What in your company must not be left without electricity?

An outage can mean a production stop, data loss, interrupted cooling or a costly equipment restart. When designing backup, we therefore do not start with the size of the battery but with what has to keep running.

BESS – Battery Energy Storage System can be part of a backup solution. However, the presence of a battery alone does not guarantee backup.

We back up what has value for you.

It is not always necessary to supply the whole company. Control systems, servers, pumps, cooling or only the part of the production equipment needed for a safe shutdown may be critical.

For each load, we determine the required power, the backup time and the longest acceptable power interruption. We also take into account the nature of the equipment and its start-up requirements.

Power, time and switchover method

The same 150 kW for 15 minutes represents 37.5 kWh of energy; for four hours it is already 600 kWh. These are illustrative values excluding losses and reserves, not a design of a specific system.

Backup must be part of the overall architecture: inverter, switching, distribution, protection and control. BESS is not automatically a UPS – Uninterruptible Power Supply. Sensitive equipment may need a separate solution.

What if the outage lasts longer?

A battery has finite capacity. In a suitably designed system, it can work with photovoltaics or another backup source.

Photovoltaics do not automatically continue generating during an outage either. Their operation in backup mode must be technically verified.

Everyday use and outage readiness

During normal operation, part of the battery can help with photovoltaics or demand peaks. At the same time, a reserve can be kept for backup.

A larger reserve reduces the capacity available for other tasks. In the assessment, we therefore separate everyday energy benefits from the value of reducing the consequences of an outage.

Let's start with the critical equipment.

Tell us what must keep working, how much power it needs, for how long and what interruption it tolerates. We will add information about existing photovoltaics, a UPS or a generator and propose a suitable combination.
