Batteries for business

One cabinet, 211 or 261 kWh. Connected and ready.

Battery, inverter, cooling and fire suppression in one outdoor cabinet. We work out which size fits your consumption, arrange installation and grid connection, and stay with the project until it runs.

The problem

Your power costs most exactly when you need it.

  • Peaks

    Every peak above your contracted capacity costs extra, even if it only lasts fifteen minutes.

  • Solar power that leaks away

    What your panels produce too much during the day earns little, and in the evening you buy at a high price.

  • Downtime

    When the grid fails, cooling, pumps and production stop. That damage is often larger than the electricity bill.

The solution

Two sizes, the same design

BESS 211

211 kWh · 100 kW

For offices, greenhouses, cold stores and mid-sized businesses.

  • Switches automatically between grid and island mode
  • Up to 20 cabinets in parallel on the grid, 4 off-grid
  • Suitable for solar and diesel microgrids

BESS 261

261 kWh · 125 kW

For larger consumers, EV charging hubs and rooftop solar with a large surplus.

  • Can start without the grid (black start)
  • Expand with cabinets side by side
  • Operates from −30 to +50 °C

What they are for

Peak shaving
The battery supplies the peaks, so you stay within your contracted capacity.
Using your own solar power
Store the midday surplus for the evening or the weekend.
Backup power
When the grid fails, the most important circuits keep running.
Charging and microgrids
Power EV chargers without a grid upgrade, or a site without a grid connection.

How we work

  1. 1

    Advise

    With your quarter-hourly data or bills we work out which size and how many cabinets you need, and what it saves.

  2. 2

    Engineer

    Placement, cabling, connection to your installation and coordination with the grid operator.

  3. 3

    Deliver

    Transport, installation by a licensed installer, commissioning and remote monitoring.

We send the datasheet and installation manual on request, together with the proposal.
