off the grid, you will need to move around your generator frequently. Hence it is best to look for a generator with all the portability features. An off-grid generator must have push/pull handles with an ergonomic design and durable wheels. If you are going for an inverter generator, it must come with a carry handle and wheels.
If you don’t want to go out from the luxury of your cabin, buy a remote start generator. Otherwise, you will have to settle for an electric start or recoil starting the generator. Electric start generators save you from the hassle of pulling the starting ropes, but you still have to go out. Remote start generators are costly than electric start or recoil start models.
A generator must always be safe to use. It must come with features like surge protection, auto shutdown in response to overheating and overloading, and low oil. Make sure you look for covers on the power outlets to keep them safe from dust and water while your generator is outside.
We don’t want you to disturb the peace of your off-grid living area. Therefore, it is better to look for a generator with a minimum sound rating. Inverters are less noisy compared to conventional generators. Some states limit the noise output from a generator. You must check the local laws before buying a generator. Secondly, a quiet generator will also give you peace of mind.
Warranty and Certification
Look for a generator with a warranty. The warranty covers come in handy when you have to get your generator repaired within 1-2 years of purchasing. Friendly customer service will help you set your generator for the first time and solve your queries later on. If you are a resident of California, don’t buy a generator that is not certified by CARB. Generators certified from EPA also ensure that the air quality is not affected due to generator exhaust.
The last thing, but one of the most important, is the price. If you are buying an advanced machine with all the latest features, you will have to pay more. Inverters and diesel generators are costly compared to single fuel conventional generators.
