What we like about Goal Zero Yeti 6000X
The Yeti 6000X from Goal Zero is in truth one of the best solar generators we found. You’ll need several solar panels to charge it, but it can be the foundation of your power system in an off-grid environment.
We really liked the addition of wheels to this design, necessary given its weight, but Goal Zero has kept their signature visual footprint in this design, and incorporated some great usability features with the wheels and handle.
What we don’t like about Goal Zero Yeti 6000X
Simply; the price. Though this crazy big capacity from a reliable, excellently built, and stylish product from a reputable company is sure to suit all of your power needs and then some.
This comes at a price, if you can afford it the Yeti 6000X hands down wins, but its price puts it well out of most people’s budgets.
Balancing up your power needs against what you can afford is a really important part of this process. So read on for more information and help when it comes to choosing the best solar generator for you.
- The Yeti 6000X from Goal Zero boasts a capacity that can simply support off-grid living, full time, in a permanent structure, it’s all you need as a system for running everything for days on end.
- Goal Zero is a reputable and dependable company.
- Supportive of massive surges so it can handle any device.
- A system as good as this comes at a price, and this product comes in at more than twice the value of any other on the list, but for a lot more than twice the capacity.
- As you’d expect, a mammoth capacity requires a mammoth amount of time to charge. With an input of 400W from solar, you can expect to fully charge the Yeti 6000X between 18 and 36 hours. So if this was your main system in a permanent off-grid setup, you should consider a secondary smaller and cheaper unit to keep the essentials like a fridge going during your charge times.
After all our research, we’ve decided to hand first place to both the Bluetti EB240, and the Jackery Solar Generator 1500. Both are such fantastic options for off-grid living, coming equipped with their own solar panels and priced in similar regions.
The Bluetti EB240 is the perfect all-rounder with its extra-large capacity and many ports available to all your devices for living off-grid, even in a permanent setup when solar power needs to be relied upon heavily.
Unfortunately, it’s lacking in being able to handle those high-power devices.
It’s been designed for low usage for a long time, and as such its low surge rating means it might not be adequate for permanent off-grid living situations, though it is perfect for semi-permanent off-grid living survival situations, emergency preparedness, over-landing, or those extended camping trips.
Where the Bluetti EB240 falls down, the Jackery Solar Generator 1500 picks up the torch.
Its higher continuous power and surge ratings make it the most widely applicable product for all your power needs.
Though unfortunately, it does just have that smaller capacity. But considering its fast charging capabilities and its coming with 4 solar panels, it deserves its place at the top of our list.
It’s really about your power needs and the situations you’ll be in when it comes to selecting your solar generator for off-grid living.
So we hope our list has narrowed things down for you. Read on for a lot more help when it comes to what you need to consider when selecting what’s right for you.
Which Solar Generator for Off-Grid Living is right for me?
Solar generators are an excellent option for getting power to where you need it in an off-grid living situation. Whether you’re living in a permanent structure in an off-grid location, traveling around in an RV, or Overlanding for extended periods of time in survival situations.
Solar generators harness the sun’s energy and convert it into usable power to power your devices. They consist of Solar panels, and a generator, which is essentially a huge power bank.
This means you can collect and store energy in a clean green and efficient way, without any smelly fuel being burned and polluting the atmosphere, and without all the noise that comes with a conventional fuel generator. And of course, you don’t run the risk of running out of fuel.
But when it comes to choosing the best type of generator for you, the task can become daunting, and the technology intimidating. Keep reading and we’ll go through all you need to know to find the best device for you and your family.
So how do solar generators work?
All solar generators have the following basic components:
- Solar panels for converting the sun’s energy into electricity for your needs.
- A battery to store the power.
- A charge controller to control the flow of charge to the battery.
- And an inverter, which converts the current of the power stored in the battery into usable power for your devices.
When it comes to choosing the best solar generator for you there’s really only one thing you need to determine first. What do you need? Knowing your power requirements, and how you’re going to need to use the power is essential to start looking for the best solar generator for you.
Since the market is full of manufactures and models that overlap so broadly in their costs and benefits, it’s really about finding the one that’s going to do everything you need for your specific circumstances.
For off-grid living situations, there’s a very important factor to consider. Do you need continuous power? And how much of it will you need?
Solar generators can be a great way of providing this power in an off-grid scenario, but they can be slow. If you’re needing to power many devices that need to be on all the time, such as a fridge, water pump, ac unit, etc.
Then building a system to get you that reliable stream of non-stop power is going to be more difficult. Solar generators store their power in batteries, which need to be recharged between uses.
Many solar generators can’t charge and use power at the same time, so you should consider this when deciding what type of system you need.
But as well as determining your power needs, you need to consider what you can afford, and which features are important to you. Looking into these factors will make establishing which devices will work for you and which won’t a lot easier.
What size solar generator is best for me?
There are two critical ratings when it comes to solar generators, continuous Watts and surges Watts. Continuous Watts is the power that can be consistently maintained the entire time the generator is in use. And surge Watts is the maximum wattage your generator can withstand for an initial start-up of electric motors.
To calculate continuous power, we multiply the number of Watts being used, by the number of hours they’re being used for.
So for your needs, add up the total Watts all your devices will need (a phone charger is around 10 Watts, a laptop charge around 100 Watts, and a fridge upwards of 500 Watts daily) and multiply that by the number of hours you’ll need to run everything daily.
So if you were living off-grid in a van or RV, running a fridge all day, and let’s say 1 laptop charge and 2 phone charges daily, a 700w solar generator would probably be enough for your needs.
If you’re living in a more long-term outfit and running lighting, kitchen appliances, a fridge freezer, maybe even a water pump, your energy requirements are going to be much higher and they’ll be a limit where a solar generator can’t quite provide all you need.
If that’s the case you could look at using multiple batteries and multiple solar panels, so the panels can always be charging batteries whilst others are being used.
In that case, a solar generator can be that fantastic bit of kit to give you that much extra for peace of mind and dependability in a blackout or survival situation.
When it comes to surge, Watts, this is the initial burst of power devices with electric motors need, some solar generators are capable of withstanding 3500w surges, making them more than enough for even the beefiest power tools if you’re working off-grid.
So if you have a fridge that uses 500 Watts daily, but needs 1500 Watts to get it going in that initial second surge, you’re going to need a solar generator with a 1500 watt surge rating.
Other things you need to consider when choosing a solar generator
The energy production of Solar panels is also something we measure in Watts. The watt rating of the panel multiplied by the number of hours sun exposure gives you the number of Watts produced and stored in your generator.
So if you’re using a 100-watt solar panel for 5 hours, you’re going to produce 500 Watts of usable energy. So let’s go back to our scenario requiring a 700-watt solar generator. We’re powering a fridge daily, 1 laptop charge, and 2 phone charges daily for an off-grid, van life type arrangement.
A single 100W solar panel on your roof is going to take 7 hours to charge the generator, many generators can’t be used during that time.
2 200 watt solar panels on the roof are going to give you 400 Watts an hour, meaning you’ll charge your 700W generator in as little as 1 hour 45 minutes. But of course, 2 200 watt panels are going to cost you more than 1 100 watt panel, so it’s about balancing things up for your needs.
Also, consider with solar panels, day sun exposure will constantly vary, and cloudy days will mean your panels are less efficient and take longer to charge your generator.
Your generator can only use stored energy, so if your panels can produce more energy than your battery can store, it will be wasted energy and you won’t gain any extra power.
There’s no point trying to charge a generator that can only take in 100 Watts an hour with 4 100 watt panels, you’ll still only get 100 Watts an hour, and the other 3 panels’ power won’t be going into the battery.
Battery power and Capacity
The capacity of your solar generator is the maximum power your battery can store. But this doesn’t always mean that power is available all at once.
That comes down to the battery’s power rating. So if the capacity of your bank is 1500 watts but the power rating is only 500 Watts, then the most power a device can use continuously is 500 Watts.
It’s important to check these factors picking which solar generator is best for you
Some solar generators use trickle charging, this means you can use the battery whilst charging it, meaning you can rely on your continuous power a lot more and will need an overall smaller unit. But this technology is expensive and only comes with the best solar generators.
A range of battery types exist, but the most commonly used are lithium-ion and lead-acid.
Lithium-ion batteries are lightweight, compact, and generally last a long time, they’re the type typically used for power tools. They have a longer lifespan than lead-acid batteries and these factors make them popular for solar generators.
Lead-acid batteries are the most common and least expensive. They’re the types used in cars, but their short life spans mean solar generators that use them won’t last as long and you’ll have to regularly replace your system.
Power inverters convert DC (direct current) energy to AC (alternating current) DC is the type of power stored in a solar generator’s battery, but AC is what most appliances use, and is what comes out of your wall outlets.
Pure sine wave inverters will protect your devices and provide more consistent and reliable power, but any soar generator that uses a pure sine wave inverter will be more expensive.
Solar generators need charge controllers to regulate the current for the solar panels and stop the batteries from overcharging. The most basic ones just cut the power when full charge is reached, but this can be inefficient.
Generators with MPPT charge controllers will be much more efficient and squeeze more power out of your rig. MPPT stands for maximum power point tracking, and it just means they can handle the current more effectively.
For the best usability in your device, look for a solar generator with a digital display. Some of these can be very basic, and others much more detailed, showing the AC and DC power being used and how much charge is left in the battery.
Weight is an important factor to think about depending on your circumstances. If you’re living permanently off-grid in an established setup, weight is less important as your system can remain relatively unchanged once you set it up.
If however you’re living in a van or RV, doing camping or survival trips and your solar generator is going to move around a lot more, weight suddenly becomes very important.
The weight of Solar generators can vary anywhere from 5 to 30kg, and that’s a lot if you were needing to carry your generator from your van, truck, RV, etc, to a survival camp you’ve set up in the bush. Something to think about depending on what you’re going to be doing.
Things to avoid
Like with all purchases, there are certain things to be aware of when making any decisions on which solar generator is right for you.
Having weighed up your own needs in terms of how much power you need, what appliances you’ll be using it for and how long you’ll need power, as well as taking into account recharge times and your budget, the rest of your decision should factor in how your purchase will fair long term.
Longevity on items as costly as solar generators is extremely important, and there’s little point going for cheaper options based purely on their price, only to find you have to replace them in a relatively short space of time.
So what to look out for? As solar generators hit the market and began to grow in popularity, they used proprietary components that could often not be upgraded or replaced, meaning entire units needed to be replaced directly from the manufacturers at hefty prices.
It’s important any piece of emergency equipment is realistically usable and repairable in the real world with off-the-shelf components.
Also, look out for kits that are sold as only one part of a system, and require costly additions. Buying a generator alone could be a good option for you if you already have standard panels, but these can often be costly options.
Watch out for systems with proprietary options that no longer make replacement parts.
Waterproofing is an important factor for a device intended to be used as survival equipment and emergency preparedness in an off-grid environment. But through lots of options that come with waterproofing it’s not standard in the industry yet, so weigh that up in your decision.
A warranty is always a huge weight off your mind when it comes to purchasing decisions, so look for solar generators that come with warranties, and watch out for companies with little or no industry presence.
Many cheaper options are vastly available, but if you’re buying from a company no one ever heard of, you should set low expectations for things like built quality, reliability, and durability, and next to no expectations in terms of customer service and support.
The leading industry experts hold their positions for a reason, so trust them. Buy once, cry once.
A Final Summary
So as we’ve learned, solar generators are a fantastic piece of kit to have on hand when setting up an off-grid living situation in a permanent structure, or for prolonged trips doing off-grid traveling in RV’s, 4×4’s or vans, they can save your life in a survival situation and bring all the creature comforts of home to an Overlanding or camping trip.
Generally, they’re solid pieces of kit that you can rely on to last a long time, but all good things come at a price.
What’s most important is you understand your own needs for how much power you’ll need and for how long, in order to make sure you’re making the right decision when it comes to which solar generator can improve you and your family’s lives.
