Why Power Independence Matters Now
Homeowners across the U.S. face rising energy bills, increasing blackouts, and a growing demand for reliable power backup. Whether it is the storms knocking out grids in Texas, rolling blackouts in California, or just the need to save some bucks on the monthly utility bills, it is evident that energy independence is no longer a luxury; it is a requirement.
And this is where the WALRUS G4 Plus Whole-Home Battery System steps in. This behemoth of an energy system packs 23kWh of energy storage, a 16.5kVA inverter, and a UPS backup seamlessly to ensure that your lights stay on, your gadgets stay charged, and your home keeps running, whether connected to the grid or fully off-grid.
Even more exciting is that you can order this premium solar battery backup system for $5,199—originally $12,000—so take advantage of this exclusive 55% discount, only available at BatteryEVO.com.
Why Energy Independence Is the Smartest Choice in 2025
The U.S. power grid is under strain with demand rising, infrastructure aging, and natural disasters causing outages. Outages have become more frequent and costly. Old-fashioned gas or diesel generators are not merely noisy and polluting; they also demand costly fuel and maintenance.
A whole-home battery system like the WALRUS G4 Plus offers:
- Peace of mind during blackouts with instant UPS backup.
- Long-term savings by reducing electric bills by up to 95%.
- Eco-friendly energy storage without the fumes of a generator.
- Flexibility for solar adopters who want to store excess energy for later use.
Comparing it with popular competitors like Tesla Powerwall or Generac, the WALRUS G4 Plus offers superior capacity, inverter performance, and unmatched affordability.

Big Savings Breakdown: Why $5,199 Is a Steal
At its list price of $12,000, the WALRUS G4 Plus already offered more storage and power output than most competitors. However, at $5,199, it is among the most affordable whole-home energy storage systems available on the U.S. market today.
Let’s compare:
- Tesla Powerwall 2: 13.5kWh capacity, ~$9,200 per unit, often requires two for whole-home backup.
- Generac PWRcell: 18kWh capacity, ~$10,000 with installation.
- WALRUS G4 Plus: 23kWh capacity, $5,199 on sale.
That means you would be paying less than $226 per kWh for storage compared to $680+ with Tesla. Factor in the ability to save up to 95% on your electric bills and it becomes an investment that pays for itself.
Versatility for Every Home: Grid-Tied, Off-Grid, or Hybrid
The WALRUS G4 Plus is built for flexibility:
- Grid-Tied Homes: Store cheap electricity during off-peak hours, use it during expensive peak times.
- Off-Grid Living: Power remote cabins, farms, or rural homes without relying on the grid.
- Hybrid Setup: Pair with solar panels for full independence, or connect to a generator for backup charging.
- Built-in UPS: Instantly switches to battery power during outages—no manual restart required.
Whether you’re preparing for emergencies or cutting ties with the utility company, this system delivers.
