How long can I stay off grid?

A question we get asked many times. So we've created a simple calculator to give you some idea of how long your battery will last off grid. It will take into consideration any solar panels you've installed, 12v and 240v usage. Based on the information provided it will recommend a battery size and estimate the number of days use.

Calculate

Cold Protection

Our Core and Elite ranges are built with integrated heat pads, ensuring reliable charging even in extreme temperatures. Unlike some brands, our advanced heat pad technology is placed between every cell, maintaining a consistent temperature across the entire battery for optimal charging performance and longer life expectancy.

Victron Integration

Our Elite range is equipped with advanced CAN-Bus technology, enabling seamless integration with Victron Energy’s suite of CAN-Bus active solutions. This direct communication link ensures full compatibility with Victron’s monitoring and management systems, giving you precise control over your battery’s charging and discharging operations. By connecting directly to Victron services, users benefit from real-time data, enhanced system efficiency, and smarter energy management — ensuring optimal performance and reliability in every application.
