Two ways to store.
One platform.
From the inverter on the wall to the container on the slab — WLF Energy storage spans three platforms: a three-phase inverter family, C&I battery cabinets, and grid-scale containers. One product story, one warranty story, one accountable EU operator.
Tomorrow’s Storage.
Engineered Today.
The next generation of WLF ESS storage is already engineered: up to 25,000 cycles at 80% capacity retention, a −40 °C to +80 °C operating window and 50C discharge — with reduced swelling and improved abuse safety built in.
The next storage generation — longer life, wider range, more energy.
Next-generation ESS storage rated for up to 25,000 cycles with 80% capacity retention at end of life.
Specified from −40 °C to +80 °C, so one storage platform serves Nordic winters and southern-European summers alike.
Cells rated for 50C discharge — instant power delivery for backup hand-off, grid firming and frequency response.
Reduced swelling and improved abuse safety — engineered to Hazard Level 2 across the full 25,000-cycle life.
One platform,
three roles.
One engineering standard, the same EU operator, one warranty story — from a panel on the wall to a megawatt park on the slab. Pick the layer your site needs.
Built for the wall.
Built for the slab.
From a 6 kW inverter in a German home to a multi-megawatt container park, every WLF format is engineered, integrated and warranted to the same WLF standard. Modular and scalable, it grows with the site — and one accountable EU operator stands behind all of it.
The same long-cycle engineering standard runs right across the family — wall inverter, C&I cabinet and grid-scale container. One safety story, one datasheet language, no surprises at integration.
Start with a single battery-and-inverter setup and stack up from there. Cabinets rack together, containers parallel into MWh and GWh parks — the same kit, just more of it.
One warranty, one named operator, one point of contact — from order to commissioning to year fifteen. Monitoring, diagnostics and support without the finger-pointing.
One range. Every site.
From a wall in a German home to a substation on the grid, the same platform and the same operator follow the energy wherever it needs to sit.
Peak-shaving, demand charge management and arbitrage for factories, logistics depots and campuses — liquid-cooled and rack-stackable.
Bankable energy parks, firming and ancillary services — battery, EMS and PCS integrated per container, paralleled into MWh and GWh.
Resilient, self-balancing energy for remote sites, island grids and critical facilities — one platform from the inverter to the container.

Tell us the format you need (wall-mount inverter, C&I cabinet or grid-scale container), the energy and power you are after, and the site. We come back with a sized configuration, a costed quote and a delivery plan.
hello@wlfenergy.deA real site with real numbers — home, commercial building, depot or substation. We size around how it will actually be used, not off a spreadsheet.
Energy, power, footprint, grid connection and backup needs. We pick the right format and the right way to wire it all together.
You get a sized storage configuration, a costed quote and a delivery plan — straight from a named operator, with a 48-hour turnaround.
