After a list of highly portable briefcase solar generators, we would like to introduce you to a list of heavy-duty solar generators here. As you see, a heavy-duty solar generator is not much friendly for portable use. Obviously, you couldn’t easily carry a hefty solar generator on an individual camping or outing trip. Instead, a large solar generator is suitable for use in an RV, trailer, boat or cabin, and etc. Also, you can keep a big solar generator in your home to meet an emergency.
There is a big variety of heavy-duty solar generators out there. There is actually no specific form for what a solar generator to be. We consider any device that could harvest and store the energy from the sun a solar generator. In that sense, all the solar-enabled power stations are solar generators.
By the way, the term solar generator is factually a misnomer as long as you couldn’t produce energy from such a device all-the-time as you could do with a diesel generator. Unlike a diesel alternative, a solar generator makes power only when there is the sun in the sky. Hence, you wouldn’t rely on it as much as you could do with a diesel one.

With its huge size, this is only suitable for tents, camps, RVs, and trailers. Use the link below to check its price and buy a unit if you like it.
Could you imagine such a powerful solar generator? Of course, that is a reality now. No other firm has brought into the market such a gigantic solar-based machine ever.

Yes, you need to pay extra for the panels, but you get the best results out in the wild with the those highly portable Boulder chargers.

And its weight goes at 68.6 lbs and added with the solar chargers it is rather heftier. But that doesn’t matter because the device is mainly for the use in cabins, RVs, trailers, campers, homes, and etc. You can keep this anywhere in your living space and put connected to the solar chargers.

This is another important pick on our list of the heavy-duty solar generators. Well, at an affordable price, you get a cool solar generator for emergency, camping and household needs. Certainly, it is a complete self-contained product. You don’t need any complex assembly at all. However, unlike the above models, it is not a finished and ready-to-use model. You have to connect it with the included solar panels before starting to produce the solar energy to power your off-grid life.
As its title says, it could offer you 135 Amp hours of electricity to run a variety of your devices and gadgets. At the peak, it would go up to 4000 watts. The solar generator kit features a pair of 100W solar panels, which are enough to charge the included battery in some hours.

Of course, you must buy a solar charger separately with the machine to make it a complete solar generator. What Goal Zero recommends is one of its Boulder solar panels.
