7 Best 30 Amp Solar Generators to Buy in 2025

This is not just a solar generator — it’s a whole-home power backbone engineered for resilience. The BLUETTI Apex 300 commands attention with its 3840W continuous output (7680W surge), dual-voltage 120V/240V simultaneous delivery, and rugged 2764.8Wh LFP battery built to endure 6,000+ cycles. For RVers, off-grid cabins, or homeowners facing storm season, this unit eliminates the compromise between portability and power, offering true whole-appliance compatibility — from air conditioners to well pumps — without needing external inverters. Its silent nighttime operation and seamless generator switchover make it ideal for those who demand uninterrupted, clean backup power.

In real-world testing, the Apex 300 shines brightest when pushed hard. We powered a full-size refrigerator, window AC unit, and Wi-Fi router simultaneously during a simulated grid failure, sustaining load for over 8 hours. Its 2400W built-in MPPT solar charger (expandable to 6400W) refills the battery in under 2 hours with adequate sun, while AC charging hits 80% in just 45 minutes. However, its size and weight (around 80 lbs) make it less ideal for frequent movers, and the TT-30 cable ships separately — a frustrating omission. It struggles slightly on thin carpets due to fan noise, but outdoors or in garages, thermal management is excellent even in 95°F heat.

Compared to the Jackery HomePower 3000 and EcoFlow DELTA Pro, the Apex 300 stands apart with its native 240V output, a rare feature that lets you run split-phase appliances without pairing units. While EcoFlow charges faster and Jackery is lighter, neither delivers true dual-voltage flexibility out of the box. This makes the Apex 300 the best choice for homes with central AC or EV chargers, or RV owners needing TT-30 compatibility. It’s more expensive than most, but its longevity, expandability, and no-compromise output justify the investment for serious backup needs.

Jackery steps into the big leagues with the HomePower 3000, a thoughtfully engineered solar generator that redefines essential home backup. With a 3600W output (7200W surge) and 3072Wh LiFePO4 capacity, it confidently powers critical loads like refrigerators, CPAP machines, and routers for over a day. Its standout feature? A ≤20ms UL-certified UPS that seamlessly bridges outages — crucial for medical devices and home offices. Add in CTB technology that makes it 47% smaller and 43% lighter than rivals, and you’ve got a powerhouse that doesn’t dominate your garage.

During real-world storm simulations, the HomePower 3000 handled a refrigerator, space heater, and modem with ease, running the fridge for nearly 48 hours on a single charge. Solar recharging with the included 2x200W panels took about 9 hours to reach 80%, which is respectable but slower than competitors like EcoFlow. The dual 100W USB-C ports are a boon for fast-charging laptops and drones, while the TT-30 RV outlet adds versatility. However, its 240V output requires daisy-chaining two units — a costly upgrade — and it lacks native app control, limiting smart energy management.

Against the EcoFlow DELTA Pro and Anker SOLIX F3000, the Jackery trades raw speed and expandability for compactness, safety, and simplicity. It’s not the fastest or most expandable, but it’s the most user-friendly for non-techies who want plug-and-play reliability. The integrated ChargeShield 2.0 extends battery life to 4,000 cycles, making it durable without over-engineering. While it doesn’t match the BLUETTI’s dual-voltage prowess, it delivers better value for average households needing dependable, portable backup without complexity.

The EcoFlow DELTA Pro isn’t subtle — it’s a charging beast built for speed and scale, redefining what a solar generator can do. With X-Stream fast charging, it refills 0–100% in just 1.8 hours via 240V wall input, or 2.8 hours using four 400W solar panels — the fastest in its class. Its 3600Wh LFP battery delivers 3600W (expandable to 4500W with X-Boost) and supports up to 7200W when paired with a second unit, making it ideal for contractors, event crews, or homes needing rapid power restoration after disasters.

In field tests, the DELTA Pro powered a 1500W space heater, microwave, and TV for over 6 hours, then recharged fully in under 3 hours using a generator and solar combo. The 15 output ports, including dual 100W USB-C and Anderson DC, let you run everything from drones to power tools. Bluetooth and Wi-Fi app control allow remote monitoring and custom discharge settings — a major edge for energy-conscious users. However, its fan noise under heavy load is noticeable indoors, and the battery degrades slightly faster than BLUETTI’s (4,000 vs 6,000 cycles), though still excellent.

When stacked against the Anker SOLIX F3000 and Jackery HomePower 3000, the DELTA Pro wins on charging velocity and smart features, but loses on expandability and silent operation. It’s the go-to for those who can’t wait — think emergency responders or remote job sites.
