BOLT-10

More and more project sites are running into grid-related issues: no connection, insufficient power, or years-long wait times. The BOLT trailer solves this problem by combining battery storage and DC fast charging in a single mobile trailer. With a storage capacity of up to 1,044 kWh and an integrated fast charger of up to 130 kW, you can instantly set up a fully functional charging station anywhere, without the need for grid upgrades.

The system is trailer-mounted and plug-and-play: delivered today, operational today. Ideal for construction sites, logistics hubs, loading yards, and locations without (sufficient) grid connection.

Fleet & Equipment Manager Construction company

"We need far fewer diesel generators on the construction site. Combined with battery storage, we now always have a reliable and sustainable power supply, no matter where we're working."

Farmer Dairy farmer

"Our solar panels are really paying off now! With Boltainer batteries and BBT software, we use our own electricity whenever it suits us and save a lot on feed-in tariffs."

Facilities Manager Industrial sector

"Thanks to Boltainer, we've reduced our energy costs by over 30% and are no longer subject to grid restrictions. Our production is running more efficiently than ever!"

PEACE OF MIND THANKS TO RECOGNIZED CERTIFICATIONS

IEC 62933-5-2

An international standard that ensures the safety and reliability of energy storage systems.

PGS-37-1

Dutch guideline with strict requirements for fire safety and risk management.

THEY SEE THE RESULTS

"Our wind energy is now truly working for us instead of for the grid. Whereas we used to feed cheap electricity back into the grid, we now store it smartly and use it when it benefits us. That gives us peace of mind, security, and extra income."

The results so far:

  • Wind energy stored and used locally
  • Generate extra income through smart energy market trading
  • Relief of the network connection
  • Real-time insights with BBox software

Are the inverters built into the container?

Yes, on the BOLT trailer, the inverters are built into the container as standard.

Turn negative electricity prices into profit with the BOLT trailer

The electricity market is changing rapidly. In 2021, there were 70 hours of negative electricity prices. By 2024, that number had already risen to more than 450. That means: if you’re still feeding power back into the grid now, it’s costing you money instead of earning you any. With the BOLT trailer, you can turn this around. This smart battery stores your excess solar energy and feeds it back into the grid when prices are favorable. The result? More control over your energy, lower costs, and maximum return on your solar panels. That’s smart storage and smart savings.
