Jackery HomePower 3600 Plus Portable Power Station
The Jackery HomePower 3600 Plus delivers 3600W of continuous output, with 7200W in parallel when paired. Dual voltage support (120V and 240V in parallel) and a 3584Wh base capacity make it a strong option for powering pumps, heaters, and large loads during outages. Expansion to about 21kWh per unit, or 43kWh with multiple units, supports longer outages for small homes. Best for households needing robust, scalable backup power and straightforward plug-and-play operation.
Best for: Homeowners seeking a high-capacity, scalable solution that can be expanded with additional units. Caution: expansion adds cost and requires planning for parallel connection.
Jackery HomePower 3000 Portable Power Station
The 3000 model offers 3600W continuous output (7200W surge) with a 3072Wh capacity and a built-in UL-listed UPS. This ensures seamless transfer for essential devices like refrigerators, routers, and security systems during outages. The unit provides multiple ports (AC, USB-C, USB-A, DC) plus a TT-30 RV port for easy outdoor and RV use, making it a versatile home-and-road power solution. Best for: Essential-load backups with reliable transfer. Caution: While robust, it has a lower expansion ceiling than larger systems.
EF ECOFLOW Delta Pro
The Delta Pro is designed for serious home backup, with 3600Wh LiFePO4 capacity and expandable storage up to 25kWh or more when paired with extra batteries or smart generators. It supports 7200W when two units are connected, and offers 15 output methods, including USB-C, USB-A, multiple AC outlets, DC, car, and Anderson ports. Best for: Homes needing high-output, scalable backup with flexible charging options. Caution: The system complexity and expansion requirements may demand planning for optimal configuration.
Anker SOLIX S2000 Portable Power Station
The Anker SOLIX S2000 packs 1500W continuous output and a 2010Wh LiFePO4 battery. It excels for long fridge backups and general emergencies, with a 10,000-cycle battery life and a compact footprint relative to its capacity. Best for: Fridge-backed emergencies and compact, portable home backup. Caution: Not as large-scale as the Delta Pro Series when facing prolonged outages.

The Delta 2 offers 1024Wh LiFePO4 capacity with 1800W continuous output and 15 outlets per unit, making it versatile for home backup and outdoor use. It supports 0-80% in 50 minutes charging and 0-100% in 80 minutes with AC input, and can be expanded with additional batteries. Best for: Fast charging and flexible, mid-sized backup. Caution: Smaller capacity than the Delta Pro, so less suited for long outages of larger homes.
MARBERO 237Wh Solar Generator
Note: MARBERO offers a compact 237Wh kit with a foldable 60W solar panel. It’s best for basic device charging and light off-grid use. Best for: Small-device emergencies and campers needing a lightweight, lower-cost option. Caution: Limited capacity and power for larger home loads.
Buying Guide
What to consider when choosing a solar generator for home use:
- Power output needs: Assess essential loads (refrigerator, lighting, wifi, medical devices) and calculate total wattage. Higher continuous wattage supports more simultaneous devices.
- Battery capacity and expandability: Larger capacities withstand longer outages; expandability helps future-proof for growing power needs.
- AC vs. DC and port options: Ensure the unit provides the outlets you rely on, including USB-C for devices and RV-ready ports if you camp or park at home.
- Charging speed and sources: Fast AC charging and solar recharging enable quicker return to operation after an outage. Consider units compatible with additional solar panels.
- Temperature tolerance and durability: Look for high-temperature tolerance and low-temperature operation for crisis reliability in different climates.
- Safety and lifecycle: Battery chemistry (LiFePO4 is common for stability) and expected cycle life influence long-term performance and safety.
- Setup and maintenance: Prioritize plug-and-play designs without complex installation, especially for non-technical users.
- Budget and space: Weigh upfront cost against expansion needs and the physical footprint of the system for home use.
