EF ECOFLOW DELTA 2
The DELTA 2 offers 1024Wh LiFePO4 capacity with 1800W AC output and 100W USB-C for fast charging. It supports 0-80% in about 50 minutes and 0-100% in roughly 80 minutes when connected to AC power, making it a strong choice for quick restoration after outages. Its modular approach allows expansion from 1kWh to 3kWh, which is beneficial for smaller homes or frequent van-life scenarios. With its accessible power kit, it serves as a versatile backup for essentials and is compatible with optional solar panels for extended off-grid capability.
EF ECOFLOW Delta Pro Kit
The Delta Pro establishes a high-capacity home backup system with a 3600Wh LiFePO4 battery and transfer switch compatibility. This kit is designed for substantial home energy storage, enabling prolonged outages with growth potential through extra batteries or smart generators. The transfer switch integration helps power critical circuits during outages, effectively turning the Delta Pro into a home-energy hub. It offers flexible AC outputs and the option to scale up to 25kWh when paired with extensions, making it suitable for larger homes or multi-room critical-load protection.
OUPES Mega 1
The Mega 1 provides 1024Wh of LiFePO4 capacity with 2000W AC output and 4500W peak. It also supports expansion up to 5kWh with additional batteries. This unit balances portability with power, suitable for home backup, camping, and emergency use. It features rapid charging options and a UPS function to maintain continuous operation of essential devices during outages. Its modular design suits households seeking scalable power without large, dedicated storage installations.
OUPES Exodus 1200
The Exodus 1200 packs 992Wh capacity with three 1200W pure sine wave outlets and a peak of 3600W. It includes a 140W USB-C port and UPS features, enabling reliable power for essential devices during outages. Its modest size makes it suitable for apartments or smaller homes while still providing enough capacity to cover essentials like fridges or CPAP machines during extended outages. The device is described as versatile for camping and home backup, with multiple charging ports to support simultaneous devices.
Buying Guide
- Power needs: Assess daily loads and peak surges. Homes with refrigerators, sump pumps, or HVAC will require higher continuous output and surge capacity.
- Storage capacity: Choose battery capacity that aligns with outage duration you anticipate. Higher watt-hours extend the time between charges.
- Expandable systems: If you plan to scale, select units that offer expansion batteries or modular configurations to reach 3kWh–25kWh+ without replacing the core unit.
- Battery chemistry: LiFePO4 offers longer life, better thermal stability, and wider operating temperatures, which improves reliability in home backups.
- Charging speed: Consider AC fast charging versus solar input. If sunlight is limited, faster AC charging reduces downtime between outages.
- Backup features: UPS capability, transfer switches, and multiport outlets improve the resilience of home-critical circuits and appliances.
- Portability vs. permanence: Portable units suit apartments or RVs, while larger, expandable systems are better for whole-home backups when installed with a transfer switch.
- Solar integration: Check compatibility with your existing solar panels and inverters. Some systems include solar panels; others require separate purchases.
- Reliability and warranty: Look for brands with proven track records, long warranties, and accessible customer support for after-sales service.
- Tax incentives: In the U.S., residential clean energy credits can help offset costs; verify eligibility and expiration dates in your state or federal program.
