Product information

Embrace the path to energy self-sufficiency with the Walrus Home Energy System – your all-in-one solution for diverse residential energy needs. With its substantial 30 kWh storage capacity coupled with a robust 12.25k inverter, the Walrus Atlantic is engineered to provide steadfast energy backup, keeping your home illuminated, appliances running, and security systems active, independent of grid reliability.

For solar-equipped households, the Walrus Atlantic serves as a dynamic solar battery, efficiently storing the surplus energy produced during the daytime for your nighttime use or as a standby power reserve, enhancing solar utilization while reducing electricity costs and environmental impact.

The smart versatility of the Walrus is evident in its dual RS 485 ports, Wi-Fi connectivity, and generator interface, assuring effortless integration across various electrical arrangements, from grid-connected to entirely off-grid setups.

But the Walrus Atlantic offers more than just backup; it promises outstanding operational efficiency. Its 95% conversion efficacy and pure-sine wave delivery safeguard your delicate electronic devices, while the dual voltage output options (120V/220V) ensure widespread appliance and tool compatibility. The system’s design, complete with an AC circuit breaker and a ground screw hole, highlights the Walrus Atlantic‘s dedication to consistent performance and paramount safety.
