500 kWh battery container: compact energy storage for businesses

Find the solution that fits your energy project

500 kWh battery container

While the rest of the market has to wait a year and a half for a higher-capacity connection, Boltainer customers with 500 kWh of storage are fully operational within a few weeks. A container of this size is ideal for medium-sized production sites, supermarket distribution centers, SME charging stations, and refrigeration companies that are outgrowing their connection capacity without wanting to immediately move into the MWh class.

Since the entire system is housed in a container, there is no need for structural modifications, permit procedures, or changes to the meter box. The unit is placed on a foundation, connected to the existing infrastructure, and becomes operational as soon as commissioning is complete.

The benefits of this:

High storage capacity within a single system
Suitable for heavy-duty applications
Seamless integration with existing energy infrastructure

Typical applications:

Industrial sites
solar energy projects
companies with high peak loads

Scalable battery storage

Many energy projects grow over time. That is why battery containers are often designed to be modular. When more storage capacity is needed, the system can be expanded with additional containers.

How does a 500 kWh battery container work?

The container holds dozens of LFP battery cells, grouped into modules and racks that are connected to form a single 500 kWh storage system. When your solar panels generate excess power or the grid supplies electricity at a low rate during off-peak hours, that electricity flows into the battery via the power conditioner (PCS).

As soon as the workshop opens, the charging point is activated, or the spot price peaks, the power flow reverses and the container supplies power to your own system. The battery management system (BMS) monitors voltage and temperature at the cell level, while the energy management system (EMS) determines which strategy to follow. To do this, the EMS combines your consumption history, weather forecasts, and current energy prices into a single, continuous charging and discharging decision.

What you end up with is a system that runs autonomously in the background. You set the parameters, and the system follows them.

Benefits of a 1,000 kWh battery

MORE CONTROL OVER ENERGY CONSUMPTION

With 500 kWh of battery storage, you take back control of your energy supply from the grid operator and the daily spot market. You decide when to charge the battery, when to feed power back into the grid, and when to use the electricity you’ve generated yourself.

In practice, this results in the following:

use electricity during off-peak hours instead of paying for it at the most expensive time of day
making full use of your own solar power, even when generation and consumption do not occur at the same time
monthly costs that can be estimated in advance, with no surprises on the annual statement
room for expansion without having to first initiate a network upgrade project

REDUCTION OF PEAK LOAD

For a high-volume consumer connection, the capacity rate is determined by the highest 15-minute peak you generate over the course of an entire year. An unexpected 15-minute spike in February then determines the rate you’ll be charged per kW for the rest of the year. A 500 kWh Boltainer kicks in at precisely those moments and supplies the difference between your actual demand and the agreed upper limit from its own buffer.

What this means for your business:

shipping costs that are falling on a structural basis as the annual peak is being smoothed out
room to grow within the current program without a progression track
less strain on the local grid during peak hours, which benefits your own expansion opportunities
monthly energy costs that are no longer driven by a single spike

BETTER UTILIZATION OF RENEWABLE ENERGY

For many business owners with solar panels, the math is painful: during the day, surplus power is fed back into the grid for a few cents per kWh, only to be purchased back at a much higher rate in the evening. With 500 kWh of storage, you can keep the electricity you generate on your company’s premises, regardless of whether there is production or consumption at that moment.

That translates to:

Maximize the amount of your own solar power that you use yourself, rather than selling it back to the grid for a pittance
independence from political decisions regarding net metering and its phase-out
more energy from the existing PV system, without expanding the roof area
opportunities to further expand your solar farm, even if the grid is already at capacity with feed-in

500 kWh Scalable Energy Solution

The Boltainer features a modular design: you start with an initial 500 kWh unit and can later expand with a second or third container, without the initial investment becoming obsolete. No one can predict exactly how your company’s energy consumption will evolve over the next five years, and a storage system that doesn’t scale can quickly go from being a solution to an obstacle.

What that means in practice:

scale up in increments of 500 kWh or larger units, while the existing container continues to operate
a single central EMS that controls all connected containers as a single integrated system
space for future projects such as a charging station for the vehicle fleet, an additional production hall, or the transition to electric heating
an investment that grows with your business rather than limiting your plans

Frequently Asked Questions About the 1000 kWh Battery

Can't find your question here? Please contact us.

How does a 500 kWh battery container work?

A 500 kWh battery container essentially serves one purpose: to draw power when it is cheap or self-generated, and to release it when it becomes expensive or is needed for business-critical operations. Throughout the day, the container recharges using its own solar panels or from the grid during off-peak hours, drawing on that reserve as soon as the evening peak begins, a production line starts up, or the spot price spikes.

The key difference from purchasing electricity directly from the grid is that you buy electricity during the cheapest time of day, while consumption occurs during the hours when your business is actually operating—without having to adjust your schedule to match the electricity rates.

How long will it take to install the 1,000 kWh battery container?

The standard delivery time for the battery container is 90 days.

Who is responsible for maintaining the battery?

Battery maintenance is performed by our own service technicians or by a certified partner. This is done according to a fixed maintenance schedule to ensure that the battery continues to function safely, reliably, and at peak performance.

Will I be assigned a dedicated contact person to work with?

Yes, you will be assigned a dedicated contact person who will guide you throughout the entire process. Your contact person is available to answer your questions and provide support. This helps us keep the lines of communication short and clear.

What happens in the event of a malfunction?

All BOLT batteries are equipped with BoltOS, a smart monitoring system that provides 24/7 remote monitoring via a 4G/5G internet connection. In the event of a malfunction, proactive measures are taken to quickly identify and resolve any issues, often before you even notice them.

Are the inverters built into the container?

Yes, with the BOLT-20, the inverters are built into the container as standard.
