Stop Waiting for the Grid

Deliver 40kW Fast Charging Today via Your Existing DC Infrastructure

Have you hit the “Grid Wall” effect? It is the #1 reason for EV charging projects  to fail. Traditional AC-coupled chargers require massive capital to upgrade local transformers and involve “double-conversion” energy losses.

Ampernext changes the paradigm. By keeping the energy in the DC domain from your solar panels or batteries straight to the vehicle, you eliminate the middleman (the AC grid) and the waste.

Our Elevation DC platform allows you to bypass 12-month utility delays and €100k+ grid upgrade fees. Plug directly into your Battery Storage (BESS).

40kW DC-DC EV Charger

The Ultimate Off-Grid & Microgrid Fast Charging Solution

Beyond the "Black Box"

Oposing to “all-in-one” closed systems, Ampernext provides open, secure, and sovereign power electronics and firmware platform, ensuring your infrastructure remains independent and protected.

Built for the Frontiers of Electrification

Solar-Assisted Logistics: Use your warehouse roof as a “petrol station.” Charge delivery vans at 40kW directly from a battery connected to your PV during the day—zero grid cost.

Weak-Grid Firming: Have a site limited to 10kW AC? Use a small battery buffer and our 40kW unit to provide fast charging without a utility upgrade.

Industrial Microgrids: The perfect “plug-and-play” component for factories moving toward localized DC power distribution.

Technical Overview

The all-new 40kW DC-coupled wallbox is a highly advanced charging solution designed for sites where the grid is either weak or non-existent. By leveraging the latest advancements in smart DC grids, this unit allows for direct-to-battery connection, removing the need for external AC/DC conversion stages.

Whether you are a fleet operator using vehicle-mounted units or a CPO building a solar-powered charging hub, the Elevation DC platform ensures that your energy goes where it belongs: into the vehicle, not into wasted heat.

Revolutionizing Infrastructure: The 40kW DC-Coupled Advantage

Traditional EV charging relies on converting AC power from the grid into DC for the vehicle battery—a process that is increasingly inefficient as grid demand outpaces infrastructure. Every conversion from AC to DC results in heat loss, hardware complexity, and massive capital investment in transformer upgrades.

Ampernext is changing the paradigm. Our 40kW DC-to-DC charger, on the Elevation DC platform, eliminates the middleman. By connecting directly to your DC microgrid or Battery Energy Storage System (BESS), we deliver 97%+ conversion efficiency and zero grid impact.

Why this matters for your site:

  • Bypass the Grid: Deploy 40kW fast charging on sites with limited AC capacity.

  • Reduced CapEx: Avoid the six-figure costs and 12-month wait times for utility transformer upgrades.

  • Native Solar Integration: Capture 100% of your PV energy without the 5-10% loss of traditional inverter chains.

  • Battery Agnostic: Our software-defined power electronics integrate with any battery chemistry or manufacturer on the market.

Don’t just buy a charger. Secure your energy independence

The era of “cheap and easy” grid power is over. Whether you are a BESS manufacturer looking for a European power module partner or a fleet operator tired of utility delays, Ampernext is your path forward.
