Coming soon!


The new solar battery for private homes, smaller businesses and housing associations.


  • Leverage all the solar power you generate
  • Pay less for energy
  • Gain energy independence
  • Track your production and use via the XOLTA app


Increasing tariffs on electricity with greater variability in price throughout the day are expected. Be prepared with a XOLTA solar battery, which is designed to – in the near future – be able store and use electricity when it benefits you most.


XOLTA solar batteries should be placed outside. You decide. The LFP (Lithium Iron Phosphate) battery cells are mounted within a galvanized steel box covered by an aluminum shell. LFP is one of the safest battery types on the market. XOLTA batteries are controlled by a Battery Management System (BMS) from Lithium Balance, one of the world’s leading suppliers of functional safety in battery systems. All this ensures an extremely high-quality battery solution.

Unlike most batteries on the market, a XOLTA solar battery is an all-in-one battery. A single box contains all battery units, including the battery inverter. On top of that, the attractive design allows for hanging placement in a visible location. With the choice of two colors for the battery frame and front, you can tailor the battery’s appearance to your preference.

The battery is installed by a XOLTA-approved, authorized installer. The installation process itself takes a few hours.

The XOLTA app gives you a comprehensive overview of the power produced by your solar cells, as well as how much of your total electricity use comes from energy you produce. You can also see exactly how much money and CO2 emissions you save.


The XOLTA BAT-5 and BAT-10 will be on the market in the beginning of 2021. If you want to be updated with news about the new batteries, fill out the form below.

Testing and quality

XOLTA’s solar batteries are designed for outdoor installation.
Placement outdoors demands exceptional robustness, since the battery must operate in all types of weather – heat, cold, rain and snow.
We thoroughly test our products to be sure that every single XOLTA solar battery delivers what it promises:
All the benefits of an intelligent solar battery system
The ability to get the most out of your solar cell investment

What and how do we test?

XOLTA’s solar batteries undergo a range of rigorous tests. They also contain components that themselves have had to meet stringent testing requirements.

Before any battery is shipped to consumers, it must pass final testing scrutiny at our laboratory facilities in Smørum, Denmark.


The battery must perform perfectly in all weather conditions typical for the climate in which it operates. That’s why we expose the battery to severe frost and extreme heat – to ensure that all battery parts can handle the Nordic climate.

As a rule, a battery discharges fine below freezing but has a harder time charging at very low temperatures. We therefore test that the specially designed heating plates maintain an ideal battery pack temperature. This ensures that the battery also can charge on a cold, sunny winter day.

What’s more, the battery must be able to get rid of heat, as high temperatures can affect the battery cells and shorten their lifetime. That’s why we also test that the silent, convection cooling system is working appropriately.


Nordic weather offers many days of high humidity, rain and snow. Humidity can result in condensation that harms vital battery parts. But the battery’s inner box of galvanized steel hermetically seals off these vital parts, preventing humidity from entering.

We expose the inner box to a humid environment to be 100% sure that it protects the inner components of the battery from condensation.

Radiant heat

No matter where a XOLTA battery is placed, the outer shell must never have a surface temperature high enough to burn oneself on. The shell must also protect the vital parts inside the battery’s inner box.

We expose the battery to high radiant heat and test that the outer shell does what it should: ensure a comfortable surface temperature and protect the inner box from overheating.


The last test we conduct ensures battery robustness.

We need to make sure that the battery can handle transportation from production to storage and from storage to consumer. That’s why we put the battery through a vibration test.

We also test that the battery can withstand bumps and blows. It must be able to handle being hit by any kind of ball if placed in the yard. It must be impossible to break apart. And even the smallest, most curious fingers should not be able to find their way to the battery.

By the way, the XOLTA solar battery system is silent and contains neither a compressor nor a fan.
