Get Up To $650 Off on Worksport’s End of Summer Sale
You want off-grid power, but you do not want a gas generator sitting in your truck bed. That is fair. Generators are loud. They smell. They need fuel you have to haul, store, and pour in the dark. They cannot run inside a garage or tent because of the fumes. And they always seem to sputter out right when you need them most.
There is a cleaner way to keep your tools, fridge, phones, and lights running. You can turn your truck into its own power source. A solar array on the bed makes the electricity. A modular battery system stores it and hands it back through normal wall outlets. No pull cord. No gas can. No noise.
This guide shows how off-grid power without a generator actually works, what a truck based solar setup can run, how to size one to your truck, and how to build it for less during our End of Summer Sale.
⛽ The trouble with gas generators
Gas generators feel simple until you live with one. The fuel adds up. You are stuck buying, hauling, and storing gasoline that goes stale in a few months. The noise is real. Most portable units run at 65 to 75 decibels, about as loud as a vacuum cleaner that never turns off. That is a fast way to annoy every neighbor and campsite around you.
Then there is the safety problem. Gas generators give off carbon monoxide, so you can never run one indoors, in a garage, or in a closed tent. They need oil changes and tune ups. And they only make power while they are running and burning fuel.
For a lot of people, a generator is loud insurance they hope to never use. A solar and battery setup flips that. It works quietly in the background, refuels itself from the sun, and is safe to use right next to you.
☀️ How a solar truck makes its own power
A truck based system has two simple parts that work together.
The first part is the solar array. The Worksport SOLIS is a custom fit, folding solar array that mounts right on your truck bed. It looks and works like a hard bed cover, so it protects your cargo underneath. The difference is that its surface is covered in solar panels. While you drive or park in the sun, it makes clean electricity. The long bed Large size generates up to 480 watts.
The second part is storage. Solar power is only useful if you can hold onto it and use it later, at night or when clouds roll in. That is the job of the Worksport COR, a modular power system built around swappable LiFePO4 batteries. SOLIS sends its solar energy into COR through industry standard MC4 connectors. No special cables and no complicated setup. You plug in and start filling the battery.
Once the energy is stored, COR gives it back as normal household power. It has four 120 volt outlets and puts out 2000 watts of clean, pure sine wave electricity, the same kind that comes out of the wall at home. It also has fast USB-C and USB-A ports, a car style port, and bright built in LED lights.
Together, SOLIS and COR turn your truck into a rolling power plant. The sun fills the batteries. The batteries run your gear. When one battery gets low, you swap in another in seconds, with no tools and no downtime.
🔌 What you can run without a drop of gas
A common worry is that solar cannot run “real” things. It can. Each COR battery holds about 1 kilowatt hour of energy, and you can carry more than one. Here is what a single COR battery can handle.
| What you plug in | Roughly how long it runs |
|---|---|
| Refrigerator | Up to 36 hours |
| CPAP machine (with humidifier) | Up to 15 hours |
| Wi-Fi router | Up to 7 days (about 170 hours) |
| Power tool batteries (20V pro packs) | Up to 8 or 9 recharges |
| 55 inch 4K TV | Up to 8 hours |
| Phone | 60 or more full charges |
| LED work light | Up to 90 hours |
Estimates based on the COR 960 Wh nominal battery, at about 85% efficiency for USB and DC charging and about 80% for AC devices. Real runtime changes with power draw, temperature, and how you use it. Add another battery to double or triple these numbers.
Because COR uses LiFePO4 battery chemistry with Smart HeatSense protection that watches every cell for early heat changes, it is safe to run right next to you, indoors or in a tent. No fumes. No carbon monoxide. Just power.
🚚 Build a setup that fits your truck
The nice thing about going off-grid this way is that you start with what you need and grow later. There is no giant upfront system to buy all at once.
Start by matching a SOLIS size to your truck bed:
• ☀️ SOLIS Small fits mid size and short beds, about 4 to 5 feet. Think Maverick, Tacoma, Ranger, Frontier, or Colorado.
• ⚡ SOLIS Medium fits 5.5 to 6 foot beds, like the F-150, Ram 1500, or Tundra.
• 🔋 SOLIS Large fits full size 6.5 foot long beds, like the Silverado, Sierra, or Ram, and makes the most power at up to 480 watts.
Every SOLIS is 100% assembled in the USA, built to order with an aircraft grade aluminum frame, a weathertight seal that helps keep out rain, snow, and dust, and a low profile that looks factory clean on your truck.
From there, add a COR power system to store and use the energy. Start with the hub and one battery, then add more batteries any time you want longer runtime. Want a cleaner, stronger install? The vehicle specific SOLIS Mount Kit is an easy upgrade for a factory finish look.
That is the whole idea. One system that protects your bed, makes its own power, and gets bigger only when you want it to.
⚖️ Gas generator vs. solar truck power
| Gas generator | SOLIS + COR | |
|---|---|---|
| Fuel | Gasoline you buy and store | Free sunlight |
| Noise | Loud, 65 to 75 dB | Quiet |
| Fumes | Carbon monoxide, outdoor only | None, safe indoors |
| Upkeep | Oil changes and tune ups | Almost none |
| Refuels itself | No | Yes, from the sun |
| Protects your truck bed | No | Yes, doubles as a bed cover |

❓ Frequently asked questions
🔌 Is off-grid power without a generator really enough to run my stuff?
For the things that matter most, yes. A single COR battery can keep a fridge cold for well over a day, run a CPAP overnight, keep your router online for days, and recharge tools and phones many times over. Add batteries for more.
⛽ How is this different from a gas generator?
It makes no fumes and almost no noise, so it is safe to use indoors or in a tent. It refuels itself from the sun instead of from a gas can. And it needs almost no upkeep. There is no oil to change and no fuel to go stale.
📏 What size SOLIS do I need?
Match it to your truck bed. Small fits 4 to 5 foot beds, Medium fits 5.5 to 6 foot beds, and Large fits 6.5 foot long beds. If you are unsure, check the fitment list on the SOLIS product page.
🔋 Can I add more power later?
Yes. COR is modular. Start with one battery and add more whenever you want longer runtime. Each battery adds about another kilowatt hour, and you can swap them in seconds with no tools.
☁️ Does solar still work when it is cloudy or shaded?
It keeps working, just slower. SOLIS panels are parallel wired, so if one section is shaded the rest keep generating. You make less power on a gray day, but you still make power, and the battery holds what you already stored.
🎯 Ready to cut the cord on gas?
Off-grid power without a generator is not a someday idea. It is a setup you can build on your own truck this weekend. Pick the SOLIS size that fits your bed, add a COR power system to store the energy, and never wrestle with a gas can again.
