EcoFlow Delta Pro Alternative | Walrus G4 Plus Offers More Capacity, Smarter Features

In the ever-changing ecosystem of energy, the right home battery system is a necessity rather than a luxury. Between climbing utilities, climate uncertainty, and the necessity of sustainable energy independence, home owners are looking at solutions that can put such into consideration on reliability. The two heavyweights in this space are the Walrus G4 Plus vs EcoFlow Delta Pro. These are both heavy-duty systems, but they are intended for different applications altogether. In this detailed comparison, we will expound on why the Walrus G4 Plus stands head and shoulders above the competition.

For the sake of completeness, we can also throw some mention to EcoFlow DELTA 2, DELTA 2 Max, EcoFlow RIVER 2 Pro, and EcoFlow DELTA Pro Ultra, all available in this mix. None, however, provide the complete home energy solution that Walrus does. Even the Walrus Pacific was very good, but the G4 Plus took over its shine.

Walrus G4 Plus vs EcoFlow Delta Pro

EcoFlow Delta Pro is a portable power station made for users who want mobility-the kind suitable for camping, RV, small houses, and emergency situations. It has a base capacity of 3.6 kWh with an AC output of 3.6 kW (7.2 kW for surge) and works efficiently when lightweight backup is required.

In contrast, the Walrus G4 Plus is a movable home battery solution designed for whole-home energy independence. It starts at 23 kWh and expands up to 90 kWh. With output power 16.5 kVa, it supports everything from air conditioners and freezers to EV charging and multi-circuit backup.

1. Battery Capacity & Scalability

EcoFlow Delta Pro:

Walrus G4 Plus:

• 16.5 kVA (13 kW) AC output, with 23 kWH capactiy
• Handles heavy appliances like HVAC units, well pumps, and even EV Level 2 charging

For entire-home backup and high-powered tools, the Walrus G4 Plus truly stands out.

3. Charging Methods & Efficiency

EcoFlow Delta Pro:

• AC wall charging
• Limited solar input (~1600W)
• Generator and EV adapter compatibility, but with neutral-loop GFCI issues reported by users

Walrus G4 Plus:

• Supports MPPT solar charging up to 16.8 kW
• Compatible with 3–12 kW gas generators
• Smart time-of-use charging via grid integration

Walrus G4 Plus is truly future-resistant and far more efficient for longer off-the-grid applications.

4. Smart Features & Ecosystem

EcoFlow Delta Pro:

• Works with Smart Home Panel, but limited to specific setups
• No built-in AI management

Walrus G4 Plus:

• AI-powered energy saving plans
• Fully integrated with smart homes
• Includes Smart Home Panel 2 with single-circuit control
• Storm-ready backup mode with 20 ms switchover

A truly intelligent energy management experience from Walrus.

5. Build Quality & Durability

EcoFlow Delta Pro:

• Plastic build, more suitable for indoor or RV use

Walrus G4 Plus:

• Industrial-grade casing
• IP54 rating for dust/splash protection
• Operative in wide temp ranges (−4 °F to 113 °F)

Built with real-life considerations in mind, the Walrus is made for real-life applications.

6. Portability vs Performance

EcoFlow Delta Pro:

• Compact and wheeled
• Best for RV, camping, or light backup

Walrus G4 Plus:

• Not intended for travel
• Designed for whole-home backup and high-demand setups

If you're talking mobility, look toward the Delta Pro. For performance-based applications, nothing beats the Walrus G4 Plus.

7. Return on Investment

EcoFlow Delta Pro:

• Cheaper upfront
• Higher cost per kWh

Walrus G4 Plus:

• May qualify for federal solar tax credit (30%)
• Saves up to $3,600/year on energy bills
• 2.5-year payback period in smart grid scenarios

The Walrus G4 Plus is all for saving money in the long run and real energy independence.

8. Use Case Comparisons

Conclusion: Why Walrus G4 Plus Wins

BatteryEVO-exclusive, the Walrus G4 Plus isn't merely a home battery, but a 360° energy solution. In terms of capacity, smart features, solar support, and long-term savings, it all but eclipses EcoFlow Delta Pro in just about every metric that matters.

For insulation against energy independence, reliability, and long-term ROI, Walrus G4 Plus is the one for the year 2025.

FAQs

Can EcoFlow power a washing machine?

3.6 kW AC output allows the EcoFlow Delta Pro to run a regular washing machine. However, for maximum watts running at the same time, such as heavy-duty appliances operated simultaneously, Walrus G4 Plus would make a better choice with its 7.2 kW-21.6 kW scalable output that is perfect for whole-home backup.

Should I choose EcoFlow for home backup?

EcoFlow actually offers some good portable power stations for RVs or camping. However, their Walrus G4 Plus model from BatteryEVO gives such households wanting energy independence, better smart solar integration, and higher battery capacity an upper hand compared to EcoFlow with up to 90 kWh expandable storage and AI-powered energy plans.

Who is a competitor to EcoFlow?

Among major EcoFlow competitors include Anker Solix F3800 Plus, Walrus Pacific, and the advanced Walrus G4 Plus. Of these, BatteryEVO's Walrus G4 Plus clearly excels with smart grid optimization, LFP battery chemistry, and PowerPulse EV charging compatibility.

Is the EcoFlow Delta Pro noisy?

EcoFlow Delta Pro is a relatively quiet unit, considering the distance from which it would normally run. However, the Walrus G4 has X-Cooling thermal control with whisper-quiet 30 dB operation; hence it is an extremely quiet option for homes.

What is the lifespan of the EcoFlow Delta?

Actually, the EcoFlow Delta Pro makes use of LiFePO4 (LFP) battery chemistry that has a cycle life rate of around 3000 cycles. Likewise with the Walrus G4 Plus, it also provides a life cycle of more than 3000 with much better weatherprroofing (IP54 rating) and off-grid compatibility, which makes for a nice long-term investment.
