Off-grid cabins need strong and reliable solar generators for powering appliances and devices. However, cabins vary in size. For this reason, it is crucial to choose a solar generator that will power all of your essentials.
To help guide you, I have made a list of five solar generator options that can be seen below.
I compared the specs and features of all of the following solar generators and ranked them in terms of usability in an off-grid cabin.
Obviously, no one cabin is the same in terms of power consumption, but the following will give you a good estimate of the best one for you and your needs.
|Output:||3,000W Continuous, 6,000W Surge||1,500W Continuous, 3,000W Surge||2,000W Continuous, 3,500W Surge||1,800W Continuous, 3,300W Surge||1,000W Continuous, 2,000W Surge|
|Battery Lifecycles:||2,000 cycles to 80% capacity||2,000 cycles to unlisted capacity||500 cycles to 80% capacity||800 cycles to 60% capacity||500 cycles to 80% capacity|
|Weight:||68 lbs (w/ one battery)||30 lbs (w/ one battery)||70 lbs||31 lbs||22 lbs|
|Dimensions:||18.5 x 12 x 12 in (w/ one battery)||14 x 8 x 9.4 in (w/ one battery)||15.25 x 10.23 x 13.6 in||15.7 x 8.3 x 10.6 in||13.1 x 9.2 x 11.1 in|
The best solar generator for an off-grid cabin is the Titan by Point Zero Energy. It’s power output, solar input, and expandable battery feature gives it the ability to run multiple appliances off-grid for days, weeks, and even months with the proper solar panel setup.
The other options in this “Top 5” review may benefit you better than the Titan depending on what you’re looking to power as well as other features. The table below highlights each model’s best quality.
|Best Overall||Point Zero Energy Titan||Highest power output (up to 3,000W continuous, 6,000W surge) and solar input (up to 2,000W)*||Check price on shopsolarkits.com|
|Best in Versatility||Inergy Flex||30 lbs with one battery; can add up to 96 batteries||Check price on shopsolarkits.com|
|Best Battery Size||Goal Zero Yeti 3000X||3,032Wh battery||Check price on amazon.com|
|Best Power-To-Weight||EcoFlow Delta 1300||1,800W (3,300W surge); weighs 31 lbs||Check price on shopsolarkits.com|
|Best in Portability||Jackery Explorer 1000||Weighs 22 lbs||Check price on amazon.com|
|*Two batteries required for this input/output power. With one battery, these numbers are halved.|
In order to rank these solar generators according to suitability in an off-grid cabin, I created a scenario where I gathered the essential appliances and electronics together in a table to get realistic numbers for power consumption.
Check out the table below for this example scenario along with the total power consumption in a day’s time.
|Appliance/Device||Example Used||Rated Power (W)||Avg. Daily Use (Wh)||Hours of Daily Use||Usage Explanation|
|Fridge/Freezer (10.5-11.5 cu. ft.)||Blomberg 11.43 cu. ft. Bottom Freezer Refrigerator||300W||800Wh||24||Fridge’s maximum rated power is 300W (won’t always run at this rate)|
|Countertop Dishwasher||Farberware Complete Dishwasher||750W||300Wh*||2||Dishwasher will not run at 750W continuously, hence the 300Wh total usage|
|Device Charging (smartphones, laptop, etc.)||(4) standard iPhones @ 5W each (20W);|
(1) 13″ MacBook Pro (60W)
|80W||140Wh||4||About four hours of total phone charging; laptop charges to full in one hour|
|Fan||Lasko 20″ Box Fan||60W||300Wh||5||N/A|
|Lights||(6) 15W LED lightbulbs||90W||400Wh||5||Lights will be used sporadically; five hours total is an estimate|
From the totals in the above table, I have recommended usage instructions for each model after reviewing each one’s specifications/capabilities.
|Titan||Can be used to power all of the equipment listed above every day with one battery pack.|
|Flex||Can be used for all of the above equipment, but you will need two battery packs to successfully run the equipment every day.|
|Yeti 3000X||Can be used to power all of the above equipment every day.|
|Delta 1300||From the examples listed, I recommend using it either only for the fridge or for charging the devices, fan, and lights simultaneously.|
|Explorer 1000||From the examples listed above, it’s best to use it for the devices, fan, and lights simultaneously. Do not use it for a fridge because its solar input is not high enough to recharge its battery for daily use.|
As you can see, the top three solar generators can power all of the appliances and electronics from my example off-grid cabin scenario.
Now, I’ll show you the in-depth features and specifications for each model so you can get more of an idea of what’s best for your cabin’s needs.
1. Titan – Point Zero Energy
The battery capacity of the Point Zero Energy Titan makes it very suitable for cabins. It comes with a 2,000Wh lithium NMC battery. If you need more battery power for your cabin, you can attach multiple batteries together. This gives your generator a longer running time before needing to recharge it.
To add additional batteries to the Titan, you simply attach it to the bottom of the system.
Impressively, the Titan has two charge controllers within it. This gives you increased charging power via solar panels. Moreover, the charge controllers also prevent it from overcharging due to the current flow into and out of the batteries.
- High power output: 3,000W continuous, 6,000W surge*
- High solar input: Up to 2,000W*
- Expandable batteries: This gives you the ability to add multiple batteries to the Titan with ease
*With two batteries attached

2. Flex – Inergy
The Inergy Flex solar generator comes in two models, the Flex AC and Flex DC. The Flex AC is pictured above. In the DC model, the AC ports are removed and replaced with additional USB ports, cigarette lighter ports, among others.
Both models are lightweight and portable for the features that they provide. The Flex AC’s weight with one of its 1,069Wh batteries is 30 lbs, which is relatively light compared to other similar solar generators.
The AC version’s inverter is rated at 1,500W continuous with 3,000W of surge power. As seen from the table earlier in the post, the Flex can be used in cabins to power multiple appliances and devices.
The standard package from Inergy gets you a Flex Power Console and Flex Battery along with a couple of additional items. However, for the off-grid cabin scenario, I recommend getting at least one additional battery.
This will ensure that you will be able to run your appliances for an extended duration and give you a buffer of battery capacity to work with in case you need it.
You can connect as many as 96 Flex batteries for additional power needs. The power station also has an optional MPPT supercharger (affiliate link) that gives it a significantly higher solar input capability.
This ultimately allows it to charge three times faster than the standard model.
