Addressing energy challenges with HEIM

Combat rising costs with smart energy storage

Electricity prices are rising and homeowners are often struggling with high energy bills. With the XOLTA HEIM system, you can store excess solar energy generated during off-peak hours and use it during peak hours, significantly reducing your dependence on expensive grid power. This not only lowers your monthly bills, but also protects you from price fluctuations.

Maximize your solar investment

It is not uncommon for solar panels to generate more energy than your home can immediately consume. Without proper storage, this excess energy flows back into the grid — often with little benefit to you. The XOLTA HEIM captures this excess energy and stores it for when you need it most. This ensures that you maximize the benefits of your solar system and reduce overall energy waste.

Enhance your energy independence

Many homeowners face the challenges of an outdated and unreliable power grid that can lead to unexpected outages and an unstable power supply. By integrating the XOLTA HEIM, you gain better control over your energy needs, reduce your dependence on the power grid and increase your home’s resilience to external power interruptions.

Accelerate your solar returns

The initial cost of solar panels can be a barrier to their adoption. However, the XOLTA HEIM increases the economic return on your solar systems by allowing you to store and strategically utilise your solar energy — not only lowering your bills, but also potentially making money through smart grid contributions. This faster ROI makes solar investments more attractive and financially viable.
