/// Context_Analysis

Why is a diesel generator a thing of the past?

For modern retail, the generator creates more problems than it solves. Turning off the lights leads to reloading of cash registers (loss of receipts), stoppage of refrigerators, and an outflow of customers due to noise and exhaust fumes.

Challenge & Problem Statement: Pause when switching

The generator needs 30-60 seconds to start. During this time, POS terminals, servers and Wi-Fi are turned off. The line at the cash register goes to competitors.

Challenge & Problem Statement: Noise and Complaints

85-95 dB of noise. It is impossible to install in a residential building or at the entrance. Constant conflicts of residents and inspections.

Challenge & Problem Statement: Fuel logistics

You need to constantly carry canisters, store hazardous fuel, change oil and filters every 100 hours.

Massive missile strikes

More than 50% of generating capacities were destroyed. Shutdown schedules of 6-12 hours have become the norm. The business lost up to 40% of revenue.

2024-2025

Lack of power

The tariff increased from UAH 1.68 to UAH 4.32/kWh. The preferential night rate has been cancelled. The business tariff has reached record values. Diesel has doubled in price.

/// FAQ

Frequently asked questions about BESS for business

So, for most commercial facilities, BESS completely replaces a diesel generator. The system provides instant switching (10 ms) without any interruptions in the operation of the equipment. With the right battery capacity, BESS covers all typical blackouts lasting up to 4-6 hours. For objects of critically long outages, a hybrid solution is possible: BESS as the main source + generator as a last resort reserve.

The duration of autonomous operation depends on the actual consumption of your object. With a configuration of 100 kWh and an average load of 25 kW, the system will provide about 4 hours of uninterrupted operation. If your average consumption is 15 kW (a typical store without powerful refrigeration equipment), autonomy increases to 6-7 hours. Battery capacity is always selected individually for your load profile.

Yes, this is one of the key advantages of a BESS over a generator. The system does not emit exhaust gases, works absolutely silently and has an IP20 protection class for the indoor version. A room with minimal ventilation and a temperature of +5 to +35 degrees is sufficient. A basement, a utility room, a server room or a technical floor - all are suitable for installation.

ESaaS (Energy Storage as a Service) is a model where you do not buy a battery, but rent energy. We install the equipment at your facility for free, and you pay a fixed monthly fee per kWh of energy used. This allows you to get all the benefits of BESS without large capital costs. The model is available for objects with a consumption of 30 kW or more and a contract of 3 years or more.

Yes, the modular architecture of BESS allows you to increase the capacity at any time. Pylontech battery modules are connected in cascade - you can start with 61 kWh and gradually increase to 150 kWh without replacing the inverter. Adding modules takes one business day and does not require system shutdown. This makes BESS an ideal solution for growing businesses.
