As electricity prices surge and storms threaten the grid, thousands of U.S. homeowners are turning to off-grid battery systems for reliable, sustainable energy. This autumn, BatteryEVO invites you to experience true power independence with our Autumn Savings 2025 Event — up to 59 % OFF on select Walrus Home Generator Systems.
Whether you live in the city or off-the-grid, the Walrus battery + inverter system powers your home, RV, and business with clean lithium energy—quietly, safely, and affordably.
Let’s explore how the Walrus Series can help you cut bills, protect your family, and enjoy energy freedom this fall.
Why Autumn Is the Perfect Season to Go Off-Grid
Autumn is the bridge between blazing summer heat and unpredictable winter storms. It’s also the ideal time to invest in energy storage before demand spikes in colder months.
- Prepare for outages: Hurricanes, ice storms, and grid failures can happen anytime. A home battery backup keeps lights, Wi-Fi, and appliances running.
- Save before rates rise: U.S. utilities often raise prices before winter. Going off-grid means locking in your energy cost—$0 per kWh.
- Take advantage of BatteryEVO’s Autumn Savings: With up to 59 % off, your upgrade to reliable power is now more affordable than ever.
When the weather changes, energy should never be a worry. The Walrus Home Generator System makes sure of it.
What Makes Walrus Systems Different from Ordinary Generators?
Traditional gas generators are loud, require maintenance, and depend on fuel availability. In contrast, Walrus battery systems are fully electric, solar-ready, and maintenance-free.

Real Savings & Energy Freedom
Installing a lithium home battery system pays off faster than most homeowners expect.
- No Fuel Cost: Solar + storage = free electricity.
- Lower Bills: Use stored power during peak utility rates.
- Long Lifespan: 6,000 cycles ≈ 10 years of daily use.
- Low Maintenance: Forget oil changes and generator repairs.
Example:
A typical U.S. household spends ≈ $180 / month on electricity.
A Walrus G4 Plus system paired with solar can offset that cost by 70 % or more—potentially saving over $1,500 per year.
Over a decade, that’s $15,000 in savings plus independence from grid failures.
