With zero hidden costs and whisper-quiet operation, BatteryEVO’s Walrus G4 PLUS crushes traditional Generac standby generators—outperforming their inverter add-ons, automatic transfer switches, and bulky RhinoCoat aluminum enclosures.
-
Cost & Value: Smarter Investment
Generac home standby generators start at $2,500 and go to more than $10,000, while installation will push prices to $7,000 to over $15,000-including the costs of gas lines, transfer switches, and concrete pads. Add to these costs the fees for professional installation as well as any required permits. Warranty coverage varies on certain products but may incur additional charges for the longer (up to 10 years) warranties.
The Walrus G4 PLUS delivers 23 kWh of storage and a 16.5 kVA inverter for around $6,320. It includes MPPT solar charging, battery, and inverter—all with zero installation fees, zero fuel costs, and no hidden warranty gimmicks. BatteryEVO backs it with a 10-year limited warranty and U.S.-based customer support—all included in the price.
-
Installation & Setup: Zero Hassle
Generac needs to be properly installed, an automatic transfer switch secured with a RhinoCoat™ rust-resistant aluminum enclosure outside tied to gas utilities into your electrical power panel.
The Walrus G4 PLUS is in comparison plug and play:
- Connect using NEMA L14‑50 or SS2‑50P
- Recharge via solar, grid, or expansion with Anderson plugs
- No permits, no pad, no gas hookups—just roll it in and plug it in. Solar arrays tie in at the flip of a switch.
-
Noise & Operation: Total Silence
Even in Quiet Test™ mode, Generacs' larger inverter-type models generate noise levels in the 60 dip-70 dB range, like your vacuum or urban noise. It's a nuisance for overnight operations or neighbors that are close by.
The Walrus G4 PLUS is completely silent—no engine, no exhaust, no sound.
-
Performance & Capacity: Balanced Power
Generac covers 10 kW to 150 kW, utilizing True Power™ low total harmonic distortion (<5%), Automatic Load Management, and dependable three-phase or single-phase configurations. In comparison, the Walrus G4 PLUS.
Offering the Walrus G4 PLUS with:
- 23 kWh battery, expandable to 46 kWh
- 15 kVA inverter for 110/220 V circuits
- 8 kW MPPT solar charging, with easy solar array hookups
- Clean, pure sine wave power—from battery or solar
- App integration for real‑time monitoring and control
Easy expand-solar-full or hybrid-it's your choice.
-
Fuel & Sustainability: Go Green
Natural gas and propane are the fuel sources for Generac, which contribute carbon emissions and are vulnerable during outages because of supply issues. However, they are not renewable resources.
The Walrus G4 PLUS, in contrast, is solar and battery-powered with charging via rooftop solar, grid, or supplemental sources. Hence no fuel means no carbon and guilt on delivery logistics or environment.
-
Maintenance & Reliability: Built to Last
Every single year, Generac engines call for an annual tune-up - oil, filters, spark plugs, batteries, to mention just a few - and they come accompanied by very standard maintenance contracts, and wear on items such as air filters, carburetors, and batteries over time.
Walrus G4 PLUS comes with no moving parts at all, just the battery cells and the wiring along with some electronics. Its BMS protects against voltage/temperature anomalies. Moreover, BatteryEVO protects it under the 24/7/365 U.S.-based customer support-generally the very thing Generac takes care of through third-party dealers.
-
Smart Features & Monitoring
With Generac's Mobile Link, remote alerts and test schedules can be activated, while their Evolution™ LCD will enable self-tests, in addition to offering multilingual menus. However, access is subject to extra subscription fees.
Walrus G4 PLUS takes it a step further:
- Wi‑Fi/Ethernet connectivity included
- Intuitive touchscreen + BatteryEVO app
- Real-time solar input, charge cycles, billing-ready data
- Expandable solar logging, battery metrics
- Use-Cases & Best Fit Scenarios
Scenario |
Generac Standby |
Walrus G4 PLUS |
| Noise-controlled areas | Needs Quiet‑Test or inverter-type but still noisy | Totally silent—perfect for neighborhoods |
| EV charging / home workshop | Up to 150 kW—but pricey & installation-heavy | 16.5 kVA inverter ideal for EVs and tools; scalable units |
| Renters/condos/HOA settings | Often disallowed due to noise & fuel | Portable, quiet, and permitted wherever outlets exist |
| Off-grid or cabin environments | Needs diesel delivery and enclosure | Solar-ready, portable, no fuel logistics |
| Long-term ownership | Up to 20 years (Cummins) but heavy maintenance | No engine downtime; longer battery cycles with easy replace |
-
Warranty & Support: Peace of Mind
Generac offers warranties up to ten years on specific models, but most will require stand-alone coverage plans. RhinoCoat™ aluminum enclosures provide weather protection but may complicate the processing of claims because outside dealer fulfillment is typically turned over to them.
Compatible with a 10-year limited warranty included with the basic package, the Walrus G4 PLUS is scalable through BatteryEVO, with the added assurance of 24/7 U.S. customer support. No need for third-party contractors—there’s no ambiguity regarding the warranty.

FAQs
What generator is better than Generac?
The Walrus G4 PLUS is a powerful alternative to traditional Generac standby generators. While Generac systems often require fuel lines, professional installation, and routine servicing, the Walrus G4 PLUS offers an all-in-one, plug-and-play solar generator with a 23 kWh battery and a 16.5 kVA inverter—completely silent and fuel-free. With renewable energy, long-term savings, and permanent home integration, it’s the smarter choice for modern homeowners.
What are the disadvantages of a standby generator?
Disadvantages of standby generators as Generac are n:
- High upfront and installation cost
- Noise during operation, even with Quiet-Test mode
- Requires fuel (natural gas or propane)
- Ongoing maintenance (oil changes, filter replacements)
- Permitting and HOA restrictions
The Walrus G4 PLUS eliminates these issues by providing silent, fuel-free, and low-maintenance solar backup power.
Is the Generac generator good or bad?
Generac generators are dependable for grid-tied, whole-home backup with automatic transfer switches. But that dependability comes with compromises: fuel reliance, noise, required professional installation, and ongoing maintenance costs.
- Require professional installation
- Depend on fossil fuels
- Are noisy and demand regular upkeep
In contrast, the Walrus G4 PLUS offers a cleaner, quieter, and more cost-effective approach to home backup power with solar integration and smart app-based monitoring.
What is the main problem with generators?
Main points about typical generators are:
- Fuel dependency and emissions
- Noise pollution
- Frequent maintenance needs
- Installation complexity
- Higher long-term ownership cost
The Walrus G4 PLUS addresses these challenges with a battery-based, solar-charging, and silent inverter system, ideal for off-grid, eco-conscious, or noise-sensitive environments.
How many watts to run a house?
A typical U.S. home may require 5,000 to 10,000 watts (5–10 kW) to run essential systems like HVAC, lighting, refrigeration, and electronics. The Walrus G4 PLUS, with its 23 kWh battery and 16.5 kVA inverter, easily supports whole-house backup—including high-energy appliances and EV chargers—delivering cleaner, quieter, and more flexible power than many traditional Generac systems.
