6 Best Alternatives to the EF Ecoflow DELTA Pro 3 Extra (2026)

How each alternative compares

Jackery HomePower 3600 Plus with 4x200W Panels

The Jackery HomePower 3600 Plus weighs 77.2 pounds, which is significantly lighter than the 188-pound DELTA Pro 3. Its compact dimensions of 12.2 by 15.2 inches make it easier to move. It offers 3584Wh of capacity, which is less than the 8kWh base unit. You gain portability and a wheeled design but lose total energy storage. This option suits users who need dual voltage output for specific high-draw appliances without the bulk of larger units. It is ideal if you prioritize lightweight home backup over maximum capacity. The trade-off is less runtime for heavy loads compared to the EcoFlow system.

Anker SOLIX F3800 with Battery and Transfer Kit

The Anker SOLIX F3800 provides 3.84kWh of capacity, roughly half the energy of the DELTA Pro 3. It supports 6,000W output, which exceeds the 4000W rating of the EcoFlow. This unit focuses on quiet operation and offers a longer warranty. You get higher peak power and expandable capacity for future needs. However, you accept a smaller base battery and potentially different physical dimensions. It fits homes needing 6,000W capacity that can be expanded later. This choice is best for buyers prioritizing quiet operation and warranty length over raw output power in the base configuration. It is a strong budget-friendly alternative for whole-home backup.

Jackery Explorer 5000 Plus with Smart Transfer Switch

The Jackery Explorer 5000 Plus delivers 5040Wh of storage, which is lower than the 8kWh DELTA Pro 3 but still substantial. It supports 240V output, matching the dual voltage capability of the original. This model emphasizes high-capacity home backup with massive expandability options. You gain long-term durability and fast solar input speeds. The trade-off is that it may lack the compactness of smaller units while not matching the total kWh of the EcoFlow with extra battery. It suits homeowners needing high-power 240V support and massive expandability. It is ideal for those prioritizing long-term durability and fast solar input over compact size.

EcoFlow DELTA Pro Ultra 7200W Power Station

The EcoFlow DELTA Pro Ultra offers 6144Wh of capacity, which is less than the 8kWh system but still high. It weighs only 70.9 pounds, making it much lighter than the 188-pound DELTA Pro 3. It provides 120/240V output and is certified for whole-house backup. You gain a significantly lighter unit with high-voltage output. The trade-off is slightly less total storage capacity. This fits homeowners who need high-voltage output and certified whole-house backup. It suits those willing to manage a tall unit for maximum power security. It is an excellent choice if you want high power without the extreme weight of the base DELTA Pro 3 with extra battery.

Jackery HomePower 3600 Pro Max 7168Wh

The Jackery HomePower 3600 Pro Max provides 7168Wh of capacity, which is close to the 8kWh DELTA Pro 3. It weighs 74 pounds, significantly lighter than the 188-pound EcoFlow. It offers 240V output for home backup. You gain a lighter, high-capacity energy hub with long battery life. The trade-off is manual switching and potentially less integrated smart features. It fits homes where weight and manual switching are acceptable trade-offs for capacity. This option is ideal for users who need 240V output and long battery life. It is a heavy, high-capacity home energy hub for users who prioritize capacity over the lighter weight of other alternatives.

Anker SOLIX F3800 Plus and Generator 5500

The Anker SOLIX F3800 Plus offers 3.84kWh of base capacity, which is half that of the DELTA Pro 3. It supports 240V compatibility and massive expandability. You gain high-wattage appliance support and flexible power configurations. The trade-off is a smaller base battery and separate components for maximum power flexibility. It fits users who prioritize 240V compatibility and massive expandability over base capacity size. This is ideal for those willing to manage separate components for maximum power flexibility. It is a strong alternative if you need high-wattage appliances and expandable backup storage, accepting a smaller initial battery for greater future scalability.
