The X1 is a modular home battery you build to the size you need, and it keeps working in conditions that knock other batteries around. You start with the power module and one 5kWh battery module, then stack more battery modules to reach the capacity that suits your place, from 5kWh up to 30kWh in a system, and you can run two systems in parallel for more.
Temperature is where the X1 stands apart. The battery modules hold their rating from -20°C right up to 55°C, where a lot of batteries quietly lose capacity in extreme heat or cold. For Australian roofs, garages, and walls that bake through summer, that’s the spec that matters. Output does ease back once it gets above 45°C, so in a hot spot your installer will factor that in, but the working range is wider than most.
It does proper backup. When the grid drops, power switches over in under 10 milliseconds, fast enough that your appliances don’t notice. The hybrid power module is efficient too, up to 97.6%, so very little of your solar is lost moving through the system.
On safety it runs LFP (lithium iron phosphate) cells, the stable, longer-lasting chemistry, with a long list of built-in protections covering overcurrent, overvoltage, over-temperature, surge, and insulation faults. The whole system is IP66 rated against dust and water, runs quietly at under 30dB, and mounts on the floor or a wall, indoors or out. It’s backed by a 10-year warranty.
