After a list of briefcase solar generators, I would like to talk about a series of heavy duty solar generators here. Sure, heavy duty solar generators may not be much good for portable use. So you can’t take one for individual camping trips. Meanwhile, they are nice for home, work sites, tailgating, RVing, group camping, or emergency. However, you get most bigger solar generators with durable wheels and carrying handles. Therefore, you can drag them on various surfaces. In that sense, they are portable too.

Heavy Duty Solar Generators for Off-grid Power

There is a big variety of large solar generators. Some models are basically solar-enabled power stations only. In that case, you might need to buy separate solar panels. Meanwhile, some are just DIY solar generator kits. That may include only major components. And you will need to buy more things in addition and put them together to build full off-grid solar solutions. Above all, you have rare models with standalone and integrated solar panels. Those are quite convenient for camping and other outdoor uses.
