4 Panels vs. 8 Panels: Which Solar Accessories Kit is Right for You?

Choosing the Right Solar + Battery Setup

Energy bills are rising across America for the homeowner rather than the banks-they have grown due to the frequent occurrence of blackouts and the need for reliable back-up power. With heat waves across California, storms in Texas, or, even, the rising demand for environmentally-friendly energy, a whole home battery system with solar integration is no longer a luxury but a must-have.

Here at BatteryEVO, we made the WALRUS G4 Plus All-in-One System for providing true energy independence for the family. It acts as guardian-like protection for your home or business from being run without any interference, whether in the grid or outside it, with independence being interpreted in the huge lithium battery of a 23kWh capacity, an inverter working at 16.5kVA, and with a solar charger of the 8kW rating. For WALRUS G4 Plus, there are two other options for solar accessory-modern solar 4-panel kits or 8-panel kits-to allow for even better flexibility.

The question, then, is which is good for you? An analysis of the benefits of both options, a comparison of both kits, and help in deciding which solar + battery set meets your lifestyle and budget will follow.

Why Solar + Battery Systems Are the Future

For decades, generators were called upon during blackouts. They are noisy and depend on fuel and maintenance. As for lithium battery-driven backup systems, they are quite and very efficient.

The WALRUS G4 Plus with Solar Accessories Kit combines solar panels with a high-capacity battery to deliver:

• Continuous blackout protection without refueling.
• Energy savings by charging during off-peak hours and using stored power at night.
• Off-grid power independence, whether for your main home, cabin, or small business.
• Peace of mind backed by a 10-year warranty and lifetime technical support.

By pairing your battery with either 4 or 8 solar panels, you can generate clean power daily and reduce reliance on the grid—even during high demand periods.

The 4-Panel Solar Accessories Kit: Compact, Affordable Power

Sale Price: $6,159 (Regular $15,800)

The 4-panel kit is the ideal entry point for families or businesses who want the benefits of solar + battery backup without a large upfront investment.

✅ Benefits of the 4-Panel Kit

• Lower initial cost — makes solar adoption more affordable.

• Seamless integration — works directly with the WALRUS G4 Plus battery and inverter.

Example Use Case

A family staying in a medium-sized house can use the 23kWh storage capacity for evening use and in emergencies. With 4 panels, they generate enough power to charge the battery daily and thereby provide blackout protection for the essentials.

Best For: Budget-conscious homeowners, vacation properties, RV users, and anyone who wants backup power for essentials.

The 8-Panel Solar Accessories Kit: Maximum Independence

Sale Price: $6,959 (Regular $16,800)

Then for households or businesses that use power more voraciously, the 8-panel kit doubles the size of solar input thus allowing faster charging of the WALRUS G4 Plus battery.

✅ Benefits of the 8-Panel Kit

• Greater energy production — more power captured daily for bigger savings.
• Faster battery charging — keeps your 23kWh system topped up, even on cloudy days.
• Reduced grid dependency — power more appliances directly from solar.

Support for high-consumption homes — perfect for HVAC, multiple fridges, and heavy electronics.

• Future-proof investment — ensures long-term resilience as energy use grows.

Example Use Case

A big family with multiple appliances, air-conditioning, and security systems can rely on the 8-panel kit to generate enough power every day to support almost full home usage. During prolonged outages, it keeps the house running well at minimal inconvenience.

Best For: Larger homes, businesses, off-grid properties, and anyone looking for maximum energy independence.
