10 Best Small Solar Generators 2026 in the United States

The EF ECOFLOW DELTA Pro 3 is a robust solar generator standing out in the small-solar-generators category. Its formidable 4096Wh LFP battery offers substantial energy storage, making it a strong choice for home backup during emergencies or for powering essential appliances, like central AC systems or water pumps, for up to 2-4 days. The generator's 4000W power output, expandable up to 12000W with additional units, supports a wide range of devices, while the X-Boost feature ensures even power-hungry appliances can be energized.

The product excels in solar panel compatibility, including two 400W portable panels, allowing efficient harnessing of solar energy. Its impressive range of seven unique and 18 combo charging options, including AC wall outlets and EV charging piles, provide versatility in how it can be powered, reducing reliance on fossil fuels. While portability is emphasized with a handle design, the generator's weight at 115 pounds may limit mobility, especially for solo travelers or camping trips. However, its silent operation, thanks to X-Quiet technology, is a significant advantage for both indoor and outdoor use, ensuring noise is minimal.

Build quality is robust, with IP65-rated CTC battery pack technology and automotive-grade LFP cells enhancing durability and lifespan. The 5-year warranty and strong customer support further enhance reliability, offering peace of mind to users. One area that might be a concern is the generator's size, which may not suit every space, especially in smaller homes or RV setups. Additionally, while the app-controlled system provides convenient monitoring, those less tech-savvy might find the setup initially confusing. This solar generator is ideal for individuals seeking a powerful, reliable source of renewable energy for home use or extended outdoor activities, though potential users should consider its weight and size before purchasing.

The EF ECOFLOW Solar Generator DELTA Pro is a robust option for those seeking a reliable power source for home backup or outdoor activities. Its standout feature is the impressive 3600Wh battery capacity, which, when paired with a 3600W AC output, makes it capable of handling most household appliances. The addition of x-boost technology further enhances its utility by allowing it to power devices up to 4500W.

One of its strengths is the high-efficiency solar panel with a 22.4% conversion rate, ensuring good energy capture even in less-than-ideal weather conditions. The option to fully recharge the generator in about 3.5 hours with three 400W panels is convenient for those on the go. Portability is another highlight, with the solar panel weighing only 16kg and designed to be easily carried.

The DELTA Pro also offers versatility with 15 different outlets, including AC, USB, and DC ports, accommodating a wide range of devices. The inclusion of a smart app allows users to monitor and control the generator remotely, adding an extra layer of convenience.

However, the generator is relatively heavy at 99 pounds, which might pose challenges for portability despite the foldable solar panel design. Additionally, while it has strong solar capacity, the initial setup might require patience, especially since the generator and solar panel are shipped separately.

This solar generator is best suited for those who need a substantial power supply, such as homeowners seeking backup solutions or campers who use multiple power-hungry devices. Its durable build and ease of control through a smart app make it a reliable and user-friendly choice, albeit with some portability trade-offs due to its weight.

The Jackery HomePower 3600 Plus is a powerful solar generator designed mainly for home backup and emergency use, capable of running household appliances like pumps, heaters, and dryers with its strong 3600W output. It offers a large 3584Wh lithium iron phosphate (LFP) battery, which is safe, durable, and can last over 6,000 cycles, making it a long-term investment. One of its standout features is the ability to expand capacity up to 43kWh by linking multiple units, supporting longer power needs for a small household.

This generator includes two 200W solar panels compatible with the unit, allowing clean solar charging that can fully recharge the battery in about 4 hours under good sunlight. It also supports multiple charging methods — AC, solar, DC, and gas generator — providing flexibility depending on your situation. The inverter supports both 120V and 240V, which means it can handle various appliances safely and efficiently.

Despite its high capacity, the device is surprisingly portable for its size, weighing around 77 pounds but designed with wheels and a telescoping handle, making it easier to move around compared to other heavy generators. Its build quality is solid and reliable, with heat-resistant battery cells that protect against overheating and severe weather conditions. While it is easier to set up than some competitors, the solar panels and power station ship separately, so setup requires an extra step. The weight may still be challenging for some users without help, especially if moving it frequently. The price and size might be more than what casual or very light users need. For those seeking a robust, expandable solar generator to keep essential home appliances running during outages or for RV use, the Jackery HomePower 3600 Plus offers excellent power capacity, safe battery technology, and versatile charging options. However, if portability and budget are your top concerns, lighter or smaller capacity models might be worth considering.
